Mount the panels flat on the roof install a battery monitor so you can monitor the aux battery voltage without having to open something up install a battery isolator between your starting battery and aux battery to allow you to charge the aux battery from the vehicle alternator in the event the solar panels cannot keep up with demand.
Solar panel and alternator.
If so would i gladly spring for the extra 150 or 250 amp alternator.
Are you charging a battery bank or attempting to use t.
For simplicities sake think of it as power going from the alternator or the charge controller to the batteries but not the other direction.
Welcome to hurricane wind power wind generators and solar panel power systems.
I recently installed solar panels as you have described above.
Bhupender is basically correct.
I was told i need to turn off cut the solar panels when my sailboats engine and alternator are running otherwise i may blow the controller.
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.
This kit is ideal for van conversions and skoolies.
The charge controller should not be hooked up in line between the alternator and battery.
Every time i turn on the engine i am engage a cut off switch installed.
However that is the real question what are your requirements.
With an mppt controller almost any dc input voltage can be modified to meet your requirements.
Enable alternator charging to a drop in lithium battery bank.
We use 2 agm.
We add an extra step and hook an alternator switch between the solar batteries and the van batteries so with a flip of a switch the vans alternator can charge up the solar batteries.
Your solar panel s and charge controller are coming from an entirely different path.
Not for use with alternators rated less than 100a smart alternators or rigs with regenerative braking.
