Thanks for taking time out of your schedule to post this. The easiest way to do this is using Renogy’s inline MC4 fuse/holder, but any type of 40A inline fuse should also work. Thanks for the comment, it shows you understand the Amps x Volts = Watts equation. The refer uses 5 amps, but cycles hourly, so guessing it’s using 2.5 amps an hour, depending on temperature of the van of course. So this is in our solar and electricity guide. We actually wrote a blog post about… Read more ». As far as hookups, we don’t run an AC so we haven’t had the need. So I use about 8 amps to run my laptop, second monitor and play music. So in this case, 100 watt, 12V panels in parallel will give: 12 v (12 to 18v) and 300 watts out total. batts. From your wording and diagram it seems you may have a “positive ground” charge controller, hence the need for all your auxiliary wiring to be a complete loop back to the controller (as opposed to a negative ground which allows you to power accessories from the positive terminal and then ground to the chassis…as is typical in automotive applications). Read our free guide. We didn’t include this on the wiring diagram because the inverter has outlets built into it, so that aspect isn’t really part of the wiring.

And those don’t even need to be charged up all the way at the end of each day. You are welcome to play around with this number, and even combine it with your winter/summer total watts to see what a comfortable system size is for you. We used one of Renogy’s ANL fuse holders and replaced the 30A fuse it came with. This is just a general, you know that the size here is going to work. You’ve wired directly to the controller, your lights, fan and outlets, I assume the lights and fan you purchased run directly on 12V DC current I thought regular lights needs AC, and I assume the outlets are for 12VDC appliances, like a refrigerator or appliances specific to RV’s? John. I’m not sure exactly where in the formula the 1.2 and 1.3 come in the way we set up the calculator (it was awhile ago), but you’ll notice that with an MPPT system, you need less wattage in panels than a PWM one because MPPT controllers are more efficient.

You ran 18awg wire to each light individually and used a wire nut to make your connections to each at the dimmer switch? If you prefer to have hardwired outlets, you can cut off one end of an extension cord and wire it to a standard wall outlet (positive, negative, and ground), which you can then mount in an outlet box and attach anywhere you want. Great site! 1) What’s the wire size you used to connect the inverter to the battery? I detailed the electrical system in Miles Van Camper v3 in this PDF wiring diagram. Thank you so, so much for all the work you both have done on the site and on these resources for our community. We used 4 AWG wiring to connect the switch to the fuse, the fuse to the battery, and to wire the two batteries in parallel. You still need the CC wired to a battery through the battery terminals. Note: In the United States, wire size is measured in American Wire Gauge (or AWG). The best option is a battery to battery charger, many of which double as a solar charge controller. It’s hard on the batteries. What we’re trying to figure out is our daily electrical usage, or our max average. I have a 1975 Ford Econoline 350 with 85k miles and 5 on a rebuild. An example would be phones, fitbit, gopro, kindle, which from what I have seen all require a 5v power supply. It also makes possible voltage differentials between the starter battery circuits and the house battery circuits. Based on my understanding of the equation in Renogy’s documentation, a 40A fuse would be a good choice for four panels. Same amp (your case 155+155). Table of Contents The parts to be installed (on page 1) Figuring out where to put things and mounting the inverter, E-Panel and charge controller (on page 1) Wiring the solar panels and running the cable into the E-Panel (on page 2) The AC wiring and making a 240VAC outlet work with a 120VAC inverter (on page 3) Wiring the Outback turbo fan for sealed inverters (on page 3) Now that you know what size system you need, it’s time to select the actual components. So, if you’re wiring an outlet that will be 5 feet from your fuse box, your wire length is actually 10 feet – 5 for the positive wire, and another 5 for the negative wire to complete the circuit. Thanks again. Renogy 400W Solar Kit (PWM charge controller) We ran 8 AWG wire from the positive load terminal on the charge controller to the positive terminal on our blade fuse block. One other question. I’m resizing now due to an oversight in my original plans. If your budget allows, a system this size should cover most electrical needs (unless you’re trying to run an AC or electric heater).

I am converting a cargo v-nose trailer into a camper and will keep you posted on my progress. Thank you. Since we have sic LED lights wired to one dimmer, we need to multiply the light current by 6 to get our max current: The distance between the dimmer and fuze box is about 4 feet. Let me clear a couple things up: 1) We actually have the 8 AWG wire that came with our Renogy kit plugged directly into the charge controller. 100Ah (x1) Battery (Lithium option), Solar Panel Kits ... 2x 20 amp circuit breakers installed on the positive wire between the solar panels and the solar charge controller and between the solar charge controller and the positive bus bar. We just made sure we twisted all the wires together first, then twisted on the wire nut, then wrapped the wires with electrical tape just below the nut to help take pressure off the connection. See the FAQ for further reading on running a larger inverter. They are both economically-wise and environmentally-friendly, and they quietly generate 12 Volts of DC power that can be fed directly into your RV’s batteries. The lights dimmed on and off, the fan turned on, the outlets charged our phones.

If I remember correctly, the instructions for our inverter recommended using 0 or 00 AWG wire for the battery connection with a 150A fuse. How did you mount the dimmer switch? So your equation should be 3W/12V = 0.25A. Maybe I’ll get one that runs on a 90 watt power brick, and now all of a sudden my lithium battery isn’t quite as taxed by running that laptop. WindyNation 100W Solar Kit (PWM charge controller and battery included), Solar Panels (400W) That’s a pretty intense list. I have read that these lights need to be wired in parallel, I am looking at soldering T splices to make this happen. I’m at the point where I’ve wire all my 110 for regular inlet and a shore power hookup. do you have any information for using three inputs? We don’t save any of your information.
