I'm running that same Inverter!. I have ( 4 ) Ampere Time 100Ah batteries being fed from 850 watts of solar on the roof of my Camper, with a total of 2Kw of Solar when parked.. All this feeding through 3 Victron 100/30 Solar Charge Controllers.. ( Click on my name and you'll see the progression of my system ) I'd love to move all my gear over to an E450 Ambo some day!!!!
