Greetings

I am new to Victron. I have installed the EasySolar in an off grid setup with 9.6KWh batteries (4 x 12V 200AH LiFePO4 - Non Victron - Built in BMS) and upgraded all the firmware.

I have 5 panels in series delivering just under 110V when disconnected and about 10A in short circuit.

When I connect the panels to the unit it doesn't charge the batteries. It issues error #38 input shutdown due to battery over-voltage. I then have to go through the process of resetting the unit.

Any help with this would be appreciated.

Cheers,

Mahmm.

Hi Guy and others,

I've done a few dozen installations using the BYD / Victron combination (A multi with CCGX and 4 x 2.5kWh cells)but read somewhere about a new 'simpler' programming option. Can you enlighten me?

Cheers!

Hi Victron community

I was wondering if the neutrals in the Easy Solar 3kva ports input ( generator ) AC1 output via rcd or cb are connected when the generator input is running .

I have disconnected the men at the generator and the relay men function in the Easy solar . I am back feeding the main switchboard form the AC1 out put and men it there ?

my question is now should I have run a separate earth back from the MSB to the generator to men the generator ? or should I have left the men in place in the generator ? the inspection company is getting me for AS/NZS 3000 7.3.2

Hi folks,

I have a 5kVA Multiplus, wrapped up in an easy solar package but I dont think that matters in this context.

It is hooked up to a 13.8kWh BYD pack, all installed as it should be.

I am looking for opinions about doing a limited amount of welding, using a modern inverter based welder.

The welder would only require a single 13A supply and would probably only need to be set at about 80%, possibly less, of its maximum output.

Obviously load isnt an issue, but I am interested to know if I should be considering anything else or even if there is some technical reason that some load are not advised.

Thanks,

Al

To conserve battery power especially in low-solar times, I would like to feed power only for example 1h/day (ventilation, cameras, 4g router etc). Is it/will it be possible to program this to CCGX so that it switches inverter ON everyday at noon at OFF at 13.00?

Hi

I have an EasySolar48v 5K 70a controller charger set up in July this year. Summer has been great, the 6 x 500w panels have been rocking it. Charger and panels came from Bimble Solar who haven't given me any answers to my problems.

We have 4 x AGM 200aH batteries in the system, they're about 3 years old now.

The SOC on the colour panel has never dropped below 99% the BMV attached dropped a little more but no less than 97% ....so the last couple (ahem) of weeks have been cloudy and wet (I'm in the East Midlands - UK ) and the low battery warning has come up a few times and the controller has even switched off. But the SOC still reads 99% ???

We have a 5Kv Honda genny plugged into the AC input on the controller, when I give it power, it accepts for about a minute (in bulk charge) switches to float for about 5 seconds then cuts the AC input. The batteries remain in a low power state. Once the sun comes out, it's happy again taking charge from the panels.

I haven't had a comprehensive wiring diagram to follow, just used common sense and deciphered what I could from the manuals for each device... the one thing I wonder about is the v-sence port on the charger controller, it's not attached to anything at the moment, should this be attached directly across the battery terminals? Does this feed the metering for the SOC? Its the 2 pin connection.

Help much appreciated as I don't want to damage another set of batteries!

Cheers

EasySolar just seems to be getting more and more flakey and erratic.

Examples from today, last week and ongoing include :

• CCGX showing only bulk charging when full sun all day, should have had a few hours of float. Can see it is throttling amps.

• MPPT randomly targets voltages such as 55.3 and will sit there for hours when bulk is set at 58.8, even in full sun

• CCGX showing 0W for AC loads when loads are running
• I/O errors on CCGX when inserted USB memory stick in both ports with different USB sticks

[image]

• CCGX showing error message when ejecting UBS following correct procedure

[image]

• CCGX just stops writing data to USB stick so you end up being unable to diagnose what is going on
• Unit gets stuck running in AES mode (by display on CCGX showing “low power”) even when you are running loads

The icing on the cake came today – came inside in the afternoon and heard the fridge sounding a bit different. As far as I can see on EasySolar it was putting out 145v. Managed to insert USB and it worked so got this data which showed the following drop down to 145v :

[image]

This is what it looked like after I reset the EasySolar unit.

