I HAVE HAD MY INVERTER HOOKED TO 3 STRINGS OF 4 EACH 200 WATT EVERGREEN SOLAR PANELS AND MY SYSTEM HAS WORKED FLAWLESSLY SINCE IT WAS INSTALLED IN 2003. I STARTED WITH JUST 1 SRING OF 4 AND ADDED AS I GOT MY TAX CHECKS EACH YEAR. I HAVE HAD THE TECHNICIAN COME AND CHECK MY SYSTEM EACH YEAR AND HE JUST CLEANS THE ARRAY AND SAYS YOU ARE PUTTING OUT AS MUCH THIS YEAR AS YOU DID LAST YEAR WITH NO PROBLEMS. OUR INVERTER INSTALLATION IS INSIDE AND THE TECH SAID THAT IS THE BEST IF POSSIBLE TO KEEP THE HEAT LOSSES FROM HURTING THE EFFICIENCY OF THE OUTPUT.
