To calculate the appropriate inverter size for a 48V battery system, you need to determine the total wattage of the devices you plan to power. The formula is: Inverter Size (Watts) = Total Load (Watts) / System Voltage (48V). This calculation ensures that the inverter can handle the required load without overloading.
Steps to Calculate Inverter Size
1. Determine Total Load
The first step is to calculate the total wattage of all devices you intend to power. This includes appliances, lights, and any other equipment.
| Device Type | Power Rating (Watts) | Quantity | Total Watts |
|---|---|---|---|
| LED Lights | 10 | 5 | 50 |
| Refrigerator | 150 | 1 | 150 |
| TV | 100 | 1 | 100 |
| Laptop | 60 | 2 | 120 |
| Total Load | 420 Watts |
2. Calculate Inverter Size
Once you have the total load, you can calculate the required inverter size using the formula mentioned earlier.Inverter Size (Watts) = Total Load (Watts) / System Voltage (48V)Using our example:Inverter Size = 420 Watts / 48V = 8.75 AmpsTo ensure efficiency and account for potential surges, it is advisable to choose an inverter rated at least 20-25% higher than your calculated requirement.
| Calculated Inverter Size | Recommended Inverter Size (Watts) |
|---|---|
| 420 Watts | 500 – 600 Watts |
3. Consider Surge Ratings
Some devices require additional power during startup (surge). Ensure that your selected inverter can handle these surges. For example, a refrigerator may require up to three times its running wattage during startup.
| Device Type | Running Watts | Surge Watts |
|---|---|---|
| Refrigerator | 150 | 450 |
| Total Surge Load | 450 Watts |
4. Finalize Your Inverter Selection
After calculating both running and surge loads, select an inverter that meets or exceeds these requirements.
| Inverter Type | Recommended Size (Watts) |
|---|---|
| Pure Sine Wave | 600 – 800 |
| Modified Sine Wave | 600 – 800 |

FAQs
How do I calculate what size inverter I need?
To calculate the size of the inverter you need, determine the total wattage of all devices you plan to power simultaneously. Add up their wattages, then choose an inverter with a capacity that exceeds this total by 20-30% for safe operation.
How do I match my battery size to my inverter?
Match your battery size to your inverter by ensuring the inverter’s input voltage aligns with your battery’s output voltage. Additionally, consider the battery’s amp-hour (Ah) rating to ensure it can support the inverter’s wattage for the desired duration.
How do you calculate battery inverter capacity?
To calculate battery inverter capacity, multiply the battery voltage (V) by the amp-hour (Ah) rating. For example, a 12V battery rated at 100Ah has a capacity of 1,200Wh (12V x 100Ah = 1,200Wh). This capacity indicates how long it can power an inverter at a specific wattage.
How many KW is a 48V 200Ah battery?
A 48V 200Ah battery has a capacity of 9.6 kWh. This is calculated by multiplying the voltage by the amp-hour rating: 48V x 200Ah = 9,600Wh, or 9.6 kWh.
