EM115/GEM120 Grid Meter Installation

EM115/GEM120 Grid Meter Installation

Arrow always points towards the load
CT clamp cables must not be cut down or extended
EM115/GEM120 meters come with a split core CT that has a 2m cable
The communication cable for the GEM120 uses the same communication terminals as the EM115 (Terminal 9 and 10) however, the GEM120 communication terminals are on the opposite side


If you wish to charge from excess solar you will either need a GivEnergy Inverter (see installation confi guration section), or at least 1 EM115/GEM120 (ID1) grid meter installed to monitor the import and export of the building. Every EM115/GEM120 grid meter needs a power supply or voltage reference point.This could be a dedicated supply from a 6A MCB.

This is because excess solar charging can also be achieved via cloud control OR a hard wired Gen 3 inverter. Every EM115/GEM120 meter will need a data connection back to the EV charger’s communication port. The data connection should be via twisted pair cable. (For example, Belden multi-stranded cable or Cat 5/6.)
