The Battery Cabinet is an all-in-one energy storage solution featuring LFP (lithium iron phosphate) batteries, liquid-cooling technology, fire suppression, and monitoring systems for safe and efficient operation.
Designers must size batteries to meet energy needs for a chosen autonomy (days of no solar). Below is a careful, step-by-step calculation. 300 W × 24 hours = 7,200 Wh/day. 7,200 Wh/day × 2 days = 14,400 Wh required energy.
Cost range overview: Installed BESS for residential-scale systems typically falls in the $7,000-$30,000 band, with per-kilowatt-hour prices commonly around $1,000-$1,500 depending on chemistry and vendor.
Presently, the island has a 5 MW battery storage system installed on the grid at Trents, St. Another 15 MW have already been approved by the Fair Trading Commission (FTC), through the Clean Energy Transition Rider.
The cabinet is designed to house three EG4 WallMount All Weather 280Ah batteries on the interior and accommodate up to two EG4 Hybrid Inverters (such as the 12kPV, 18kPV, FlexBOSS18, or FlexBOSS21) in any combination to be mounted on the exterior of the box.
The Outdoor Cabinet Energy Storage System is a fully integrated solution that combines safe battery storage, intelligent power management, and weatherproof protection for solar and telecom applications.
