Frequently Asked Questions

What battery cells are used in the solar battery systems?
We utilize brand new A+ grade LiFePO4 prismatic cells from leading manufacturers (such as Gotion or BYD). These premium cells achieve more than 6000 cycles at 25°C under 0.5C conditions.
Which hybrid inverters are compatible with these batteries?
Our built-in Battery Management System (BMS) features communication protocols compatible with major three-phase and low-voltage hybrid inverters on the market, including Deye, Growatt, Sofarsolar, Goodwe, Luxpower, and Megarevo.
Why should we choose a high-voltage battery system?
High-voltage batteries operate with three-phase hybrid inverters to meet higher power output demands. A high-voltage system allows for a greater overall kW output, perfect for managing larger household or commercial loads.
What is the standard warranty period for the products?
The systems come with a 10-year warranty against defects in materials and workmanship, provided operation guidelines are followed. Under regular operating conditions, the batteries retain at least 80% of their usable power after the warranty duration.
Do you support OEM and ODM services?
Yes, we are a specialized LFP battery energy storage system solution provider. We can select, configure, and customize battery systems (including voltages, capacities, and matching protocols) according to your application and specific inverter specifications.
How are after-sales issues resolved, and what support is available?
Our engineering team resolves software issues remotely using firmware updates. For hardware issues, we supply replacement parts immediately. We also provide full installation video guides, manuals, and physical replacement units directly from our European regional warehouses to avoid delivery delays.
