Powerwall Inverter Adjustable Settings - Tesla Powerwall 2 AC Installation Manual

The Powerwall inverter has the following adjustable settings, which are determined when the
system is commissioned.
NOTE: Under abnormal voltage or frequency conditions or in response to a detected
unintentional island, the system will disconnect from the grid by opening its internal contactor.
NOTE: All values are for factory default 240 V @ 60 Hz.
Voltage Ride-Through
The Powerwall inverter has three voltage and time set points for low voltage ride-through,
configurable to the following ranges (measured as line to neutral for single-phase, and line-to-
line for split-phase):
Parameter
LVRT Point 3 0-400 V
LVRT Point 2 0-400 V
LVRT Point 1 0-400 V
LVRT Point 0 0-400 V
*Voltage accuracy 2% of nominal
The inverter has three voltage and time set points for high voltage ride-through, configurable
to the following ranges (measured as line to neutral for single-phase, and line to line for split-
phase):
Voltage
Parameter
HVRT Point 3 0-400 V
HVRT Point 2 0-400 V
HVRT Point 1 0-400 V
HVRT Point 0 0-400 V
*Voltage accuracy 2% of nominal
The above tables represent the maximum parameter values that the user can input. However,
240 VAC nominal systems are limited to a maximum HVRT of 120%.
The inverter ships with the pre-defined settings listed below.
