I am a new comer to this forum and a new comer to travel trailers. We recently bought a 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 following day or 2.I would appreciate any feedback in the design to make sure a appropriate and SECURE system before We switch on!
Let me reveal a hyperlink towards the diagram.
4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformerNight system
1kw panels into 1xMNClassic150 700ah 12v bank morningstar inverter that is 300w
Many thanks for responses.
Correct the inverter that is 2000W big and is sized for operating microwave oven OR expresso device for some mins each.
Yes, how big the inverter may draw way too much whenever doing sitting idle and it is built to turn on/off effortlessly, Many 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 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 We have perhaps perhaps 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 linked 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 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 the battery pack negative from framework and then leave grounds to framework? Or float ground or another thing? IвЂ™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 will trip while you state.
Right now IвЂ™m tilting towards disconnecting trailer framework from battery pack negative.

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. We 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 arrived up in a couple of reviews we had off their sources. Keep in mind that the trip that is”round period of the 1/0 cable is lower than 8 legs. from battery pack terminals to inverter and right straight back.
One small modification we will make is always to your battery pack bank grounding to your framework ground. I would suggest from the negative battery post to the common negative bus on the other side of the shunt that you move it.
With car loads, many make use of the framework once the return for power (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).
The battery pack bank is tiny for a 2,000 Watt @ 12 VDC inverter. Nominally, i might 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 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.
If you utilize the less conservative Marine standards that are wiring 1/0 is perfect for well over 285 Amps
That you don’t show breakers/fuses for a few associated with the wiring making the bus that is positive for a few associated with the other DC loads (hitch plug, cooling fan)–You must have security for anyone connections too (fuses/breakers ranked to measurements of wiring).
