Key Technological Concepts & Product Features

Power Source

• The primary power source is a Power Queen 48V 100Ah lithium golf cart battery.
• Battery monitoring is done via an app, though some instability and jumping in the app interface were noted.
• The battery includes a Battery Management System (BMS) to ensure optimal operation and safety.
• Connected to an EG4 pure sine wave inverter, which converts DC battery power to 120V AC suitable for household appliances like the AC unit.

AC Unit Installation

• Installation uses basic tools: drill, measuring tape, level, pencil, and screwdriver.
• The process involves fitting the AC unit into the window, sealing gaps with siding, and securing the unit for off-grid operation.
• Practical problem-solving is demonstrated, such as adjusting fitment and managing space around the unit.

Power Draw Test & Performance

• The battery successfully powers the AC unit, cooling the space despite no insulation and an open back wall.
• The inverter handles the AC startup surge (~750W) without issue, thanks to its pure sine wave output.
• The AC unit runs quietly and efficiently on battery power.
• Estimated runtime on the Power Queen battery is between 7 to 12 hours for this small AC unit, showcasing practical off-grid cooling capabilities.
