Got Questions? We've Got Answers.
Q: What battery chemistry do you use?
We use LiFePO4 (Lithium Iron Phosphate) chemistry for all our battery products. It offers the highest safety, longest cycle life (6000+ cycles), and excellent thermal stability compared to other lithium chemistries.
Q: Can your battery work with Victron inverters?
Yes. Our batteries are compatible with mainstream inverter brands including Victron, Huawei, Deye, Growatt, SMA, Goodwe and more. We support CAN bus and RS485 communication protocols.
Q: Do you support OEM/ODM?
Yes, we provide full OEM/ODM services including custom logo, packaging, labels, firmware branding, and even custom product design based on your specifications. MOQ applies.
Q: What's your MOQ (Minimum Order Quantity)?
MOQ varies by product. For standard battery modules, MOQ is typically 10 units. For complete BESS systems, MOQ is 1 set. For OEM orders, MOQ is negotiable based on customization level.
Q: What's the cycle life of your batteries?
Our LiFePO4 batteries are rated for 6000+ cycles at 80% DoD (Depth of Discharge), which translates to 10-15 years of service life under normal operating conditions. We provide a 10-year warranty.
Q: Can batteries be connected in parallel?
Yes. Our battery systems support parallel connection for capacity expansion. Up to 15 units can be connected in parallel for residential systems, and rack-mounted systems can scale up to 600kWh for commercial applications.
Q: Which inverter brands are compatible?
Our products are compatible with Victron, Huawei, Deye, Growatt, SMA, Goodwe, Solis, Luxpower and many other mainstream inverter brands. We can provide a full compatibility list upon request.
Q: What's the warranty policy?
Solar panels come with a 30-year linear power warranty. Batteries come with a 10-year warranty. Inverters come with a 5-year warranty. Extended warranty options are available for bulk orders.
