Alternator With A Solar Panel

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

Alternator with a solar panel.

This kit is ideal for van conversions and skoolies with older alternators or lithium batteries with input current limits under 100a. An alternator works by converting mechanical energy into electrical energy. But the module cost makes up only about 33 percent of the total cost of building operating and maintaining a solar plant. Solar panel costs fell 53 percent in 2012.

For simplicities sake think of it as power going from the alternator or the charge controller to the batteries but not the other direction. So far this 445 watt solar panel setup combined with the alternator has worked perfectly. Your solar panel s and charge controller are coming from an entirely different path. Example you have 300 watts of solar panels on your camper s roof and two 12 volt batteries.

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. The charge controller should not be hooked up in line between the alternator and battery. Most rv s have a way of isolating the power coming from the alternator or another source like generator or solar charge controller. Enable dc dc charging from your alternator to a secondary lithium agm or flooded battery bank.

This setup helps to simplify the needed calculations for this type of power. 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. You can use car alternators to power a home.

One method of doing this is to use the alternators to recharge storage batteries.
