Please review Travel Trailer system wiring diagram

I am a new comer to this forum and a new comer to travel trailers. We recently bought A camplite that is new 21rbs i am in the act of setting up double batteries, Inverter and Midnite KID solar with 4x100W flex panels. We have connected a system/wiring diagram regarding the the things I’m presently setting up and will also be powering up within the following day or 2.I would appreciate any feedback regarding the design to make sure an effective and SECURE system before We switch on!

Listed here is a hyperlink to your diagram.

Remarks

Thank you for feedback.

Correct the inverter that is 2000W large and is sized for operating microwave oven OR expresso machine for some mins each.Yes, the dimensions of the inverter may draw way too much when doing sitting idle and it is built to turn on/off effortlessly, Many Thanks!

All breakers and cables sizes are to spec. This is true of power center, solar and inverter. Wire lengths are brief runs in every full instances.i.e. all 1/0 cable lengths that are positive as much as 0 В· Share on Twitter

1.2KW down grid system; 2 strings of 2ea 305W 60 mobile panels on a redneck ground mount; MNPV3 combiner feeds a MN Timeless 150 located 100′ away; 12V 460AH FLA battery bank capabilities a cabin-wide 12V DC system in addition to a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy times and a Champion 3800W generator for brief timeframe, energy appliances that are hungry.

Hi Mike,Thanks, you nailed my primary problem.

The Midnite Solar KID features a DC GFP that We have maybe maybe not shown because I’m nevertheless hoping to get some answers that are definitive just how to hookup battery negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup had a single battery pack negative attached to the framework nothing else. The ability center had all DC negative leads attached to a typical coach club that had been attached to the framework in addition to AC ground. AC basic and ground aren’t fused (by code only bond and that is done at coast energy panel). Therefore my question is do I disconnect the battery pack negative from framework and then leave grounds to framework? Or float ground or something different? I’ll be installing the GFP that connects between battery negative and ground and basically disconnects the PV+ during fault today. As shown now it will trip while you state.

Right now I’m tilting towards disconnecting trailer framework from battery pack negative.

1.2KW down grid system; 2 strings of 2ea 305W 60 mobile panels on a redneck ground mount; MNPV3 combiner feeds a MN Vintage 150 located 100′ away; 12V 460AH FLA battery pack bank abilities a cabin-wide 12V DC system along with a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy times and a Champion 3800W generator for brief period, energy appliances that are hungry.

Fundamentally all grounds get to frame. That features AC ground from coast and all sorts of framework grounds of elements. Battery negative normally attached to framework. We included the DC-GPF from Midnite Solar within the final diagram (see express link). We setup tested today and each thing worked fine. Wire length arrived up in several reviews we had off their sources. Keep in mind that the “round journey” duration of realmailorderbrides.com the 1/0 cable is significantly less than 8 legs. from battery pack terminals to inverter and straight straight right back.

One small modification we will make would be to your battery bank grounding to your framework ground. it is suggested from the negative battery post to the common negative bus on the other side of the shunt that you move it.

With automobile lots, many make use of the framework whilst the return for energy (DC illumination, automotive radio, and such). For which you have actually the framework to battery pack ground now will “miss” any loads that occur to get back present through their framework ground connection(s).

Battery pack bank is tiny for the 2,000 Watt @ 12 VDC inverter. Nominally, i might be suggesting a 500 Watt optimum constant AC load. (2,000 watts * 1/0.85 AC inverter eff * 1/10.5 volt battery pack cutoff=) 224 Amp nominal flow that is current maximum AC inverter score.

1/0 cable is NEC rated for

125 to 170 amps (in conduit)—And I would be suggesting a 1.25 Wiring+Breaker derating (224 amps * 1.25 derating= if you were going to really run the inverter near 2,000 watts for longer periods of times (more than a few minutes),)

280 Amp minimum rated Branch Circuit DC present.

If you are using the less conservative Marine Wiring standards, 1/0 is perfect for up to 285 Amps

That you don’t show breakers/fuses for a few associated with the wiring making the good coach club for many regarding the other DC loads (hitch plug, cooling fan)–You need to have security for anyone connections too (fuses/breakers ranked to size of wiring).
