≈ 0.9 days (24h/day) · Safe motor start buffer (75.4% margin).
1/2 HP well pump running (1,250 W max) and start-up (3,800 W max) draw fit the DuroMax XP13000EH's 10,500 W running / 13,000 W starting ratings.
shallow water table with low head pressure demand (850 W run, 2,500 W surge)
standard 100-ft deep residential well cycling on 30/50 PSI pressure switch (1,050 W run, 3,200 W surge)

Provides 4× CEE 7/3 (230V), 1× Commando (16A/32A) (120/240V 60Hz).
Inverter alternator with ≤12% THD. Safe for microprocessor-controlled appliances.
Inductive motor/compressor load with 3× starting surge (motor inrush) (75.4% worst-case surge margin).
Never operate indoors or in attached garages due to lethal carbon monoxide (CO) exhaust.
Safe envelope verified: Starting surge (3200W) remains comfortably below the 13000W surge trip line, with steady-state operation settling into the safe continuous zone at 1050W.
About 21.3 hours on a full 8.3-gallon tank of gas, with the 1/2 HP well pump averaging 70 W: 1% of the DuroMax XP13000EH's 10,500 W rating. At this light load below the lowest tested point (50% load), fuel consumption interpolates between DuroMax's lowest published test load and Eco-Throttle idle fuel consumption. On propane (40 lb cylinder): about 16.2 hours.
Yes. The 1/2 HP well pump's start-up peak of about 3,200 W (up to 3,800 W) fits within the DuroMax XP13000EH's 13,000 W starting-watt rating, with 71% headroom even in the worst case.
Running a 1/2 HP well pump uses about 0.39 gal per hour at this 1% load, or 9.4 gal per day of use. A full 8.3 gal tank lasts about 21.3 hours. On propane: about 2.5 lb per hour, so a 40 lb cylinder lasts about 16.2 hours.
It's a conventional (non-inverter) generator; DuroMax rates its total harmonic distortion at 12% or less. It also shuts itself off if it detects a carbon-monoxide build-up. Run it outdoors only, well away from windows and doors.
