ChenXin 5kWh Home Battery — Reliable Backup Power for Every Household
The ChenXin 5kWh Home Battery is our entry-level energy storage system, purpose-built for homeowners who want to slash electricity bills and keep essential appliances running during outages — without paying premium Western-brand prices. At 5.12kWh of usable LiFePO4 capacity, it powers lights, Wi-Fi, a refrigerator, fans and mobile devices for 8–12 hours through a typical blackout.
Unlike cheap lead-acid alternatives, every ChenXin battery uses Grade-A LiFePO4 cells rated for 6,000+ charge cycles — that's 15+ years of daily use with zero thermal-runaway risk. The built-in smart BMS handles cell balancing, over-current and over-temperature protection automatically, while the slim wall-mount design (just 170mm deep) installs neatly in a garage or utility room.
It works with all major hybrid inverters and solar setups, ships to 50+ countries with CE/FCC certification, and is backed by a 10-year warranty. Homeowners in outage-prone regions use it for backup; tariff-conscious households use it for solar self-consumption and peak-shaving. See how it performs during frequent power outages →
