PowerBlock — integrated BESS block with PCS and MV transformer 4.8–20+ MWh

PowerBlock combines SolBank battery containers, an inverter, an MV transformer and an EMS into one block of 4.8–20+ MWh usable capacity with a 10, 22, 33 or 34.5 kV output. It connects straight to the medium-voltage grid at utility storage, solar and wind sites.

Description

Discharge duration is set by the block configuration, from 1.5 to 4 hours and beyond. AC-side round-trip efficiency is at least 90 %, which already includes inverter and transformer losses and can go straight into the financial model. Power factor is adjustable over −1…1, so the block can supply or absorb reactive power for voltage support. Frequency is 50 or 60 Hz. Control and communication systems ship with the power equipment, giving the project a single interface to the dispatcher. Several blocks are paralleled on the MV side to build a gigawatt-hour-class plant. Certification is to UL 9540 and IEC 62933.

How to choose

PowerBlock is the pick when the client wants a 10–34.5 kV connection point without sourcing the PCS and transformer separately. If the inverter and substation exist or are designed separately, SolBank 3.0 or 4.0 battery containers at 5,016 and 6,250 kWh cost less. Sites up to 940 kWh on a 480 or 800 V connection are better served by KuBank cabinets with built-in PCS.

FAQ

What grid voltage does PowerBlock connect to?

The AC output runs through its own transformer at 10, 22, 33 or 34.5 kV, 50 or 60 Hz.

What round-trip efficiency does PowerBlock BESS achieve?

At least 90 % on the AC side, including inverter and transformer losses.

Can PowerBlock supply reactive power?

Yes, power factor is adjustable within −1…1, so the block can both supply and absorb reactive power.

How is a PowerBlock plant scaled up?

Blocks of 4.8–20+ MWh are paralleled on the MV side to reach gigawatt-hour capacity.
