Easysolar II GX 3000VA Venus WiFi issue

I installed a 48V 3000 Easysolar II GX in Feb this year, when I was commissioning the plant and setting it up on the portal we had an issue with the Wifi network from the Venus and for the life of me couldnt get it to come on again. Does anyone know what we can do to sort this out? I know on the Venus you can reset the wifi network but with the Easysolar its not easy to get to the Venus.

Connecting a Generator to Easysolar IIGX

Hi guys,

I'm scared...

I have connected a cable to my Easysolar IIGX ready to connect a generator for supplemental charging on cloudy days when I still want to run bigger energy draining appliances. I am confident with my wiring, and have connected to the correct 'AC in' (as per manual). Now that it is time to test the generators charging capacity I realise there is very little info surrounding this in the associated literature. I do not know what to expect to see upon successful charging?

The manual also states in section 4.1.7-4.1.9

PowerControl – maximum use of limited AC power

The product can supply a huge charging current. This implies heavy loading of the AC mains or generator. Therefore a maximum current can be set. The product then takes other power users into account, and only uses 'surplus' current for charging purposes.



All settings can be changed with a PC and free of charge software, downloadable from our website www.victronenergy.com

. See this manual for more information - https://docs.victronenergy.com/veconfigure.html

I am wondering if it should be ok to start my generator with whatever 'factory settings' are in the unit...as I have not Installed/used VEConnect in setting up the unit...only the 'Victron connect' app which gives very limited adjustment to the system? (battery voltage, float/absorbtion etc...)

It is a very simple system, 6xPV's with one 48V Lithium battery only...and is working very well.

I do not want to hurt the unit, it being my 'off-grid' full time supply.

EasySolar stuck in Storage mode

I own an EasySolar system comprising of a Multiplus Compact 24V/1600W/40A and BlueSolar charger MPPT 100/50 (Rev 2) fed by 4 x 250W solar panels, with 4 x 12v/170Ah Victron AGM Super cycle lead acid batteries as storage.

If I run the system in the “Batterylife” ESS option, the batteries discharge to the SOC level(s) – 80% - at which point the solar charger appears to become disabled and all appliances are left running on a grid feed.


Changing the mode to “Keep batteries charged” re-enables the solar charger, thus allowing solar to run any system load, and slowly recharges the batteries back to full capacity over a week or so. At night, any system load is met via the grid feed however, rather than from the batteries.

If I reset the system from the Color Control panel (MultiPlus Compact >Advanced >Reset), this succeeds in shifting the system from Storage to Absorption/Float and rapidly recharges the batteries, as well as allowing them to power any system load overnight.


However, after around 48 hours the battery voltage drops and the system then reverts back to Storage mode.


The batteries discharge to the SOC level, which disables the MPPT and requires me to intervene again as above.

The company that installed my system initially attempted some remote fixes, but did not resolve the problem. They now no longer respond to any contact from me.

I understand from this forum that this is not an uncommon problem, although solutions appears to be scarce. It seems that the Storage mode can be disabled via the VEConfigure set-up system, but I am not trained to do this myself, nor am I certain if this would fix this problem.

Just wondering how to get the system working properly, any advice appreciated.

Multiplus vs Easy Solar

I am trying to work out why I would use a Mutliplus 48/5000/70 and a separate MPPT 100/50 Solar Regulator versus using the EasySolar 48/5000/70-100MPPT150/100 all in one .

The only extra feature I can see is the Power Control feature on the Multiplus - which it seems can be done anyway via the Colour Control Panel on the Easy Solar. Also the easy solar has AC distribution and Colour Control Panel etc

When i compare the cost it seems the Multiplus and Regulator and Colour Control Panel will cost quite a bit more more than the same Easy Solar?

Feel Like I am missing something? Anyone have any ideas on any more advantages of the Multiplus setup

EasySolar ESS randomly switches charging-discharging mode

hi, when charging or discharging battery in ESS mode, EasySolar 48/3000 / 35-50 randomly switches mode - float / discharge, bulk / discharge ... This is repeated approximately once time in 3 minutes. Behavior is the same as at minimum power and at maximum power.

