The Sofar ESI T1 Series Hybrid Three-Phase Inverter is a unit that, together with the Sofar BTS 5K battery pack, forms a modern, safe, and highly efficient electricity storage system PowerAll, designed not only for residential users but also for small-scale industries.

The PowerAll Energy Bank is a comprehensive home energy storage system with an integrated hybrid inverter. The system includes one three-phase hybrid inverter from the T1 series and from 1 to 6 lithium-ion batteries, allowing energy storage from 5 - 30 kWh. It is designed for households and storing electricity generated by PV installations or drawn from the power grid. By connecting up to 6 units, a capacity of up to 180 kWh can be achieved. The PowerAll system can operate in both on-grid and off-grid modes, providing full control over power export. It also directly contributes to effectively increasing self-consumption.

When working with PV modules, the device automatically stores excess solar energy during the day for later use, either during the day or at night. An additional advantage is the ability to set charging and discharging times when using the power grid, which is particularly beneficial for consumers on time-of-use tariffs. This allows them to pre-charge batteries when electricity prices are low and save energy when prices are high.

Key features of the PowerAll energy storage system:

• Modular and integrated AC-coupled energy storage
• Built-in battery management unit enhances battery capacity
• Flexible battery capacity expansion from 1 to 6 BTS 5K battery modules and up to 6 full units - from 5 - 180 kWh
• Easy system operation with a single button
• Maximum battery energy with package optimisation
• Max. photovoltaic input current: 20 A, suitable for high-current/bifacial modules
• Switching time to critical loads below 10 ms
• The battery side is fully electrically isolated, ensuring greater system safety
