I have 2x Multiplus 2's working in parallel to supply a single phase house. I have a PV inverter connected to the output and it is offgrid. The system for the most part is great and works a treat. But lately has been behaving strangely[could be hot weather]. During charging, when it reaches about 90% or has been in absorption for about an hour, it disables the inverter by going right up to 52hz. But it doesn't tell me why. Then after random amounts of time, comes down again. I've got no idea why. There are no errors in the ccgx. I've even tried pouring through the logs in /data/log. But there are no clues there that I can find. Refer to the pick, it always seems to happen about 90% SOC.
