I have 2 - 100 watt Renogy panels I mounted on the roof of an RV with a 30 amp Wanderer controller.  I have the panels connected as shown on the diagram above. I am using a 125 Ah AGM battery. I want to add 2 flooded lead acid dual purpose 12v batteries, wired in parallel, via a battery selector switch. (B1, both, B2, off) I am aware I will have to change battery type depending on which bank is selected (never both) Am I able to configure this selector switch and old batteries into system? Any help appreciated. |

As long as you don't use "both" settings. And, being as you are using the Trimetric panel, make sure you install a shunt on the new batteries, just so if you add anything to them you are prepared.

Don't forget when you do switch the batteries with your devise, you need to go into the Trimetric panel and re-set your AH setting, and any others that may be required. Unless you are using the same type of batteries that is. Why didn't you use their solar controller, Trimetric that is? I have 600 w of solar (6 panels) and what I did was double up the controller, you can do that with theirs. I did leave my Renogy controller hooked up to the other trailer. I like the fact that you can hook it up to a computer.  |

The warning of disconnecting the panel before the battery may be bogus for PWM, don't know how to do that with that setup.
I'm sure switching from batt to batt disconnects the controller!!!!

Yes. I am concerned about no battery connection when switching form batt1 to off to batt2. I am beginning to think this is just a little too convoluted a plan - just to put an otherwise useless flooded cell battery to work and add a little amp hours. I hopefully didn't t fry the trimetric 2030. As of this writing no led display. Going to reside and start from scratch.

I have all working well currently. No pun intended. I had the trimetric wired in reverse. As it stands I will have to disconnect the solar inputs to the renogy pwm controller, then switch from batt 1 to batt 2, thru "off", then reconnect solar inputs to the pwm controller, then config the trimetric with new ah for batt 2. I will also have to change batt type on pwm controller to flooded. So, batt 2 is really just for emergencies and I should just go ahead and get another 125ah AGM battery and wire them in parallel and forget the switch. I should also spring for the SC 2030 controller as mentioned. I did not get that as i got the Wanderer with my renogy panels. Thanks for the feedback.

PS. I'll have to investigate the Wanderers computer connection features. TY.

I didn't know the Wanders had a computer connection? The Trimetric does. Perhaps I put the sentence in the wrong order above, I was thinking to fast.

If your charger has the option of setting all the charge voltage settings to your liking, you can just hook both batteries together, and chose the lower of the 2 voltage settings. I think you will find this to be more ideal than having to switch back and forth between 2 different batteries. Chose settings that are safe for both batteries, and you are good. Yes it is not as efficient as having both batteries the same, but the small loss of efficiency will not be as bad as the inconvenience of switching batteries back and forth.
