Your Smart Energy
Set the time and days for switching on like the following figure. You can set one or two
time periods. In the set periods the Aux contact will be switched on, outside the set
periods the Aux contact doesn't work.
If the two periods overlap, only the first period will be active. In this mode the normal
self-consumption logic will be used.
b. Control Mode Off
Set the time and days for switching off like the following figure. You can set one or two
time periods. In the set periods the Aux Contact will be switched off. If you don't set
the period the function doesn't work.
If the two periods overlap, only the first period will be active. In this mode the normal
self-consumption logic will be used.
In this mode the normal self-consumption logic will be used.
c. Control Mode Auto
It means the Aux contact will be switched automatically on and off according to the
following logic.
Under Auto Mode, the period control function doesn't work. In this mode the following
further specifications should be set.
c.1 You can set the SOC to activate. There are three modes can be set:
1. "≥", namely when SOC ≥ given value, it works.
2. "≤", namely when SOC ≤ given value, it works.
3. "disable", namely the Aux contact control is not related to the SOC value.
c.2 You can also set surplus energy range, namely the feed-in condition.
Set the feed-in power values as the following figure.
When the feed-in power > left given value, the Aux contact will be switched on.
When the feed-in power < right given value, the Aux contact will be switched off (or
back to the initial situation).
