I am not used to this forum and a new comer to travel trailers. We recently bought a new camplite 21rbs where I’m along the way of setting up double batteries, Inverter and Midnite KID solar with 4x100W flex panels. We have connected a system/wiring diagram of this the things I’m presently setting up and will be powering up within the following day or 2.I would appreciate any feedback from the design to make sure a appropriate and SECURE system before We power up!
The following is a link into the diagram.
Many thanks for reviews.
Correct the 2000W inverter is big and is sized for operating microwave OR expresso device for several minutes each.Yes, how big the inverter may draw a lot of whenever doing sitting idle and it is made to turn on/off effortlessly, Many Many 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 all situations.i.e. all 1/0 cable good lengths add 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 maybe maybe not shown because IвЂ™m nevertheless hoping to get some answers that are definitive just how to hookup battery pack negative (framework connect or otherwise not) and ground (chassis connect or not). The factory setup possessed a battery that is single attached to the frame nothing else. The energy center had all DC negative leads attached to a typical coach club that ended up being attached to the framework along with AC ground. AC basic and ground are not fused (by code bond this is certainly just 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 negative.

Essentially all grounds get to frame. That features AC ground from shore and all sorts of framework grounds of elements. Battery negative is also linked to framework. We included the DC-GPF from Midnite Solar within the last diagram (see express link). We setup tested and every thing worked fine today. Wire length arrived up in several reviews i had off their sources. Keep in mind that the trip that is”round period of the 1/0 cable is lower than 8 foot. from battery pack terminals to inverter and right right back.
One small modification we will make will be your battery pack bank grounding towards the framework ground. I recommend that you move it through the negative battery pack post towards the typical negative bus on the other hand for the shunt.
With car lots, many utilize the framework whilst the return for energy (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 return present through their framework ground connection(s).
The battery pack bank is little for the 2,000 Watt @ 12 VDC inverter. Nominally, I would personally 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 if perhaps you were planning to really run the inverter near 2,000 watts for longer durations of times (lots of moments), I would personally be suggesting a 1.25 Wiring+Breaker derating (224 amps * 1.25 derating=)
280 Amp minimum rated Branch Circuit DC present.
By using the less conservative Marine standards that are wiring 1/0 is perfect for up to 285 Amps
That you do not show breakers/fuses for a few for the wiring making the good coach bar for a few for the other DC loads (hitch plug, cooling fan)–You need to have security for all those connections too (fuses/breakers ranked to measurements of wiring).
