Smart Protection
Intelligent Battery Management System
The integrated smart BMS monitors and protects every cell in real time — maximising cycle life and ensuring safe operation across all installation environments.
Over-Discharge Protection
Disconnects the load before cells drop below the safe threshold, preserving cell chemistry and maintaining rated capacity over the full design life.
Short-Circuit Protection
Instantaneously interrupts the circuit on short-circuit detection, protecting the battery pack and any connected inverter or load equipment.
Temperature Monitoring
Continuous real-time temperature sensing across all cell groups, with automatic load reduction or shutdown when thermal limits are approached.
Cell Balancing
Active or passive balancing ensures all cells maintain equal state-of-charge, maximising usable capacity and extending overall pack service life.
CAN / RS485 Communication
Industry-standard protocols enable seamless integration with hybrid inverters, SCADA systems, and energy management software from all major brands.

FAQ
Frequently Asked Questions
Common questions from solar installers, importers, and OEM customers about the 15kWh LiFePO4 battery.
How long will a 15kWh LiFePO4 battery last?
A quality LiFePO4 battery can last more than 10–15 years under normal operating conditions and deliver over 6,000 charge/discharge cycles at 80% depth of discharge. LiFePO4 chemistry significantly outperforms standard lithium-ion in longevity and thermal stability.
Can a 15kWh battery power a house?
Yes. A 15kWh battery can provide several hours of backup power depending on household consumption. A typical home drawing 3–5 kW on essential loads (lighting, fridge, appliances) can run for 3–5 hours. When paired with solar panels, it can provide near-complete energy independence during daylight hours.
Is LiFePO4 better than standard lithium-ion for home storage?
Yes — for energy storage applications. LiFePO4 offers 6,000+ cycles versus 1,000–2,000 for standard Li-ion, superior thermal stability with no risk of thermal runaway, a longer design life of 10–15 years, and cobalt-free chemistry. It is the preferred chemistry for residential and commercial ESS globally.
Can the 15kWh battery be used with solar panels?
Yes. The battery is designed for solar storage and supports CAN and RS485 communication protocols, ensuring compatibility with most major hybrid and off-grid inverter brands. Please share your inverter model when requesting a quote so we can confirm compatibility.
Do you offer OEM and ODM for the 15kWh battery?
Yes. We offer full OEM/ODM services including private label branding, custom casing design (wall-mount, floor-standing, rack), custom voltage and capacity configurations, communication protocol customisation, and retail-ready packaging. Our engineering team supports complete ODM development for international brands and distributors.
What is the minimum order quantity and lead time?
We offer flexible MOQ — sample and trial batch orders are welcome for first-time buyers. Most production orders ship within 7–15 business days from our Longgang, Shenzhen factory. Contact us with your required quantity and destination for a specific MOQ, pricing, and delivery timeline.
