Alternator With A Solar Panel

An alternator works by converting mechanical energy into electrical energy.

Alternator with a solar panel.

These batteries could then be used to power an inverter which would produce the ac voltage needed to run the house. You can use car alternators to power a home. If you have two devices tied directly to the battery and each can provide a way to charge the battery at the same time you may end up with an overcharged battery or backfeeding one charging system with the other. The charge controller should not be hooked up in line between the alternator and battery.

Enable dc dc charging from your alternator to a secondary lithium agm or flooded battery bank. One method of doing this is to use the alternators to recharge storage batteries. Your solar panel s and charge controller are coming from an entirely different path. In two months we haven t had to plug in a single time and i haven t seen my battery voltage drop below 12 4 which is about 75 full.

Outside van estimated that in ideal sunny conditions my solar panels can pull up to 30 amps per hour. The purpose of a controller is to prevent batteries from being overcharged apply the optimal charging current to the battery bank and prevent current from back flowing from the batteries to the solar panel at night. But the module cost makes up only about 33 percent of the total cost of building operating and maintaining a solar plant. Example you have 300 watts of solar panels on your camper s roof and two 12 volt batteries.

This setup helps to simplify the needed calculations for this type of power. For simplicities sake think of it as power going from the alternator or the charge controller to the batteries but not the other direction. Solar panel costs fell 53 percent in 2012. In order to calculate this you just have to divide the watts provided by your solar panel by the number of volts in your battery bank.

Solar controller except for small trickle charge systems all solar systems should have a solar controller.
