Verdict (specs only) Want the most stored energy for the money and a published cycle rating? AC180P (1440 Wh, 1800 W / 2700 W Power Lifting, 3500+ cycles to 80%, 35.27 lb). Want the lighter box, faster full charge and a lower price? DELTA 3 Classic (1024 Wh, 1800 W / 3600 W surge, 26.7 lb, full in about 60 min). Inverter and solar are a tie on paper. We did not test either unit.
