Hey we’ve all seen these guys with one million watts of photo voltaic panels on their roof, and 30 batteries within the stomach of their camper boasting how they will run each of their AC models and an air fryer whereas they watch TV of their rig. This text isn’t about a kind of programs, I’m not that man.
My Spouse and I’ve been residing on the street full time in our RV for a few yr now. Once we first acquired began we had extra kinks to work out of our system than we thought we did, and spent most of our time bleeding cash in gas and campground prices. We tried our hand at Boondocking at a Harvest Hosts one night time, and at 2 a.m. the low battery alarm began going off. Hell we didn’t even make it sooner or later, we left our campground with full hookups at 9 a.m., acquired there at midday, and 14 hours had no juice left.
Properly now we have to work out a solution to hold sufficient cost within the batteries in order that I would be capable of sleep till dawn. We hadn’t achieved ANY analysis in any respect on RV Photo voltaic, however then I got here throughout the 400 Watt RV Photo voltaic Package from Renogy. It appeared to have the whole lot we wanted to throw some panels on the roof, and hold our batteries charged sufficient to have the ability to use the lights within the kitchen and hold our low battery alarm from going off, so we ordered it.
We ordered it from Amazon, and it confirmed up at my buddies home in 3 days, and it did include ALMOST the whole lot we wanted to finish the set up. The one issues it didn’t include was the roof sealant, and a go by way of for the wires to go from the roof down and into the RV, however we ordered these as effectively, so now we had been able to go.
You’ll be able to watch my quick Set up video right here:
The RV Photo voltaic equipment from Renogy comes with 4 100 Watt Photo voltaic Panels, a 10 amp inline fuse, panel combiner plugs, cables to go from the roof to the cost controller, a 40 amp MPPT Cost Controller, a Battery fuse, a Bluetooth antennae so you may monitor your energy manufacturing with an App in your cellphone, and cables to go from the controller to your batteries.
The instructions for set up had been fairly straight ahead, besides how the panels themselves needs to be wired collectively on the roof. There are a couple of choices for placing them collectively, and I’ll admit I did it ‘Fallacious’ the primary time. With photo voltaic panels you might have the choice of wiring them in Collection, Parallel, and Collection-Parallel.
Trying on the components available, and the included combiner plugs, I assumed they wanted to be wired in Parallel. Which is when all of the Optimistic cables tie collectively, and all of the Adverse cables tie collectively, then go all the way down to the Cost Controller. Whenever you wire them this manner, all the Amperage from every Panel is added collectively, and on a full Solar day, will pop the ten amp fuse.
I replaced the fuse, and rewired them in Collection, Optimistic to Adverse, Optimistic to Adverse, Optimistic to Adverse, Optimistic to Adverse, then all the way down to the Cost Controller and the whole lot began working completely.
We had 200 amp hours of normal outdated Deep Cycle Lead Acid batteries from the manufacturing unit, so we figured that needs to be sufficient storage to maintain us going. We’ve got a residential fridge in our RV that runs off a 1,500 Watt Energy inverter that auto switches ON once we unplug the RV at a campground.
IF we ONLY use the 12 volt lighting, and depart the fridge working like regular, the photo voltaic will cost our batteries throughout the day on a decently Sunny web site, and get us by way of the night time with no battery alarms. Realistically that’s all I used to be searching for, so it was doing what it wanted to do, and will get us off grid ceaselessly sufficient that I WOULD spend the cash on it once more if we had been to do it over again.
Relating that topic, of If we had it to do over once more, There are issues I’d do in a different way, like altering out the batteries, and searching into the right way to dimension the system to get a sure variety of hours out of it. BUT…
Based mostly solely on, whether or not or not this technique carried out as I imagined it will, Sure, it did.
The equipment got here with most the whole lot wanted for the set up, It does cost the batteries throughout the day, and the set up was straight ahead. If you’re searching for a simple RV Photo voltaic choice, that may get you off grid for the weekend with out plenty of difficult math, that is it. Simply ensure you get the roof sealant, and a go by way of, and it couldn’t damage to seize a spare fuse to throw in a junk drawer simply in case.
Full disclosure, in case you click on on considered one of our Amazon hyperlinks, and buy this stuff by way of them, we do get a referral fee. It doesn’t price you something further, however it does assist us throw some gas within the tank so we are able to carry on trucking.
Keep tuned for my observe up article on the issues I’d do in a different way, and the right way to dimension a system to get you thru a complete day of clouds and rain.
