solar and inverters and batteries

I am working with a local Batteries Plus dealer to find the right mix for a solar project. It appears that Gel cells or AGM sealed batteries are the best. We are going to gang one or two batteries together 35 amp hour or so and hook them into a UPS to extend the life of the power back up. I will keep you posted. Next step is to try this method with a solar/inverter arrangement. Call me or e-mail if yu want to discuss this further.
