MUST EP3000 PLUS 2kW, 1-phase, 12V, pure sine wave inverter with integrated AC charger, from 35A to 70A. Features: EP3000 PLUS Low Frequency Power Inverter/Charger is economical pure sine wave inverter, with AC charger from 20A to 60A; Solar/AC priority is configurable, when setting solar priority, solar will charge batteries as first priority, and AC can also charge batteries when solar charger current is too lower . With pure copper transformer, it enables inverter to operate with all kinds of home appliances.
