Support tips for load balancing:
Once you have started the installation guide and added chargers and measurement devices, you need to "configure" them before you can proceed to the next step.
The configuration of the measurement device is not so difficult as the only thing you need to fill in is whether the system has power generators or not. However, when it comes to the charger, we have some settings we would like to clarify.
Installation current limit = Charger fuse
Installation phase mode = 3p if the charger is to be used as 3-phase, or 1p if the charger is to be used as 1-phase.
Installation phase = Phase used by the charger if it is not load balanced and if the installation phase mode is set to 1p. If the charger is set as 3-phase and/or has load balancing, this does not matter and can be left untouched.
Power limit (charger offline) = If the charger or power monitor goes offline, they can no longer communicate. This is a safety setting to minimise the risk of blowing a fuse. It is recommended to be set to half or less of the charger's fuse.
Phase (charger offline) = In offline mode, only one phase is charged. This setting determines which phase.
Settings:
Once the above is sorted out, it is time for the actual load balancing settings. Often there is confusion here - below is a list of what each setting is for and if it is something you should consider.
Phases = The order in which the charger should select phases if the installation phase mode is set to 1p. If it is set as 3p, this setting does not matter but all phases need to be specified, then you can leave this unchanged ("L1,L2,L3").
Max supply current (current meter) = The main fuse in the installation.
Minimum current per charger = How many amps need to be available to start a charging session; should be set to 6A.
Max current per phase (online) = Same as installation current limit, i.e. what the charger is fused with.
Max current per phase (offline) = Same as current limit (charger offline), so should be set to half or less of the charger's fuse.
