Watt, Amp, and Volt? Why Do You Need To Know them?

Getting and installing a basic solar power shed is not the last thing. The reality you will face when you want to use some heavy appliances. Maybe the shed can’t provide such power.

So, you need more power. But how did you miscalculate the power? That’s why you need to get some electrical knowledge. There are three things you need to know and these are to find out how many watts you need.

  1. Watts
  2. Amps
  3. Volts

Watts defines the unit used to measure electrical power. Amps are for electrical flow rate (current). Last, Volts defines power (pressure). That means more or higher voltage for more electrical current flows.

Let’s Find Out how watts are measured in terms of Voltage and amps. It has the formula to find the exact figure and that is.

Watts = Voltage * amps

For the small appliance, you can use a 160-watt solar panel. If needed, use two of them. Along with that, use a 200 AH battery. You also need an amp regulator and watt inverter. With this setup, some appliances can be used easily and some are not.

If you are using a 600-watt inverter with this 160-watt setup that means you can’t use an appliance over 600 watts. Because the inverter has the capacity to handle power under 600 watts.

Using a 20 amp regulator never lets you use an appliance that burns more amps than it can deal. One more thing, you also need to count and it’s the power of the battery. It also has the limitation to store power.

To keep the battery healthy perfect you can’t use all of its capacity. When the shed is not getting the sunlight, don’t use all the power of the batter. Because it will run down fast. With 160 watts of power, it’s easy to use different types of small appliances, especially those which are under 50 watts.