I’m starting to get VERY worried that the Easysolar is going to or has been doing damage to my household units.

Would my best course of action now to go back through where I purchased it as this unit has been doing funny stuff for a long time?

Thanks.

The internal power consumption is not visible on the VRM dashboard on the internet. That have become very obvious to me when the days now are geting shorter and darker up here in Sweden.

I have a 48V/3000W Easy solar and apparently that unit has a constant internal power consumption of 0.70A or 0.8 kWh/day, but that isn't shown in the graphics. I think it should, because the idea with the graph must have been to compare production with consumption? Now my batteries are heavily discharged without that being displayed. I made a modification to the last day in the picture below to show how i think the true consumption should de displayed.

(Is this the proper channel for an enhancement request/suggestion like this?)

[image]

I am having challenges with a self consumption model in the following aspects

1. after installation of EM 112 meter and activating Zero feed in , the battery module discharges providing power to both AC out #1 and 2 instead of providing backup only to Critical loads and leading to a complete outage.

2. If i deactivate the EM 112 with Zero Feed in- the PV yield is considerably low as its only feeding the critical loads .

Hello,

I Have EasySolar 48V/3000VA with the two BYD Batteries 2,5 kWh 100 Ah. I set the Absorption voltage to 55.2V and float 55V as in BYD manual, MPPT 56.5V. But my system never goes to float phase, allways in Absorption. Can I make some change and improve this? Thanks a lot

[image]

I have an Easysolar 5kVA 48V unit connected to 4 x 220Ah Victron AGM batteries and 12 x 330W PV panels. The system is connected to the RED phase of a 3 phase system feeding a large house. There are no 3 phase loads connected to this supply. At random times the inverter will enter PASSTHRU mode and feed power back into the grid, even though the GRID tab in the VECONFIG file has been set so as to not allow power to be fed from the DC to the GRID. Sometimes it will happen for very short periods but i have seen it going on for up to 30 minutes.

EasySolar 48/3000/35 - off grid.

Turn microwave on, microwave LED display dim and microwave making different noise to normal.

CCGX showing 0W AC loads (should be around 1600w with microwave), & also showing "Low Power" as i'm using AES.

Turn Easysolar unit off/on with toggle switch on front panel for couple of minutes - no change.

As a punt tried "Redetect" - no change.

Turn unit off for few seconds then turn off all loads then turn unit on and it's back to normal.

Second day in a row has done this.

Assuming it is getting stuck in AES mode somehow & why is the CCGX displaying 0W for AC loads too?

Anyone know what's going on?

After commissioning the system according to the documentation here:

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#veconfigure_settings

the GX display does not seem to be displaying correctly the battery state of charge (%). From an initial value of 100%, the % is decreasing daily, despite all 6 green LEDs being lit up on the Pylontech batteries, indicating 100% SOC. There are very few loads on the system at present and plenty of solar available for charging. Could the monitoring system be only measuring discharge currents and not taking account of charging currents? Could there be a communication issue between the GX and the integrated SmartSolar charger?

Thanks,

James

Hi All,

I seem to be unable to configure what I was told the EasySolar could do. It’s possibly my fault, but if not it’ll be a feature request that I think would potentially sell a lot more victron units in Australia.

If one selects “grid code” of “none” it seems I cannot use PV power unless in powerassist mode, UPS (in Ac-in fail) or batteries need charging mode. Ie under normal operation (grid/generator present) PV power will reduce as the batteries charge, and even though I have 1.6kw of panels I’ll see charging of just 20w etc.

ESS cannot be started with a grid code of “none”

ESS cannot be started using the Australian grid code (it warns that a secondary relay is not present in the product)

Selecting UK (and others) will allow the ESS to start and one can then select “use excess PV power to feed into the grid” which then will use all PV power available (Which majority of the time is lower than the load).. but obviously this would be non compliant (and therefore illegal) if running without an anti-islanding relay.

I have also noticed I have to set “keep batteries 100% charged” for it to work, using “optimized” will cycle the batteries.

