Please review Travel Trailer system wiring diagram
Azi in istorie
I am not used to this forum and a new comer to travel trailers. We recently bought A camplite that is new 21rbs 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 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 regarding the design to make sure a appropriate and SECURE system before We switch on!
The following is a website link to your diagram.
4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformerNight system
1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter
Many thanks for commentary.
Correct the 2000W inverter is big and is sized for operating microwave oven OR expresso device for some moments each.
Yes, how big is the inverter might draw way too much when performing sitting idle and it is made to turn on/off effortlessly, Many Thanks!
All breakers and cables sizes are to spec. This is true of energy center, solar and inverter. Wire lengths are brief runs in every 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 features a DC GFP that i’ve maybe maybe perhaps not shown because IвЂ™m nevertheless looking to get some definitive responses about just how 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 energy center had all DC negative leads linked 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 bond that is just that is done at coast energy panel). Therefore my question is do I disconnect the battery pack negative from frame and then leave grounds to framework? Or float ground or another thing? 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 will trip while you state.
Right now IвЂ™m tilting towards disconnecting trailer framework from battery pack negative.

Fundamentally all grounds get to frame. That features AC ground from coast and all sorts of framework grounds of components. Battery negative normally attached to framework. We included the DC-GPF from Midnite Solar when you look at the last diagram (see express link). We setup tested today and each thing worked fine. 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 significantly less than 8 legs. from battery pack terminals to inverter and straight right right right back.
One correction that is minor would make is to your battery pack bank grounding into the framework ground. I recommend that you move it through the negative battery pack post into the typical negative coach on the reverse side associated with shunt.
With car lots, many utilize the framework while the 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’d 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 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 minimum that is amp Branch Circuit DC present.
If you utilize 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 regarding the wiring making the good bus club for many regarding the other DC loads (hitch plug, cooling fan)–You need to have security for the people connections too (fuses/breakers ranked to size of wiring).
