Hadn't thought about using the app because I don't normally carry a cell phone & they barely work at my rural home. Only carry & use my phone away from home and then only for navigating with Google maps. The 24K install is the first step in home upgrade as I must remove the now obsolete super high efficiency 4-ton A/C condensing unit and its companion propane furnace to install my PV system. Later, a new 4-Ton inverter central ducted heat pump will replace the existing ducted system. It will not be as efficient as the old system, but I won't be burning $1,000. of propane each winter. The main reason for the 24K is cooling this summer while everything else is installed then the 24K will become the primary winter heating source. The 4-ton heat pump is mostly to add redundancy, replace old R22 equipment, and add home value. The existing A/C condensing is in the way, it's exactly where I need to install a concrete slab and mount my EP Cube equipment. The PV will be 12.8KW on a 15.4KW EP Cube w/ 39.2KWH of battery. I will collect data on the installed system but for now keeping everybody cool is the priority.
