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
