Normal Operation
Normal operation assumes the SP Pro will use the Fronius (solar power) to charge the batteries
and supply the loads during the day, use the battery during the night and use the generator when
needed. When this type of operation is desired, this is what the AC breakers must look like after
performing Step 5 of Power-up Procedure (see How to Power-up/shutdown my DropBear).
ByPass Operation
In the event of maintenance or failure of the SP Pro and/or the Fronius and there is no power
output from the system, you can configure the system to operate in ByPass mode. This will allow
the generator to provide power directly to the loads.
To use this mode, the system must be set to the following configuration:
1. Turn OFF all the AC breakers.
2. Turn OFF Main Battery Breaker and individual battery breakers.
3. Turn changeover switch from position 1 to position 2.
4. Turn ON generator AC breaker and Main Switch Out.
5. Manually start generator.
By doing this, the generator will provide power directly to the loads.
