We install this on top of our 2012 mercedes sprinter custom conversion van.
Alternator with a solar panel.
So if i didn t want any solar panels on the roof would i be able to consume about 50 amp hours per day from 300 amps of lithium batteries by just charging off a dedicated and separate alternator in a ford transit if i drive an average of 2 hours per day.
Car alternators and pv panels do not have similar characteristics.
As the name says it a solar charge controller is intended to be connected to a solar panel.
We add an extra step an.
Select an appropriate cyrix based on your house battery type and alternator current rating.
If so would i gladly spring for the extra 150 or 250 amp alternator.
Now i have an idea if i remove the alternator and replace it with solar panels would i get more gas mileage or gain.
Alternator 160a or less 120a cyrix alternator more than 160a 230a cyrix.
If you need a separate controller because you want to charge a li battery it is difficult to answer.
See how the combination of thermo king s thermolite solar panels and alternator power can be paired to maximize battery performance and reduce costly downtime.
Additionally when a charge is applied to a house battery bank the cyrix will close and allow current to flow to the starter battery.