Setting “power assist” will work sort of... if I set the limit input to 4.5A it will use a couple of hundred watts to power the load, however it will never use less than 700w no matter if I set the input limit to 0.5A... (it just sets itself back to 4.5 in the GX) ... and worse (for my situation) should the load go over the available PV power it’ll discharge the batteries.

So nothing does what I want to do.

I want to use the easy solar as a UPS and have the PV power reduce grid power. Ie:

I have “cranker batteries” (24v 200Ah flooded flat lead plate) so they should be just used when there is a grid failure. Grid is stable for most of the year but I have a lot of computers hence needing/wanting to use “UPS” mode. I do not want to feed any power into the grid,.. just downstream to the loads. If there is excess PV power after the batteries are charge and the grid consumption hits zero just reduce the output of the MTTP charger. (This is got local regulations compliance... domestic premesies are not allowed to feed in more than 6kw of power.. which I wouldn’t anyhow, but as a consequence no installer will install greater than 6kw without an upstream limiter and non seem to want to do Victron stuff.. so I’m installing them (EasySolars) as UPSs for each power rail in my mini DC.. i’ll End up with >6 of them and 18kw of panels if they can actually do the job I need.)

Thoughts/direction welcome.

Hi All,

I am converting a school bus and have heard rave reviews regarding the victron brand - however I am finding it difficult to establish which combination of products I would require.

My partner and I plan to source our own Panels (4 x 140w Panels = 560w)
My partner and I plan to source our own batteries (4 x 120ah Fullriver DC Series AGM Batteries)

But we are seeking advice for everything in between. Inverter charger/ MMPT/ moniters/ fuse box/ distribution ...

We anticipate primarily using DC power, for the lights/ fridge/ water pump/ most general electronic devices.

We anticipate using AC power generally for low draw appliances ( RV washing machine, laptop) and on rarer occasions the following high draw products but only one at a time ( microwave, hair straightener/ sandwich press). Because of this we anticpate needing a higher rated inverter.

Please advise a product that is compatible with the battery/solar capacity, usage requirements and as price effective as possible.

Additionally, please suggest the simplest combination of products. I will be installing and I am no electrician! I was drawn to the EASY SOLAR due to the compact single unit, with prewired internal components.

MUCH APPRECIATED

What type of inverter configuration is incorporated in the MultiPlus 24/3000/70-50?
Does it incorporate an isolating transformer?

or is it transformerless?

If it incorporates a transformer can you please let me know the impedance of the load side winding?

I am attempting to calculate the external part of the fault loop impedance (equivalent grid side impedance) for an installation (house load) that is connected to an EasySolar 24/3000/70-50 (which incorporates a MultiPlus 24/3000/70-50) as its sole source of supply?

Thank you for your time and help with this.

Good day.

1) My Multiplus inverters in my EasySolar systems supplies the load correctly when drawing power from the solar panels and battery bank. However, when attempting to activate AC input from the grid, the 63 A RCD output breaker trips after about 30 seconds. I have measured the voltage between earth and neutral at the grid input side and there is a 0.440 v reading. This should be 0 v if I am correct. Could this be tripping the RCD and if so, can I bypass this RCD and go straight to the circuit breaker after it, which is part of the EasySolar system?

2) My ESS setup brings the low voltage light on and prevents the inverter from inverting. I have set the parameters up correctly as suggested on a previous post but still have problems.

Please help as this setup is giving me endless problems. Thank you and kind regards,

Is it possible to use the 12V 1600VA Easy Solar in VRM over Internet with an external Colour GX?
I ask since the Easy Solar versions with a built-in GX is 24V only.
It would appear that the charger is different hardware that require a separate USB interface to be externally controlled.

So can the VRM be used at all at all with this unit with regards to the charging and inverting?

Many thanks!

For what duration can the EasySolar 24/3000/70-50 deliver its rated 6000W peak power?

Is there a corresponding maximum operating ambient temperature limit for this rating?

What impedance in Ohms will the EASY SOLAR - Multiplus 24/3000/70-50 contribute to the earth fault loop impedance of the stand alone power system of which it is the sole source of power supply?

Hi All.

I have searched the community and I do not seem to get an absolute answer from the posts.

