![]() Mounting batteries in the passthrough will change how the battery switch is wired which is directly to the battery with no fuse or breaker. The 8 AWG circuits are no longer protected from the battery side so I connected a 30 amp auto reset breaker since the frame circuit is now being back fed. I left the wires on the frame, and connected both wires that ran to my battery switch to one side of the switch and ran a dedicated battery cable to the other side of the switch. I ran into this same dilemma that has been described in moving the batteries to the passthrough. Will Prowse's video on wiring and connectors has the best explanation I've come across. If they are-use multi-strand "welding" wires, not single strand. Consider installing larger gauge wires (largest the MPPT will accept) so if later more panels are added (and a larger MPPT is required) the wires are already in place.ģ) The wires coming from the MPPT to the bus bars appear to be solid core (one strand). ![]() As the other circuits that tie into the bus bar have their own protection this is probably just a preference, not a "must do".Ģ) A 20A MPPT does not require large wiring, but if your experience during the installation is anything like mine, routing and securing the wiring is not fun. Anything added (like the OEM wiring) to the bus bar bypasses the fuse. As configured in the picture, the fuse is only "seeing" the current coming from the inverter back to the battery (electron flow, i.e. Can you see anything glaringly wrong?A few thoughts based on what I see in the photograph.ġ) Consider moving the large 400A(?) fuse between the cutoff switch and the bus bar. I have attached a pic of my temporary setup. You are one of the latter and you do a great job here. 30 years of navigating the web and one knows how to separate the ones that give uninformed faulty info/guesses/opinions and those that are replying with informed info that's based on knowledge, research and real world experience Since you're a mod do you encourage separate posts for different questions to aid in people searching and to keep the replies on topic, rather than ask 16 questions in one thread?įrom reading this forum, I've been able to identify lots of good knowledgeable people that love to learn as they go and I hope to have their input on my quest. Everything was new to me.crimping, wiring and all so it was good practice.im going g to label everything and will post in future questions. Can you see anything glaringly wrong? I will probably upgrade the 2/0 to 4/0 cabling but I wanted to see if it worked. I didn't buy a inverter charger so I got to work with what I got. Figure out how to tie my system into the ac/DC main panel so all outlets work.Ĥ.figure out how to use my PD 5100 ATS to switch my OEM converter off when my inverter is on. Tie into trailer so I can lighten the load by about 60 lbs of interstate battery greatness.ģ. ![]() I successfully paired up shunt and controller and everything worked!!! I hadn't hooked up to trailer system, just a standalone type of test.Ģ. Yesterday I tried a test run on hooking up the batteries, solar panels, charge controller, inverter and bm712. I think I will do what you say and leave the wiring there underneath. It's funny I've been a PC hardware/software tech for 3 decades but have never had the necessity to learn all about ac/dc.Īnyways I have a 2018 imagine 2600 rb. It's kept me busy to go from layman to understanding what everything is and what it does. Throw in subscribing to 20 other solar and electrical Facebook pages and 100s of videos. There's plenty more, too-use the search function to find threads related to "inverter", "charger", "battery" and there's a lot to read!Īs far as reading and searching, I think I've read this whole forum/subforums and about 10 others. Other reading I encourage you to check out as many of the same questions you'll have are already addressed. When I installed my batteries in the passthru I ran a new wire to that original location on the 30A self-resetting circuit breaker.įor a look at my complete system (caution: may be overwhelming) see ![]() During my project that wire was removed and discarded. The positive that comes off the battery on my 315RLTS went a very short distance (looped under the front crossbeam immediately behind the "A" frame) and connected to a self-resetting 30A circuit breaker. To your specific question, I can't speak for "most people" but I can relate what I did. Which model of Imagine? There's several individuals with currently ongoing (or just completed) projects that own Imagines. What do most people do when relocating a battery bank? Do you run a positive from your bus bar in pass thru to the junction box and fuse or do you relocate all that wiring into your new location?First, welcome to Grand Design's Technical Forum. ![]()
