Hi
Our company have already designed equipment with solar charger for a 12V SLA battery using the BQ24650 and 18V solar panel.
We have set the MPPT to 17.2V, and set the charge current to 1A using a 0.04ohm resistor between SRP and SRN.
One of our customer didn't want to use the solar panel, because he's got mains/wall power next to the equipment.
So my question is if we supply a 2A 18V or 24V DC power supply, the MPPT shouldn't be able to pull the voltage down to 17.2V right?
And also when battery is full, MPPT wouldn't try to get more current than the battery needs correct?
Cheers
Harry
