My original solar array is 660 Watts. It goes back to 2007 when a great deal on panel was $6.60 a watt. The Inverter is a Advanced Energy 1000 Watt inverter that went on line in 2007. The panels are 48 volt 165 watt panels. Advanced Energy inverters were not particularly long lasting and they went bankrupt long ago. So I now have an installed 660 watt array with no inverter. When I wired the array, I figured in for obsolescence and ran the output of each panel to a terminal strip in my basement next to the inverter with #8 cable. This means I have some flexibility on how to rewire the panels.
My thought is the least cost approach are a couple of microinverters. Enphase has a 320 watt version that will accept 48 volt input so that solution would be to rewire the panels two in parallel, This obviously is a small set up so I would want to install the least amount of other components and the least amount of hassle. I do not need online monitoring and would prefer to DIY it. I currently aggregate my three arrays and manually report the total so no need for remote reporting.
So what is the bare minimum least cost microinverter solution?
