It is better suited to startup-heavy loads than an inverter sized only around continuous wattage. The series provides up to 2× peak output and supports motor capacity up to 6HP, which gives the system more short-duration headroom when compressors, pumps or similar loads start. However, actual startup current varies widely by equipment. When using this single phase inverter for motor loads, installers should compare the appliance starting current, running current and backup priorities with the selected HESP model.
