Choose by application,
not by capacity alone.
Use power, usable energy, electrical compatibility, site conditions and destination-market requirements to compare battery and inverter families for a B2B project.
What information selects the right storage system?
Start with the application, then specify required power in kW and usable energy in kWh. Confirm voltage, phase, PV and battery interfaces, communications, installation conditions and local requirements. Only then compare models within the relevant product family.
kW and kWh answer different questions.
Power
The rate at which the system supplies or accepts energy. Use it to describe the loads, inverter output and charge or discharge requirement.
Energy
The amount of energy stored. Use it with the expected operating profile or backup duration to define the required system size.
Compare the relevant application group first.
| Application group | Published range | Typical screening context |
|---|---|---|
| Residential batteries and all-in-one systems | 0.64–40.93 kWh; selected all-in-one families include 3–10 kW output | Home solar storage, backup and light-duty or mobile applications |
| Commercial and industrial cabinets | 50–261 kWh; selected integrated families include 20–125 kW | Commercial storage, backup, renewable integration and microgrid projects |
| Hybrid inverters | 3–33 kW | Single-phase and three-phase solar-plus-storage systems |
These are catalogue screening ranges, not a project design or an availability statement. Confirm the final model and configuration.

Common energy storage selection questions.
What is the difference between kW and kWh in energy storage?
kW describes power: how quickly a system can supply or accept energy. kWh describes energy: how much energy is stored. A project normally needs both a power requirement and an energy requirement.
Should I choose a battery before choosing an inverter?
Treat the battery and inverter as a compatible system. Confirm battery voltage, inverter battery-input range, charge and discharge limits, communications and the intended grid or backup operating mode before final selection.
How should I compare air-cooled and liquid-cooled C&I cabinets?
Cooling method is one design input. Compare the project duty cycle, ambient conditions, energy and power requirement, site layout, controls, service plan and applicable safety requirements before choosing a cabinet configuration.
Which project details are needed for an energy storage quotation?
Provide the application, site load or target power, required usable energy, system quantity, grid phase and voltage, PV information where relevant, installation environment, destination market, certification needs and timeline.
Do published catalogue specifications confirm local compliance?
No. Catalogue information supports product screening. The final model, configuration and certifications must be checked against the destination market and project requirements before ordering or installation.
