Adding a backup Generator (Solar Hybrid)
With the Optional Grid Fail / Generator Backup kit (see table below) an auto start backup generator can be
added to a SPMC model of the SP PRO in a single phase Solar Hybrid (grid connected) system.
When the grid fails the customer’s load power will be supplied from the battery bank until either the load
becomes too large for the system or the battery reaches a set SoC. At that point the generator will start to
run the loads and charge the battery bank. The generator will continue to run until either the battery bank
has recharged or grid power has been restored.

supplied with the Grid Fail / Generator Backup kit, available on the USB stick packed with the SP PRO or
