i have a mppt 75/15 smart solar charge controller.
can i use it for charging two batteries at the same time or it works only for one?
how should i connect them to do so?
what are pros and cons?
in case i can't i have to buy another mppt and connect it to the battery, but then how can i switch the PV energy for the two mppt controller?
thanks
You can charge two batteries at once by connecting in parallel. They effectively become a single battery. Make sure both are fully charged before connecting.
If you need to keep the batteries separate, use an Orion DC:DC charger to charge one battery from the one being charged by the solar panels.
One controller can be connected to multiple panels.
Panels cannot be connected to multiple controllers.
hey sorry, i haven't seen your answer.
sorry also because i really didnt understand how to do. probably i didnt explain so well.
i would like to keep them separate because if one gets broken the other one can still work.
what about this?
