Real-Time Monitoring, Built In
Monitor your battery system in real time from any device — no extra gateway, no extra cost. Built-in WiFi and Bluetooth put full system visibility in your pocket, with RS232, RS485, and CAN support for seamless inverter integration.
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.
B-LFP48-300E Compatible Inverters: Single-Phase and Three-Phase
The BSLBATT B-LFP48-300E is listed as compatible by 20 inverter brands, including Deye, Solis, LuxPower, SolaX and SOSEN. The list covers both single-phase and three-phase low-voltage hybrid inverters, which matters for the commercial and off-grid projects this 15kWh module is built for.

Many schools, farms and small commercial sites run on three-phase supply. The compatibility list includes three-phase low-voltage hybrid inverters from Deye, Solis, LuxPower, SolaX and SOSEN, so a 300E bank can serve these sites as well as single-phase homes.
In a multi-module bank, the master module collects data from the other modules and reports it to the inverter over CAN or RS485. No extra gateway is needed.
Protocol Support for 30+ Inverter Brands
Beyond the listed models, the B-LFP48-300E firmware includes CAN and RS485 communication protocols for 30+ inverter brands. For an inverter model not shown in the table above, send the model number to BSLBATT technical support to confirm the protocol setting before commissioning.
Can the B-LFP48-300E work with a three-phase inverter?
