Video Summary: “Off Grid AC – DIY Window Install and Power Draw Test”
This video provides a hands-on DIY guide and review focused on installing a window air conditioning (AC) unit powered off-grid using a portable battery system. It covers key technological concepts, product features, and performance analysis.
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.
