Low Frequency Power Inverter

EP3000 LV Series Low Frequency Pure Sine Wave Inverter (1-4KW)

EP3000 LV series is very economical pure sine wave inverter, special in north & south america market, and AC charger from 35A to 70A .Solar /AC priority configurable . When solar priority , in case its charge current lower than inverter’s charger from AC , AC will supplement to charge the batteries ,to optimize charging. With low frequency transformer ,it enable the inverter to operate with all kinds of home appliances.
