Description

Sunjoy energy 32kwh lithium battery.png

High-Capacity 32kWh Home Energy Storage Solution

The Sunjoy Energy SJ-HE-32K-48M is a 48V 32kWh low-voltage lithium battery designed for residential energy storage systems, solar power storage, backup power and hybrid solar applications.

With its large 32kWh capacity, the battery can store excess solar energy during the daytime and supply power to household loads when solar generation is insufficient or during grid outages.

It is an ideal solution for homeowners, solar installers, distributors and energy storage system integrators looking for a reliable and scalable 32kWh home battery storage system.

EVE MB56 628Ah LiFePO4 Cells

The battery pack is built using EVE MB56 628Ah cells, configured with 16 cells in parallel to provide high capacity and stable energy storage performance.

The use of high-quality LiFePO4 battery technology provides excellent safety characteristics, long service life and reliable performance for daily residential energy storage applications.

Up to 8,000+ Cycle Life

The SJ-HE-32K-48M is designed for long-term energy storage applications with a cycle life of up to 8,000+ cycles under specified operating conditions.

This makes it suitable for frequent daily charge and discharge applications, including solar self-consumption, peak shaving and backup power.

Intelligent PACE BMS

The battery integrates a PACE intelligent Battery Management System (BMS) with up to 200A continuous over-current capability.

The intelligent BMS continuously monitors and manages key battery parameters, helping provide protection and stable operation during charging and discharging.

The BMS also supports multiple communication protocols, enabling communication with different types of solar and hybrid inverters.

Compatible with 99%+ of Mainstream Inverters

The SJ-HE-32K-48M is designed for broad inverter compatibility.

Through multiple communication protocols, the battery can communicate with and operate with 99%+ of mainstream inverter brands, subject to inverter model, communication protocol and system configuration.

This makes it easier for installers and distributors to integrate the battery into existing solar energy storage systems.

Up to 15 Batteries in Parallel

The system supports up to 15 batteries connected in parallel, providing flexible capacity expansion for larger residential energy storage applications.

This scalable architecture allows users to start with a suitable battery capacity and expand the system as their electricity demand increases.

IP54 Protection with IP65 Option

The standard battery enclosure provides IP54 protection for residential energy storage applications.

For customers requiring enhanced outdoor protection, Sunjoy Energy can provide a higher protection level such as IP65, subject to configuration and customization requirements.

3.2-Inch Touchscreen

A built-in 3.2-inch touchscreen display provides a convenient interface for viewing key battery operating information and system status.

The integrated display makes daily system monitoring easier for homeowners, installers and maintenance personnel.

5-Year Standard Warranty

Sunjoy Energy provides a standard 5-year after-sales warranty for the SJ-HE-32K-48M.

For distributors, installers and project customers requiring longer-term service support, a 10-year after-sales option can also be provided according to project requirements.
