Hello Pan57
In the process of installing one and a 100ah BB battery. Solar side done need to run new cable from truck alternator back to dc-dc charger. Our iota 12 volt power supply and charger will not meet the needs of the lithium battery. Need to ask renogy if isolating the battery from the circuit and plugging into 120V would or could damage the dc-dc charge controller. The iota is good to function as a power source according to them(iota). My thought is the solar 250 watts and truck alternator will be enough. Our load items are refrigerator, fans, led lights, and usb devices. We’re excited to see how it all comes together. Good luck with your project.

Do you have the new smart alternator style or a conventional charging system?
A while back a member had charging issue and I think the Toyota truck alternator wouldn’t provide enough power even after driving all day.
