What would cause the12Volt LED lighting in my RV to surge while operating 1Air conditioner while inverting power? While on shore power/generator the problem does not exist.
I am running 2 12v multiplus with 600ah of Battleborn batteries to power my entire RV.
I have checked all 12v connections to the inverters.
An air conditioner is quite a heavy load that ends up on the battery. The air conditioner will have a very large startup current which will cause the battery Voltage to sag, there will be several hundred Amps drawn from the battery at that moment. So it's not surprising that your lighting suffers from the Voltage sag.
