Hi, I have searched options on how to do this but none of the seem to fit what I’m trying to achieve.
Multiplus II 12/3000
Cerbo GX & touch screen
Lynx smart shunt and distributor
2x 220Ah AGM batteries
These are installed within a box trailer which we use for racing karts, basically transport and accommodation for when we camp at the track and somewhere to cook & eat.
I have some 230v outlets plus DC Distribution serving lights, compressor, 12v outlets etc. AC inlet rated at 16A for connecting either grid or generator dependant on what’s available.
Sometimes we will have a grid hookup available, other times we will have to use a generator ideally via auto start assistant so need to have flexibility on power source.
I’m wanting to be able to use either a physical switch via one of the digital inputs or a switch on the touchscreen to swap between grid and generator modes.
Mode 1 - If grid is available we plug in and select grid on the switch, the MP then passes AC through and charges the batteries, with AC current limited to 16A.
Mode 2 - no grid connection is available then we plug in the generator, the MP then runs inverter from batteries and auto starts the generator when required via generator assistant - eg low soc, high load etc. As the generator is only rated at 3kva then the AC current is limited to 13A.
I know there is an assistant to switch the current limits via a digital input but I can’t find anything that will change the priorities between AC and DC sources.
Any help or ideas would be greatly appreciated