The strange behavior of the inverter is seen on the video

Firmware on all devices is updated. I use 1f grid meter and Fronius Primo in AC OUT, grid setpoint -20W. In several posts, a similar behavior of the inverter has been solved, it has always been solved by new firmware. I have the latest firmware - 433.

Virtual switch settings on VeConfig

270W solar panels- EasySolar 48/3000 (Multi) with MPPT 150/50- 4x200 Ah gel batteries in series for 48V . BMV 700 - CCGX Color control. No Grid feed in allowed . Grid available for AC IN.

I am having serious difficulties setting up ESS / Assistant with VEConfig.

When looking at what Virtual Switch can offer, I realize this is far enough for what I want to do.

1_ Use as much solar as possible to recharge the batteries ,

2- Set VS for Grid ACIn to come ON when batteries are too low (50 V) or when a heavy load is powered .

I have set up VS on VEConfig . All seem OK; I have "sent" the settings .

However, I do not see my Multi behaving according to the VS settings . Example . i have SET AC IN "ON" if more than 3000 W is requested , or if batteries get lower to 50 V.

Right now my batteries are 52 V, and my AC OUT loads are 500 w.

Until I solve the VS settings problem, I have my EasySolar "ACIN" breaker on "OFF" as I do not need , nor want any AC IN .

If I turn on the AC In breaker with these voltage / Watts described above, my AC In comes in ? It should not.

Did I forget something after setting VS on VEConfig ?

MPPT 100/50 - 1 PV input shorted from 3 available PV inputs?

I have installed an off-grid EasySolar 1600 with 24V battery (2x 12V) and 3 solar panels. I connected them to PV input 1, 2 and 3 of the EasySolar (MPTT 100) and sadly one panel connection was reversed and although it should be reversed polarity protected the input (of entire MPTT?) was blown. Saw the smoke coming out and smelled it, from which I draw the conclusion this was really burnt out. This was on PV input nr 2.

I disconnected this input but the other inputs seem to be working. As I have no more monitor (BMV7xx) in this system I cannot see the battery charging levels but I do see the bulk led on with the other PV inputs correctly connected. Is there an easy way to be sure it still works correctly?

Could it be that the 3 PV inputs are internally separated and separately fused so only PV input 2 is affected?

Have just received my 24/3000 easysolar for my stand alone power system.

Its replacing an old Selectronic SA22 and controller, thats still working good. We're revamping the entire system . Batteries, panels and inverter.

Because the SA22 is connected directly do the house fuse/relay box am confused. The SA 22 only had a power point on the front, 35m2 cables going to the batteries, and then a power line going to the fuse box.

When I disconnect the SA 22 can I just run a line directly into the easysolar from the fuse box?

Where does it get connected to on the easysolar?

I'd rather keep the fuse box in place.

EasySolar 24/1600/40-16 inverter when supplying asymmetrical loads.

I’ve noticed when an old 900w hair dryer is running at full power the EasySolar runs quietly with a low level buzz. After a while the cooling fan will operate.

However when half power is selected the buzz from the EasySolar (transformers?) is most pronounced. I surmise the half power setting on the hair dryer is likely achieved by a thyristor chopping the current waveform in half.

Will any damage to the inverter ensue from this mode of operation? Are there implications for the longevity of the EasySolar if this type of load were to be sustained?

Reason tells me not to use the half power setting of the hair dryer. But it was only noticed by accident when temporarily depleting the battery charge while setting up the system.

My concern is, at a future date, I intend to use the inverter to power an air-source heat pump which has an ‘intelligent’ compressor mode to optimise efficiency.

My concern would be how the EasySolar’s inverter would handle the compressor (stated steady consumption 470 watt) if it provided an asymmetrical load when in ‘optimised’, reduced power consumption mode

Any advice please?

Easysolar II - specific scenarios

If someone can clarify if these scenarios are possible, I would be most grateful. All these scenarios are for off-grid use with ac being only used to supplement the solar power and not to feed back to the grid.

When PV is providing power


Use PV+Battery for all loads. If exceeding the load capacity of the inverter/battery, then pull from the ac mains seamlessly. Otherwise ac is not used.

