Hi, we have a Growatt 8kw grid tie inverter. It has been working fine for a few years now, other than a few ISO faults on the panel strings which are repaired. It has recently started going into standby for no apparent reason. No faults show, all strings are within 10 volts of each other and...

Turli Batteries. 6 200ah batteries, 5 months old. One reaches rated capacity. This one stopped working, see for yourself.

Hi, I've been having issues with some server rack batteries I bought, 200ah 48v. One of them was working Ok, then all of a sudden it started showing wildly mismatched cells and shut down. BMS is fried. I opened it and tried to disassemble but many of the cells were swollen and showed signs of...

I have some Turli 200ah server rack batteries. I need to remove the busbars and BMS connections to top balance some of them. The BMS is in the front compartment and I can't reach the plugs so I have to remove the + and - connections to the BMS first, then the connections to the cells. The mfg...

I have a bank of 6 200ah Lifepo4 batteries. In 2 of them I notice that they shut off prematurely, one at 52.5v the other at 50.9v. The rest of the batteries go down to my 47v switchback to utility with no problems and all cells closely matching their voltages. I see that one cell in each of the...

Hi, I have 6 Turli LifePo4 batteries that have been working perfect for about 4 months. While we were away there was a power failure lasting 3 days and at the same time heavy rain for 1 day and heavy clouds for 3 more, so the inverter shut down at my set low voltage point at 46v. When the sun...

Hi, My Growatt 8kw grid tie inverter has stopped working. It had ISO faults which I've corrected but it also shows an error 18, relay needs replacement. It tests normal voltage input to the terminals for pv but inside it has no voltage at any of the connections. I noticed on the board that...

I'm working on one of our Growatt grid tie systems in The Philippines. After the first typhoon of the season it started showing ISO faults and then a relay fault and shut down. I started with faults ranging from 150-300v on both ends of each string, so I know there are multiples on each string...

Hi, I have a 12kw Growatt DVM Split Phase inverter we installed a few months ago. Since first connected it has periodically showed a "Fan Lock" fault and shuts down momentarily. After that it started to show "Low Battery", didn't automatically switch back to utility and shut down for that reason...

I have an older 12kw inverter that operates on 96VDC/230VAC that powers our deep well pump and our water pressurization system. It uses gel batteries right now that I expect their end of life to be within the next year. But I have an opportunity to buy 12 new prebuilt 48v LifePo4 200ah rack...

I need to replace my Aims 10kw off grid inverter (I'm sick of it not working correctly) with another 48v 10-12kw off grid inverter. Most all of them except another Aims (NEVER AGAIN) or ones made by the same company that makes those, or Chinese brands I never heard of all seem to have built in...

Hi Everyone! I have a 10kw Aims off grid inverter. When I first installed it May 2020 it wouldn't load over 40% and would shut off with an overload alarm, on it's control screen the AC voltages had been reading about 20-50 volts below what was actually coming in from the utility, tested at the...

Hi, We are in The Philippines but use the same type split phase electric grid as at home (US). We have an Aims 10kw off grid inverter that is powered by separate charge controllers which produce about 14kw. It is set up to clip the excess when it's sunny and in the middle of the day so that when...

I'm building a 48 volt, 1120ah battery system with 64, 280ah LifePo4 batteries. I have 4, 60 amp charge controllers plus my inverter can charge 100amps, although I keep it set to about 20 amps so the solar will do most of the work. The inverter is an Ames 10k pure sine wave inverter. I seldom...

Has anyone actually set up one of these Elgris Zero Export Controllers? I have one but cant figure out how to get it to talk to my Growatt inverter, I’ve been told by others that have them and sales info that it communicates if I get an antenna for it but the company says it needs a direct wire...

We use the same electric system as the US with two 110 lines and a ground/neutral. We are not allowed to sell power back to the grid without huge upfront costs and then the payback is tiny, never cost recoverable. I have a Growatt 8000-US, designed for our type system, grid tie inverter that we...
