Pramac BSO MAX 125kW / 261kWh Outdoor Battery Storage System

Pramac BSO MAX 125kW 261kWh Outdoor BESS | High-Capacity Commercial Battery Storage UK

Meta Description:

High-performance all-in-one outdoor battery storage. 125kW power and 261kWh capacity for larger commercial peak shaving, solar optimisation and backup applications. Fast-deploying BESS from Powerland.

Product Description:

The Pramac BSO MAX 125/261 delivers higher power and capacity in the same compact, all-in-one outdoor format as the 90/188 model. With 125kW on-grid capability and 261kWh of energy storage, this system is ideal for medium-to-large commercial and industrial sites that need greater peak-shaving headroom or support for larger solar arrays and critical backup loads.

Like all BSO MAX models, it features Pramac’s proprietary Energy Management System with web-based commissioning, real-time energy flow visualisation, and intelligent scheduling. The system excels at peak demand reduction, solar self-consumption optimisation and automated energy arbitrage, delivering measurable savings on your electricity bills while improving sustainability metrics.

Its robust outdoor-rated enclosure, redundant climate control and comprehensive safety systems (including aerosol fire suppression and multi-layer monitoring) ensure reliable operation in demanding UK environments. The fast switchover to backup mode provides seamless protection for sensitive processes or essential services.

Key Benefits

•  Higher power density for sites with larger peak loads or solar generation

•  Same fast-install, low-civil-works advantages as smaller BSO MAX units

•  Advanced EMS with remote monitoring, forecasting and optimisation

•  Safe LFP chemistry with long cycle life and low maintenance

•  Scalable architecture – easily parallel multiple units

•  Strong ROI through reduced demand charges and increased renewable utilisation

Ideal for: larger factories, distribution centres, data centre support facilities, agricultural processing plants and commercial sites with substantial solar or high evening/weekend loads.
