Ok.
Here goes.
I have solar panels wired up through a posh regulator thingy to my leisure battery bank.
I have the engine battery wired up to the alternator.
And I have a clever Sterling battery to battery charger. This is connected to the leisure battery(s) and the engine battery.
As I understand that the B2B charger detects the voltage in the leisure battery and the engine battery.
When you start up, the B2B can tell if the leisure battery needs any charging and proceeds to let the alternator do so once the engine battery has been fully charged.
If the leisure battery is full it just "floats"... letting a small current keep it topped up.
Ok... here is the query...
If the sun is shining the panels put a voltage around 14 volts across the leisure battery terminals. This is the voltage of the panels and is there even if the leisure battery is flat. So surely the B2B charger will read this voltage and "think" that the leisure battery is full and therefore not allow the alternator to pump in loads of amps and charge it up quickly.
Does my B2B only work to the maximum when it is dark?
JJ :Cool:
