Product Overview
The Enphase B05-C01-US00-1-3 is the 5.0 kWh battery unit used to build an Enphase IQ Battery 10C. A complete IQ Battery 10C (ordering SKU IQBATTERY-10C-1P-NA) is made of two of these battery units plus one IQ Battery 10C cover kit (B10C-NC-0708-O). Together they make one 10.0 kWh AC-coupled home battery with built-in IQ8B microinverters and a battery management system.
Enphase lists this part as the standard ordering SKU for the 10C's 5 kWh battery unit, so it is useful when a 10C is ordered as separate line items. On its own, one unit is not a complete battery system. You need two units and the cover kit to finish one IQ Battery 10C.
Best For
- Building an IQ Battery 10C from separate parts: Order two battery units and one cover kit to make one complete IQ Battery 10C.
- Project bills of materials: Permit sets and parts lists sometimes list the 10C's unit and cover kit SKUs separately. Enphase notes that interconnection applications and permits should use the model number, not the ordering SKU.

What You May Also Need
Usually required
- A second B05-C01-US00-1-3 battery unit: One IQ Battery 10C uses two units.
- IQ Battery 10C cover kit (B10C-NC-0708-O): Includes the cover and the interconnect power and control cables that join the two units.
- Enphase IQ Combiner 6C and IQ Meter Collar: Enphase's 10C quick install guide says the system requires both for backup operation.
May be required
- IQ Battery 10C Pedestal Mount: For floor mounting on a pedestal instead of a wall.
Optional upgrades
- Complete IQ Battery 10C kit: If you'd rather order the whole battery as one SKU (two units plus cover kit).
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Not a stand-alone battery. Enphase describes the IQ Battery 10C as two 5 kWh units plus a cover kit. It does not describe using one unit by itself.
- Backup needs the IQ Combiner 6C and IQ Meter Collar. Enphase's quick install guide says the system requires both for backup operation.
- Don't mix with the IQ Battery 5P. Enphase's IQ Battery 10C system-planning guide (June 2026) says the 10C is not compatible with the IQ Battery 5P. Enphase says 5P compatibility is planned for the future.
- Heavy. Plan for a lift of up to 125 lb per Enphase's maximum lifting weight.
- Installation. Install to electrical code, local rules and Enphase's IQ Battery 10C quick install guide.
