These are awesome batteries we have been supplying and installing these batteries from mid 2020. Never had any major issues except for a quick firmware update. These batteries work perfectly with 5kw inverters. Attached is a video of Luxpower installation with the 3.68 battery- This specific customer has confirmed that she uses her aircon during load shedding and there were no alarms or any issues with the battery. A 2nd customer is using 3 x 5 kw luxpower inverters in parallel (3 phase power) with a 3..68 Greenrich. His average consumption during loading shedding is between 800w to 1.5kw and his battery survives the loadshedding without any complaints.
