New to the forum. Retired Navy Aviation Electrician with 25 additional years in automotive electrical systems - enough knowledge to be dangerous..
I've had a basic (very basic) understanding of solar for a few years having a simple 100 watt panel maintaining 6 old Trojan T105 batteries. Fast forward to today where I am putting together a 1200 watt "back-up" system for when a hurricane takes us temporally off grid - no intention of tie-in to the grid. Here's a basic list of components on-hand:
6 KOSTA 200-12 (see attached label for specs)
1 MPPT 60-amp Charge controller (12/24 volt)
1 50 amp sub-panel
1 "Rapid Shutdown" NO relay (12-volt continuous duty 500 amp+ sustainable)
1 AIMS 3K Pure-Sinewave Inverter (older unit I've had for years)
6 New Trojan T105 6 volt batteries wired in series-parallel resulting in 12 volts and a massive amount of AH.
Plus a myriad of small parts. The panels will be roof mounted using Super Strut racks and fastening hardware.
No doubt I've left out something I should have mentioned - I am providing some pictures to offer a visual.
I am generally pretty handy with mechanical and electrical but I absolutely suck at math and what I'm trying to figure out is what voltage/current I can expect coming down the "pipe". I find a lot of info on the net regarding pros & cons of series OR parallel configurations but very little on series-parallel setup. I think I want to go with the series-parallel configuration but don't know how to compute the results. You can offer me the formulas but I'm probably too dumb to figure it out.
