I am a new comer to this forum and not used to travel trailers. We recently bought A camplite that is new 21rbs i am along the way of setting up dual batteries, Inverter and Midnite KID solar with 4x100W flex panels. I have connected a system/wiring diagram associated with the things I’m presently setting up and will also be powering up within the following day or 2.I would appreciate any feedback from the design to make sure an effective and SECURE system before We switch on!
Let me reveal a website link towards the diagram.
Thank you for commentary.
Correct the inverter that is 2000W big and is sized for operating microwave oven OR expresso device for some moments each.Yes, the dimensions of the inverter may draw an excessive amount of whenever doing sitting idle and it is made to turn on/off effortlessly, Thanks!
All breakers and wires sizes are to spec. This is true of energy center, solar and inverter. Wire lengths are brief 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 i’ve perhaps maybe not shown because IвЂ™m still hoping to get some definitive responses about just how to hookup battery pack negative (framework connect or otherwise not) and ground (chassis 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 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 frame? 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 will 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 cellular 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 in addition to a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy days and a Champion 3800W generator for quick extent, energy appliances that are hungry.
Essentially 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. I included the DC-GPF from Midnite Solar within the final diagram (see express link). We setup tested and every thing worked fine today. Wire length came up in a couple of reviews i had off their sources. Remember that the trip that is”round duration of the 1/0 cable is significantly less than 8 foot. from battery pack terminals to inverter and right straight back.
One small modification we would make would be to your battery pack bank grounding into the framework ground. I recommend that you move it through the negative battery pack post to your typical negative coach on the reverse side associated with the shunt.
With car lots, many make use of the framework given that return for power (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).
The battery bank is tiny for the 2,000 Watt @ 12 VDC inverter. Nominally, i’d 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 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 Wiring standards, 1/0 is perfect for up to 285 Amps
That you don’t show breakers/fuses for many regarding the wiring making the bus that is positive for a few associated with other DC loads (hitch plug, cooling fan)–You must have security for anyone connections too (fuses/breakers ranked to size of wiring).
