SOLE 5000

Low voltage energy storage system

SOLE 5000

The SOLE 5000 home Energy Storage System (ESS) is a lithium iron phosphate battery (LiFePo4) based system with a nominal capacity of 5.12 KWh at 51.2 VDC / 100Ah.

It is suitable for small and medium-sized houses, and up to 16 modules can be connected in parallel to increase the capacity to 81.9 KWh. This ESS can be connected to the Internet of Things (IoT) communication module and can be remotely updated to work with various low-voltage single-phase and three-phase inverters, making it suitable for multiple application scenarios. This ESS can be used to store excess solar energy or cheap night-time energy and release it as needed, such as during power outages or at night.
