This 48v (51.2V) 10KWh 200Ah LiFePO4 lithium battery solar energy storage system designed for house owner residential usage. 48v lithium battery 200ah energy is normally big enough capacity for a small house solar energy storage. With Coremax 51.2v 200Ah 10kwh, you don’t have to parallal small 5kwh powerwall anymore.

Coremax 48v lithium battery 200ah designed by experienced engineers come directly from BYD. With rich experience and advanced techniques, it features stable and fashionable design, high energy, high power density, long service life, and easy installation and expansion, all of which reflect the real requirements of the end users and the strongest technical capability. Thanks to BYD prismatic large capacity cells and also BYD battery pack designer.

10kwh in production

Lithium iron phosphate batteries is a kind of environmentally friendly backup power system. We use LiFePo4 rather than NCM to avoid safety concerns by lowering the possibility of thermal runaway because of improper disposal and save the production cost as well. Compared with other products in the market now, LiFePo4 experiences a lower rate of capacity loss. With state-of-the-art power conversion and energy storage technologies, our 10kwh wall mount Energy Storage System (ESS) offers high-efficiency power conditioning capabilities for demand management, power dispatch, renewable energy smoothing, etc. Coremax 10kwh LiFePo4 powerwall can provide comprehensive energy storage for residential, commercial and utility applications. Our solar energy storage system is now cover racked installation, wall mounted installation. and more will coming soon.
