Alternator With A Solar Panel

Outside van estimated that in ideal sunny conditions my solar panels can pull up to 30 amps per hour.

Alternator with a solar panel.

Your solar panel s and charge controller are coming from an entirely different path. You can use car alternators to power a home. But the module cost makes up only about 33 percent of the total cost of building operating and maintaining a solar plant. Most rv s have a way of isolating the power coming from the alternator or another source like generator or solar charge controller.

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. An alternator works by converting mechanical energy into electrical energy. One method of doing this is to use the alternators to recharge storage batteries. Solar controller except for small trickle charge systems all solar systems should have a solar controller.

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. This setup helps to simplify the needed calculations for this type of power. Enable dc dc charging from your alternator to a secondary lithium agm or flooded battery bank. 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.

For simplicities sake think of it as power going from the alternator or the charge controller to the batteries but not the other direction. Example you have 300 watts of solar panels on your camper s roof and two 12 volt batteries. So far this 445 watt solar panel setup combined with the alternator has worked perfectly. This kit is ideal for van conversions and skoolies with older alternators or lithium batteries with input current limits under 100a.

These batteries could then be used to power an inverter which would produce the ac voltage needed to run the house.
