  • Presentation Materials for Solar-101 Discussion at the 2019 Elkhart National Rally

    Moderator Note: There is an updated version of Jim's presentation in the Solar > Reference Material channel: https://gdrvowners.com/forum/solar/r...4-solar-101-v4 -Howard

    ----------------------------------------------------------------------------------------------------------------------------------------------

    I will be hosting a seminar at the national rally in a couple of weeks. The topic will be an introduction to RV Solar charging systems. I'm attaching the presentation to this thread. It is not fully self explanatory. It is talking points for the presentation. If you have any questions, please ask.

    Jim - I look forward to attending your presentation. Your pdf does a great job of detailing all the aspects. More complex than I thought. Total recommended average system costs, life span, maintenance, etc, will be interesting to learn as well.

          I made several changes based on recommendations that several of you sent me in private messages. I removed the first version and posted a new version in the first post on this thread.

          Thanks much,

          Jim

              Excellent material Jim.

              And it was a pleasure meeting you and Ginnie at the Rally.

                Excellent seminar, we learned a lot. I have a question about wiring the panels in series or parallel. We are looking to install 4- 200 watt panels.Wiring in series would give me 48VDC smaller wires to run, but I would want to keep the batteries wired in parallel to supply 12VDC to the coach. Is there a solar controller that takes 48VDC from the panels but outputs 12VDC? Also looking to install the Magnum Energy MSH3012M, Hybrid Inverter charger. It looks like it will act as a transfer switch and will add battery power if we don't have enough pedestal of generator power.

                  An appropriately sized MPPT controller will handle that reduction just fine. It will reduce the voltage and bump up the current an equivalent amount. This is very desirable.

                  Those are some very powerful panels. If you can provide the specifications on the panels, I can recommend a controller that can handle them.

                    I did six 200 watt panels in mine. I did a mix of series and parallel to keep the wire size manageable. I did three pairs of two series panels. I went with the Victron 150/100 charge controller so I would have some room to add more panels down the road if I wanted. It has no problem with the additional voltage coming out of the panels series/parallel combination, and converts that extra voltage into charge current.

                    Jim, sorry I missed your solar presentation, our little guy was mid nap and I could not get away. I am sure it was great!

                        I will be presenting the "Solar 101" pitch this week at the Southern California rally. I've updated the charts that are linked in the first post on this thread.

                          Great information. We are in the process of ordering our solar system to install 400Watts of panels to charge 200amps of Lithium batteries with a standalone 2000 Watt inverter on our 2020 Imagine XLS. Any words of wisdom are appreciated. Am excited to know that Grand Design is embracing solar installations.
