Greetings: Wow Wally World batteries. Battery connection +. to + , - to - to - is parallel not series. Parallel will not make it 24V.

Got a template for wire setup? I want this on my cargo trailer

If you added one more battery, you could probably run a small 5000 btu A/C unit on DC power over night without even running a generator. Then start the generator in the morning to charge the batteries and power the A/C during the day. Great setup you have.

Mini Solar Winter Tipp: You can steplessly dim down a Beuler and all other hungry electricity consumers with a 5000W dimmer (EUR 7). I run 5 dimmers in parallel on an 850W inverter. Kettle 2.2KW at 150W runs 12 hours a day, so the water is always hot. The room is also nicely heated. 2.5KW washing machine runs in parallel with dimmed to 200...400W. Iron, dishwasher, oven, electric heater, coffee machine, all internal heating are throttled with me. Videos about it on my channel kzbin.info/www/bejne/m3SVoJ-YeKebnpI The inverter stays cool, quiet and the MOSFETs remain intact because extreme current peaks no longer arrive at the inverter. Now every Mini PV Inverter is enough to sell large devices. So with the dimmer all internal heaters/devices can be turned into base load devices that stay almost permanently ON while drawing very little current.

Your shunt will only measure the power to the DC loads and not the inverter/charger , so you won't get an accurate read on your batteries' level of charge. It should be the only thing connected to your battery ground, with every other ground connected to the other side of the shunt.

27th! Suck it everyone else

Decent video. I guess you already read the other comments: You put two 12 volt batteries in parallel to keep them 12’volt, with twice the amperage or ah. Series would make them 24 volts together. I would suggest electrical connectors on your outlet and disconnect box, so the box’s will not cut into the Romex wire sheath. Also stranded wire is better for rv’s. Solid wire is more likely to break with movement. It is easy to find it, already in greenfield (flex) conduit. I’ll look forward to seeing the rest of the build. The cabinets look great so far.

How long can you run an air conditioning unit with this setup? I thought you would need a generator but, I'm intrigued with using batteries and an inverter.

Thanks for your video! I'm setting up the electrical in my cargo trailer based on your video! I have just about everything u do but that Converter/Charger with Charge Wizard component and some kind of fuse circuit breaker. Although, I have a Renogy DC-DC dual charger w/MPPT to charge my batteries (fr both my solar panels and tow vehicle's battery). QUESTION(S): Do I need that charge wizard or will my Renogy charger suffice? Also, do I need the 30amp 2 space 2 circuit lug center? Or can i use a Blue Sea Systems ST Blade ATO/ATC Fuse Block (either/or)? I'd REALLY APPRECIATE ANY RESONDENTS since I am quite the novice and cannot seem to find anyone for hire to help me! Thank you, ! Art-n-Kiko, Seattle, WA.

Fyi series is 24v and parallel is 12v

You did very good. Remember, don't spend too much money on what others glamorize. A simple system does the job. 200 amps is more than enough and have some portable power in case of emergency. Some youtubers enjoy inflating the system to very expensive and unnecessary components to favor their sponsors. Many are not into that, and just want honest information to setup a simple system that fits their budgets. You will learn in time. But you seem honest and have learned on your own.

One question. Where's the fire extinguisher? Because you're going to need to use it.

Hey Chris, I would change the AC power wire coming in to a 10 gauge wire due to its ampacity.

I hope your family isn't staying in that trailer with you if those are lead acid batteries, I mean there are thousands of videos showing how dangerous they are in a enclosed situations unless stored on the outside, you can't go wrong with lithium batteries stored inside🤔

You need strain relief everywhere ac wires go through boxes.

What kind of wire / cable for your outlets?

Series will double your voltage, parallel wiring keeps volts the same but increases amp hours. Some use two 6 volt batteries and connect in series to give 12 volts. Connecting two 12 volt batteries in series will give you 24 volts..

Jumper cables 4 gauge red and black ,,

Hi there I really liked your videos, very well explained. I have a couple of questions, I am really new at this so please bare with me. I purchased a 7x14 cargo trailer and it currently has solar, however, the previous owner only put 1 outlet inside. It has 1 12v battery, and 1500W Cen-Tech power inverter with a 3,000-watt surge. I would like to add 4 more outlets in the trailer and a couple of more LED lights. I am going to install an AC unit but that's it. No fridge, no TV, just 4 more outlets for Charging laptops, or cell phone, shaver, and possible shower. I do want to get another battery so i will have Parallel connections. The solar panel is so small its like a size of a picture frame mounted on top of the box in front of the trailer. Now I can plug the trailer to the RV outlet since it has a plugin from the outside. My question is do I need a bigger solar panel? Is my inverter big enough? I am only using the trailer 2 times per month. Thank you for your advice.
