I installed a Magnum 2000 watt pure sine wave inverter/charger about 3 years ago, It has worked very well for us, we have never tried or needed to run a space heater on it and our stove uses gas the microwave, tv, etc work fine off of it. We bought the battery monitoring system which has worked fine and gives lots of information on the system. good luck! Steve Willett Monk 36, Gumbo Thibodaux, Louisiana
