SolarEdge Home Battery: choose 400V or 48V from the system outward.
The voltage in the product name is not a free preference. The existing or selected inverter, phase architecture, required capacity and backup design decide which SolarEdge battery family belongs in the bill of materials.
- 400V family
- About 9.7 kWh
- 48V family
- About 4.6–4.85 kWh
- Coupling
- DC-coupled
- Use case
- Self-use + optional backup
Per battery; primarily paired with compatible single-phase Home inverters.
Per module; check the exact BAT-05K48M0B revision and datasheet.
Compatibility with the inverter and firmware remains decisive.
Backup requires the correct interface and system design.
SolarEdge Home Battery 400V vs 48V
Use this as a routing table, then confirm the exact inverter-battery compatibility matrix and regional datasheet before ordering.
| Compare | Home Battery 400V | Home Battery 48V |
|---|---|---|
| Typical architecture | Compatible single-phase SolarEdge Home system | Compatible three-phase SolarEdge Home system |
| Capacity step | About 9.7 kWh per battery | About 4.6–4.85 kWh per module |
| Published scaling | Up to three batteries on supported systems | Up to five modules on supported systems |
| First check | Exact inverter model and firmware | Exact inverter model, battery revision and cable set |
Start with the inverter, not the battery price
For a new system, select the phase architecture and compatible SolarEdge Home inverter together with storage. For a retrofit, record the full inverter model, firmware and installed communication hardware before requesting a battery. “SolarEdge-compatible” is too broad for a purchase order.
The 400V family is associated with compatible single-phase Home systems; the modular 48V family is associated with compatible three-phase Home systems. Use the current compatibility matrix for the precise inverter and country combination.
What BAT-05K48M0B-02 identifies
BAT-05K48M0B-02 is a part number in the SolarEdge Home Battery 48V family. It identifies a battery module, not automatically a complete installed stack. Inter-module cables, the inverter cable set, top cover and mounting parts can be separate line items.
Ask suppliers to quote the complete tower for the intended module count. This prevents a low module-only price from being compared with a complete kit from another distributor.
Backup and energy management are design choices
A battery does not make a site outage-ready by itself. Define whole-home or selected-load backup, required power, phase behaviour and any black-start expectations. The design may need a SolarEdge Home Backup Interface and changes to the distribution board.
For self-consumption or dynamic tariffs, confirm the meter and communications needed for SolarEdge ONE and monitoring. Include commissioning responsibility in the quote rather than treating software setup as an afterthought.
SolarEdge battery procurement checklist
Use one completed checklist for every site so distributors quote the same system boundary.
- Full inverter type, serial generation and firmware
- Single- or three-phase grid connection
- Required energy, power and expansion reserve
- Battery part number and number of modules
- All cable, cover, stand and mounting kits
- Backup interface, meter and communications where required
Frequently asked questions
Can I choose 400V or 48V based on capacity alone?+
No. The inverter and phase architecture decide which family is compatible. Capacity is sized after that route is established.
Is BAT-05K48M0B-02 a complete battery system?+
It is a 48V battery-module part number. A complete installation can additionally require module and inverter cable sets, a top cover, mounting parts, a compatible inverter, metering and backup hardware.
Can a SolarEdge Home Battery provide backup power?+
Yes, in a supported backup design with the correct inverter, interface, electrical protection and commissioning. Verify local grid and installation requirements for the project.
How should professional buyers compare SolarEdge battery prices?+
Compare identical manufacturer part numbers and include every required accessory, packing unit, delivery cost and warranty route. A module-only price and a complete tower price are not comparable.
Technical content checked against manufacturer information. Product specifications and compatibility can change; use the current regional datasheet and installation documentation for the final design.
