I put in a professional RV 3500 watt inverter also. It was free so it was worth doing. It is also installed with 2 gauge welding cable to my battery bank. It has 4 outlets, and i ran a number ten extension cord to an outlet above our sink to plug a coffee maker or toaster in. Also ran a second one to the TV area as that is the thing we use it for the most (nascar stuff at the race). It has saved me in a pinch when i needed to air up a tire or run an impact to change a tire. Mine has the inside power switch with battery level indicator which makes it nice. As all my lights are LED now I dont worry about plugging in the main cable. When i need to charge the generator gets started and all plugs get moved to the normal AC outlets.
