The ds3-l-spe 400va from APsystems is the perfect microinverter for your balcony power plant. With this compact lightweight (only 2.3kg) you can install a combination of PV modules of different types, in any orientation. The DS3 series interacts with power grids through a feature called rpc (Reactive Power Control) to better manage photovoltaic power peaks in the grid. With 400va output and 97.3% efficiency, unique integration with 20% fewer components, APsystems set new standards for residential and commercial photovoltaics.

Optimal reliability

Micro-inverter systems are inherently more reliable than conventional inverters. The decentralized design of a microinverter system ensures that the entire PV system will not fail in the event of a malfunction. The microinverter is designed to operate at full power in ambient temperatures up to +65°C (150°F). The microinverter's enclosure is IP67 rated.
