12. Also, the energy meters can be used as traditional
energy meters: Apart form the HAN utility energy
meter, traditional energy meters based on M-bus or
Modbus can be used also by advanced version. To
use the traditional energy meters it is necessary to
make sure that the communication parameters
match in the settings in the GARO Connect app vs.
the energy meter.
NOTE
A load interface can be used in systems with local
production (PV/solar inverters or battery systems). In
such a case, it is important to keep track on the power
direction. This can only be performed using a dual-
direction capable energy meter. Current transformers
on their own cannot provide that information.
13. The load Interface is a part of the total GARO Entity
charging station communication network, that could
be based on either ethernet cable, Wi-Fi mesh or a
Wi-Fi that is part of an existing IT infrastructure. The
GARO Entity Balance basic has 1 RJ-45 Ethernet
port. The GARO Entity Balance advanced has 2 RJ-
45 Ethernet ports.
14. It is always recommended to connect an antenna
even if a Wi-Fi or a mesh Wi-Fi is not used.
15. The short external antenna is supplied with the
product. Use this antenna if the distance to the
charging station is short. There are several factors
that can lower the range of the antenna (i.e.
obstacles, metal cabinet, other radio equipment,
etc.).
16. A long range, panel-mounted, circular disc Wi-Fi
antenna is available as accessory at GARO. It is
used when the distance to the Wi-Fi or mesh Wi-Fi
node ( = other entity unit) is long or obstacles can
occur. Assembly instructions are supplied with the
external antenna. If the load interface is mounted
inside a metal cabinet, it is highly recommended to
use the external disc antenna.
