Off-Grid Solar Inverter 3KW ~ 8KW
Off-grid Hybrid Solar Inverter GF series products are on the basis of green energy use and equipment electricity need for remote area, combing the electricity characteristics of household appliances, communication station equipment and computer peripheral equipment. They have the function of energy conservation and environment protection. They adopt MCU control technique, having various kinds of function such as multi-setting mode, MPPT control, voltage stabilization on line, short-circuit protection, inverter frequency adaptive, output overload, battery charging management, monitoring etc. With display of LCD and LED, all the parameters and running status could be visible. Intelligent monitor is available via RS232 & USB connecting with PC, while remote control via RS485 &SNMP. Off-grid Hybrid Solar Inverter GF series products are the ideal power supply delivered with excellent performance, high stability, high reliability and high practical applicability.
