NOTE

• Wiring of the PV module

· Number of PV modules in series should 

obey

 the condition that the open circuit voltage of the PV strings is not higher

than 350V DC when the ambient temperature is from -20°C to 40°C, and the minimum operation voltage is higher than 110V.

· The number of the PV strings must 

be 

three

 or less

. The number of PV modules in series of each PV string can be

different if the above condition is satisfied. The short circuit current of each PV string must be lower than 10A.

• DC Disconnect

· Rated input voltage of the DC disconnect switch must be 400V DC or over.
· Grounding terminal must be connected to the PV frame and solar power conditioner.

• AC Disconnect

· The AC disconnect switch must be capable of disconnecting the 240V-30A / AC.
· Supply over current protection fuse of 30A.
· Grounding terminal must be connected to the solar power conditioner and the AC load center.

Ask SHARP authorized dealer for PV modules or the AC&DC disconnects if necessary.

3. Confirm that breaker on the DC disconnect is in OFF status. If it is in ON status, turn it to OFF

status.

4. Confirm that the dedicated breaker for the solar power conditioner on the AC load center, and the

breaker on the AC disconnect is in OFF status. If they are in ON status, turn them to OFF status.
