Grid Use Time
The Grid Use Time function allows the system to connect to the utility grid and disconnect from it on a
timed schedule.
Grid Use Time
mode is programmed separately for weekday and weekend connect
times. Only one Grid Use Time may be programmed on a weekend. Three Grid Use Time periods may be
programmed on weekdays.
Before turning the Grid Use Time mode on, set all weekday and weekend time periods.
IMPORTANT:

Care must be taken when programming weekday and weekend times that encompass USE
periods past midnight (12:00 a.m.). The user must take into account weekday USE periods that
will end on a Saturday.

Grid Use Time should not be used if HBX mode is used (see page 127). These functions have
incompatible priorities and will conflict with each other.

The time and date must be accurately programmed for the Grid Use Time mode to function
properly.

The MATE3 does not automatically adjust its clock for Daylight Savings Time. This may affect
timing of grid usage.

If a start time equals a stop time, no action will be taken and the time period is ignored.

If the battery voltage falls below the inverter’s Low Battery Cut-Off voltage, the inverter will
automatically connect to the AC input source regardless of the time-of-day setting.
Example #1:
Weekday Start - 6:00 p.m. Weekday Stop - 6:00 a.m.
Weekend Start - 12:00 a.m. Weekend Stop - 12:00 a.m.
The weekend USE period has been left at its default (12:00 a.m.). Any time that a Start time equals a
Stop time, no action will be taken and the time period is ignored. The above settings will have the
following results:

Monday–Friday evenings at 6 p.m., the MATE3 issues a USE command to the inverter allowing the
AC input source to be used.

Monday–Friday mornings at 6 a.m., a DROP will be issued.

On Friday evening at 6 p.m., a
USE
is issued but since the Weekend Start and Stop times are equal, the
weekend use time is disabled; no DROP will be issued until Monday morning at 6 a.m.
Example #2:
Weekday Start - 6:00 p.m. Weekday Stop - 6:00 a.m.
Weekend Start - 4:00 p.m. Weekend Stop - 8:00 a.m.

Monday–Thursday evenings at 6:00 p.m., the MATE3 issue a USE command to the inverter allowing
the AC input source to be used.

Monday–Friday at 6:00 a.m., a DROP is issued. On Friday evening at 6:00 p.m., a USE is issued.

Saturday morning a
DROP
command is issued at 8:00 a.m. Saturday afternoon at 4:00 p.m., the
inverter will USE again until Sunday morning at 8:00 a.m. Sunday evening at 4:00 p.m., a USE time
period will start, ending on Monday morning at 6:00 a.m.
