Fill the battery during the cheapest overnight slots on Agile or Shape Shifter, or at midnight on Intelligent Go — when grid electricity is at its lowest.
Modern lithium batteries retain the vast majority of energy stored. Real-world round-trip efficiency (inverter + battery) is factored into every saving shown.
Use stored energy during peak hours instead of drawing from the grid at the standard rate. The difference is your saving — real and measurable.
