A synchronizing panel is required when there are more than 1 Generators in an installation. The panel acts when the electrical mains fail, it calculates the load required by the facility, then switches on the generators as required. It then synchronises the gensets with each other and balances the facilities load between them. This is after a delay period that is adjustable. The generators will take an initial warm-up period after which it will synchronize with each other. This warm-up period is also adjustable as per requirement.
