Frequently Asked Questions
Are these batteries compatible with my existing solar inverter?
The batteries offer high compatibility via RS485, CAN, or RS232 protocols, supported by most major inverter brands such as SMA, Growatt, Solax, Victron, and Deye.
What is the expected lifespan of the battery system?
Lithium iron phosphate (LFP) batteries typically offer 6,000-8,000 charge cycles, which equates to approximately 10-15 years of daily use depending on conditions.
Do the batteries include safety protection features?
Yes, they are equipped with a comprehensive Battery Management System (BMS) providing overcharge, over-discharge, short-circuit, temperature, and overcurrent protection.
Can I monitor the battery performance remotely?
Yes, we provide a cloud-based monitoring platform via App and Web. You can track real-time status, charging/discharging metrics, and overall battery health.
How do I choose between grid-connected and off-grid systems?
Grid-connected is ideal for stable urban areas to save costs. Off-grid is for remote locations without grid coverage. For unstable grids, a hybrid system with off-grid switching is recommended.
What application scenarios do these products serve?
Integrated solar-storage-charging systems, peak-valley electricity arbitrage, emergency backup power supply, and low-temperature environments.
