Alternator With A Solar Panel

For simplicities sake think of it as power going from the alternator or the charge controller to the batteries but not the other direction.

Alternator with a solar panel.

Example you have 300 watts of solar panels on your camper s roof and two 12 volt batteries. 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. Your solar panel s and charge controller are coming from an entirely different path. An alternator works by converting mechanical energy into electrical energy.

You can use car alternators to power a home. Most rv s have a way of isolating the power coming from the alternator or another source like generator or solar charge controller. Solar panel costs fell 53 percent in 2012. So far this 445 watt solar panel setup combined with the alternator has worked perfectly.

One method of doing this is to use the alternators to recharge storage batteries. These batteries could then be used to power an inverter which would produce the ac voltage needed to run the house. 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. But the module cost makes up only about 33 percent of the total cost of building operating and maintaining a solar plant.

This setup helps to simplify the needed calculations for this type of power. This kit is ideal for van conversions and skoolies with older alternators or lithium batteries with input current limits under 100a. Solar controller except for small trickle charge systems all solar systems should have a solar controller. Outside van estimated that in ideal sunny conditions my solar panels can pull up to 30 amps per hour.

Enable dc dc charging from your alternator to a secondary lithium agm or flooded battery bank.
