Question 1

Is possible to safely series connect 2x200w=400w (@90voc) into a 150v 40a scc to 2 parallel connected 12v 170a batteries and 2200w 12v inverter?

Accepted Answer

Yes, of course. When you hook up 2 panels in series, the VOC is about 90V, your controller is 150v 40a, that is no problem. It will be a perfect solar system.

Question 2

Is it better to have 1 200 w or 2 100w panels?

Accepted Answer

It depends on a few factors.   Is your charge controller an mppt  type  .  Mppt loves extra voltage.  As long as it can handle it. .  Will your panels be behind a  window or shaded or will they have full sun all day.       If I have a 24v panel that outputs 5 amps and a 12v battery my mppt gives my battery  12amps. If I use instead a panel  that uses 24v and 10a the amperage to the battery is 20a which is my  charge controllers  limit.  I can do tests before I buy because I have a lab bench power supply  btw.   If  say you have two 100w panels  hooked up in  parallel each putting  out 5a  it would be 10 amps total  coming from the panel portion and you'll get  
a little over 10 amps going to the battery.  And if you do  the two 100 watt panels  in series  you'll  get 
Bout 34v total  going to the charge controller  and 5a .  But  because it's a high voltage you'll be getting more amps  going to the battery.  My power supply is limited to the 31v   but at the 31v and 5a houng to the charge controller.. the battery is getting 11 amps so if I could go higher  it might be like 15a instead going to the battery.  Higher voltage    inputs  is better  so either  do a single 24   high voltage panel  or a couple  of 12v in series 5a output panel is good. More is better  lol.  Also with higher voltage  wires can be thinner and still be safe  because they the wont heat up as much.  Nothing wrong with  buying what you can afford  if you can onky afford  a single  12v 5a pannel then get that and get another one later. If you can afford a single  200watt panel then do that. There is just alot of factors at play . If you have  pwm solar charge controller then  you cant do the 24 v panels I  believe and must actually  still to  12v  also  if the pwm is what you are using you are waiting lots of power.  Best of luck!

Question 3

Can I Parallel connect 6 of these 24v panels

Accepted Answer

I don't see why not as long as your charge controller can handle the resulting peak voltage and current ( 1200W ). Make sure it can.

Question 4

wha't the combination of your products including this 200w panel for use with EcoCharger 1300, to max out 65V, 10A?

Accepted Answer

Looks ok, but check with EcoCharger.
