Wholesale Solar’s 28kW off-grid Kohler generator package includes all the essential components for a large off-grid generator installation. This package includes dual Kohler 14RESA generators combined in parallel using Kohler’s PowerSync Automatic Paralleling Module. PowerSync automatically synchronizes the two 14RESA generator sets for combined output of up to 28kW continuous AC power. The PowerSync module runs one generator set when power requirements are low, and automatically starts, synchronizes, and connects the second generator set when the load increases. PowerSync also provides redundancy, if one generator set requires service or fails the other generator is still available to power critical electronics.

Our package also includes OnCue system monitoring, maintenance kits, and the carburetor and fuel regulator heaters for reliable starting in cold climates. Batteries are not included, requires (2) group 51 automotive starter batteries.

Note: Parallel generator sets need to be installed by a Kohler-authorized installer.
