This is my Solar / Wind Power setup. The vid is a little long, but I had to cover a lot of important information.Video Rating: 4 / 5

8:44? kee clicking it lol
We had a BAD hailstorm? several years ago. It tore up everybody’s roofs and cars. Windshields busted, etc… the panels just laughed at it… no damage AT ALL…
how? do your panels hold up under hail storms…..
@mijemu Yes you can. You’ll just need? to use either a combiner box to combine the outputs. Using 2 inerters that are 120v only to provide 240v support is trickier though but it can be done.
Can? you hook up more than one inverter to the batteries? is there any problem with that?, i am speaking in off grid terms.
The main issue is that the phases wouldn’t be in sync. The amount he would be putting out onto the grid system would be so small that they probably wouldn’t even notice. Being out? of phase, they may notice.
But as he pulls the electric meter, he has no issues with this anyway.
I am not an expert, that inverter into your electrical system and will? run your house , my concern would be there must be a way to cut off power going to the electrical wires leading to your house, it is just a theory you very well may light up a repairman, or rattle his teeth depending on the size of your inverter, excellent video thank you for sharing Mike
MPPT charge controllers will also let you? use the cost efficient big boy 235, 245, 315 watt panels.
Batteries, yes. If you are wiling to go to 24v, you might as well go 48v if you can find an inverter for it (or willing to pay for a 2KW+ inverter)
If you get a MPPT charge controller, which is much more efficent, you can run higher voltage between the panels and the charge controller and even staying at 12V the #8 will be even less of an issue.? Each group of panels will have to be on their own controller unless you can get the string voltages mostly synched up. Morningstar is a very good brand
Bad weather could kick your ass over time xD
Here in Germany we? had very much cloudy days and even thunder and all this over the months, still now in summer… Very little sun at all <.<
You can’t count on weather and mono/poly is like gambling with luck. Only sunny days give you any power. But most days aren’t sunny or it’s risky to count on good weather at all, just logical thought. Better go for amorph and have a truly secured gain every day :-)
That’s true, but efficiency is above space me? thinks. Still with little space you can get some watts too. But they are “everyday weather” prooved. You have better everyday gains total with amorph than mono or poly silicium ever can do. Because they have double gain, but “only” at good sunny days. While cloudy days, you get like no power. So you have a bigger risk to stay without power too. Amorph serves with using all daylight and is more secure for farming calculations :-)
I have less than 15′ from panels to controller now, but when I add the other panels i’m not sure.
Question: These 12V can be tied together to make 24v correct?
I may just do that and go? 24v altogether… or… use a couple of the batts to run a small 12v system and 8 of the batts to run a 24v… whaddya think?… and thanks for your comments.
If you? got the space for them, amorph is great. Need double the space than monocrystaline.

Be sure to use to voltage drop calculator.
#8 is bare minimum to be code compliant with 25 amps (estimated) over 40 feet (estimated). But you wlil have a 13.4% voltage drop with a meager 12v.? Expect a lot of charge controller low voltage faults when you get those kyoceras hooked up. Get a fatter wire. #2 AWG will get you a 3.4% voltage drop. 4/0 for those battery connector wires.
amorph solar panels are the best. They produce power even with cloudy weather and no directly sunlight. So you? have more security than going with silicium ones which only work with more directly sun and clear weather. You could forget about a wind generator too. Amorph is the future and works every day, after the sun goes up and it’s bright outside, doesn’t matter the weather :-)
You know what would be cool if Business like say BestBuy started using solar for their lighting and maybe a few other little thing like powering up the game? consoles. I mean it would cost them what $7000 and save them that in two years maybe if they didn’t give their CEO a $40 Million dollar bonus for doing a crappy job. they could afford to do this for all their U.S. stores but maybe in 20 years when i’m almost 50 I’ll see this happen if i’m alive…?
Nice set up, my hints on using it for max. efficiency with solar panels. Split out your feed system to the house, run small usage (lights, ceiling fans, TVs, electronic stuff) during the day when you have surplus solar power. This will cut down on your power bill and still let you keep the bats charged. I know it’s a pain but the main thing? is to save money, right? It’s worth the cost of extra wiring. Most folks just want to “plug” their house in and run everything. Think outside the box.
You would good if you ran everything? on DC like in a RV.
Starting out with that batteries was a smart move at that price. Don’t let an under performer battery with a dead or close to dead cell pull the other batteries down in voltage. Watch your battery voltage always, get an ac charger for the winter time so you can keep the batteries on float 13.2V? – 13.5V for as long as possible.
Nice batteries!…good? score!
Cellphone towers operators are now ditching battery’s banks for
Hydrogen PEMFC – Proton Exchange Membrane (PEM) Fuel Cells
Why you can store a Over a Months worth of backup power in a LPG Bulk 500G Tank (GAS Hydrogen or Liquid Hydrogen) and keep it stored well over 10+ years and still use the gas 40 years later and it will still give a months worth of power
PEMS have lower maintenance? due theirs No Electrolyte to Balance monthly and No yearly Sulfation and desulfation
#8 wire from panels to controller. #2 cables at? batteries
The batteries are overkill for that productivity amount, especially with AGM (expensive).? You need to upgrade to 48 volts. Large 12 volt inverters are hard to find. 24 volts can be found any size. 48 volt is hard to find small inverters for. For safety you could use more grounding. Your panel/combiner box to charge controller wiring is probably very undersized also given you are using 12 volt probably on the default 10 AWG MC-4s. Get a MPPT charge controller and you won’t need fatter wires.
200 watts is? wimpy. The batteries are overkill for that productivity amount, especially with AGM (expensive).
so bigger the battery bank is and so less the power you? are obtaining from small solar panels . you need to install more panels .
