I am a new comer to this forum and a new comer to travel trailers. We recently bought a brand new camplite 21rbs where i am along the way of setting up double batteries, Inverter and Midnite KID meetme solar with 4x100W flex panels. I’ve connected a system/wiring diagram associated with the the things I’m presently setting up and will also be powering up within the day that is next 2.I would appreciate any feedback from the design to make sure a appropriate and SECURE system before We switch on!
Listed here is a website link towards the diagram.

1kw panels into 1xMNClassic150 700ah 12v bank morningstar inverter that is 300w
Thank you for responses.
Yes, how big is the inverter might draw an excessive amount of when performing sitting idle and it is made to turn on/off easily, 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 full 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 primary problem.
The Midnite Solar KID includes a DC GFP that i’ve perhaps perhaps not shown because I’m nevertheless looking to get some answers that are definitive how exactly to hookup battery pack negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup possessed a solitary battery pack negative 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 this is certainly just that is done at coast energy panel). Therefore my question is do I disconnect battery pack negative from framework and then leave grounds to framework? Or float ground or another thing? I’ll be setting up the GFP today that connects between battery negative and ground and basically disconnects the PV+ during fault. As shown now it will trip while you state.

Fundamentally 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 when you look at the last diagram (see express link). We setup tested today and each thing worked fine. Wire length arrived up in several reviews we had off their sources. Keep in mind that the “round journey” period of the 1/0 cable is significantly less than 8 legs. from battery pack terminals to inverter and right right straight back.
One small modification we will make would be to your battery pack bank grounding to your framework ground. I would suggest that you move it through the negative battery pack post to your typical negative bus on the other hand associated with shunt.
With automobile lots, many utilize the chassis since 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 get back present through their framework ground connection(s).
Battery pack bank is little for a 2,000 Watt @ 12 VDC inverter. Nominally, I would personally 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 Amp minimum rated Branch Circuit DC present.
You don’t show breakers/fuses for a few associated with 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 measurements of wiring).
