Operation
Page 66
Send at least every 15 seconds the SIO command
HYBRID or Modbus address 42002 Hybrid to the
EFOY Pro fuel cell.
The operation mode “Hybrid” will be displayed and
the open padlock will be displayed at the bottom
right of the display.
To start and stop the EFOY Pro fuel cell a positive
voltage signal must be connected to Pin 7 (Remote
On) or via software SIO command REMOTE ON/OFF
or Modbus address 41030 (see chapter 5.5.5 Re-
mote On / Off, page 64).
The battery voltage will not exceed the set value
switch-off voltage (Hybrid). If the voltage signal on
pin 7 or the “Remote ON” software commands is
continuous, the EFOY Pro fuel cell will charge the
battery continuously in full and part load mode as
a constant voltage (CV) charger.
Automatic antifreeze feature
The device has an intelligent automatic
antifreeze feature. This operating status
switches on automatically as soon as the
temperature drops below +3 °C / +37.4 °F.
This prevents the device from freezing. If
the device is operating in antifreeze mode,
the message "Antifreeze" is shown in the
second line of the display.
CAUTION!
The automatic antifreeze feature only works when the fuel cell is
connected to a filled EFOY fuel cartridge and an intact battery.
For a five-month winter period in Central Europe, the device re-
quires approx. 10 liters / 2.64 gallons of methanol in antifreeze
mode.
CAUTION!
Charging Lithium (LiFePO4) batteries is not always possible at
temperatures below 0 °C. The instructions from the battery
manufacturer must be observed.
