Replacing the inverters (3) is not an option since it is expensive, also batteries are not compatible with other brands. A surge protection device with time delay should be able to do the job, once a disconnection happens then it gives few min to connect again. But whether a quick...

Good, but does it activate during the inverter's quick power transfer? I see it costs around 300$, it would be 1500$ investment for my 5 ACs if it works well. https://www.microair.net/products/easystart-364-3-ton-single-phase-soft-starter-for-air-conditioners

When the electricity grid connects or disconnects, there's a quick interruption that makes the lights flicker. This happens because power is being shifted between the grid and batteries, or the other way around. Usually, this isn't a big deal except for air conditioners and fridges. I've got a...

It sounds normal to me that AC load should be equally distributed over paralleled inverters but in not in the case when 1 inverter has more panels than the other, the inverter is not pulling all available power from PV to power the load when AC load is equally distributed. DC charging is...

Hello, curious to know if the reported problem was resolved by new FW? My problem is very similar, not completely resolved but improved with the capacitors, I am still looking for a solution The magic number when the PV starts dropping is above 2300w, anything below is very stable, above...

I am having this case since day 1 installed, as per reddv1, Growatt responded they will send him a new firmware and it is unlikely they will send a new firmware to address other issues, he reported this issue only. Not sure why it was working for you well then stopped after some time? maybe...

Hi, did you receive the firmware from Growatt to resolve the reported problem? If yes, can you please share it?

Not sure about wiring, I have the below contactor, I have the line power coming from the photocell I call it L1, and i have another power feed from the inverter I call it L2, I call output from the contactor as L3. I should connect L1 and L2 to the contactor and it should work in a way to...

I was always wondering why the inverter does not show how much the PV have unutilized available power? I understand this all depends on many factors, sunlight, temperature, orientation, angle, cabling, etc... But can't this calculated as an approximate value from PV volts by applying certain...

Yes, i have the same impression, purchased and installed 4 pcs in parallel since 6 months and they are doing very well.

This is good, have you ever used them for the same explained purpose ?

But this will disconnect the battery and causes the inverters to shutdown. This is how my inverter works, it doesn't work without battery, moreover, if i suppose the inverter will keep working without battery only on solar, i have other appliances in the house that are critical and should...

There are some inverters having such feature called TWIN, they have a second output for non critical appliances, but my experience was bad since they are not well built and having design defects. But if i manage to automate testing and controlling on/off based on battery voltage or SOC then i...

The title sounds strange but i couldn't find any better summary for a title. In an off-grid system, using lithium batteries, PV and inverters, during winter, non critical devices such as water heaters, water pumps, heating system, consume high power, I have installed timers so they operate...

Ok clear, thx

No, I will try, but if it works in SBU then i consider it as a bug, this means the inverter thinks utility is feeding back in while actually utility line is cut. What is this option called in other inverters? i.e. Battery SOC% for AC output after low SOC cut off? if such settings is not...

There is no settings on the battery, settings is from the inverter only, soc is set in program 19 in the attached manual of the inverter, also i have attached the battery manual

It's voltronic lio ii 4810, bms connected, battery detected using lib battery type on inverter as per manual

Already done this and couldn't find it, what is this settings called in the inverters you know?

Meanwhile battery is operational and charging, but inverter decided not to give AC output till battery is 100% full after it had reached min DC cut off

I will try it, but this changes the priority to utilize battery over utility for AC out, which I am not in favor. My current setting is SUB. I am expecting the AC out to start feeding from Solar which has enough capacity before my battery reaches 100%. In this is specific case utility is not...

yes, that's considerably high, it may blow up some parts in your inverter In my case i was having 7 panels in series, 2 strings parallel, my inverter can handle 28amps and i was below this numbers. i wouldn't put 2 strings on this model of Growatt

I had a similar problem with Voltronic inverter, watts and volts on PV input was quickly and highly dropping for seconds during high load only, the solution advised by Voltronic is to add a capacitor of 400vdc 3.3µF at the PV input connectors on the inverter. It had resolved the problem up to...

Hello, In off-grid mode, my Voltronic Infinisolar V IV, after reaching a low DC cut off thorough SOC of 60%, the AC output will cut off as expected overnight, next day morning PV starts charging the battery while AC output from inverter is still off. The inverter will start providing the AC...

I purchased and installed Solar Assistant, it is pretty cool as described and it worth it. I am struggling with some glitches, is there support for the product? i am writing to info@solar-assistant.io but they are not responding. Is there any official support?

Yes, 4 in parallel, 5kw each, Voltronic LIO II 4810 lithium, connected to the 3 inverters.

Fluctuation is happening on all the 3 inverters, but there is a noticed pattern, before i installed the capacitor, fluctuation would start when load increases above 15A, while after the capacitors were installed, fluctuations started when load goes higher than 35A only, below this number no...

That's the DS of my panels I meant i am seeing 332v from PV on the LCD screen on the inverter on a sunny day before putting any load, during load it goes down to 270v

This is the related DS

The max PV input as per the inverter is 400v, i put 7 in series, each is 49.5voc, i am getting 332v at peak sunny hours without load, during load it goes down to 270v. Do you think it worth trying since it is way below the max?

What could be the solution? a different capacitor if not a different inverter?

yes and during the drops it will use the battery power to cover the load, when PV recovers then batteries will be charged back. batteries keep charging/discharging continuously.

We struggled for 3 weeks at least trying to troubleshoot the reason why watts on PV output fluctuates drastically during load. I have 3 Voltronic Infinisolar V IV hooked in parallel 28 Longi panels 545w inverter1, 7 in series inverter2, 7 in series interter3, 7 in series+7 in series During...

I am struggling with a strange case where PV input is fluctuating under load, if i bring the load down then PV input will be very stable. Cabling and size are as per standards, this problem is happening only when inverters are in parallel, if i switch off other inverters and keep only 1 then PV...
