yep. Also if the second controller was MPPT that should be fine too. You just don't want two different types of solar modules feeding into one MPPT controller. Everything else should be OK.

The battery is a voltage source/sink so will establish the voltage that both controllers see. Depending on what each ones setpoints are one controller will cut out and/or in sooner than the other but that won't cause any issues. ]]> Thu, 08 Jul 2021 13:52:20 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143913#143913 solar panel use : So I just need to make sure... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143911#143911 Author: TheBum

So I just need to make sure that the portable system uses a PWM charge controller and that both are set to the same (correct) profile, correct? It makes sense that it should work if the controller output is open circuit during the off part of the PWM cycle.]]> Thu, 08 Jul 2021 13:43:45 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143911#143911 solar panel use : +1 to Colt.

+1 to Colt. No problem at all connecting two independent solar charge controller to the battery. Renogy is wrong if they are saying you need to run all your solar modules through one controller.

If you wanted to run a single controller with different solar module sizes or manufacturers that OK too as long as they are nominal 12V modules and you are using a PWM controller. Don't do it with an MPPT controller with modules of different voltages, you will waste energy and confuse the max power tracking software. ]]> Thu, 08 Jul 2021 13:01:31 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143910#143910 solar panel use : Originally posted by TheBumI'd... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143909#143909 Author: Colt

If you connect the 2nd system to the battery, each system will sense battery voltage and respond accordingly. I have had to connect a charger to my home solar system during extended bad weather, both with the panels/controller disconnected and connected with no trouble either way. ]]> Thu, 08 Jul 2021 12:46:06 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143909#143909 solar panel use : What Renology told me was that... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143905#143905 Author: TEDDY

What Renology told me was that the sum total of the parallel solar panels should be fed into a charge controller that can handle the total amps the panels can produce, and then you can clip the charge controller output to the battery terminals - they didn't mention it, but I suspect it would be safer to place and in-line fuse in the + wire between the battery clips and the charge controller.  Renology's 30 amp PWM Wanderer will handle my two 100 watt panels, and would probably handle a third.  The problem would be getting the panel wires into the charge controller - you might need special connectors for that, and for any extension wire used to get the panels in the sun.  If this would force you into a larger charge controller, you could disconnect the FR panels from the charge controller and connect the movable panels in their stead.]]> Thu, 08 Jul 2021 11:02:35 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143905#143905 solar panel use : I'd like to piggyback on... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143902#143902 Author: TheBum

Seems to me when I took out the board at the bottom of the WFCO converter/charger, the board was all I removed - it's at the bottom of the breaker/fuse array, and took maybe 4 screws and 4 wire connections to remove - just a board.

Amazon's description of the Progressive Dynamics suggests a much  bigger envelope that won't slip in to replace the WFCO board.  Will I have to accommodate the larger envelope somehow?

You should be good to go with the stock WFCO converter and an AGM battery. Where you would need to switch is if you were to go with an LiFePO4 battery. I made that change. That is because an AGM battery is still lead-acid chemistry, even if the acid is absorbed into a glass mat (thus, AGM).]]> Sat, 03 Jul 2021 16:56:12 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143787#143787 solar panel use : Any good controller these days... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143780#143780 Author: offgrid

It is pretty straightforward and relatively easy. The hardest part is getting the wires into the right places on the fuse board and then getting it back into place. Just pay attention to which wire goes where and then making sure you put the ones from the new converter in the right places.

I have done this twice. Once was to repair a broken converter. The second time was to change out the original board for one that would work with the LiFePO4 battery I installed. Yes, they are different as there are different charging profiles needed for lead-acid and LiFePO4 batteries. The WFCO boards are not programmable.I don't know about the Progress boards.

Thanks - I never asked the dealer about that port, and thought it might go to the WFCO charger - but wanted to make sure - and I would have been wrong!!

My WFCO converter has crapped out a few times - a friend and I found bad solder joints on the bottom of the board, fixed those, and it worked again - for a while - it's on the fritz again so I'll be replacing that board .  Any suggestions about what to replace it with?  It is the WFCO 55 series....

You can get any 12v solar kit with a charge controller. You don't need to get one that says Zamp on it or one from Renogy. You can if you want.

The port on the rpod is just a connector that will connect your solar charge controller output to the battery. The WFCO charger is not involved.

Be very careful connecting to it as the SAE type connector at the port has been wired in reverse polarity from normal. Use a voltmeter before connecting to be sure your polarity is right.

Or skip using the port and just connect your solar kit directly to the battery, you will have less wire resistance losses that way. Do add a bolt on or inline fuse at the battery + terminal before you connect there. A 20 amp fuse should be fine. ]]> Sat, 03 Jul 2021 05:29:36 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143764#143764 solar panel use : If you get something like the... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143761#143761 Author: StephenH

If you get something like the Renogy Solar Suitcase, it will come with a charge controller. The solar does not go through the converter. That is for 110V AC to 12V DC so yes, you will need that charge controller for your panel(s).]]> Fri, 02 Jul 2021 20:16:42 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143761#143761 solar panel use : That little plug I have on the... https://www.rpod-owners.com/forum_posts.asp?TID=14770&PID=143760#143760 Author: TEDDY
