Brief introduction

The integrated energy storage system is a combination of inverter and battery, which is mainly used in household energy storage system as picture F2-2.

The combination of a PV, battery power grid, and electricity meter forms a household storage system. With this system, your family could achieve energy independent. Take your energy future into your own hands and reduce your energy costs to a minimum. The ESS system can also be used as Emergency power supply.

Inverter Technical Specification

Battery Technical specification


To prevent the load leakage affecting the inverter, it is recommended to connect an isolation transformer outside the load output port. Isolation transformer secondary N line connected to PE.

Working Mode

According to the power grid conditions, the working state of the system can be switched automatically. There are four working modes: Storage mode, Load mode, peak cutting and valley filling mode, and off grid emergency mode.

Storage Mode

At the storage mode, the system will charge the battery prior until it is fully charged. And the stored energy can be used for emergency application.

Load Mode

Under load mode, the system will ensure the power of consumption load first to reduce the power taken from public power grid.

Peak Cutting and Valley Filling

The customer can freely set the charge and discharge time of the battery through the upper host PC of the inverter. Set the system to load mode in peak hours. And switch to storage mode at the low-price period. In this way, the difference of electricity price in peak and valley period can be reasonably utilized to bring benefits to your family. As shown in the following picture.

Off Grid Emergency

When the public power grid is cut off, the system can be used as a backup power supply.
