Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Netherlands that is ACM Netherlands. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- 215 kWh in one cabinet: Fifteen 14.3 kWh, 280 Ah modules fill the 768 V enclosure, 193.05 kWh of it usable at 90% depth of discharge.
- Fire suppression on board: Aerosol fire suppression and a circuit breaker come built into the cabinet.
- Smart fan cooling: BMS-managed fans move air through the cabinet across its -20 to 55 degrees C discharge range.
- 98.5% round-trip efficiency: Up to 98.5% of stored energy comes back out, with 1.1x overload tolerance in reserve.
- Scales to 4,300 kWh: Twenty cabinets operate in parallel, with up to 16 racks on a single PCS.
- Ready for remote supervision: TCP, RS485 and CAN ports plus an LCD reporting state of charge and fault codes.
Frequently Asked Questions
How large can a BOS-B installation grow?
One cabinet holds up to 215 kWh from fifteen 14.3 kWh modules, and twenty cabinets can run in parallel for 4,300 kWh, with as many as 16 racks per single PCS.
What voltage does the BOS-B present to the inverter?
The system nominal voltage is 768 V with an operating window of 208 to 876 V, which places it firmly in the high-voltage class of battery inverters.
What safety measures does the BOS-B include?
The cabinet integrates aerosol fire suppression, a circuit breaker and smart fan cooling, alongside an LCD that surfaces state of charge and fault codes.
Does the BOS-B suit outdoor placement?
No; its enclosure is rated IP20, so it belongs indoors. The cabinet measures 2150 x 1136 x 800 mm and weighs 680 to 1,944 kg depending on module count.
How efficient and durable is the BOS-B?
Round-trip efficiency peaks at 98.5%, cycle life exceeds 6,000 cycles to 70% remaining capacity, and the warranty covers 10 years.
