Page 7: The Advantages Of An Apsystems System
When using an APsystems microinverter, PV modules are connected in parallel. Voltage at the back of each PV module never exceeds PV modules Voc, which is lower than 60 Vdc for most of PV modules used with APsystems microinverters. This low voltage is considered “safe to touch” by firemen department and will avoid risk of electrical shock, electrical arcs and fire hazards. -
Page 8: Apsystems Microinverter Ds3 Series Introduction
A 24/7 energy access through Apps or web based portal facilitate remote diagnosis and maintenance. The DS3 series is interactive with power grids through a feature referred to as RPC (Reactive Power Control) to better manage photovoltaic power spikes in the grid. With a performance and an efficiency of 97%, a unique integration with 20% less components, APsystems DS3-L and DS3 are a game changer to residential and commercial 3.2 Features of the DS3 microinverter... -
