2.2 Recommended upstream breaker and input cable
To reach stable system operation, it is very important to use proper input cable and upstream breaker.
Recommended values for different types of networks can be find in table below.
AC Mains Type
230/400Vac
3-phase, TN-S network
5-wire system
230/400Vac
3-phase, TT network
4-wire system
230Vac
3-phase, IT/TT network
4-wire system
!!! WARNING !!!
System is designed to operate on 1-phase or 3-phase networks. It is strictly forbidden to
connect multiple single-phases to the system.
CAUTION:
For TT-networks, the installation of an RCD is required.
NOTE:
If different number of power shelves or breaker with lower rating needs to be used from any reason,
discuss possibilities with Pixii.
NOTE:
Breaking capacity of input breaker installed in system is 10kA, upstream breaker breaking capacity
must correspond to AC grid conditions at the point of installation.
NOTE:
Cable type, upstream breaker and RCD depends on local conditions and regulations.
2.3 Mains input metering
To secure correct operation, system must have actual readings from mains input AC meter. Therefore
compatible meter must be installed on site. Measured values are important to perform autonomous
operation functionality such as peak shaving and others. Pixii system has support for communicating
with 2 different types of meters.
NOTE:
Measured data are used at the customer's own risk. The distribution company or Pixii is not responsible
for any losses resulting from its use, including losses due to errors or omissions in the data.
2.3.1 AMS energy meter
AMS meter allows for monitoring consumption and production down to a few second intervals through
the HAN-port (M-Bus) according to Norwegian HAN-port specification. The HAN-port is closed by
default. Contact your local network company to open it. Before opening the HAN-port, the network
company will first ask some questions related to securing the gate for privacy reasons. For connecting to
the HAN-port a standard Ethernet cable with RJ45 connectors is required. Maximum practical distance
at highest speed is 350 meters.
