New Inverter, solar and more

I've wanted to add solar for some time now. After reading a ton of information, I was about to pull the trigger and go for it. Then I ran across a retired electrician that had recently installed about 1200 watts of panels on his roof from Canadian Solar. I was surprised to hear that he bought his lithium batteries directly from the manufacturer in China, at about half the price of anyone in the states. Here's the link if your interested. https://www.rj-lithium.com/ After doing more research, I emailed Mr. Carl at RJ Energy to get more details. I ended up buying 4- 200ah Lithium iron batteries with built in BMS for $3,439.00 delivered to my door. That's a total of 800ah. https://www.rj-lithium.com/sale-1189...-stations.html Mr. Carl was a pleasure to deal with and everything went without a hitch. I highly recommend them. The actual batteries cost 2,380.00, shipping 895.00 and Pay Pal fee charge was 5% (164.00) for overseas transaction. What a deal! It takes about a month to get them. You order them. They set a production date to make them. Then they ship them thru Hong Kong by air.

So I've been busy. First, installing a new Magnum MS2812 inverter w/remote, the BMK and moving my battery location for the larger batteries. Lots of routing 4/0 welding wire and lugs. It works great. Tonight, I just started to look for the run sense wire for the Auto Gen Start. That's going to be a challenge. The wire can be found at the generator switch light. I thought to look at the bedroom switch first, but it looks like I would have to pull the slide cabinet apart to get to it. Running a wire from front to the back is a long wire. I think I go back to that later.

I've mounted 10- 190 watt Rich solar panels to the roof. https://richsolar.com/products/rich-...ne-solar-panel I built all the mounting brackets using 2" angle aluminum in such a way that will allow me to tilt them eventually. I'm sticking them down with 3M, VHB tape. No holes in the roof. I'm wiring two strings of 5ea. in series and will parallel them together for the Magnum PT-100 charge controller. Before ordering panels, I spent some time talking to Magnum support with various panel possibilities to best maximize the PT-100 to it's fullest battery charging ability. (100 amps) That was very important to do. They were very helpful and they also have a panel array calculator on their website help maximize the battery charging amps for the solar controller. In a perfect world, I should have 100amps maximum charging to the batteries. But we all know that solar panel rating v/s actual watts out are two different things. I'm waiting for a few more parts so I can finish the install over the next few days.

I'll posts some pics when done.

Thanks for sharing and I look forward to seeing the pics. You'll be the envy of the park/town/irv2/etc.

I have a fairly simple HandyBob setup on our Class C.

I suspect you'll still need the genset/shore power for running your Air conditioner. Is this correct?
Did you do a usage survey or just opt for going all in?

I'm getting ready to retire and upgrade to a DP and residential fridge so another solar install is likely in my future.

Good luck with the install and remember without pics it didn't happen.....

If the batteries last long term that's a great price for 800ah. Your system build sounds like it's going to be strong for off grid roughing it.

If I'm going to have a neighbor in the vicinity of hearing, a full solar system are the best noisy neighbors.

I'm just sitting here waiting for UPS to deliver a couple fuse blocks and a disconnect for the panels. Yes, I ran the math with air conditioning in mind. I'll be installing a soft start on the air. One air conditioner should be able to run all day and into the evening after installing the soft start. That was my focus on going all out. If you want air conditioning, go big! This is a pic of the batteries installed. The left compartment has holding tanks behind the white board, so their wasn't a ton of storage place for stuff anyway. The right side holds the forth battery, Inverter, transfer switch and soon to be installed PT-100 and fused disconnect. The PT-100 and disconnect will be mounted to the right wall of the right compartment. You can't see it all in this pic, but their is also a neg. bus bar next the inverter and a 400amp fuse on the positive side above the battery disconnect. Because the 4/0 welding wire from battery positive and negative are over 5 feet to the inverter, I had to 2x the 4/0 wire (Per Magnum Support and installation manual). I'll post a pic of the panels after I finish connections and uncover them. Hopefully, I won't be the envy of the park. I'm doing this so I won't need to be in a park.

