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 in the act of setting up double batteries, Inverter and Midnite KID solar with 4x100W flex panels. We have connected a system/wiring diagram associated with the 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 from the design to make sure a suitable and SECURE system before We switch on!
Let me reveal a web link into the diagram.
Many thanks for remarks.
Correct the 2000W inverter is big and is sized for operating microwave oven OR expresso device for several minutes each.Yes, how big the inverter may draw an excessive amount of whenever doing sitting idle and it is made to turn on/off effortlessly, 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 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 includes a DC GFP that We have perhaps perhaps not shown because IвЂ™m nevertheless looking to get some answers that are definitive simple tips to hookup battery pack negative (framework connect or otherwise not) and ground (framework connect or otherwise not). The factory setup had 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 ended up being attached 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). So my question is do I disconnect the battery pack negative from frame and then leave grounds to framework? Or float ground or something different? 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 pack negative.
1.2KW down grid system; 2 strings of 2ea 305W 60 mobile panels on a redneck ground mount; MNPV3 combiner feeds a MN Classic 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 quick extent, energy hungry devices.
Essentially all grounds get to frame. Which includes AC ground from coast and all sorts of framework grounds of components. Battery negative normally attached to framework. We included the DC-GPF from Midnite Solar when you look at the last diagram (see express link). I setup tested today and each thing worked fine. Wire length arrived up in a reviews that are few had off their sources. Observe that the „round journey“ amount of the 1/0 cable is not as much as 8 foot. from battery pack terminals to inverter and straight back.
One correction that is minor will make is always to your battery pack bank grounding towards the framework ground. I will suggest that you move it through the negative battery pack post towards the typical negative coach on the reverse side of this shunt.
With car lots, many make use of the framework given that 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 return current through their framework ground connection(s).
Battery pack bank is tiny 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 flow at maximum AC inverter score.
1/0 cable is NEC rated 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 minimum mail order wives that is amp Branch Circuit DC present.
If you are 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 of this wiring making the bus that is positive for a few of this other DC loads (hitch plug, cooling fan)–You must have security for people connections too (fuses/breakers ranked to measurements of wiring).
