The DS3-L-SPE 300VA from APsystems is the perfect microinverter for your balcony power plant. With this compact and lightweight (only 2.3kg) you can install a combination of PV modules of different types, in any orientation and in the desired number. The DS3 Series interacts with power grids through a feature called RPC (Reactive Power Control) to better manage photovoltaic power peaks on the grid. With an output of 300VA and an efficiency of 97.3%, a unique integration with 20% fewer components, APsystems set new standards for private and commercial photovoltaics.

Optimal reliability

Microinverter systems are inherently more reliable than traditional inverters. The decentralized structure of a microinverter system ensures that the entire PV system does not fail in the event of a fault. The microinverter is designed to operate at full power in ambient temperatures up to +65°C (150°F). The housing of the microinverter corresponds to protection class IP67.
