From powering RVs to optimizing boats’ electrical grids - by learning more about what are watts, volts, amps and ohms, you can make informed decisions regarding any power requirements in your application.

Key Takeaways

• Understanding Watts requires knowledge of volts and amps, which are essential for RV & boat power calculations.
• Appliance labels provide wattage information to inform decisions about optimized power consumption.
• The formula P (Power) = I (Current) x V (Voltage) is crucial for doing any calculations about how much power you want or need in your power system.

What Are Watts: Understanding the Basics

Watts are the unit of measurement to describe power, or the amount of energy consumed or passed through an electrical circuit as it provides the ability to do some function. Most commonly, you’ve likely heard or read about watt ratings for various appliances such as microwaves, radios and other electronic devices.

To understand this better, consider an analogy that compares electrical power to water flow using the equation P (Power, measured in watts) = I (Current, measured in amps) x V (Voltage, measured in volts).

P = I x V

In this water analogy, imagine that water is being allowed to flow through a water hose. The flow of water itself is the current (measured in amps). And the rate at which it is being pushed through the hose is the voltage (measured in volts).

Thus changing either the rate of flow or the force by which the water is pushed through the hose (water pressure) will change the force by which the water is able to do some kind of work when it leaves the house. Such work could be pressure washing a driveway or it could be providing water to a sink or shower head.

So the idea of work, or power, is a function of current times voltage (or amps x volts). And changing either, or, or both of these can have a significant impact on the ability for the electrical flow to do some kind of work (ie - water pressure) .

In electrical terms, voltage represents how much potential difference there exists between two points, while current tells us about its flow rate. When these quantities are multiplied together, you get Watts, which measures electricity's overall power capacity that has been delivered from one point to another.

Thus, both volts and amps (the basic units) form part of calculating wattage where one amp travels along with 1-volt force across any given electrical circuit allowing for work done according to total output strength.

Now, let’s look at this concept from the other side of the equation. Let’s say that there is some appliance that requires X amount of water pressure in order to function properly.

In order to provide enough water flowing to the appliance, you will have to change either the force at which you push the water (voltage) or the amount of water that is permitted to flow through the hose (current).

If the appliance does not receive enough of this force, then it will not be able to function.

Let’s return back to the concept of electrical power. Understanding that certain devices require a certain amount of electrical force to function gives us a clearer understanding of what watts are and the importance that they play.

For example: The average microwave requires around 1000 watts of power flow in order to operate. If the device doesn’t receive that much power, then it will not turn on.

Or take the popular Minn Kota Endura Max trolling motor with 40 lb thrust. On a 12 volt power system at full speed, the trolling motor will draw a current of 35 amps. Referring back to the equation: P = I x V

P = 35 amps x 12 volts = 420 watts

If the battery supplying the power to the trolling motor does not have the capacity to provide 420 watts to the trolling motor then the motor simply won’t turn on.

You’ve likely experienced this in more common experiences with dead batteries in flashlights and smoke alarms.

Thus the idea of understanding that watts are a measurement of the amount of power required to run certain devices is crucial in planning an electrical circuit capable of powering your RV or boating needs.

Everyday Examples of Watts in Action

Powering your home appliances, keeping an RV or boat running, and other daily activities all require a significant amount of watts. To optimize their electrical systems properly, it is important to have insight into the wattage needed for these different scenarios.

Understanding how much power air conditioning units need as well as lighting fixtures, heating equipment, and water heaters along with TV/media devices can assist in making informed decisions regarding energy use accordingly.

Why do watts matter for RVs

When it comes to RVs, calculating your required electrical power is essential. The amount of wattage needed for all appliances and lights must be determined in order to choose the right amount of battery bank or alternative power source to provide enough electric current throughout the electric circuit.

The calculations can get quite complicated, particularly when trying to determine exact power consumption of each device over an anticipated amount of time of use of each. However, if you want to properly size your house battery bank or want to plan for how much solar you should add to your RV, then you will want to be as precise as possible.

For example, you may have an air conditioning unit that requires 3,500 watts of power to start up (though it may run on significantly less). This means that in order to use the air conditioning you will have to have 3,500 watts of power times the amount of time you want to run it stored somewhere (or you will only be able to use it when you are connected to shore power or a generator).

Or you may wonder whether or not you can run your favorite coffee pot from home while you are out on the road in your RV. If you do not have the right amount of power stored in your batteries then you will not be able to use the device when traveling.

Further, replenishing any power you’ve consumed from your battery bank by way of solar panels can be calculated so that you have enough solar panels that are able to capture enough wattage to be able to recharge your batteries for future use.

Understanding watts, being able to find watt ratings on common RV electrical appliances and being able to do basic calculations to determine your total power needs is incredibly important so that there's ample power while on-the-go, maximizing comfort during your journey!

How to Measure Watts - Watt Hours Explained

When measuring power, watt-hours are used to calculate the amount of energy expended over a given time period. This unit is useful for understanding how much electricity appliances consume in relation to their use.

To figure out the number of watts consumed by an item, you simply multiply its power (in watts) with the length of its operation (measured in hours).

For example, a 100-watt light bulb left on 10 hours would be using up 1000 watt-hours worth of energy. Simply multiply the amount of watts that it requires for one hour (100 watt rating) times the amount of time that it will be on (10 hours): 100 watts x 10 hrs = 1,000 watt-hours.

Further, watts and watt hours can be considerable when calculated. So a common way to address larger watts or watt hours is to use the term kilowatt or kilowatt-hours.

A kilowatt is the total wattage divided by 1,000. Thus in the example above, the 100 watt light bulb left on for 10 hours will consumer 1,000 watts or 1kW (1,000 watts / 1000).

Knowing this information can help people make more informed decisions when it comes to managing electrical consumption and usage habits within households.

How to Read Appliance Labels for Wattage

Calculating how much power an appliance will draw can be determined by its wattage, which is usually listed on the bottom or back of the device or nameplate.

If this information isn't available, you can estimate it by multiplying electrical current (in amps) and voltage to get a near exact idea about your consumption levels and determine if your electrical system supports these appliances sufficiently.

With proper calculations, important decisions around energy utilization can be made accurately.

Check out this post to help get an idea of how much wattage you may use in your electrical setup.

Using Watts to Plan a Solar Panel System

One of the most important things you can do with knowledge of watts and how important they are to RV and marine applications is in planning a robust solar system. To do this, you’ll need to refer to the steps above and/or use a power consumption calculator to get a rough estimate of your daily power consumption.

First, list every appliance that you think you will use at any point in any given day. Be sure to list the big appliances, such as air conditioners and microwaves, as well as smaller ones such as LED lights and vent fans.

Search for the wattage for each device and then multiply the wattage of the device by the time in hours that you expect to use it.

For example, a light that uses 1 watt that you plan to use for 6 hours will require 1 watt x 6 hrs = 6 watt-hours of power. Add this to your other appliance calculations to determine the total amount of watt-hours that you think you will use on any given day.

Then research the solar panels that you plan to install. The average 100 Watt solar panel has the capacity of generating approximately 500 watt hours of solar power per day. There are a lot of variables that will impact how much power you can actually collect - such as shade, season and latitude.

But in general, you could get an idea of the amount of power consumed each day and add solar panels to capture more power than you could possibly need so that you worried less about your power and more about enjoying the benefits that solar panels provide!
