This document provides essential safety, operation, and maintenance information for the Tesla Powerwall 2 AC. It is intended for use by owners and must be read in its entirety before operating the system. Installation and repairs must only be performed by Tesla Certified Installers.
Safety Instructions
- High Voltage: Installation and service require knowledge of high voltage electricity.
- Heavy Equipment: Powerwall is heavy; use lift equipment.
- Chemical Exposure: Contains lithium and cobalt compounds. Do not open the external casing.
- Environmental Limits: Do not install near heating equipment, in direct flame, or where flooding is possible. Ensure no water sources are above or near the unit.
- Prohibitions: Do not immerse in water, insert foreign objects, paint the unit, or connect directly to PV solar wiring.
Operation
The Powerwall is controlled by the Gateway via the Tesla app. The Powerwall On/Off switch should remain in the ON position during normal operation. Do not operate the unit unless all covers are in place.
Troubleshooting
If the system is unresponsive, check the LED status on the right side of the Powerwall:
- Solid: Enabled/Communication with Gateway.
- Flashing: Enabled/No communication with Gateway.
- Pulsing: Enabled and charging/discharging.
- Off: Not enabled or switched off.
If the system is unresponsive, perform a power cycle: turn off the Powerwall, turn off the AC breakers for the system, wait one minute, turn the breakers back on, and turn on the Powerwall.
Emergency Procedures
In case of emergency, contact the fire department or emergency services first. If safe to do so:
- Fire: Turn off Powerwall and AC breakers. Use water, CO2, or ABC extinguishers. Avoid type D extinguishers.
- Flooding: Stay out of water if the unit is submerged. Turn off Powerwall and AC breakers.
- Coolant Leak: Avoid skin contact. Ventilate the area. Use absorbent material like cat litter to clean spills.
Maintenance
The system requires no pre-scheduled preventative maintenance. Keep the unit free of debris, especially around air intake and exhaust vents.
Practical help
Common problems
Check home internet connection. If still unresponsive, perform a power cycle: turn off Powerwall, turn off AC breakers, wait 1 minute, turn breakers on, then turn on Powerwall.
