We’ve been getting a lot of requests lately for larger residential storage, and the 15kWh capasity on this one is good fit for homes pulling 30-40 kWh daily in winter.
It uses LiFePO4 chemistry, so cycle life is rated at 6000 cycles give or take, and it operates from -30°C all way to 60°C — which actually matters for garages here in summer when temps spike.
The weight is 176 kg so you’ll need two people and a dolly to position it, but the natural air cooling means no fans or pumps to fail over time, and the IP20 rating is fine indoors but don’t mount it outside.
Communication ports are CAN and RS485, usually our company can customize if needed, but confirm lead time because the firmware batch varies (check with sales on stock).
When you order it you get the 300AH unit with an LCD indicator on the front — it shows voltge and SOC at a glance, plus we include a COA from teh supplier showing typical cell grade as premium A-grade.
The over-charge, short-circuit, and temp protections are built-in, so you won’t need an external BMS for basic setups, but for commercial builds you’ll still want a separate breaker.
Our standard MOQ is 10 units per model, but we can negotiate lower quantities for initial trial orders. Just let us know your needs.
Yes, we supply CE, UN38.3, and MSDS documentation with every shipment. Third-party test reports for capacity and cycle life are also available on request.
Absolutely. The communication ports are customizable to match common inverter protocols like Victron, SMA, or Deye. Just share your inverter model, and we'll adjust the BMS firmware accordingly.
Store it in a cool, dry place between -20°C and 65°C with humidity below 85% RH. For best longevity, keep the charge at about 50% and recharge every 6 months.
The LCD shows real-time data like voltage, current, state of charge, and any fault codes. It's straightforward and helps you monitor the battery's health at a glance.
