Caution: Detailed schematics for installing METRON Dynamic Power Control system are located in a
separate installation manual, intended for qualified installers only.
Dynamic Power Control (OPTIONAL for “+” models)
All “+” charging stations can be equipped with
METRON Dynamic Power Control system
that is always
monitoring the load at house main fuse with electric current sensors and dynamically adjusting (lowering
or rising) the charging current/power of your electric vehicle in the way the main house fuse never gets
overloaded (never blows-up). If the house has a solar (or wind/hydro) power plant installed this system
allows
higher current/power charging than would be allowed by the main fuse
and it also enables the
possibility of user activated
solar SURPLUS charging
what means the vehicle will be charged only with
excess solar power without taking any energy from the grid. METRON Dynamic Power Control system is
designed to work with
1-phase and 3-phase
power systems.
To be short, METRON Dynamic Power Control system enables users to charge their electric vehicle
without worrying about the load other household appliances might draw from the in-house grid.
There are 3 options for installing Dynamic Power Control system (main fuse protection):
A) If there is 1 charging station in the house the current sensors can be installed at main fuse location
and hardwired to the charging station.
B) If there is 1 charging station in the house and it’s not possible to hardwire the current sensors all the
way to the charging station, the current sensors can be connected to additional locally installed
METRON Dynamic EV Charging Unit (model 3FD-2)
that is sending data wirelessly to the charging
station.
C) If there are 2 or more charging stations installed in the house and powered from the one main fuse
only wireless Dynamic Power Control system can be established. All you need is 1 pcs METRON
Dynamic EV Charging Unit (model 3FD-2) and current sensors. This way up to 30 charging stations
can be controlled and main fuses with rated current up to 250A are supported.
Note: Wireless signal has an open-air space range of 500m with buint-in antenna and up to 2000m with
additional antennas on the METRON Dynamic EV Charging Unit (model 3FD-2) and also on the charging
station. If the system is installed within one house usually no additional antennas are needed.
