SolarMax 3000S - Operation; DC Isolating Switch and Startup

en
6 Operation
All SolarMax S series inverters work completely automatically and maintenance-free. The
electrical isolating switch between the PV generator, inverter and the 230 V mains always
remain activated. If enough irradiance is present, the inverter starts operating and feeds
the output into the 230 V mains; otherwise, the device goes into a wait mode and in this
way is ready to feed the mains at any time. The electronics are separated from the mains
during the night.
6.1 How the DC isolating switch works
Switching off the DC isolating switch disconnects the inverter from the PV generator.
DANGER
Even when the DC isolating switch is switched off, the components and connections
of the inverter are still live!
6.2 Switching on the inverter
Procedure
Action Reaction
1. Switch on the DC insulation switch. After several seconds the Overview menu is
displayed. The message “Startup…” appears
in the “Status” line.
The status LED blinks green.
2. Switch on any external AC isolating
switches/fuses (if present)
After 30 seconds, the inverter is in mains op-
eration. In the “Overview” display, the “Mains
operation” device status is shown.
The status LED glows green.
NOTE
When the inverter is commissioned, instead of the “Overview” menu, an “Initial Set-
up” menu appears; see section 5 “Startup”.
