Turn on the DC supply to the SP PRO(s). Leave the inverter(s) in IDLE
•
Connect SP LINK to the SP PRO inverter(s).
• Turn off all charging sources such as any connected AC or DC coupled solar power..

SP PRO front panel Generator button.
If generator does not start then check control wiring and SP PRO con-
figuration settings.
For manual start generator, Start the generator manually.
In
SP LINK, Data View - Now tab check the “AC
Source Voltage” and AC Source Frequency” before
the SP PRO syncs to the generator.

time (default is 1 min) and check that the generator runs the load and
charges the battery bank.

• C
heck the “AC Source Power”to ensure this is less than or equal to the
generator capacity. If wrong then adjust the “AC Source Power” setting in
Configuration settings
• C
heck the “AC Source Frequency” to ensure it has not dropped too low
(>48 Hz). If too low then drop the “AC Source Power” setting in Configu-
