Briggs & Stratton PowerProtect+ DX 26kW Standby Generator (040810)

With the most starting power in the industry, the Briggs & Stratton® PowerProtect+ DX 26kW Standby Generator has enough muscle to handle the largest appliances, like a central AC, while keeping everything else in the home running during an outage. All PowerProtect+ generators are engineered to start a 5-ton air conditioner, delivering that power without forcing a step up to a larger, more expensive generator.

A commercial-grade Vanguard® 993cc engine delivers 26kW on liquid propane and 24kW on natural gas — the highest-output tier in the PowerProtect+ line. This DX+ model carries the line's exclusive front-facing exhaust, directing fumes away from the home for safer, more flexible installation, along with a Dura-Zen™-coated aluminum enclosure for corrosion resistance in harsh outdoor conditions. The GC-1033 controller integrates EnergyTrak™ remote monitoring, putting real-time generator status in a smartphone app and letting installers remotely diagnose issues before a service visit. The Eco-Cise™ weekly self-test runs its short 16-second cycle to verify readiness with minimal noise and fuel draw.

Backed by Briggs & Stratton's flagship 10-year comprehensive warranty — parts, labor, and travel, no hidden service costs — this is the generator for large homes that can't afford to compromise on backup power.

Specs & Details

AQs

Is this the most powerful generator in the PowerProtect+ line?
Yes — 26kW is the top output tier, with the highest motor-starting capability in the family.

Why is the LP rating higher than the NG rating?
Propane delivers more usable energy per unit volume than natural gas, so the same engine produces more output on LP — 26kW vs. 24kW here.

Does it need a transfer switch?
Yes, sold separately — size it to the 125A main breaker and your home's total electrical load.
