I am not used to this forum and not used to travel trailers. We recently bought a brand new camplite 21rbs where i am in the act of setting up twin batteries, Inverter and Midnite KID solar with 4x100W flex panels. I’ve connected a system/wiring diagram regarding the the thing I’m presently setting up and will also be powering up within the day that is next 2.I would appreciate any feedback in the design to make sure an effective and SECURE system before We switch on!
The following is a web link to your 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 commentary.
Correct the inverter that is 2000W big and is sized for operating microwave oven OR expresso device for a few mins each.
Yes, how big the inverter might draw a lot of whenever doing sitting idle and it is made to turn on/off effortlessly, Many Many Thanks!
All breakers and cables sizes are to spec. This is true of power center, solar and inverter. Wire lengths are quick runs in every full instances.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’ve not shown because IвЂ™m nevertheless looking to get some answers that are definitive just how to hookup battery pack negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup had a battery that is single attached to the framework nothing else. The energy center had all DC negative leads linked to a typical coach club that ended up being linked to the framework along with 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 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 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 IвЂ™m tilting towards disconnecting trailer framework from battery pack negative.
1.2KW down grid system; 2 strings of 2ea 305W 60 mobile panels for a redneck ground mount; MNPV3 combiner feeds a MN Vintage 150 located 100′ away; 12V 460AH FLA battery pack bank abilities a cabin-wide 12V DC system along with a Cotek 700W PSW inverter; Honda EU2000i and IOTA 55A charger bridge cloudy times and a Champion 3800W generator for brief timeframe, energy appliances that are hungry.
Fundamentally all grounds get to frame. Which includes 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 today and each thing https://hookupwebsites.org/dominican-cupid-review/ worked fine. Wire length arrived up in a reviews that are few had off their sources. Keep in mind that the trip that is”round duration of the 1/0 cable is not as much as 8 legs. from battery pack terminals to inverter and right straight back.
One correction that is minor would make would be to your battery pack bank grounding into the framework ground. it is suggested that you move it through the negative battery pack post towards the typical negative coach on the reverse side associated with shunt.
With car lots, many utilize the framework whilst the return for energy (DC illumination, automotive radio, and such). In 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).
The 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 rating.
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.
By using the less conservative Marine standards that are wiring 1/0 is perfect for up to 285 Amps
You don’t show breakers/fuses for many regarding the wiring making the bus that is positive for a few for the other DC loads (hitch plug, cooling fan)–You must have security for the people connections too (fuses/breakers ranked to size of wiring).
