hi youtubers jeff cote here with ask pys so we're going to go down the rabbit hole on this one a little bit and we've got a question from jake a fellow voter okay so jake asks assuming your engine and house battery banks are both the same size in this instance 105 amp hours which i would guess is probably a group 20 27 or 31 it would be 31. would there be any way to hook up a single solar panel to charge both or do i have to select one and put a battery selector switch to both to do that okay so great question from jake um there are solar controllers by the way that output like the solar controller itself has two outputs we don't normally use that and they're not that all that common but they do exist and if any users on youtube have experience with actually a solar controller that connects to two battery banks share down below and let me know how your experiences are normally normally i'd say 98 99 of all our installs have a single single solar controller and this single controller with single output is meant to go to one battery bank so when we decide which battery bank should get a charge we figure out which one is going to be used the most which one is going to be deep cycle and that's where we connect the solar controller so the panel connects to here and this connects to the battery now here's the key if you want to share this device to another battery bank then what i would suggest you do is you actually put in what's called an echo charge it's a small battery combiner that is directional so it allows current to go only one way and not the other way and it would have your house battery share a charging voltage with the engine battery via a echo charge xantrax makes that and it's a directional battery combiner and it's a way for you to make sure that not only your house battery bank but also your engine battery bank gets a charge from one single solar panel and one single controller so that was a really good interesting question from jake thanks for watching this video if you've got further questions that we didn't answer please ask them below or go on our website and fill out one of the forms and lastly if you haven't subscribed to our channel please do so that way you'll get the regular contents and in closing thanks for watching
