Frequently Asked Questions
Q1: How do you ensure the quality of the battery cells?
A: We use only freshly produced LiFePO4 cells. Every battery undergoes a rigorous cycle test, including full charge and discharge, to ensure high performance and consistency before delivery.
Q2: Are these batteries compatible with my current inverter?
A: Our systems are compatible with most popular inverter brands (Victron, SMA, Deye, Growatt, etc.) via CAN or RS485 communication. We can also update our system if provided with specific communication protocols.
Q3: Is the LiFePO4 chemistry safe for home use?
A: Yes, LiFePO4 offers higher thermal stability compared to other lithium types. They do not catch fire or explode during overcharging or short circuits, and are free from cobalt and cadmium.
Q4: What is the expected lifespan of the battery?
A: Under standard 25°C conditions and 0.5C charge-discharge rates, the battery cycle life exceeds 6,000 cycles, providing long-term reliability for over 10 years.
Q5: Do you offer customization for large projects (OEM/ODM)?
A: Yes, we provide full OEM/ODM services including hardware, software, and structural design. This typically requires a minimum purchase volume and covers necessary certification and mold costs.
Q6: What technical support is available if I have issues?
A: We offer remote technical support using advanced AR technology (Zoho Lens) to diagnose and guide repairs. Authorized local dealers also provide professional on-site support.
