Hi there.


I'm in the process of making a list and trawling through all the documents I can find on how to pair the BYD batteries with a Victron EasySolar or MultiPlus for an off grid setup. Basically, my setup will be as follows:


All control gear and batteries to be stored outside, but under an awning.

2.8kw of solar, which will work with a 150/70 MPPT charger.

BYD B-Box RESI IP55 cabinet with 5.12kwh battery

Either the Easysolar 48/3000 or the Multiplus 48/3000.


Can anyone who is familiar with this combination tell me if there is any advantage to choosing the Multiplus unit over the Easysolar? The Easysolar works out cheaper than buying all the parts and cables individually, but I've noticed that the IP rating on the Easysolar is only IP20 though, so maybe it's not suitable for installations outside?


Any thoughts or suggestions would be much appreciated.


TIA

Hi...

I have "Keep Batteries Charged" configured in ESS, but my system charges the batteries constantly and never goes into an "idle" mode (or perhaps pass-through mode).

I've configured a separate larger system and noticed that the batteries are charged once, then no more activity is seen on the CCGX and the VRM portal shows "idle".

What setting could I have wrong in this configuration?

Color Control GX (v2.42)

MultiPlus Compact 24/1600/40-16 (v465)

BMV-700 (v3.10)

BlueSolar Charger MPPT 75/50 (v1.47)

2x Monbat 12MVR170 AGM (closest spec https://drive.google.com/file/d/1ha7IVahv56O-qEzJJKgZfcrXlrKLLlPL/view)

2x SunLight NetForce FT 12-180 AGM

Float Voltage set at 27.24

ESS: Enabled

DVCC: Enabled

Hi all, my CCgx panel always displays 100% battery even when voltage drops to 48 and below. I have 8x 6v AGM 550amp batteries and No grid input, purely 4kw of pv panels for an input of 120v (4 in series x 4)

I have updated all firmware to current (2020) versions with no change

I installed a 24/1600/40 Easysolar with two 220Ah Victron Gel batteries six months ago into a small residence. The unit powers lights, refrigerator, WiFi and tv. The system has functioned well until about a week ago when it started going into “alarm” mode - red led on - about 3 to 4 hours after sundown. Closely watching the battery monitor it appears that when the battery SOC is below 85% and the fridge turns on, the inrush current of the fridge is dropping the battery voltage to around 18V (the battery current as registered on the BMV700 is in the region of 50 amps during inrush) The inverter registers low DC voltage and disconnects. This “alarm” is not a problem when the solar is active - in that case the battery voltage hardly drops at all and the registered BMV current is around 30 amps. Is this normal, or is there something wrong with the batteries? I have used the default settings on the Easysolar as delivered by Victron which, looking at the settings, appear to me to be optimal for the configuration.

Hi, i want to know if i have any risk of damaging anything if i disconnect (rotary switch 300Amps and shut down battery) the BYD battery from EasySolar when PV is connected at Night and during the week end. I don't want to leave the new installation "alone" for the moment.

i've see here many differents answers but no one really match my case...

I understand it can not dammage the MPPT but it can occure an overvoltage when i disconnect it, that's right ?

Thank you

Hello. I have an Easysolar 12/1600/70 which is connected to 480AH of LiFePO4 batteries and 1100W of solar panels. (The system also has a Smartsolar 100/30, but that is not relevant to this question.) I have the equipment installed in my RV, which has a small front-loading washing machine in it (Dometic WMD 1050.). The washing machine will not run successfully on the inverter, no matter what I try, yet the same washing machine will run successfully using a Honda eu10i (1 KVA) inverter generator. Curiously, if I plug the generator into the RV and use the Easysolar inverter in power assist mode, the washing machine will not run, but it runs fine if connected directly to the generator.

The symptoms are: The washing machine will power up. A program cycle that does not use the water heating element can be selected. The machine can be started and the water solenoid will open and allow the washing machine to fill. During this process the bowl of the washing machine rotates slowly, as it is intended to do. Once filled, the machine switches to the wash cycle and the motor attempts to rotate the bowl, but it only rotates about 1/4 of a turn and stops. It repeats this process endlessly. When connected to the generator, at this point in the process, the bowl rotates correctly.

I get no alarms of any sort from the Easysolar 12/1600/70. No low voltage alarms (I have set the input DC low voltage cut-out to as low as it will go) are recorded on the alarm list.

Before I installed the Easysolar, I had a cheap Chinese-made 1000W, pure sine wave inverter and it would run the same washing machine with ease. This is very frustrating as I have invested a lot of money into the Easysolar, BMV, Colour control GX, etc and it is not performing a fairly straightforward function. The same inverter will run an electric toaster and my wife's hair-dryer, both of which are rated rated at 1200W, without any trouble. I am assuming that the inverter does not like the inductive load, or the 240VAC waveform of the inverter is not good enough for the washing machine when under load.

Can you suggest any settings that I may have wrong, that are preventing the washing machine from working?

Thank you.

Hi, i don't find informations about BMS settings in the MPPT menu. In the BYD installation and settings tuto, you don't speak about this parameter.

A second questions is, with the new victron connect we can import config file and upload it to the device, is it possible to made a collection of config file or an user config repository for this type of product (batteries) ?

