Smappee EV Wall – Installation manual - English
Installation in distribution panel
This chapter describes the installation of the Infinity components in the distribution panel. These
components enable overload protection & solar optimization supplied with the EV Wall.
The EV Wall package comes with the required Smappee Infinity components to be installed in the
distribution panel to measure the main feeder (total grid consumption) and single-phase solar
production. If three-phase solar is present, the EV Wall Solar Add-on can be purchased.
Depending on the EV Wall type (1-phase or 3-phase), the included Smappee Infinity components
varies:
o EV Wall 1-Phase:
▪ 1 x Connect
▪ 1 x CT Hub
▪ 3 x CT 50A (1x grid + 1x solar +1x EV measurement)
▪ 1 x EV Wall splitter
o EV Wall 3-Phase:
▪ 1 x Connect
▪ 1 x CT Hub
▪ 4 x CT 50A (3x grid + 1x solar measurement)
▪ 1 x Solid Core 3-Phase CT (EV measurement)
▪ 1 x EV Wall splitter
If additional CT measurements need to be added, standard Infinity hardware (CT Hubs and
CTs) can be purchased and installed in addition to the EV Wall components.
Always keep the Smappee Infinity installation guidelines in mind.
For installation of these components, please refer to the diagrams on the next page.
The main installation steps include:
a. Install the 32 A circuit breaker (not supplied) according to local regulations. In case of a three-
phase EV Wall: install the supplied solid-core CT together with the circuit breaker.
b. Install the CTs as indicated on the diagrams on the next page. Connect these to the supplied CT
Hub.
c. Install the Smappee Connect and EV Wall splitter. The Smappee Connect should be placed inside
or near the distribution panel. It requires a stable internet connection via Wi-Fi or Ethernet.
d. Connect the A- and B-bus cables as indicated on the diagram. Connect the Cat 5/6
communication cable to the RJ45 port of the splitter.
Ensure that the CT Hub(s) are connected to the A-port of the Smappee EV Wall splitter
and the Smappee Connect to the B-port of the Splitter. Also check that the Cat 5/6
communication cable is connected to the splitter and NOT to the Smappee Connect.
