Industrial & CommercialAC BlockUpdated Aug 27, 2026

Tesvolt TESVOLT FORTON is an LFP battery energy storage system for commercial and industrial use, with 92 kWh nominal energy and about a 1-hour duration. It is supplied as an AC block with 92 kW rated DC power and air cooling. It records 98.7% AC and 98.5% DC round-trip efficiency and weighs 1.4 tonnes (3,086 lb).

Use Cases

Use behind the meter is consistent with the specifications of TESVOLT FORTON. By energy capacity, it belongs to the commercial and industrial class, and it connects at 400 V.

Capabilities

Its AC block includes the inverter, which points to TESVOLT FORTON for renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. The listed configurations include 1 h as the minimum. That configuration points to peak shaving, discharging into the hours of highest demand.

Plant Round-Trip Efficiency at the Point of Interconnection

Both measured at the grid connection point. The plant's own power use is already included in the losses.

The calculator estimates the full "plant" round-trip efficiency (RTE) at the point of interconnection. Some values are pre-blocked depending on information on a particular ESS. The rows that are marked "each way" are one-way efficiencies; they are applied on charge and again on discharge. We then square them. To enter a bundled PCS efficiency value, use its rated-power value, not peak. If the PCS skid already includes the LV/MV transformer, set Transformer LV/MV to 100 % so those losses are not counted twice.
