7KW Hybrid Off Grid Solar Power System (PWM Control)

Introduction

GTPL series solar system consist of the solar panels,low-frequency inverter&controller integrated ,battery ,cables and PV bracket.The solar inverter adopted the most advanced technology and the latest net-work communication technology, giving a perfect power solution for your restrict requirements. It is small, light weight and high efficiency. In inverter state, it is almost no noise. Inverter integrated with PWM technology, and its  voltage is fully sine wave output, suitable for capacitive load, inductive load and nonlinear mixed load. Also, its efficiency is 10% higher than that of other inverters; protection functions are perfect, such as overload, short circuit, battery voltage over-high or over-low, these will not cause your machine breakdown. By RS232 communication port, the inverter and power status could be monitored from the connected PC, to understand the working data, setting invreter off, monitoring the working parameters, and to expand functionality for remote network monitoring (via SNMP ADAPTER). It can meet a variety of solar power systems.
