Modular 5 kWh LiFePO4 Battery
A modular 48V 100Ah 5 kWh LiFePO4 storage battery with a smart BMS, 6000-cycle Grade A cells and parallel expansion to about 90 kWh for scalable home and light-commercial storage.
Store your solar, use it any time
A LiFePO4 (lithium iron phosphate) battery stores surplus solar by day and powers the home at night or during outages. LiFePO4 chemistry is safe, stable and long-lived, delivering thousands of deep cycles with a built-in smart BMS that protects every cell.
Modular packs stack in parallel to grow from a few kWh to tens of kWh, and speak CAN/RS485 to all mainstream inverters. OCALWA supplies wall-mount, floor-standing, rack and portable formats matched to your inverter and storage target.

Why choose LiFePO4 storage
Safe and long-lasting
LiFePO4 runs cooler and safer than other lithium types and lasts 6000+ cycles, years of daily use.
Grows with your needs
Add packs in parallel to reach the kWh you need, up to tens of kWh per bank.
Works with your inverter
CAN/RS485 comms match all mainstream hybrid and off-grid inverters for plug-and-play setup.

Frequently asked questions
These LiFePO4 packs are rated for over 6000 deep cycles at 80% depth of discharge, which is well over ten years of daily cycling.
Yes. Packs connect in parallel, so you can start small and add capacity later up to the bank limit, all managed by the BMS.
Yes in most cases. With CAN/RS485 communication these batteries pair with all mainstream hybrid and off-grid inverters; tell us your inverter and we confirm the protocol match.
Yes. LiFePO4 is the safest mainstream lithium chemistry, thermally stable and non-flammable in normal use, with a smart BMS cutting off on fault. It is widely installed in garages and utility rooms.
Yes. We consolidate matched inverters, batteries, panels and balance-of-system from one verified factory into full containers, with export documentation, certification and quality control managed by OCALWA.
