I’m looking at a setup for my new house in which the meter feeds into a service entrance rated 200 amp automatic transfer switch designed for use with a generator but with solar on the other side rather than a generator. The ATS would sit between the mains inputs and the main panel so this is...

I have a customer that bought these batteries and I am having a very hard time getting reliable information about the specs on this battery. The information on Amazon is conflicting and I have had little to no help getting the specs for these batteries for the Victron Smart Shunt settings. I...

I watched that video. I'm pretty sure the output was right on the money.

You're incorrect. You're being stubborn and not reading the whole thread. And GROWATT (The actual company) Said it IS a software bug. And it was solved. Why do you not want to listen?

This was already solved. Between me, signature solar and growatt they determined it to be a software bug. As I reported the voltage never dropped below spec. Even when the voltage and current were strong in full sun the problem occurred. The fix was to change the panel configuration...

" It's funny that this would be the only example of this occurring though" This isn't the only example of this happening. I run the largest Growatt group on Facebook. On that group there are many examples of this happening and no one found a fix until I figured this out. As I stated in...

I had a monitor on it continuously for two weeks. The lowest recorded voltage was 36 volts on a few brief occasions but typically it remained at an average of 45 volts. The PV input limit is between 30 volts to 115 volts. I also tested the voltage at the PV inputs on a very dark rainy day...

I was able to bring this to the attention of both Signature Solar and Growatt. And Since Signature Solar works directly with Growatt hopefully they will be able to fix this sooner than later. But it was a tough solve but I do feel accomplished for figuring it out. lol

Are you trying to say there was never a problem? Both Signature Solar and Growatt agree that there is an issue here. The PV input voltage range is 30 volts to 115 volts. The incoming voltage from the array was between 36 volts to 49 volts. The voltage from the array was within the...

UPDATE! PROBLEM SOLVED I solved this problem. I didn't have any luck with signature solar or with Growatt USA but after a lot testing this is what I found out. Bottom line is that the MPPT voltage limit is 30 - 115 volts. The incoming voltage with the three 395 watts panels in parallel is...

Ok, UPDATE TIME! So signature solar told me that they think the Growatt SPF 3000 is defective. However, since I had another SPF 3000 on the way already for another install I decided to wait to send it back and do a bench test of the new unit with all the factory setting In place. So I decided...

I have a second Growatt SPF 3000 so I am going to put one of my extra 400 watt panels on it and a 1500 watt heater as a load and a 100ah LiFePO4 battery I have and see if I get the same error with the factory settings. If it works then I will configure it with the same settings I have on the...

There is 1185 watts. It is (3) 385 watt panels and they are run in parallel. The client camps in a lot of shade areas so needed the protections of the 3P configuration. Total array specs. 3P: 49.6 volts at 29.7 amps

I am beginning to believe that the inverter is defective as well. Fortunately, I have another SPF 3000 for another upcoming project coming up so if it is bad I can just swap it out really quickly. But I hope it is just something simple that I am missing.

Yes, if you turn off the power switch at the bottom of the inverter it will shut off the Inverter portion of the unit and the MPPT charge controller will still continue to function and charge the battery. I currently am having an issue with this. I have posted this in another thread...
