The power range covers very different system sizes. The 1kW and 1.5kW models use a 12V battery platform because they target compact loads, while the higher-power 3kW class includes 24V models that can reduce battery-side current compared with a 12V design at the same power. This means the HF 1–3kW off grid inverter should be selected by exact model, not just by family name. Battery voltage, PV limits and charging specifications can change as the output class changes.
