You must use an approved lithium recharging system to take advantage of the warranty. A standard automobile alternator is NOT a proper lithium battery recharging system.


These powerbanks are designed for 24 volt systems and are NOT compatible with high-voltage inverters (like SolarEdge, for example).

This 7.16 KWh 25.6V 280Ah LiFePO4 lithium battery solar energy storage system has the advantages of large capacity, high power, small self-discharge, and good temperature resistance. Because of its reasonable structure, it is easy to assemble and disassemble.

The energy storage system adopts the latest Home Energy Storage System (HESS) battery system. With rich experience and advanced techniques, it features 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.


It is a kind of environmentally friendly backup power system. We use phosphates rather than cobalt to avoid environmental 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, this kind of product experiences a lower rate of capacity loss. With state-of-the-art power conversion and energy storage technologies, our energy storage system (ESS) offers high-efficiency power conditioning capabilities for demand management, power dispatch, renewable energy smoothing, etc. Our ESS can provide comprehensive energy storage for residential, commercial and utility applications. Our Li-ion battery portfolio covers cells, 48V modules, cabinets (indoor/outdoor) and containers, which offer customers excellent scalability and adaptability to a wide variety of requirements.


When the temperature sensor detects a cold outside temperature, it will warm up the cells first before it allows the cells to be charged. Without the sensor, the cells cannot be charged under 23F (-5C) and discharged under -22F (-30C).
