Calculate the total power consumption of your appliances

To find out how big of an inverter you need, start by figuring out how much power your devices use. This helps to match the inverter size to your power needs. Here’s how to calculate it:

  1. List all the electronic devices that you will power with the solar system. Include things like lights, refrigerators, and laptops.
  2. Check the wattage on each device, usually found on a label or in the manual. Write down these numbers.
  3. Determine how many hours per day you use each device. Be realistic about daily usage for accuracy.
  4. Multiply each device’s wattage by its daily hours of use. This will give you the watt-hours (Wh) per day for each one.
  5. Add up all the watt – hours from every device to get your total daily consumption.
  6. Consider extra power for starting appliances like air conditioners or refrigerators as they need more watts at startup.

Sizing the inverter

You need the right size inverter to get the most from your solar panel. Choosing one that’s too small or too big can cause problems.

  • Check your appliance needs. Add up the power ratings of all devices you want to run at once.
  • Look at continuous power. This shows how much power an inverter gives over time. Most appliances list their wattage.
  • Consider peak power. Many devices need more energy when they first start, like refrigerators and tools.
  • Go a bit higher than your total appliance watts. This gives you extra space in case you get more devices or if one uses more power than expected.
  • Don’t forget efficiency loss. Inverters can lose a bit of power as they change DC (direct current) from solar panels to AC (alternating current).
  • Think about future needs too. You might add more solar panels later or buy devices that use more energy.
  • Choose a pure sine wave inverter for sensitive electronics like laptops or TVs. They work better with this type of inverter.

Best Inverter Options for a 200W Solar Panel
