Can you fill a pool with multiple water hoses? Also, please read a few forum post using the SEARCH function as all this is discussed already- before you make a new thread. You can fill a pool with multiple hoses. This answers all of your questions above. Chargers with an equal voltage when...

As said, rare to get 100% of the rated wattage. Need to be aimed directly at sun to get most available light possible. No, they do not last as long, but until they go bad they are the same as any other 100 watt panel. How are they attached? Danger is they lay on the van roof and trap water...

Are there no upright 12v DC fridges that will be similar price? The upright do take up less room than the chest sty bc the door opens into the walking space, not into the cabinet space. I have a DC chest fridge and will never go back to propane. I put 1.75 inch thick styrofoam insulation...

So, the power is going to be used in the camper but the batteries and everything will be in the van, and the solar panels on the ground? You don't go through the body, you go through the floor, between the fender and the inside wall perhaps. Use an Anderson plug that hangs out at the bumper...

Yep, exactly. Most use a switch like this: With this one you can charge either or both or neither. The solenoid or relay option with toggle above will do the same thing too, but just more complicated, and only if you must have a remote toggle switch. They key is that both batts should have the...

Consider adding another charge controller and just having your odd panel be a separate charging system to the same battery. You can have multiple solar panel/charge controllers feed into the same battery(s) and still be fine. volts plus volts plus volts of the 3 panels feed the battery, then...

Sounds like you most likely got it figured out with firmware.... My only suggestion, and might help a lurker who has shocking issues different to yours is to: Make sure all of your wires on AC side are wired correctly, do NOT reverse Hot and Neutral. Reversing them on anything plugged into AC...

maybe don't get the flexible ones this time. You already know why....

lol. yea, he gave up pretty quick, or wether got cooler. Is not necessarily bad to continue a topic as you can see the post to reader ratio means there are a lot of people reading the topic for some reason, maybe to find their own answers to the same question.

what is the question? Are you asking about vehicle aerodynamics or the forces on the panel? Roof wind turbulence is so messy, there are no direct from-the-front wind forces, it all swirls around unless you drive a soap bubble.

Depends on the crossbar. You talking the stock luggage racks on a mini van or after market roof racks for toys? Round, flat, oval? Aluminum, steel? Does the rack come off? How many panels, will there be panels side by side touching?

correct. the heated air is the air you heated in the cabin, not cold outside air, I should have been more specific about blowing fan air on it. *** edit, Just an update to confirm... 14 degrees the other night in the camper and I still had to leave a window and a roof vent cracked to keep...

There is the diode in that little box too, or something. You will have to buy one and make modifications yourself if you want it. Others are right, this is dumb. Im not trying be mean, this is dumb and your reasoning is invalid. Use glass panels!!! Flex panels are for dire situations, not...

So, I went back to post #1. Yea, you didnt start out with all the info, only dripped it out, and after 4 pages now Im not going to sift through to find it all.... What I gather is you are living in a van that is not built out. You stuck up some cork and called it insulated? You have bare...

I had a class C with the front half of box, about 7x7 foot area with bed over cab, and the 13.5 AC unit was still over-kill in a 120 degree desert. A 9k would have been plenty for that. When I opened the door and cooled the entire 15 foot box then the 13.5 was still fine. I would put in the...

None of your loads DC are worth a worry. The diesel heater will use amps when heating up the glow plug, mine is less than 8 amps, but after that it is only the fan that pulls power at about 3 amps max. I cannot argue with Will, but I think for your needs today that aluminum wire is more than...

One option is to take the existing battery to a Battery Store/ repair shop and have them put in all new 18650 batteries. This is a simple task for a battery enthusiast. 18650 batteries are in everything including the tool 12v battery you mentioned. They are the favorite for Tour de France...

I think part of the answer is to swap out the alternating current compressor for a DC compressor so you can run the compressor straight off the battery. This have to be 12v compressor. Then you have a fan that is still alt current, so you still would need , though be it a smaller inverter, or...

I think 9k is plenty enough as long as you are insulated, the glass being the biggest heat loss. I have a 9.2k Coleman Mach roof unit, not mili-split, but is 9k range. It is in a cargo trailer and is way way more than needed. If they had a 4K I would use it. As is the compressor runs just...

Actually, the electric company WANTS you to do solar and sell it to them. Their other option is to build a new power plant. That is not an option they want. It is much cheaper for you to build the power plant and sell them electricity. Yet, IDK why they make selling solar power so difficult...

I would not. Get another MPPT controller and run that into your one battery at the same time as the other one charges it. Things break, and this way you have two complete solar working set-ups. The charger/controller is not the expensive part, $50 or less on ebay for you small wattage. I...

thanks, yes I do have great insulation as I built it out myself and paid attention to things that matter. I dont ever use a fan to move air in or out when heating, just crack a window or top vent is enough. Yes, cold air comes in, but is needed to even out the temps as the heat is just too much...

hiding the systems in a box is still kinda useless unless you plan to hide it until post-emp. How to protect a working system is the question, not how to hide it in a box. IDT anyone has missed the faraday box option, nobody is asking how to put anything in a faraday box, this is simple, they...

I have not checked to see what each pin on the rs485 does, but that is a generic computer industry connector, not just for solar stuff, so good chance they use the pins as designed to be used. For example, all RJ45 pins would either be A or B style. In computer world people do not change up...

sure, that is how it works. That is why people DO use it, but is not the topic of why people do NOT use it. If you buy a store bought rv with this stuff in it already then you do use it one would assume. Why do people who do not have it not go to the trouble of installing one? or is this all...

I think the reason is that for houses, when power goes out you want it to switch by itself, power does go out at times. In an RV, this is not really a concern. If you have shore power then that is more rare for people with full capacity solar/battery, bc those ppl are set up for boondocking or...

1 yep. you really should just get the proper lithium charger to begin with, you will end up getting one anyway, just get it now. 2 just run it, you will never get to 100% charge, but you will not get to zero either... You are basicalyl giving it a float charge at higher amps/ lower volts than...

remove one axle? or are they all attached together? Yes, mis-matched axles and cargo weight can cause harsh ride. By axles I mean leaf springs. The only time I have heard of solar panels being damaged by harsh trailer rides is from newbies imagining it happening, but not in reality. A big...

What fridge? DC compressor fridge or gas? If DC comp fridge then that likely one of your biggest needs unless you play vid games all day. OR everything else might add up to more, fans running can be 1-3 amps alone. So, a power audit is needed. 800 watts sounds like plenty for what you...

It might do it, but some say it can damage the battery over time. 450 cranking amps might be what your 5500 ask for. A lot for the typical lithium to put out at once. For a motorhome you could connect it to the vehicle starting battery, should be no danger of depleting the vehicle starting...
