What do Jackery SolarVault fault codes F0 to E7 mean?

Short answer

The SolarVault 3 manual lists codes F0, F1, F2 and E1 to E7 with fixes but no fault names. F0 points to temperature or low charge. F1 to E5 just say restart. E6 covers grid, ventilation or earthing problems, and E7 covers the solar panel inputs, such as polarity or over 60 V. If a code persists, contact Jackery.
