We dont recommend that you charge at a rate more than 50 of your bank capacity. That will trigger the battery to battery charger and charge your house battery.
Dual Battery Setup In Van Conversion With Auto Relay Isolating Battery System
Sprinter house battery alternator charging system. I have a underhood aux battery already installed from factory. I am currently in the process of installing my solar system and would like to use the alternator to charge my house batteries when we are on the move. This is how vehicles charge their own 12 volt batteries and it is often how motorhome house batteries are charged. One of the most popular ways of charging a 12 volt battery is by using a vehicles alternator. This kit is ideal for van conversions and skoolies. I would like to save that battery for external lights on the vehicle and will have 2 seperate batteries for the house.
The battery will handle 100 amps of charging also but it will shorten the life span of the battery in our 2007 sprinter with stock alternator we typically see amps near the 100 amps mark into our solar batteries. Since this is well under the 50 mark of our 600 amp hour bank capacity we are safe. By doing so your batteries are constantly charging while you are driving and if youve been on the road for a while youre going to arrive at camp with a full charge no matter if its sunny or not. When the engine is off the charger will sense that the voltage has dropped below 14v alternator not running and will stop charging your house battery. Not for use with alternators not designed to deliver 150a to a secondary battery. An alternator works by converting mechanical energy into electrical energy.
The sprinter factory alternator provides up to about 100 ampshour when you are driving. A boost button lets your house batteries start your ignition when your starter battery is dead. Enable 200a alternator charging of a victron lithium battery system. When the engine is on and the alternator is running the aux battery relay will close and the aux battery will charge.
