What's your voltage?
Are they approximately 30v panels seriesed up for really high DC voltage?
Since that seems to be the standard for grid tie setups.
I am going 48v for 2 reasons, when one cell gets blocked by a leaf, bird poop or a tumble weed it wont cut the entire strings output in half, just the 1 or 2 panels (if seriesed) that get shaded lose power. Only losing 100 or 200 watts instead of 1 or 2kw if not more.
Then as I add more panels and use less power as I change out appliences for propane or more efficient versions. Then some day production may exceed demand and then I might move in a 5 to 8 ton 48v forklift battery, get stand alone inverters, plus charge controllers and go off grid.
