Hi Sir/Madam,

 

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

battery.

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

R.Rengasamy
