DC switch
DC switch (as shown in the
①
of Figure2-8) is the connection switch of inverter and PV array.
When the inverter works normally, the DC switch must be ON. During installation and wiring, the
DC switch must be OFF. Before maintenance, the DC switch must be OFF for 5 minutes, and
measure the voltage of DC busbar by multimeter, only when the voltage less than 10V, the
maintenance can be done.
When maintenance or wiring, the DC switch must be disconnected.
2.3 Application Scenes
The iStoragE can be applied in DC-coupled systems (mostly new installation), AC-coupled systems
(mostly retrofit) and hybrid-coupled systems (mostly retrofit, and PV capacity -increase), as shown in
Figure2-10, Figure2-11and Figure2-12.
