I have two 100 Ah Renogy AGM batteries in my TT, connected to two Renogy 100 watts solar panels on the roof via a Renogy 30A PWM controller.
I want to install an inverter so I can use coffee maker and microwave. Quick napkin calculation showed I don't have enough power in the batteries to run the coffee maker and microwave in the morning before the sun had a chance to charge the batteries.
I want to install another battery but this time a 200Ah LiFe battery. Can the Renogy 30A PWM charger charge both the AGM batteries and LiFe battery at the same time? Multiple reason for the LiFe batteries: more useable capacity than AGM, longer life cycles. The AGM batteries are 4 years old and I think when I need to replace them, it'll be LiFe batteries.
I don't think I need add more solar panels since the two AGM batteries usually gets topped off by 10 AM. We have good amount of sunlight here in Colorado.
My best guess is I can not mix AGM and LiFe batteries in the same circuit to be charged by the controller. But I hope I'm wrong.
