36V 315W 9A solar panel system setup

[only1originalme]

I have 8 315w 9A 36V solar panels. My boss wants me to put these into an array of 4 panels each. and then run them together. what all do I need in terms of charg controller,inverter,ect...?Any help would be greatly appreciated.Thank you in advance.

Before you decide how to string them you need to know the charge controller or inverter. Are you trying to connect to a grid tie inverter or to charge batteries?

its going to charge 12 6 volt batteries @220 amp hours each ran in series and then parallel.

Why not just purchase the proper size cells and eliminate any parallel wiring of batteries? If you purchase 2v L-16 style cells, you would only have one string of batteries and less cells to inspect and fill with water.

2v L-16 cells?what are those? wouldn't I need around 18 of those because they are only 2 volt just to eaqual one 36 volt battery? I'm confused. HELP!!!

Your batteries are wired for 36 volts? 36 volts is a non standard voltage for solar battery banks. 36 volts is more for golf carts, floor polishers and warehouse lifts. I thought you were running a 24v system and that would require 12 X 2v cells. If your system is truly 36v then yes you would need 18 of them. Either way, these batteries would be all in one string, allowing you to obtain Amp Hours needed w/o paralleling any of your batteries.

Never ever use parallel batteries unless it is necessary to meet a specific AH capacity. For 99.9999999% of all solar users, there is never a reason to parallel batteries because cells capacity goes as high as 25,000 AH. You are no where close to 25,000 AH batteries.

So if you need 440 AH which is what you said, then use 440 AH batteries. Something like 6 Trojan L16H batteries a 6-volt 435 AH battery. T-105's are not the right battery for you.

Once you get to 400 AH batteries, the voltage has to be lower or else you could not lift or handle the weight. A 2-volt 4000 AH battery weighs 500 - 600 pounds each. A 6 volt 4000 AH battery if it were made would weigh 1500 to 1800 pounds.

Here is a cool video using a single 2-volt 25,000 AH submarine battery making Ball Lightning. Note the size of the battery at 5:20 mark. In a submarine there is 300 of them in series.
