Please review Travel Trailer system wiring diagram

I am a new comer to this forum and not used to travel trailers. We recently bought a brand new camplite 21rbs where i am in the act of setting up double batteries, Inverter and Midnite KID solar with 4x100W flex panels. I’ve connected a system/wiring diagram of this the thing 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!

The following is a hyperlink to your diagram.

1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter

Many thanks for remarks.

Correct the 2000W inverter is big and is sized for operating microwave oven OR expresso machine for several minutes each.

Yes, how big the inverter may draw a lot of 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 energy center, inverter and solar. Wire lengths are quick runs in every full situations.i.e. all 1/0 cable lengths that are positive as much as 0 В· Share on Twitter

Hi Mike,Thanks, you nailed my primary problem.

The Midnite Solar KID possesses DC GFP that We have maybe perhaps perhaps not shown because I’m nevertheless hoping to get some answers that are definitive just how to hookup battery pack negative (framework amino connect or otherwise not) and ground (framework connect or otherwise not). The factory setup possessed a solitary battery pack negative attached to the framework nothing else. The energy center had all DC negative leads linked to a typical coach club that had been linked to the framework in addition to AC ground. AC neutral and ground aren’t fused (by code bond that is just 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 today that connects between battery pack negative and ground and basically disconnects the PV+ during fault. As shown now it must 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 cellular panels for 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 in addition to a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy times and a Champion 3800W generator for quick extent, power 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 last diagram (see express link). We system tested today and each thing worked fine. Wire length arrived up in a couple of reviews i had off their sources. Keep in mind that the “round journey” period of the 1/0 cable is lower than 8 foot. from battery pack terminals to inverter and right straight back.

One small modification we will make would be to your battery pack bank grounding to your framework ground. I recommend that you move it through the negative battery pack post to your typical negative coach on the other hand associated with shunt.

With automobile lots, many make use of the framework given that return for energy (DC illumination, automotive radio, and such). Where 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 little for the 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 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 minimum that is amp Branch Circuit DC present.

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

You don’t show breakers/fuses for a few for the wiring making the good coach bar for many for the other DC loads (hitch plug, cooling fan)–You needs to have security for everyone connections too (fuses/breakers ranked to measurements of wiring).
