Application
Designed for users with higher electricity demands, the 3.5KW ESS is a versatile energy solution that effortlessly powers whole-house backup for large residences, daily green energy self-consumption for villas, or independent power supply in off-grid areas. With a rated output of 3500W, it can simultaneously run multiple devices such as air conditioners, refrigerators, microwaves, lighting, and routers, ensuring uninterrupted daily life and business operations.
Featuring a modular stackable design, the battery capacity can be flexibly expanded from 25.6kWh to 76.8kWh, accommodating various energy consumption needs. During the day, photovoltaic power (with MPPT up to 4000W) prioritizes supply and storage, while the battery discharges at night or on cloudy days. For regions implementing time-of-use electricity pricing, the system can utilize low-cost nighttime grid power for AC charging (up to 100A) and discharge during peak hours, significantly reducing electricity expenses.
Equipped with an advanced BMS, it provides comprehensive protection against overcharge, over-discharge, overcurrent, and overtemperature, ensuring stable operation across a wide temperature range from -20℃ to 70℃. With an IP21 rating and compact design, it is ideal for indoor installation. The 3.5KW ESS delivers stable, economical, and clean energy, empowering users to achieve energy independence and embrace a low-carbon lifestyle.
