Well after making the changes I hooked up a 1500w heater to my 2000w inverter which works fine. Then I turned on the Voltstart, which starts the engine if the voltage of the house battery gets too low and the battery is charged from the High amp alternator. I just found out that it puts out 280Amps, the BMS is 150A, so after a minuet or so it shuts down. After another minute it restarts and so on. So what to do. What do you think? any solutions other than a 200A BMS?
