Project Description

5kwh solar system with pv and MPPT inverter for home application

1. Overview

The 5kwh solar system with pv, LiFePO4 battery and MPPT inverter is specially developed for home application, this system mainly consists of PV modules, MPPT inverter, LiFePO4 battery bank. Can work with or without battery, if “solar first” is selected as output source priority and battery is not connected, solar energy and the utility will provide the loads. It also can operate as a off-grid inverter to provide continuous power even without the grid. It is a perfect power solution for home application. Specically for some places have large different electric price for day and night.
