HE310-5000-F — 5000 W Low-Frequency Inverter
One line: An industrial-frequency inverter for the loads that punish high-frequency units — pumps, motors, compressors. 5000 W / 6300 VA, 48 V, with a no-load loss below half that of a same-power high-frequency unit.

Why low frequency
A low-frequency inverter steps voltage through a large iron-core transformer before the output stage. The trade-off is honest:
| Low-frequency (this model) | High-frequency (HE200 / HE300) | |
|---|---|---|
| Size and weight | Large, heavy | Small, light |
| No-load loss | Below half of a same-power high-frequency unit | Higher |
| Inductive / surge load tolerance | Better | Adequate for ordinary loads |
| Load peak ratio | 3:1 | Model-dependent |
The 3:1 peak ratio is the number that matters for motor loads: a 1.5 kW pump with a 4.5 kW starting surge sits inside this unit's capability, where a high-frequency unit of similar rating may trip.
Low no-load loss matters on systems that idle for long periods — a unit that draws less when nothing is running wastes less energy from a finite battery bank.
Features
- Optional BMS communication.
- Optional PWM / MPPT solar charge controller.
- No-load loss below half that of an equivalent high-frequency unit.
- Pure sine wave output suited to varied loads.
- Output short-circuit protection.
- Multiple user-adjustable parameters.
- Large LED display — AC voltage and frequency, PV voltage and current, output voltage and frequency, battery voltage, load current.
Typical applications
- Agricultural irrigation pumps, where motor surge is the design constraint.
- Workshop machinery with inductive loads.
- Sites with poor or unstable grid supply, where the wide 154–264 VAC input window helps.
- Any installation where a low no-load loss over long idle periods matters.
