The most basic electrical formula there is: Volts x Amps = Watts.

## Basic Formulas for Measuring Watts vs Amps vs Volts

Watts is a measurement of how much power something uses in the terms of voltage and current (Amps). Amps measures current. If you compare electricity to water flowing in a pipe, voltage is the amount of pressure while amperes is the amount of volume. An object does not run on current alone or for that matter, voltage alone. An object requires both voltage and current (Amps). The amount of power an object produces varies. So that is where Watts come in.

To Calculate Watts vs Amps vs Volts you will need the basic formulas.

Watts x 1000 = kilowatts (Kwh)~ the measurment used by your Utility company. They charge in Kilowatts which is watts x 1000 = a kilowatt

Volts x Amps = Watts

Watts divided by Volts = Amps

You will need 2 numbers to figure the amount of current.

You need to configure this to determine the size of wiring to connect your batteries, solar array as well as wiring to the gird.

**Use the following formula for all electrical devices~**

Watts of device x 24 hours per day = Daily Watt Usage.

Daily Watt Usage x # of days in month = Monthly Watt Usage.

Watts divided by 1,000 = Kilowatts.

Kilowatts x the Kilowatt rate charged by the power company = the Monthly Operation Cost of that Device~

An inappropriate size on any component will diminish the production of your components. Size does matter.

There is one area that it is important to understand the difference between Watts vs Amps vs Volts and that is the area of solar energy. If you were to implement a system of PV solar panels, you would need to calculate the amount of wattage your household uses in order to figure the number of panels you would require.

I have 4 225 ah agm batteries, 6 volt.

My solar panels are 2 250 watt canadian solar 24 volts

If I do a serial set up on the batteries and a parallel wiring of the panels, will I have enough to power a freezer that uses a bit under 1000 watts per day?

Is the the best way to wire this setup?

Any comments on doing a serial – parallel on the battery bank?

Thanks!

Thanks for finally talking about Calculating Watts vs Amps

vs Volts for a PV Solar System. Liked it!

Hello there! This is my first visit to your blog! We are a team

of volunteers and starting a new project in a community in the same niche.

Your blog provided us useful information to work on.

You have done a wonderful job!

This is a interesting article by the way. I am going to go ahead and save this article for my sis to read later on tomorrow. Keep up the first-rate work.

As I website possessor I conceive the subject matter here is very excellent , thank you for your efforts.

We just couldn’t leave your website before saying that we really enjoyed the useful information you offer to your visitors. We’ll be back soon to check up on new stuff you post!

Keep up the nice work on the site. I love it.

Id just like to tell you how much I learned from reading your articles. Hope to be back again for some more

This is some good material. It took me a while to come across this website but it was worth the time. I noticed this page was hidden in yahoo and not the first spot. This blog has a lot of high-quality material and it does not deserve to be burried in

This is really interesting, You are a very skilled blogger. I’ve joined your rss feed and look forward to more of your fantastic post. Additionally, I have shared your website in my social networks!

Hey this is a great post . Can I use a portion of it on my site ? I would obviously link back to your page so people could view the complete post if they wanted to. Thanks either way.

Great post, there is most useful information for me, thank you.

I believe you have mentioned some very interesting details , appreciate it for the post.

That is really a nice post. If you notice I do not edit out bad comments (except foul language). I tire of these no-it-alls that screen all their comments. Thanks for the comment and feel free to share my page with whom you see fit. Best regards, John

I’m planning buy a battery 13 volts the plant is to use 20 watts for 2 hours how big should i buy the battery ? any suggestion thanks.

I need more info, but on what you gave me I would recommend something rated at about 80 watt hours minimum. A Mid sized motorcycle battery should do fine. For numerous recharges I would go with a lithium or other high dollar battery. A good R/C tech at a hobby shop could probably help you out quite a bit. Again, I really need more data for any meaningful recommendation.

This will help me on my high school finals!

Thanks, there are also numerous other formulas. Feel free to share with friends.
