15.36kWh. One Unit.
A single 5kWh or 10kWh battery often isn't enough. The B-LFP48-300E delivers 15.36kWh from one unit — handling higher daily loads without stacking multiple smaller modules. Need more? Scale up to 967.68kWh across 63 units on a single platform.
Own Your Energy
Pair the B-LFP48-300E with your solar system and take control of your energy bill. Store what you generate during the day, use it at night, and keep your household running through outages — without relying on the grid.
Light Up Every Classroom
Schools run on more than lesson plans. The B-LFP48-300E keeps classrooms lit, devices charged, and facilities operational — storing solar energy during school hours and supporting evening programs when the grid falls short. Reliable energy is part of the curriculum.
Off-Grid, No Compromise
For island resorts and remote communities where grid access is limited or unreliable, the B-LFP48-300E delivers consistent, scalable energy storage. Less dependence on diesel. More stability for the people who live and work there.
Harvest More, Spend Less
Irrigation, lighting, cold storage, equipment — farms demand reliable power around the clock. The B-LFP48-300E pairs with solar to reduce fuel and grid costs, with enough capacity to scale alongside your operation. When harvest season comes, your power won't let you down.
