Designed for high-demand applications, the Gorilla Power GP12800D diesel generator delivers 12,800W maximum output with 12,000W running power. Built around a heavy-duty diesel set-up, it suits larger electrical loads where dependable backup or site power is required, with an ATS connection for automatic operation when paired with a transfer switch.
A 35 L fuel tank supports longer running periods, while recoil, key and electric starting options provide flexible starting methods. Low-oil shut-off adds engine protection, and the front panel layout includes 240V and 120V 32A outlets for connecting higher-draw equipment and low-voltage site circuits.
