Here is my configuration:
four 175W HQST panels in series (Open-Circuit Voltage (Voc): 24.3V, Optimum Operating Current (Imp), 8.62A), VE MPPT 150/45TR SCC, four 12V LiFePO4 (105Ah) in parallel, Giandel 12V 2200W inverter.
I have this problem that the inverter is constantly tripping on over voltage (16V or higher). The VE 150/45 surges over 16V when cloud cover opens quickly, and the draw on the inverter drops as well. I have set up a "Battery Preset" customized for the batteries and it works fantastic. The inverter manual suggests to not use the inverter if overvoltage shut downs occur. That defeats the purpose of having solar. Any ideas?
Is there any way to limit the power spikes/surges on the controller?
