We are Used LT8490 MPPT charger for one of our project.
Our idea is to charge two 12V/100Ah SLA batteries from two 40w solar panels
connected in parallel (OCV = 27V)
We have added load switch between charger and batteries.So that in long
cloudy days we can charge only selected battery.
Secondly in case any one of the battery becom faulty during the service
period disconnect from charger through micro controller
who moniter battery health though gauge IC (LTC2943)
Load sharing switch (LTC4416) used to discharge power from healthiest
incase both SLA battery levels fall below 11V load will be supply thorough
Backup supply Li-Ion Battery.
Kindly tell me this schematic which I have attached will work as per above
listed requirement or not ?
Thanks & Regards
We are Using LT8490 MPPT charger.
We are facing one problem,
we are powering the charger IC Through DC Regulated power supply (VINR pin pulled low) Battery is charging and status LED shows the corresponding charging stage
If the DC supply switched off at that time also status LED blinking
I have measured the below voltage when DC supply switched off
Voltage in Vin Pin shows 6.3V
AVDD Pin shoes 3.3V
Can you give me some solution ?
Sorry, there is not enough information.
