charlestee zvobgo Posted August 14, 2021 Share Posted August 14, 2021 Good day, how are you? We are experiencing a challenge with one of our installations consisting of a 5kva Growatt SPF-5000 and Pylontech US3000 lithium-ion battery, the inverter is failing to bring in the utility to charge the battery when its voltage drops. May you kindly assist us on how we may rectify this... Quote Link to comment Share on other sites More sharing options...
deanfaraday Posted August 15, 2021 Share Posted August 15, 2021 Hi, we had a similar issue and it was rectified by updating to the latest firmware. This can be obtained from Growatt directly. Quote Link to comment Share on other sites More sharing options...
