How Long Will a 200Ah Battery Run a 2000W Inverter?
A 200Ah battery can run a 2000W inverter for approximately 1 hour if fully charged and under ideal conditions. To calculate runtime, divide the battery capacity (in watt-hours) by the inverter’s wattage. A 200Ah battery at 12 volts provides 2400 watt-hours (200Ah x 12V), allowing for about 1.2 hours of operation, factoring in efficiency losses.

Calculating Runtime for a 200Ah Battery with a 2000W Inverter
To determine how long a 200Ah battery will run a 2000W inverter, you need to consider several factors, including voltage, efficiency, and actual load.
1. Understanding Battery Capacity
Battery capacity is measured in ampere-hours (Ah). A 200Ah battery means it can theoretically deliver 200 amps for one hour or any equivalent combination of current and time.
| Battery Capacity | Voltage (V) | Total Watt-Hours (Wh) |
|---|---|---|
| 200 Ah | 12V | 2400 Wh |
| 100 Ah | 12V | 1200 Wh |
| 50 Ah | 12V | 600 Wh |
2. Calculating Runtime
To calculate the runtime of the inverter:
- Convert the battery capacity to watt-hours:
- Total Wh=Capacity Ah ×Voltage V
- Divide the total watt-hours by the inverter’s wattage:
- Runtime hours =Total WhInverter Wattage
- Runtime=2400 Wh/2000 W=1.2 hours
3. Considering Efficiency Losses
In practice, you must account for efficiency losses due to heat and conversion inefficiencies in the inverter. A common efficiency rating is around 80-90%.
| Efficiency Rating | Adjusted Runtime (hours) |
|---|---|
| 80% | 1.2×0.8=0.96 |
| 90% | 1.2×0.9=1.08 |
Thus, under realistic conditions:
- At 80% efficiency, the runtime would be approximately 0.96 hours.
- At 90% efficiency, it would be around 1.08 hours.
FAQs
