Solar Panels To Run A 6 5 Amp Refrigerator

For example a fridge may read 115 volts and 4 5 amps of current.

Solar panels to run a 6 5 amp refrigerator.

Which when you consider the solar setup draws about 5 amps per hour total we have a decent amount of amps per hour leftover to do with what we please. Residential refrigerator 8 5 amps 115 volts 60 hz. Roughly our fridge draws 1 3 amps per hour. The solar panels have to be connected to a battery and inverter to provide power to your fridge.

Fridge draws 6 amps you multiply 6 by 120 volts to get 600 watts. At night there will be no power for the fridge and it will shut off. Multiply these two quantities to calculate its power demand. 115 x 4 5 517 5 watts of power.

For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts. If amps are given convert amps to watts by multiplying the amps times the voltage. Always round this off to the higher number. For this system you would need seven 75 watt solar panels and four 300 amp hour batteries.

So we used a whole bunch of confusing math and figured everything out. However with the right solar power configuration and power requirement calculations you should be able to run any refrigerator with solar power. Thus the output for each solar panel in your array would. The coach and chassis electrical systems on our coach are completely separate.

We currently have 300 watts of solar panels on the roof. Really the question should be how much power do i need to power a refrigerator. No phantom loads in rv in reality there are many phantom loads that use up battery power 18 cu. For instance if your typical 16 cu.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. An inverter is a device that turns the power from a 12 volt dc battery like the one in your car or truck into the 120 volt ac power that runs all of the electronics in your house. How much energy does a solar panel produce. Because you can t power a fridge on solar panels alone.

You can use one of these devices to power all sorts of devices in your car but it s important to figure out how big of an inverter you need first. The refrigerator is rated at 8 5 amps x 115 volts 977 5. These are run through the factory installed combiner and are integrated through a 40 amp solar charge controller from zamp. 5 hours sunlight per day for san diego number used in solar calculations full sun no shading no clouds zero days of autonomy.

Calculate the current in amps by dividing power in watts by the voltage in volts. Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels. For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. We started off with one 100 watt panel.
