Hello,
I'm looking at installing a 100w kit on my off-road/adventure vehicle. Being a complete novice to solar I'm wondering if there would be a problem to running solar full time to my single battery (used for both starting and as house), mostly concerned if there will be some problem with the alternator on the same circuit.
Also will the "wanderer" charge controller be a good fit in this scenario?
Thank you in advance!

The concern is using one battery not designed to be discharge very deep as a house battery.
Starting batteries are different than batteries that are designed to be discharged.
noting that, there is no issue with multiple charging sources of a battery. Just don't do it, you'll get stranded, get a separate battery

Rapid answer is wise. I have an off road vehicle, I have a separate set up on it as you do, however, I have two batteries one for chassis one for "other uses" The controller charges the "other battery", but there is a switch, that see's both batteries and will automatically charge both or one when needed, but when it sees the chassis battery as being charged it cuts that one out. It's called a "BIRD" Bi-Directional Isolator Relay Delay. it performs two important functions.It provides a method of charging the "engine battery" from the engine alternator and charges the other battery from the converter when my jeep is plugged into shore power or just using solar. When neither battery is being charged, the batteries are isolated from each other to prevent the loads of one battery from inadvertently discharging the other battery. This works in combination with a continuous duty solenoid to connect the two batteries at the proper times for charging.