Very nice install. Looks good. It's not easy to fit extra batteries in these coaches.
I'd like to see a picture of your solar panel install?

Well here's the 10 solar panel array. Rich solar 190 W each. Two strings in series and parallel together. All the roof wiring is finished. Tomorrow I will be mounting in the disconnect switch for the panels and the PT 100. Hasn't been an easy feat for an old man, but I feel it's coming together quite well.Click image for larger version

Here's a few more pictures of the mounts I built out of 2in aluminum angle bought at Home Depot. The rivet nut tool was the ticket. I'm able to screw the knobs into those or remove them for tilting up. I haven't built the tilting arms yet, but thinking of doing a slide track on the edge of the panel. I'll be able to slide them up in the position and tighten down a knob to secure them. That should make it very simple to slip them into place and tighten the knob down. No carrying a bunch of flat metal up the ladder. I'll tackle that later.Click image for larger version

I finished the install today by installing the Magnum pt100, checking all the connections and meter readings. It was late evening by the time I finished up and turn the system on with the sun disappearing behind the trees and the clouds, it still produced 25 amps and topped the batteries off from 91% to a hundred. The mounting brackets I've built we're mainly to give me more surface area for the 3M tape to do its job. I read where the tape is good for 80 pounds per square inch. The 2x4 inch mounts, in theory, should give me 640 lbs of sticking power each.Click image for larger version

I chose the 4950. I applied two strips of tape 1" inch wide, on the 2" L metal. While my brain was on autopilot fastening these to the roof, I accidentally had one turned around. I had to remove it and reposition. The tape is so strong I ended up bending the L metal so bad I had to make another bracket. Up until that point I had some doubts in the back of my head about using tape . Not anymore . The tape is amazingly strong. Keep in mind, the tape must adhere to a smooth, very clean surface. I used alcohol to clean both surfaces.

Dry camping tonight on 4 6 volt golf cart batteries that will cost $400 if they need to be replaced.

Did some quick math here as I feel like you may be shorting yourself a little in the solar controller department.
The quick math says:
10x190w = 1900w total potential
1900w/12v= 158a total potential

On a good solar day, your system will leave up to 58 amps (OR more) on the roof, unused. That's more than 50% more that you won't be able to take advantage of with your sweet lithium batteries.

The reason I ask is that we have 12x180 panels (2160w). They are wired the same as yours, in 2 strings of 6 panels in series. But in my system, each string goes to its own 150v/100a controller.

There have been many times when we've peaked each of the 100a controllers output, gathering well over the nominal rating (180w) of the panels, even as far as up to 25% more shown below where we're gathering almost 500w more.

Here is a graph for the peak of only one of the two controllers at its maximum, 100.6a. This is with only 6x180w panels in series.



Here is peak watts, showing 500w more than nominal (Rated) for the array.
Remember I have 12x180w panels which should only produce 2160w, here because of cloud edge effect and cooler temperatures we're producing much more, almost 25% more.



If your panels can produce 25% more than their nominal of 1900 that'd be 2375w. If we divide that by 12 that's 197amps. (or two 100a controllers.)

I'd suggest that you may want to add another controller in there so as to not have spent all that hard earned $ on panels just to not leverage them to their fullest potential.

Otherwise looking good!

Twenty five percent more than the panel is rated? That's awesome. What brand panels did you use? I've never heard of that before. That's great! I looked at tons of panels, their specs and reviews. All actually produce roughly 15-20 % less than their maximum rating when tested in perfect, direct sunlight.

As most other brands come too, the Rich solar panels come with all important specs. needed in sizing things up. I worked with several techs at Magnum before pulling the trigger. I used their web calculator and input all the panels specs. on many brands and wiring configurations to maximize their 100amp controller. Then called Magnum again to confirm that all my calculation were correct, based on the PT-100 abilities and the solar panels specifications.

I hear what your saying, but I'll have to stick with the guys at Magnum that do this for a living. So far, I don't know what to do with all the power I have anyway! Thanks for the input. I'll try and post a picture of their solar array calculator at Magnum.
