A home ESS lets you store solar by day and run the house at night, or ride through grid outages. The 51.2V (16s) LiFePO4 architecture is the industry standard for rack and wall units because it pairs with mainstream inverters over RS485 / CAN. This guide covers sizing, communication protocols and the import documents you need.

Frequently Asked Questions

Will a 51.2V rack battery talk to my inverter?
In most cases yes. Our 51.2V ESS uses RS485 and CAN with protocol presets for common hybrid inverters (Deye, Victron, Growatt, EG4 and others). Tell us your inverter model and we set the protocol before shipping.
How much storage do I need for a home?
Size to your evening load: take daily kWh used after sunset, add one day of backup, and choose 5kWh (starter), 10kWh (typical) or 15-30kWh (whole-house + EV). We help size from your bill.
What documents do I need to import?
CE, UN38.3, MSDS and a UN38.3 test summary are the baseline for sea freight and customs. We provide the full set with every shipment and can add IEC / UL quotes on request.
Do you supply installers and distributors?
Yes. We work with installers and distributors across AU, ZA, EU and the Middle East with sample orders, private label and volume pricing for framework agreements.
