An inverter and its battery have to be specified together. The battery's continuous discharge rating has to cover what the inverter draws at full load, and the BMS has to allow that current without tripping — a mismatch here is the most common reason an otherwise healthy system shuts down under load.
What we match
- Voltage — 12V, 24V or 48V to suit the inverter input.
- Continuous current — battery and BMS rated for the inverter's full-load draw, not its idle draw.
- Surge headroom — allowance for motor and compressor start-up so the pack does not cut out on inrush.
- Capacity — sized for the runtime you actually need, at the load you actually run.
Tell us the load, not the battery
The most useful thing you can send is a list of what the system has to run and for how long — not a battery size. We will work back from the load to the pack, and tell you if the inverter you have in mind is the right one for it.
Need this built to your own specification?
Send us the voltage, capacity, discharge current and the space you have — or a photo of the battery you are replacing. We will come back with a specification and a price.
