I have bought a Multiplus 48/500 to boost my charging on my batteries on cloudy days but its only charging 1a from my generator.
Lots of possibilities. What charge stage is it showing it is in at 1A? Whats the battery SOC at this point? Did you program the MP?
the battery state of charge is 40%. But i have not got communication to the battery to the MP? I did set the maximum charge voltage in MP and it no where near that. I’m sure it was say Bulk charging
