November 27, 20232 yr My Fivestar 8.5kw Inverter is showing a fault code 21. I do not have a manual, and the installer is no longer around. Can anyone tell me what this means ?

But I can find no mention of fault code 21 in the first two MAX manuals I looked at, and even in the first MAX firmware that I found where I had recorded the fault code calls, none were for fault code 21. So I'm afraid that you will have to find an actual Fivestar manual for your model.
November 28, 20232 yr Author Thank you. It shows on the front 8.5KVA 6.5KW 100A MPPT German Technology. I had solar added and that is when the code appeared.
December 1, 20232 yr This is a manual someone on the forum sent me before, 21 might be a communication issue with a lithium battery. Fivestar Manual - another type - same setttings.pdf
