Hi guys, I've done a few installs and have only 1, out of several installations issue.
Long story short the system was working perfectly fine until the client started doing ironing on the system. The battery got drawn down and was struggling gain charge. We managed to source a li-ion charger and the battery shows full on charge. However connecting it back onto the system we getting error 19(battery disconnect) on the inverter. We've decided to take the battery in for a warranty check. Is there anything else I can check to ensure the system is still good. This was my very first growatt installation.
