Did you add them to your insurance and did you have a big generator for power outages before this installation. Can you run electric heaters or electric over off the cells?
We have a couple of generators that we use from time to time around the farm, but have never used them for the house. Surprisingly, I can only remember the power going out twice in the past 10 years. The last time was a year or two ago when a squirrel made a wrong move on the lines. I gave him a proper burial and the power was restored in less than an hour. You would think with the tornados and tropical weather we get every year that our grid would be less stable, but I just realized that our power company does a darn good job.
We can run anything electrical over at the equipment shed. They installed a breaker box and come outlets over there as part of the job, but it is not directly off the cells. Everything the cells produce goes through inverters and into our main electric wiring.
