Overview
The GP8000E COsense is a conventional open-frame gasoline generator for home backup: 8,000 W running / 10,000 W starting (Generac's 'PowerRush' surge marketing is not conflated with the rated figure). Its 420 cc engine feeds a 120/240 V panel with an L14-30R twist-lock and two GFCI-protected 120 V duplex outlets. COsense carbon-monoxide shutdown is documented in the GP-series manual and reflected by the panel's Red/Yellow COsense indicators. Electric and recoil start; not parallel capable. Runtime is 15 h at 25% / 10 h at 50% load on the 7.9 gal tank. As a conventional AVR unit it publishes no numeric THD, and Generac lists no official dBA figure for it — both recorded as unknown. The 7675-4 is the 49-State configuration (not CARB certified; 50-State CARB SKUs exist separately as 7676-x).
Variant note: Model 7675-4 (49-State). CARB/50-State variants are 7676-x SKUs — distinct entities, not merged. GP-series shared owner's manual used for the CO-shutdown and feature descriptions.
Data note: Confidence medium for conflicts across official sources. WEIGHT CONFLICT: spec sheet lists 90.0 kg while the GP-series manual lists a dry weight of 197.1 lb (89.4 kg) — spec sheet value used, both preserved. WARRANTY CONFLICT: residential term is a consistent 3 years, but the commercial term differs (1 vs 2 years) across sheets — residential 3 yr recorded, conflict noted. 'PowerRush'/surge marketing is never conflated with the 8,000 W rated figure. THD not stated (conventional AVR) → null, sensitive-electronics suitability low. No official dBA figure → noiseDb null, noiseClass unknown. CARB: 7675-4 is the 49-State config (not CARB certified); 50-State CARB configurations exist as separate 7676-x SKUs and are not conflated here. EPA certified true.
Specifications
Running and starting watts are never collapsed; every runtime figure carries its fuel and load basis; THD is shown only when officially stated numerically. Core values' original claims and sources are in the provenance table. The final group is computed from the fields above and marked as derived.

Strengths and weaknesses
Strengths
- 8,000 W running / 10,000 W starting with 120/240 V and an L14-30R
- COsense CO auto-shutdown documented in the GP-series manual
- GFCI 120 V outlets and covered receptacles; electric start
- 15 h at 25% load runtime on a 7.9 gal tank
- Folding handle and wheel kit for one-person moves despite 90 kg
Weaknesses
- Conventional AVR — no numeric THD published, not flagged for sensitive electronics
- No official dBA noise figure — noise unknown, excluded from ranking
- No TT-30R and single-fuel gasoline only — not RV-outlet equipped, no fuel fallback
- Not CARB compliant (7675-4 is 49-State; 50-State CARB SKUs are 7676-x)
- Official weight conflict (spec sheet 90.0 kg vs manual 89.4 kg) and commercial-warranty term conflict across sheets
