Please review Travel Trailer system wiring diagram
I am not used to this forum and not used to travel trailers. We recently bought a brand new camplite 21rbs where i am along the way of setting up twin batteries, Inverter and Midnite KID solar with 4x100W flex panels. I’ve connected a system/wiring diagram of this the things I’m presently setting up and will also be powering up within the next day or 2.I would appreciate any feedback in the design to make sure a appropriate and SECURE system before We switch on!
The following is a web link towards the diagram.
Thank you for feedback.
Correct the inverter that is 2000W big and is sized for operating microwave oven OR expresso device for several minutes each.Yes, how big the inverter may draw an excessive amount of when performing 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 instances.i.e. all 1/0 cable lengths that are positive as much as 0 В· Share on Twitter

Hi Mike,Thanks, you nailed my main problem.
The Midnite Solar KID possesses DC GFP that i’ve maybe maybe not shown because IвЂ™m nevertheless hoping https://www.yourbrides.us to get some definitive responses about how exactly to hookup battery pack negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup possessed a battery that is single 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 along with AC ground. AC basic and ground aren’t bonded (by code only bond and that is done at coast energy panel). So my question is do I disconnect battery pack negative from framework and then leave grounds to framework? Or float ground or something different? IвЂ™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 must trip while you state.
Right now IвЂ™m tilting towards disconnecting trailer framework from battery pack negative.
1.2KW down grid system; 2 strings of 2ea 305W 60 mobile panels for 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 in addition to a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy times and a Champion 3800W generator for brief extent, energy appliances that are hungry.
Essentially all grounds go to frame. Which includes AC ground from coast and all sorts of framework grounds of elements. Battery negative is also attached 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 a reviews that are few had off their sources. Observe that the trip that is”round amount of the 1/0 cable is not as much as 8 foot. from battery pack terminals to inverter and straight back.
One correction that is minor will make would be to your battery pack bank grounding to your framework ground. I would recommend that you move it through the negative battery pack post into the typical negative coach on the reverse side associated with shunt.
With automobile lots, many utilize the framework whilst the return for power (DC illumination, automotive radio, and such). In which you have the chassis 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 AC that is continuous load. (2,000 watts * 1/0.85 AC inverter eff * 1/10.5 volt battery pack cutoff=) 224 Amp nominal flow that is current max 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.
If you utilize the less conservative Marine Wiring standards, 1/0 is perfect for up to 285 Amps
You may not show breakers/fuses for a few associated with the wiring making the good coach club for many associated with the other DC loads (hitch plug, cooling fan)–You needs to have security for all connections too (fuses/breakers ranked to size of wiring).
