Please review Travel Trailer system wiring diagram

I am a new comer to this forum and a new comer to travel trailers. We recently purchased a brand new camplite 21rbs where i am in the act of setting up twin batteries, Inverter and Midnite KID solar with 4x100W flex panels. I’ve connected a system/wiring diagram regarding the the things I’m presently setting up and you will be powering up within the following day or 2.I would appreciate any feedback from the design to ensure a appropriate and SECURE system before We switch on!

Listed here is a hyperlink towards the diagram.

Thank you for responses.

Correct the 2000W inverter is large and is sized for operating microwave oven OR expresso device for some moments each.

Yes, how big the inverter may draw way too much whenever doing sitting idle and it is made to turn on/off effortlessly, Many Many Thanks!

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

Hi Mike,Thanks, you nailed my primary issue.

The Midnite Solar KID features a DC GFP that We have maybe maybe maybe not shown because I’m nevertheless looking to get some answers that are definitive just how to hookup battery pack negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup possessed a solitary battery pack negative linked to the framework nothing else. The energy center had all DC negative leads attached to a typical coach club that ended up being linked 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 battery pack negative from framework and then leave grounds to framework? Or float ground or another thing? I’ll be setting up 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 cell panels on a redneck ground mount; MNPV3 combiner feeds a MN Vintage 150 located 100′ away; 12V 460AH FLA battery pack bank capabilities 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 quick length, energy appliances that are hungry.

Fundamentally all grounds get to frame. Which includes AC ground from coast and all sorts of framework grounds of elements. Battery negative normally linked to framework. We included the DC-GPF from Midnite Solar into the last diagram (see express link). We setup tested and every thing worked fine today. Wire length arrived up in several reviews i had off their sources. Keep in mind that the “round journey" period of the 1/0 cable is not as much as 8 legs. from battery pack terminals to inverter and straight right right back.

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

With car lots, many utilize the framework whilst the return for energy (DC illumination, automotive radio, and such). In which you have actually the framework to battery pack ground now will “miss" any loads that occur to get back current through their framework ground connection(s).

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

1/0 cable is NEC ranked for

125 to 170 amps (in conduit)—And if perhaps you were likely to actually run the inverter near 2,000 watts for longer durations of that time period (lots of moments), I would personally be suggesting a 1.25 Wiring+Breaker derating (224 amps * 1.25 derating=)

280 Amp minimum rated Branch Circuit DC present.

If you are using the less conservative Marine standards that are wiring 1/0 is perfect for well over 285 Amps

That you do not 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 must have security for people connections too (fuses/breakers ranked to size of wiring).
