Greetings. I have been browsing for a couple days, and have not yet settled on the right panel. Looking to purchase two 200-watt mono panels to couple with a Westinghouse iGen 1000s. Max input is 400 watts. Looking for some pretty decent efficiency at a reasonable price. Connecter size is 8MM. I plan to keep this system as backup in case of a long-term grid failure. Also have a couple generators if needed in case of snow, etc. Was hoping y'awl could offer some input. Thanks in advance.
