As you may have read in some of my past questions/postings, I'm gathering different sizes of new and used panels, as I find them at low prices, for a future small array. All are 12 volt, but will be charging a 48v battery bank.
So far, I have four 75 watt (used Siemens), two 90 watt (new China), four 100 watt (new China), and two 120 watt (used American Signal).
If I add two more 90 watt panels and two more 120 watt panels, then I can have four strings at 48v.
As I understand it, mixing different wattage panels within a series string will only lower the output. Do I understand THIS correctly: If I parallel four 48 volt strings, a 75 watt string, a 90 watt string, a 100 watt string, and a 120 watt string, then I won't lose any watts?
I have a new 60amp, Tristar PWM controller. For the money (under $200), will this work with the four strings?
Also gathered an old stock, but new 1500 watt PSW Aimes inverter designed for 48v input and 120v output. ($175) and a 500' reel for single run #6 multi-strand copper wire ($85)
I've checked the amps on the 75 watt panels and they range from 4.5-4.8. I would expect the others to perform at their ratings.
