Solar hook up to rv


The night sky darker than you have ever seen, the stars brighter, the moon looking larger than it does from the city. The smell of baked earth and eucalyptus on the warm night wind.

After all, you can never get fully off-grid if you need to load up on generator fuel twice a week. It can feel daunting to get started with solar power. How many panels do you need? Will you need to rewire the whole rig? This article will give a brief overview of the basics of solar energy.

AC and DC – what’s...

They do not directly power your electrical equipment — they charge the battery. There are two equally important halves to a solar rig: The solar panels charge the battery, aided by a charge controller which regulates the flow of current.

Amps measure current, watts measure the rate at which power is used, and volts measure the difference in charge between two points in the system. Think of your battery as a sink being filled from a faucet.

Amps are the water that flows through the faucet and collects in the sink; volts are the pressure in the pipe which pumps the water out; the watts used by your household goods are like the plughole which lets Solar hook up to rv water run out. The words AC and DC stand for alternating current and direct current. Equipment which runs on AC is usually energy-hungry, because mains power is plentiful at home. This is the type of electricity you get from a battery.

Staying in an RV, you might get by on just a trickle of electricity, or you might use even more than you do at home. It all depends on your lifestyle. Before choosing solar panels, calculate how much Solar hook up to rv you use in a day. The energy consumption of DC electrical equipment is rated in amp-hours — this is, as the name suggests, a measure of how many amps they will use in a single hour. The capacity of your battery is also measured in amp-hours Ahwith most RV batteries around Ah.

A battery rated 72Ah will be able to power a 1Ah light for 72 hours, or a 12Ah water pump for 6 hours. AC electrical usage is usually measured in watt-hours Wh, usually shortened incorrectly to just watts, Wand the watt-hour ratings can usually be seen on the plug casings.

How do solar panels work?

Amps are just watts divided by voltage; in a 12V RV system, you can divide the watt-hour rating of your equipment by 12 to see how many amp-hours it will draw down from the battery. To calculate the total electricity you use in one day, multiply the amp-hours of each piece of equipment by the number of hours you use it. Add up the amp-hours for all your equipment to estimate your total daily power usage, rounding your answer up to cover any power loss within the system.
