Solar Panels Brands - does it matter?
I am looking to buy 200-300 watts of solar panels to charge 200-240 ah of battery storage. Researching panels on the web, it seems that prices for solar panels have a very wide range. Putting aside ...

See pages one and two. I stand corrected regarding Nominal Maximum Input Power Ratings as it relates to battery volts and not PV panel array volts. However, I also stand by my assertion that a TS-MPPT-45 will work well with two 300 watt, 24 volt panels. Again, at nominal 12 volts (batteries or system) the maximum PV array input rating for the TS-MPPT-45 is 800 watts when using Normal Operating Cell Temperature ratings which is more like real world conditions than the standard test. And in those real world conditions it is likely that one would never approach the Maximum Solar Open Circuit Voltage of 150 volts DC. I agree with scroller95969 that the Morningstar specifications are confusing.
