GoodWe ET G2: switching the system (inverter + battery) off and on in a safe order
De-energise the system before any work and wait the time on the label. The manual gives the power-off order and how to restart the battery.
What the GoodWe ET G2 indicators mean (power, BACK-UP, communication)
The indicators show power, self-check, grid operation, back-up output and communication states, as described in the manual.
