What Size Charge Controller for Generator--->RV Battery?

We Answered:

Charge controllers that are meant for Solar charging are significantly different to Battery Chargers meant to be used on AC. I suggest using an Automatic battery charger and adding a Solar charger controller at a later date.

Since you won't want to be running your generator for many hours, get a reasonably beefy one. e.g. if you were to base the charge rate on the C/20 rate your 115 A/h battery would take 20 hours to charge at 5.7 Amps (+ a bit to allow for conversion efficiency) (assuming full discharge, which you don't want).
