Compact 5kWh solar battery
Rack it. Stack it.
Build the system your way.
PowerThor 5000 combines a 5.12kWh LiFePO4 pack, intelligent battery management and flexible rack or stacked installation for residential solar and backup systems.
Flexible installation
Slim, quiet and ready for the rack.
The 135mm enclosure can be stacked on a suitable trolley or installed in a compatible battery rack. Passive operation keeps the module quiet, while front-facing connections simplify access during commissioning and service.
- 135mm slim enclosure
- Approx. 41kg module weight
- Stacked or rack-mounted installation options

Smart JK BMS
Protection, active balancing and Bluetooth diagnostics.
The integrated inverter BMS monitors per-cell voltage, temperature, current and state of charge. Active balancing supports cell consistency, while local Bluetooth diagnostics help installers review battery information during commissioning.
- 100A inverter BMS
- 1A active cell balancing
- Bluetooth access to real-time battery data

Broad compatibility
CAN and RS485 for compatible solar inverters.
PowerThor 5000 is designed to exchange operating limits and battery status with supported 48V-class inverters. The exact protocol, pinout and firmware must be confirmed for the selected inverter before the system is commissioned.
- CAN and RS485 communication
- Support for a range of mainstream inverter platforms
- Protocol selection must match the inverter model and firmware

Integrated protection
A dedicated DC breaker at the battery interface.
The front panel includes a DC circuit breaker as part of the battery’s protection architecture. Final installation still requires correctly rated upstream protection, cabling, isolation and earthing designed for the complete energy-storage system.
- Front-access DC circuit breaker
- Protected positive and negative battery connections
- System-level protection must be sized by the installer

Modular expansion
Start with one module and scale capacity in steps.
Supported parallel operation lets the battery bank grow as energy needs change. Expansion should use matched modules and a coordinated design for rack space, busbars, cables, protection, communication and inverter current limits.
- Up to 16 supported units in parallel
- Modular capacity for solar self-consumption and backup
- Suitable for residential and small commercial planning

Where it fits
A flexible first step into solar battery storage.
PowerThor 5000 is aimed at smaller home, cabin and essential-load systems that need a compact battery for a solar inverter. Its stackable or rack-mount format, 51.2V architecture and default communication profiles support practical on-grid backup and off-grid planning.
Buyer’s guide
Matching a 5kWh battery to a solar inverter.
Start by checking the inverter’s supported battery voltage, current and communication protocol. Then compare the 5.12kWh nominal energy with the intended backup duration and the 100A maximum discharge current with simultaneous load demand.
Confirm inverter compatibility
PowerThor 5000 uses CAN configured for Victron Energy by default and RS485 configured for Growatt by default. Confirm the exact inverter model, protocol and firmware before installation.
Estimate essential-load energy
Multiply each load by its expected operating time and add the results. Allow for conversion losses and battery operating limits instead of assuming all 5.12kWh will reach AC loads.
Plan staged expansion
One module can begin a compact system. If the backup target grows, reserve space, busbar capacity, protection and communication planning for the supported parallel configuration.

Solar battery knowledge
Solar inverter battery basics, explained.
Why inverter communication matters
A compatible communication link lets the battery management system share limits and status with the inverter. Without the correct profile, a cable that physically fits may still fail to provide closed-loop control.
Why LiFePO4 suits off-grid cycling
Off-grid batteries may charge and discharge every day. PowerThor 5000 uses LiFePO4 chemistry and is rated for 6,000 cycles at 80% depth of discharge to 80% state of health under the stated conditions.
What a 48V solar battery actually means
The common 48V label describes the system class. A 16-series LiFePO4 pack has a 51.2V nominal voltage, and its operating voltage changes with state of charge. Inverter settings must follow the battery specification rather than a generic 48V assumption.
A precise fit
A compact 5kWh battery for solar and backup.
PowerThor 5000 fits buyers looking for a 5.12kWh LiFePO4 solar battery, a 51.2V 100Ah inverter battery or a compact rack battery for home backup and off-grid use.
With Victron-oriented CAN, Growatt-oriented RS485 and modular parallel capability, it is a flexible starting point for residential 48V battery storage and expandable solar energy systems.
