Modular Pylontech storage for compatible solar and backup systems.
Pylontech offers low-voltage rack batteries such as the US5000 alongside modular high-voltage Force systems. The correct family depends on the inverter voltage, approved communications, required capacity and installation environment.
Low-voltage rack storage and high-voltage stacks are not interchangeable.
Pylontech’s US series uses modular low-voltage rack-mounted batteries. Force systems use a different stacked architecture. Inverter voltage, battery-management communication and the current compatibility list determine which route is valid.
US5000
The current manufacturer specification lists 4.8 kWh nominal and 4.56 kWh usable capacity per module, 95% depth of discharge and CAN/RS485 communications.
Force systems
High-voltage modular stacks can suit compatible hybrid designs where the correct control module, number of battery modules and inverter are specified together.
Expansion projects
Adding batteries requires checks on model generation, age, state of charge, firmware, cable configuration, current limits and manufacturer rules.
What does one 4.8 kWh US5000 module provide?
The manufacturer lists 4.56 kWh usable capacity for the current US5000 specification. Modules can be combined within approved limits, but battery energy and inverter power remain separate constraints.
Illustrative examples
- One US5000: roughly 4.5 hours at a steady 1 kW load before conversion losses
- Two modules: roughly 9 hours at 1 kW, subject to reserve and system settings
- A 3 kW load could use one module’s listed usable energy in around 1.5 hours
- Adding modules extends runtime but does not automatically increase inverter kW output
Figures are simple energy illustrations, not guaranteed runtime. Allow for battery reserve, conversion losses, temperature, ageing and changing household demand.
Compatibility comes before capacity.
- Exact inverter make, model and firmware
- Approved battery family and communication protocol
- Charge and discharge current limits
- Rack, cabinet or stack layout and clearances
- Protection, isolation, cabling and earthing
- Monitoring, commissioning and warranty registration requirements
Existing Pylontech system?
We can assess suitable expansion, monitoring or fault concerns. Do not add a different model or connect modules without checking the manufacturer’s mixing and master-battery rules.
Send photographs of every model label and the inverter details before arranging work.
