OSCAL BP3600 Expansion Battery
The OSCAL BP3600 is a 3,600 Wh, 48 V LiFePO4 expansion battery built for the OSCAL PowerMax 3600 and PowerMax 6000 power stations. Each pack doubles the runtime of a single station, and up to fifteen packs stack on one station for a total of 57.6 kWh, enough to carry a home through multi-day outages or run an off-grid cabin.
The BP3600 charges and discharges through the main station at the same time, shows its status on its own LCD, and reports to the OSCAL app over Wi-Fi and Bluetooth. It shares the same rugged 590 x 350 x 441 mm footprint as the stations so units stack neatly. OSCAL backs it with a 5-year warranty. CSE Solar USA is an authorized OSCAL distributor.
