Description

The FoxESS Hybrid Off-Grid/Grid-Tie Home Energy Storage System Kit is a turnkey solution for home energy, with a 5.7kW output hybrid inverter, 11.92kWh FoxESS stackable high voltage storage with 3 battery modules, and a FoxESS Smart Hub for easy monitoring and having an ability to seamlessly switch to backup power when power outages

This energy storage system is designed for households that have newly installed solar systems, aiming to achieve self-consumption of home electricity, lower electricity bills, and improve the return on investment efficiency of the solar system. It also enhances the stability of your home power supply.
System Notable Features:

  • It greatly reduces the reliance on grid energy for household electricity by generating your renewable energy, allowing for self-consumption, and ensuring a stable energy supply for your home.

  •  Self-consumption means that the storage system can store the excess electricity generated by the rooftop solar panels during the day that cannot be immediately consumed, in the energy storage system. This stored energy can then be utilized during the evening when electricity demand and prices are both at peak rates. This home energy battery storage system maximizes the reduction, and even elimination, of your electricity bills, achieving self-consumption. It significantly enhances the utilization efficiency and returns on investment of the solar power system, especially in areas implementing Time of Use(TOU) electricity pricing policies. For example, in California's new solar energy policy NEM3.0, if there is no energy storage system, selling excess solar electricity to the grid during the day would not exceed 8 cents per kilowatt-hour, but when the solar power system does not generate electricity at night and electricity needs to be drawn from the grid, the price of electricity would not be lower than 30 cents per kilowatt-hour.

  • In situations of unstable grid power or power outages, the system can intelligently switch to Off-grid mode, supplying power to your household appliances and loads through the energy storage system, enabling your home to have an independent energy supply.

FoxESS H1-5.7-US 5.7kW Split-Phase Hybrid Inverter
The H1-5.7-US is a split-phase hybrid inverter that works with a rechargeable high-voltage energy battery and powers your home load. Its Innovation, quality, and high performance make it extremely suitable for residential energy storage systems. 

The FoxESS H1-5.7-US inverter has 2 MPP trackers with 3 strings (2 strings for one tracker, and 1 string for another tracker)that can be connected, making it transformerless and particularly efficient. The CEC efficiency is 97.0% and the max efficiency is up to 97.6%. This is important when the PV system consists of areas with different strengths, such as an east-west orientation.

In the event of a power outage, this hybrid inverter with built-in emergency power capability continues to supply one phase with a switch-over time of 20ms and a power output of 5700W. 
Key Features

  • Easy installation, flexible configuration, plug-and-play set-up
  • Work with high-voltage batteries for maximum round-trip efficiency
  • IP65-rated, suitable for outdoor installation
