Advanced System Calculator V5.1.1 System Calculator In this section add the values from your electric bill, from the past 12 months, using the two highest values you see in kWh and kW. Monthly Usage (kWh): Will give you the "Storage" you need to make it during a power outage, and is based on a 24-hour period. Monthly Usage (kWh): Will also give you the correct Solar PV size in kW, the calculations Peak Demand (kW): Will give you the "Power" you need to make it at the first hit of a power outage, as this will take care of the biggest hit of the load. Battery Models: This is a drop-down giving you three system models to choose from. Guardian Elite, the Guardian E2.0, and the Guardian Tower. Best Arbitrage Unit: "Guardian Elite" Best Partial Unit: "Guardian Elite / Guardian E2.0 for longer storage" Best Whole-Home Unit: "Guardian E2.0 / Guardian Tower for loanger storage" System Type Battery Only Solar + Battery Monthly Usage (kWh) Peak Demand (kW) Battery Model Guardian Elite Prime (16kWh/15kW) - $15,275 Guardian E2.0 (42kWh/15kW) - $27,373 Guardian Tower (96kWh/15kW) - $32,210 Solar System Size (kW) Calculate System
