• SOLAR: If you have only solar converters in the system, set Solar Mode to “SOLAR”. Also set the “Float Charge Voltage
(Solar)” parameter to the desired float setting.
NOTE!
When solar converters are all installed prior to applying power and starting system, the NCU will NOT communicate
with solar converters until SOLAR MODE is enabled.
7.6 Checking System Status
Procedure
1. Observe the status of the indicators located on the controller, rectifiers, solar converters, -48 VDC to +24 VDC converters or
-48 VDC to -58 VDC converters (if furnished), and inverters (if furnished). If the system is operating normally, the status of
these is as shown in Table 7.2.
