System Overrides
By default the solar relay sits idle, you must specify 1 or more overrides in order
to get the unit controlling the load.
•
A maximum of four overrides can be configured.
•
Each override has a start and stop time.
Each override represents a specific mode of operation. There are 6 operating
modes that can be chosen.
Export Control:
In this mode the Solar Relay controls the load based on solar
export levels. This mode is ideal for maximising solar self consumption.
Turn On:
In this mode the Solar Relay will turn the load on for the period of time
specified.
Turn Off:
This mode forces the unit to turn off the load for the period of time
specified.
Top Up:
In this mode the Solar Relay will ensure the load has been on for the
period of time specified. For Example if the Top-up mode is specified to be
between 10pm and 11:30pm (1.5hrs). It will turn the load on if we did not manage
to get 1.5hrs of running time to occur during the day.
This mode is typically used in conjunction with another mode like Export Control
and Voltage / Frequency Control. This mode guarantees a minimum amount of
running time in a 24hr period.
Voltage Controlled:
In this mode the relay will turn the load on and off based on
Grid Voltage. This mode is best suited for helping to manage voltage rise issues at
a solar installation.
Frequency Controlled:
In this mode the relay will turn the load on and off based
on grid frequency. This mode is ideal for operating in Off grid environments where
frequency shifting is used to control devices. Systems such as SMA use frequency
control in their off grid environments.
