Low Frequency Solar Inverter

PV3000 PK Series Low Frequency Off Grid Solar Inverter (1-6KW)

PV3000 PK series is a very economical pure sine wave inverter with 50A PWM solar charger controller. And AC charge current range is from 35A to 70A. PV/AC priority adjustable. When PV is priority, if its charging current is lower than that of AC, the AC will supplement the extra power and charge the batteries simultaneously. With low frequency pure copper transformer, the inverter is suitable for all kinds of home appliances.
