When I turn on the inverter, I hear vibration type noise, and panel reads inverter over load, and it shuts off. When I crank the generator all electric stuff works fine, and no excessive current draws. When I turn on the inverter, the breaker in the electric outlet in the lavatory blows. When it blows I loose electricity on all out lets on the right side of the motor home. Using generator it doesn't blow Batteries are charged up.
