Key Functions
Storm Hedge
When the Storm Hedge function is enabled, the FranklinWH App will receive a weather
forecast from the local authority about a serious weather event, send a warning message
via the app. Then the FranklinWH system will automatically enter emergency backup mode
to power household loads during the weather event. When the extreme weather passes,
the FranklinWH system will automatically revert to the previous settings.
The Storm Hedge function may be enabled under both the Self-Consumption and
Time of Use modes.
Emergency Stop
In an emergency, manually turn off the external Emergency Power Off (EPO) switch, if
installed. Otherwise remove the EPO plug. The FranklinWH system shuts down after the
EPO is triggered.
After the emergency shutdown, the home will lose power. When the
emergency issue has passed, reset the EPO switch/plug to restore home power
supply.
On-grid to Off-grid
When the grid fails or is abnormal (for example, under-voltage “brownout,” overvoltage, or
abnormal frequency), the FranklinWH system automatically switches to the off-grid mode.
When off-grid, the solar, generator (if connected) and FranklinWH system will power the
household loads.
Off-grid to On-grid
The FranklinWH system automatically switches to the on-grid mode when the grid is
restored. The grid, solar system, generator (if connected) and FranklinWH system will
power the household loads.