When PV is not providing power (low light/night)


Use battery for all critical loads. If battery depleted switch to ac. Do not charge battery from ac, but charge next day from PV.

Use ac for non-critical loads. If ac power fails, switch to battery for these loads automatically.

How much airflow per watt of inverter load?

As much as I'd love to mount my Phoenix 12/1200 in free air, it just has to be in a compartment. I can add all the fans I like, though. How much is enough?

The Phoenix datasheet quotes its "max" efficiency at 92%, I'm going to be a little pessimistic and figure 85%. If 15% of 1200 watts is turning into heat, that's 180 watts I need to move.

Hey, that's pretty similar to the TDP of an average PC, which is adequately cooled by a pair of 25cfm case fans, so I figure something like 50cfm ought to do it. I'm looking at a fan rated at 62cfm, maybe I only need one of those.

There MUST be a more rigorous way to figure this, but all the formulas I find require you to know things I don't know, like the thermal resistance of my heatsink. (Okay, that's internal to the Phoenix, and anyway, it has its own fans so I'm lost at how to even begin.) Does my cocktail-napkin math sound sane, at least?

Also, since I don't have the unit in-hand yet, does anyone happen to know which side of the Phoenix is its intake and which side is the exhaust? The manual says not to mount it with the fan on top, but I can't tell from the photos which side that even is.

Thanks in advance!

Easysolar 12/1600 install in a van, panel wiring and LiFeYPO4 settings


Bought into Victrons sales speech for Easysolar 12/1600 product for a van project, but it seems some things still remain unanswered. I've read the manual and done the search. This setup will be used year round in different locations, some shaded some not and temperatures will vary mostly between -5 to +25 celsius. I will be living off-grid full time in the vehicle, so i opted for what i believe is a quality product from a European manufacturer, and i really want to like it.

Being that solar power is somewhat of a new option in the energy market (for the average consumer i mean) and it's popularity will grow together with the advance of battery technology. I find that that the manual and available information for a product labeled as Easysolar is lacking. I really think Victron is on to something here, but the documentation needs to be improved.

Ranting aside, to avoid frying my expensive gear and to get this right the first time, i have come here at the fountain of knowledge to be assisted and educated. So please take time to read this post thoroughly.

My setup will be:

Easysolar 12/1600


3x GWL SunnyPoly 165w panels


12v 260ah LiFeYPO4 winston battery with BMS123Smart for monitoring (link is to 200ah battery, otherwise specs should be similar)


Now for the list of actual questions:

1. Series or parallel panel wiring:

-I am under the assumption that parallel wiring would be better for shaded areas, but series better for more challenging conditions. So far I'm going for parallel wiring, will this work? Do i have enough voltage coming out of the paralleled panels to charge my system when in less optimal conditions? Is there a reason i should consider series?

2. If wired parallel, where to connect:

-there are inputs for 3 strings of panels on the Easysolar, is there a difference whether i connect the panels parallel in the roof and come down with one set of connectors and wires or is it better to wire and connect all 3 panels separately? I am inclined to wire them separately just because it would seem more serviceable and more robust to have less connectors and all 3 panels having their own set of cabling all the way from panel to the CC, this make any sense?

3. Inverter/charger settings

-i do not have any kind of color control monitor or such, i only have one VEdirect to usb -cable which i gather is not compatible with the inverter/charger portion of Easysolar but would need a VEbus to usb cable(?). However, when i check the manual page 16 for the table for dip-switch operable voltage settings - there is no setting for lithium batteries to be found at all? What settings do i NEED and HOW to set them now (with either dip-switches or by acquiring the VEbus-cable)?

4. Charge controller settings:

-now this one seems to have a rotary selector for LiFePO4, so that's something that is finally Easy as the name suggests. Apart from flicking the switch to seven is there any additional settings i NEED to change in order to keep my battery healthy? I quess this would be done with the VEdirect to usb cable and a computer then?

5. Is there anything else i need to reconsider before going with this setup?

-i've already acquired the gear mentioned above and will install these in the coming weeks. This will be the single most important aspect of my van, so i would like it to work since it will be a pain in the ass to redo once the project is finished.

Thank you for reading this far, please reply if you have an answer to one of my questions.
