Industrial & CommercialAC BlockUpdated Aug 28, 2026

Tesvolt IA-62.5kW/500kWh is an LFP battery energy storage system for commercial and industrial use. It is supplied as an AC block with 509 kWh nominal energy and 2, 4, 6 and 8 hour configurations. The unit uses air or liquid cooling, delivers 61 kW rated DC power, and contains 306 Ah prismatic cells.

Use Cases

Tesvolt IA-62.5kW/500kWh has energy capacity in the commercial and industrial class. It connects at 400 V and is certified to low-voltage grid connection rules (EN50549-1). Together these specifications indicate use behind the meter, on the customer's side of the utility connection.

Capabilities

Tesvolt IA-62.5kW/500kWh has a longest listed configuration of 8 h, which points to capacity value, being counted on as supply when the network is tight. The specifications suggest renewable colocation, sitting next to a wind or solar plant and sharing its grid connection, and its AC block includes the inverter. The shortest listed configuration of 2 h makes it a candidate for peak shaving, cutting the power drawn from the grid at peak times.

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.
