I have a Multiplus II 48 3000 installed on my boat with LiFePO battery bank. When first set up, I could get 1900 watts of charging output. Now I cannot get more than 1300 from 30a shore power or 3000 watt inverter generator. MPII setting at 35A charge max. DVCC not being used. Any ideas on why my output seems to be limited to 24A/1300W?
24A would be the default 75% limit which suggests the settings may have reverted to default possibly after a firmware upgrade?
Which setting has defaulted to 75%? I have verified the charging max set at 35A while output still does not exceed about 24A. Is there a multiplier or limiter somewhere?
As I think about the chain of events,... the 1900 watts (about 35A DC) was achieved with "out of the box" MP II configuration. I have since configured for my LIFePO bank. The charging output has been limited since then. But I don't see what setting would need to change to restore full output.
Are you running the quite fan assistant?
Thanks for the help. Un-ticked the Weak AC box in configuration settings and charger output returned to 35A.