I have just installed an EasySolar 48/3000 - I have an ESS with Energy Meter ET112.

My supply is separated into Non-Essential (Stove, Geysers etc) and Essential Loads. My Non-Essential loads do not run thrrough the EasySolar AC-out2, they have a dedicated Switch Board.

Essential Loads run through the EasySolar AC-Out1A and 1B

The issue I have:

When the EasySolar is configured in ESS as Optimized with BatteryLife, and a Non-Essential load (Geyser) is switched on, the Non-Essential load starts draining my batteries at an alarming rate. I have noticed that the AC-IN of the EasySolar actually becomes an AC-OUT and powers Non-Essential loads to the max rating of the Inverter.

Is there a way to tell the EasySolar NOT to power the Non-Essential loads at all?

I would like the Non-Essential loads to be powered from the Grid Only to be able to preserve Battey power for the Essential Loads, in the evening, or when there is no PV power.

Thanks for the help.

Easysolar 12/1600/70 AC output pulses under load, Has latest firmware updates as of the 30/9/2019. when running a small loads 10 to 20 watts OK, when running more the 300 watts the AC output pulses between 230Vac to 200Vac and lower? load was a heat gun as an example.

Battery is 12v 800Ah AGM pack and fully charged to 100% SOC voltage does not dip down below

13v under the 300 watt load.

The main torroid transformer buzzes very badly.

This is a new install.

Having seen the product news for EasySolar II at Intersolar, I wonder if there is also a new EasySolar for 5 kVA in the queue for new products this year or next year? if so, when will this be available?

Hi all,

i'm struggling to get my solar set up to charge the batterie of my battery bank.

The solar panels give the right output voltage of about 37-something volts but 0 Amps and Watts.
I've tried resetting and re-detecting the system on the EasySolar unit to no avail.
Also it gives no errors in the notifications section of the menu.

I reckon it's something relatively simple I've been omitting but I just can't get my head around it...
Any ideas and help would be appreciated.
Also let me know if you would require some more information if needed.

Here are the specifications of my set up build in on a MAN 4X4 overland camper truck.

5 x Canadian Solar CS6K-295MS panels (1475W in total).
One set of 2 panels and one set of 3 panels.

On the picture the panels are not wired up yet but you'll get the idea.

I have a small office with fairly low daily electricity use apart from the depths of winter where we might run a electric heater.

Basically just two desktop PCs, a laser printer, router, cordless phones, a few LED lights, kettle, occasional microwave use if want something warm for lunch, 8 hours a day Monday to Friday.

Its got a mono-pitched south facing roof, so plenty of useable space for panels.

The building is only rented, so don't want to spend a vast amount on some feed-in type setup with export meter selling the excess, I just want to try and make the majority of what I use, and at the same time save a bit on the electricity bill.

I am struggling with what option to go for, as want to try and get the biggest benefit from what I have to spend.

I am tempted to go for a SmartSolar 100/20 (on 48V) and going as close to the full 1160W as I can on the panels, 4x 12v 100Ah-ish batteries, and then use a Phoenix 800VA (on 48V) inverter to run all the low powered stuff, PC's, Phones, Lights, etc... and leave the Printer, Kettle, Microwave and Heater on the grid. And in the winter if I struggle for solar power I could move some or all of it back onto the grid.

Is the fact I will be using the power during daylight hours going to give the batteries a problem? As they are probably only going to get back up to float during the weekend when there is no drain for a couple of days.

Or is it one of those things where I just need to bite the bullet and do something, and if its not enough I will have to swap something out for something bigger, or add another MPPT controller at later date.

I really do like the idea of the EasySolar how its all in one box, but unless I spent serious money and went for the 3kVA one, the 1600VA (on 24V) doesn't really let me run much more PV than the 100/20 (on 48V) but obviously could pull from the grid automatically if there wasn't enough PV or Battery, rather than me having to manually plug stuff into another socket.

Or to really throw a spanner in the works, when I look at the example layouts the Multigrid seems ideal as has enough power to run everything through it, and I could run a surplus of panels on a normal Grid-Tie AC type inverter, but set the Multigrid not to export the excess, and it would use the battery bank to fill in the gaps in the solar, and would only fall back onto grid if there wasn't enough solar or battery.

