I am not used to this forum and a new comer to travel trailers. We recently bought A camplite that is new 21rbs i am along the way of setting up double 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 day that is next 2.I would appreciate any feedback from the design to make sure an effective and SECURE system before We power up!
Let me reveal a hyperlink towards the diagram.
Many thanks for responses.
Correct the 2000W inverter is big and is sized for operating microwave oven OR expresso device for several minutes each.Yes, how big is the inverter may draw an excessive amount of when performing sitting idle and it is made to turn on/off easily, 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 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 I have perhaps perhaps not shown because IвЂ™m nevertheless hoping to get some answers that are definitive just how to hookup battery pack negative (chassis connect or otherwise not) and ground (framework connect or otherwise not). The factory setup had a battery that is single linked to the framework nothing else. The ability center had all DC negative leads linked to a typical bus club that ended up being attached to the framework in addition to AC ground. AC neutral and ground aren’t fused (by code bond that is just that is done at shore power 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 leaning towards disconnecting trailer framework from battery pack negative.

Essentially all grounds get to frame. Which includes AC ground from shore and all sorts of framework grounds of components. Battery negative is also attached 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 a reviews that are few had from other sources. Remember that the “round journey” period of the 1/0 cable is not as much as 8 foot. from battery pack terminals to inverter and right back.
One small modification we will make will be your battery pack bank grounding towards the chassis 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 lots, many use the framework while the return for energy (DC illumination, automotive radio, and such). Where you have the framework to battery pack ground now will “miss” any loads that occur to get back current through their framework ground connection(s).
Battery pack bank is little for a 2,000 Watt @ 12 VDC inverter. Nominally, i might 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 (many moments), I would personally be suggesting a 1.25 Wiring+Breaker derating (224 amps * 1.25 derating=)
280 Amp minimum rated Branch Circuit DC current.
By using the less conservative Marine standards that are wiring 1/0 is perfect for well over 285 Amps
You don’t show breakers/fuses for many for the wiring leaving the bus that is positive for a few associated with the other DC loads (hitch plug, cooling fan)–You need to have https://find-a-bride.net/ security for many connections too (fuses/breakers ranked to measurements of wiring).