Hi, i experience some difficults to understand the grounding relay system in a Motorhome. In Many Diagram i've seen the ground (the ground point inside the easysolar panel where Ac in and Out ground should be connected) connected to vehicle chassis, for that OK.

Now, questions :

-Because of the built-in RDC inside the easysolar, should i connect the ground relay? And how?

-In my case i use a BYD Pro 10kw battery. Should i connect the ground of the box to negativ pole and to chassis? Or this already done inside the easysolar?

I don't have à DC distribution bus bar like in the byd/victron diagram ( https://www.victronenergy.com/live/_media/battery_compatibility:byd-example-diagram-2018-07-21.png

In my opinion, it's difficult to find this Kind of informations for easysolar. The diagram always shown Multi and/or mppt etc... Maybe victron can made some specific diagram for easysolar, and the use in a vehicle? (or maybe it already exist but i didn't find it...)

How does coulomb counting work in an EasySolar inverter when there is no battery monitor and the battery bank is not a Victron product?

Hallo !

For the second time this summer I have lost data in VRM - no data on dashboard or in advanced

(the system itself works fine :-)

The first time was in July, and I found out that it probably was caused by an update on July 14th.

-see post from that issue here:

https://community.victronenergy.com/questions/24318/missing-data-history-in-vrm-easysolar-24-3kva-july.html

The same thing happened on the 10th of august, which i rectified on 14th of august.
(I am not sure, but I may have switched og the main "output" switch on the 10th of August -but this shouldnt affect the CCGX/VRM /data history....?)

Both times I have rebooted the system (on site) and solved the problem.

(The system is on an island away from where I live (in Oslo) I have no means of checking on the system when I am not there.)

Very curious to why this happens....

Hallo !

From approx 13:30 on the 14th of July I have no data in VRM. The system itself is working fine - but I am frustrated over that I can not follow my system remotely.

Any tips on how to resolve this?

[image]

I have an Easysolar 3 kva with 10 kw lithium ion batteries and 1800 watt of panels.

However, I do get the most important realtime data under the dashboard graph chart, and the CCGX on the Easysolar works as it should.

Thanks,

Eric

simple question - what can I do to bring the temp of my inverter/reg and batteries down (running easysolar 48/5000 w/ 10kw BYD lithium). Can I bring the inverter units fans on prior factory setting? other options?

Cheers

Hello All

I have Easy solar 48/5000 (3 years old). the MC4 terminal on the MPPT got burnt. I replaced the original MPPT (150/100) with a new MPPT (150/100). the new MPPT is not producing any voltage even though the PV input voltage is 132V. the MPPT is also indicating "FAULT" on the CCGX.

How can I resolve this problem.

Thank you

How can I reset the VE.Bus or what else can I do to work make the CCGX/inverter work with DVCC and the BMS of the batteries?

Hi, i've opened my easysolar to connect the differents wire and i see a 200Amp fuse. On the documentation (Multiplus 48/5000) i see i need a 200 amp on the cable between EasySolar and batt. Is it usefull ? Or just a redundancy ?

[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.

Hello all together,

can I use EasySolar 2 with BYD B-Box 5kWh for 1 ph off-grid system.

Thank you for the support!

Hi,

I've an EasySolar 5kvA (not ready to use now) and i want to know if it's possible to connect an emergency cut off switch for 220V Output (and also cut off the 48/24 and 48/12 inverter) ?

Thank you :)

I have an EasySolar 48/5000/70 and I need to connect my PV panels to it. The male and female MC4 connectors at the bottom are not labeled and I can’t find a wiring diagram showing these in detail. Can anyone help? Thanks

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 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.

Hello

I have an EasySolar 48/5k/70a that is being very temperamental when it come to charging from AC from my genny (7Kva Honda).

It's pot luck seemly as to whether it will charge from it or not. I'm firing the genny manually.

The SOC on the Colour Controller is always showing 100% even when the BVM reads otherwise, the BVM is connected to the Colour Controller. The BMV reads 80% when the voltage across the batteries (4 x 200aH AGMs) seems low (46v across the bank)

The days are cloudy and dull so I'm having to (try) charge on a daily basis. Tonight it won't accept it at all. Previously it accepts the power for about 20 seconds, then rejects it, then accepts it again until it gets to about 90% SOC (on the BMV) then stops charging.

I have watched the AC power input and it rapidly rises to 3Kw and sometimes 3.2, sometimes this seems happy, others not. I see in the menu that the current limit is 40a but at 3.2KW this is way more.

The colour control is not ethernet connected so feels quite restricted in what I can alter but is there something I'm missing here?!

Any help is very welcome, I don't want to loose these batteries yet!

Cheers

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?

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.

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

Fash

But the batteries are charged

Configuration: Easysolar 3Kv (Multiplus 48/30000 + MPPT 150/70 + 2 Pylontech US2000plus as an offgrid system) I had it installed with BMS managed by the batteries (CAN.Bus/DVCC...)

One day I switshed the inverter off and after that I noticed that it doesn't start again Showing low battery :-0. Only if I connect the generator it comes back to live...

Just to see were I am I went back to first running setting: BMS automaticly managed by the MulitPlus ...deactivated the DVCC, CAN ect. (MPPT error #67, reseted MPPT) still no change.

In the VRM the low battery is displayed as VE.BUS error.

Any suggestion? THX

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!
Diamond
