SOFAR PowerAll ESI 5K-T1 + BTS 5 kWh Smart energy storage system is a three-phase hybrid system consisting of a 5 kW inverter and two high-voltage LiFePO4 battery modules.

The set offers 5.12 kWh of total capacity and 4.75 kWh of usable capacity. The BTS 5K Smart modules feature integrated heating, which supports battery operation at low temperatures.

The system enables the storage of surplus energy from a photovoltaic installation, increases self-consumption and supports both on-grid and off-grid operation. The inverter features 3 MPPT trackers and switches to backup power for critical loads in less than 10 ms.

Benefits for the user:

An energy storage system makes it possible to use more of the energy generated by a photovoltaic installation, reduce the amount fed into the grid and increase self-consumption. The stored energy can be used in the evening, at night or during a power outage. The system helps reduce energy costs, increases independence from the grid and improves the comfort of using a PV installation.

Higher self-consumption of photovoltaic energy

The energy storage system stores surplus energy generated by the photovoltaic installation and makes it available when household demand is higher than current production. As a result, less energy is fed into the grid and more is used on site, increasing the profitability of the PV installation.