Any ideas or advice is greatly appreciated.

Good day all

We are in the process of setting up a brand new solar system using 12 x US3000 Pylontech batteries connected to 2 x EasySolar 48/5000/70 systems. A pylontech low voltage comm. hub is being used. I would like to know where the inverter output cable of the low voltage hub is connected to the easysolar system and what communication cable is needed for this?

Could someone also explain how I connect the two easysolar systems in parallel.

Thank you and regards,

Hi folks,

I will be hanging new PV tomorow morning and would apriciate some input.

I have a new Easysolar 5000 hooked up to a BYD 13.8 kW Lithium pack.

Obviously I will set the MPPT as directed in the manual, which I havent read yet, but I am also aware that the BYD battery manager, via the CCGX is going to 'manage' things.

What I dont know is how it will manage things, what I should look for to establish that all is well and if I need to make any changes to the MPPT settings, which I assume I will.

My supplier told me I needed a programming cable, USB to VE Direct I think, which I have but I havent found what I should be doing with it yet...

I still have manuals to read but the BYD manual dosnt mention MPPT settings, speciffically, and thus far I am unsure what software I need to program the MPPT in the first place. In addition The manuals for Victron kit havent, so far at least, been speciffic about BYD kit and I am not expecting the MPPT manual to be any different.

Am I correct in assuming I unplug the cable to the CCGX to program the BluePower and if so is VEConfigure what I need or something else.?

Any help/pointers would be appriciated. I am pretty sure there is potential to get this wrong and I would rather not do that, damaging 6k's worth of battery because I used the wrong setting is not a place I want, or can afford, to be.

Thanks, Al

I have an EasySolar 24/1600 that I'm looking to tie into my vessels sensor / monitoring network.

From reading this article it looks like the recommended approach has been to bridge both the VE.Bus connection from the internal MultiPlus and VE.Direct from the MPPT direct to N2K. In the comments section though there was talk of a CCGX -> NMEA integration. Is this still something on the horizon?

I'm assuming it will apply to the Venus GX too? If so, that would be a much neater integration (VE.Bus and VE.Direct -> Venus GX -> NMEA) as well as providing a couple of additional sensor inputs.

On a slightly related note, has there been any consideration for providing a direct Signal K interface from the Venus / CCGX?

Hi there,- have a stand alone off grid EasySolar 1600/12.

It has PV and batterys,- they charge fine and are full.

There is NO connection to the mains grid.

There is a buzz / hum from the inverter [torodial transformer] which was not there when new.

The inverter works fine and produces power,- very nicely.

This hum is there even when the mains power output connector is unplugged from the bottom of the inverter [so not even wiring or socket connected!]

the hum is NOT the cooling fan,---this is stationary normally but does kick in under load.

The inverter did not make this noise when first fitted.

I would appreciate any advice but I feel that this unit should be returned to victron

Regards JULIAN.

Hi all

Looking for a bit of help. I have the Easysolar 48/5000 with the BYD 13.8 Lithium Batteries.

I have connected a generator to the system for charging the battery. I have two genets one is a 2000w and the other is an 8500w and both are AVR.

*) Force to float and set SOC to 100% when battery full and switch to charger

only when battery empty.

(note: I believe that the second part of the assistant needs to be changed as it would only use float while charging)

I set the config from this page on the Victron website HERE

Total size of all assistants including the required

(hidden) system assistants is: 198

so before I added the assistant the small genset would charge at 700w.

The big genset would charge at 1200w

[image]

After adding the Assistant and updating to the config above I got this.

Which is the same but seem to charge faster about 3-4% in 15 minutes.

[image]

Sorry could not get the images to rotate even turned one upside down but still uploaded upside down.

All firmware is compatible in the system.

My question is why does it take so long to charge the battery with the latest config and why am i only get 1500w and not 6000w? or is this normal?

Edit: Ok have just been talk to ALPS and noticed that SOC on the multi is switching from 100% to 67% for a second then back to 100%

Any info would be appreciated.
