New Energy Storage System for solar systems with LiFePO4 batteries

PHIHONG TECHNOLOGY CO., LTD.

PHIHONG 3500W / 230V Energy Storage System

An energy storage solution designed to work with photovoltaic systems, especially where there is a large difference in usage between day and night, for places with unstable grids or for emergency needs.

Designed for residential or small commercial use.

The 3.5kW Energy Storage System consists of rechargeable batteries (up to 3 banks of 2kW batteries each), an AC/DC charger, and a DC/AC inverter that generates a Pure Sinusoidal AC Wave to power the loads; This product functions as a simple UPS.

Features

• AC output overload, over current, over voltage protection
• AC input over voltage, under voltage, over current protection
• Over temperature protection
• SAFE & expandable
• Convenient and safe high capacity energy storage for residential and small business needs
• Working with solar inverter
• Automatic switch between Backup and Bypass modes
• Automatic charge from PV panel during the day and charge from utility power during the night
• Advanced LiFePO4 (lithium iron phosphate) battery for high power, high cycle and safe home use
• Very low self-discharge rate for the battery
• Battery expandable from 2kWh to 12kWh (1~6 units)
• Automatic AC frequency detection
• Built-in relay bank to switch between grid, PV panel, and load
• Simple UPS function
• Communication interface: RS-485 / PLC

3.5kW / 230V Energy Storage System

Operating Modes

When solar light is adequate, the batteries are not fully charged, and the unit is "ON" and powered by the grid, the batteries are recharged (charging mode) and at the same time the grid powers the loads (bypass mode).

When solar light is adequate, the batteries are fully charged
