Critical Loads
▼
| Load Name | Watts (W) | Qty | Hrs/Day | Daily kWh | On? |
|---|
Motor loads (well pumps, fans) draw 3–6× their running wattage at startup. The 1.5× surge factor here is a conservative estimate — size up if you have large motor loads.

Existing Battery Bank (Optional)
▼
If you have a solar + battery system, your generator only needs to cover the shortfall and recharge batteries. Enter 0 for battery capacity if no battery bank exists.

Generator Sizing

80% Load Rule: Run generators at 50–80% of rated capacity for best efficiency, longevity, and to avoid wet-stacking (diesel). Avoid running at less than 30% load for extended periods.
