The APsystems DS3 takes a different approach: rather than one inverter per panel, it's a dual microinverter — one unit, two panel inputs, one cable output. Fewer components, fewer connectors, tidier result.
Output
Rated at 730W maximum, not 800W. The difference in annual generation is around 45kWh — roughly £11/year at standard tariff rates. If that matters to you, the Hoymiles HM-800 is the right product. If it doesn't, the DS3's single-cable simplicity is a genuine practical advantage.
The verdict
The right choice for buyers who value install simplicity over maximum wattage. Slightly less than 800W, slightly more per watt, noticeably tidier result.
