Here is the much requested overview of my solar electrical power system... Here is where I purchased my solar panel and charge controller from : http://sunelec.com/ And here is the jump off page for my solar setup with the plan and links : http://www.bethnchris.com/category/construction/sps/ and you can join me on facebook here http://facebook.com/buffcleb If you have any questions just let me know and I will do my best to answer them...

Is your system still working well

Now update on my Solar Power... I now have 31 panels on my roof. I have twelve 6 volt golf cart batteries to make a 12 volt, 1,290 Ah Battery Bank. I have been running my whole house now for just over 10 months straight off my solar power. I no longer have the power company or a power bill. With this weather from Hurricane Mathew, Yesturday was a cloudy gray dark clouds and rainy, My solar panels produced NOT as much power, But produced enouff to run everything in my house and fully charge my batteries. I have came a long way since the past 11 months. I have learned a lot. I learned that ANY THING with CCA on it will NOT WORK.. .

if you have a good quality MPPT charge controller it doesn't always matter what the solar panel voltage is compared to the battery bank.. my system is a 12 volt battery bank with four 250 watt - 30 volt panels wired in series.. that makes the panel input 120 volt to the Midnite Solar charge controller..
btw, this is a CSA approved system designed by a reputable solar power company.. is NOT my design..
I gave them the room available on my RV to mount panels and the fact I wanted a 12 volt battery bank because most of my power use is 12 DC directly from the batteries not 120 volt AC from the inverter..
the system was designed by them to give me the best design for a 1000 watt set of panels ( biggest set that would fit on my RV) and a 12 volt battery bank.. there are several ways to wire the batteries (12, 24v, 48v etc) and several ways to wire panels (series, parallel, and series/parallel) that would give different voltage input so if you wanted, you could have say a 24 volt battery and a 30 volt solar input... what was explained to me is the solar input voltage must be higher than battery voltage, you could not charge a 48 volt battery with a 30 volt panel BUT you can charge a 12 volt battery with a 120 volt panel -
cool system, and great video. I like that you get to the point and give detailed info. Many people talk and talk about what they are going to talk about, and end up with a 5 min intro for a 10 min video :). Thanks for the video.

You can make it yourself, just loook and learn from INPLIX .

Great job mate 🇬🇧

As for your outback Charger you did right. . it will do all you ever need and more then some others will. Neil

Great job putting your system together. Looks good to me. How about an update?

You're answering all my questions about the build of my cabin and the solar system. If I have a similar set up to you...I've seen one I believe the two panels combined give 400w and it has the controller and inverter and wiring included (on EBAY there's a couple like this for around £300-400 GB Pounds I'm not sure of the exchange rate? ) and I am going to get 2 x 12v deep cycle batteries (they're expensive but I am no electrician and I would rather have two new ones than second hand which may have problems I can't fix). I am getting a small woodburning stove (I've forgotten what the unit of heat is called "therms? Lol!) But the output is 5 (I'm sure it says kw but may be wrong I plead being female for this heh heh!) With back boiler fed from rainwater harvesting (solar should run pump) the question is, with all this up and running (it won't be until autumn) will I need a generator too? I'm going to see if the gas company will swap my empty butane cylinder for a propane one just in case (it's the same company and they used to only do the blue butane cylinders but now do red propane ones - I still believe most people use butane and the propane seems to be more for RV"s and canal boats etc)
Sorry to give you such a complicated question but to recap so you don't have to read all that is, on top of the solar and woodburning stove/water heater do you think I will need a generator and the propane (the stove has hotplates)? -
Sir, how many amps is your solar controller?
-
I was wondering how the transfer of power works, and by that I mean when the inverter goes to the fuse box does it work the same way as your power company's ? The main that supplies the bus?

Nice video.
First class tutorial of your off grid solar power energy.
I just Subbed you in my channel. -
What kind of batteries do you have ?? Are they 12 volt batteries?? I have 12 solar panels, 5 on my roof now hooked up to two group 8-d batteries. the rest are in a closet for now until i better batteries. i burned up my first set in two months running what little i ran. they were marine batteries,, so from the dealer i got the two group 8-d batteries, and now they are almost fried / bad too.... one thing i learned is to go total off grid, the batteries must be golf cart, or forklift batteries, and if they have anywhere cca on them, they are starting batteries and wont last for solar... so i am deciding to go 6 volt batteries and pair them up to make 12 volts, and have 4 pairs which will be like having 4 twelve volt batteries.. i live in a mobile home, and plan to get total off grid, and do away with my power company.. by the time its over with, i will have 18 - 25 panels... i want more panels for rainy days so this way they still fully charge my battery bank on cloudy rainy days..

Great video.
-
but I would be living only on solar
-
it would only be for a house hold frigde a few lights computer and a Lil music equipment
-
so how many battery's and panels would I need to live with only solar power
-
Hi, great video and channel! I was curious as to how you have the batteries wired, positive to positive neg to neg?
-
You really cut the connectors off the end of the panels? You know....they make connectors that allow you to connect panels together. And they are only $5 or $8 bucks...

ts not clear lts clear to u your way draw a diagram then make us make understand according to diagram and practically too.
