SolarEdge Home Battery 48V (W) BAT-05K48M0W-014.85kWh 48V LFP tower module for SolarEdge Home Hub three-phase

Overview

The BAT-05K48M0W-01 is the SolarEdge Home Battery 48V (W), a 4.85kWh lithium iron phosphate module approved for installation in Germany and Austria. It works with SolarEdge Home Hub Inverters Three Phase and stacks with up to three more modules in a single tower, for 19.4kWh per inverter, using Quick Connect plugs rather than module cables. A single module charges at 2825W and discharges at 4096W, two or more reach 5000W. The 50.5kg, 725mm-wide module needs the floor stand and top cover kit and carries a 10-year warranty.

• 4.85kWh usable per module at 100% depth of discharge
• Up to four modules in a single tower per inverter
• Quick Connect stacking, no cables between modules
• 5000W continuous charge and discharge from two modules
• IP65, natural convection, mandatory floor stand
• Approved for installation in Germany and Austria only

How it works

The Home Battery 48V (W) is a low-voltage lithium iron phosphate module for DC-coupled storage on SolarEdge Home Hub Inverters Three Phase (SE*K-RWB48). Modules are stacked into one tower and joined through Quick Connect plugs, so no cables run between them; only the top cover is wired to the inverter with DC, ground and communication cables. RS485 links the modules, CAN bus carries data to the inverter, and the battery is configured automatically in SetApp.

Key features

Each module provides 4850Wh of usable energy at 100% depth of discharge over a 44.8–57.6V range. A single module charges at 2825W and discharges at 4096W; from two modules upwards both directions reach 5000W, and four modules give 19.4kWh per inverter. Peak round-trip efficiency exceeds 95.4%. The IP65/NEMA 3R enclosure is cooled by natural convection and stays below 25dBA. Power is derated above 40°C and below 15°C internal temperature, with internal heating for cold charging.

Installation and compatibility

SolarEdge approves this version for installation in Germany and Austria only. The accessory kit IAC-RBAT-5KWACC-01, with floor stand and top cover, is mandatory for each tower, and only one tower is allowed per inverter. Each module weighs 50.5kg and is also secured to the wall with two brackets, so the guide calls for at least two qualified installers. The inverter connection uses cable set IAC-RBAT-5KCINV-01, and a full four-module tower with stand and cover is 1735.5mm high.

Monitoring and settings

After power-up the inverter detects the tower and SetApp completes the configuration without manual battery settings. State of charge, power flows and alerts are shown in the SolarEdge monitoring platform and app together with PV production. Backup is available for residential installations only, subject to local regulations, and may need extra components and a firmware upgrade.
