Also tested : to see if a cell modem would work. As it turns : out we have a just good enough signal with : Verizon :) I worked with Ryan and he was able to : set up the modem remotely. I will have to : return to install four 100AH batteries. It was : pretty hot and humid, it was only 102 but the : heat index made it feel like 108. Thunderstorms : in the area.
