I am not used 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 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 you will be powering up within the day that is next 2.I would appreciate any feedback regarding the design to make sure a suitable and SAFE system before We switch on!
Let me reveal a web link towards the diagram.

Thank you for feedback.
Correct the 2000W inverter is large and is sized for operating microwave oven OR expresso device for some mins each.
Yes, how big is the inverter may draw a lot of when performing sitting idle and it is built 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 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 includes a DC GFP that i’ve maybe perhaps perhaps not shown because I’m nevertheless hoping to get some definitive responses about 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 attached to a typical coach club that had been linked 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 battery pack negative from framework and then leave grounds to framework? Or float ground or something different? I’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 I’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 elements. Battery negative normally linked to framework. We included the DC-GPF from Midnite Solar into the last 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. Remember that the “round journey” duration of the 1/0 cable is significantly less than 8 foot. from battery pack terminals to inverter and straight right straight back.
One correction that is minor will make is always to your battery pack bank https://hookupwebsites.org/chatzozo-review/ 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 the shunt.
With automobile lots, many make use of the framework once 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 tiny for a 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 ranked for
125 to 170 amps (in conduit)—And if perhaps you were likely to actually run the inverter near 2,000 watts for extended durations of that time period (lots of mins), I would personally be suggesting a 1.25 Wiring+Breaker derating (224 amps * 1.25 derating=)
280 Amp minimum rated Branch Circuit DC present.
If you are using the less conservative Marine Wiring standards, 1/0 is perfect for well over 285 Amps
You may not show breakers/fuses for many for the wiring making the bus that is positive for a few associated with other DC loads (hitch plug, cooling fan)–You needs to have security for everyone connections too (fuses/breakers ranked to size of wiring).
