The engine will not start until the oil is at the proper level. | 10 |
| Overload | Lights when connected devices or a power surge exceed the generator's wattage or amperage capacity. The Output Ready LED turns off, the engine keeps running, and power to connected devices stops. | Remove all loads and stop the engine. Check for faulty or shorted connections. Restart the generator, then reconnect devices one at a time, letting it stabilize after each. Keep total connected wattage within the rated output power. | 10 |

FAQ
How long does the A-iPower SUA3800i run on a tank?
The maker rates it at 8.5 hours at 50 % load (about 1,750 W) on a 2.6-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the A-iPower SUA3800i start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 3800 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
