IF THE GENERATOR RUNS MORE OFTEN THAN
NORMAL OR ExPECTED:
There are several possible causes:
1.
The system average load has increased:
Using SP LINK check the
“7 DAY DAILY
AVERAGE”
figure in the
“AC LOAD ENERGY”
section of
“AC HISTORY”
within the
“DATA VIEW”
tab and compare it with the value displayed when
the system was operating satisfactorily.
Using SP LINK compare the
“7 DAY DAILY
AVERAGE”
figure in the
“AC LOAD ENERGY”
section of
“AC HISTORY”
within the
“DATA VIEW”
tab against the system design value which should
have been supplied by the installer.
If loads have significantly increased identify any
new electrical equipment that has been added
2.
The system peak loads are very high:
Using SP LINK check the
POWER
and the
POWER
(5 MIN AVERAGE)
in the
AC SOURCE
area in the
NOW
tab of the
DATA VIEW
section
while operating any new appliance that has
been added to the system. The associated On
5 minutes power and the On 15 minutes power
setting in the
GENERATOR AUTO RUN TAB
may
need adjustment by your supplier.
3.
The load during late night and early morning
periods is higher than expected but not
high enough to keep the generator running
permanently. There may be multiple starts and
stops as the battery becomes discharged and is
partly recharged:
Increase the generator minimum run time to
increase the amount of battery recharge before
stopping hence reducing the number of starts
and stops.
4.
The battery is not operating correctly (see 9.5
Battery Problems).
If the generator runs longer than normal or
expected:
This is generally because system load has
increased or the renewable input from solar has
decreased. It could also be because the battery
efficiency has fallen off with age or cell failure in
the battery.
Use the event log to establish load levels and
reasons for generator starts and stops.
Use the Data View menu to check measured
values, particularly the accumulated battery
energy in and energy out totals. These will have
to be compared over a week to see the change in
the accumulated values.
It may be doing an Equalise charge which can take
some hours to complete; check if the Equalise LED
is illuminated.
There may be a sustained load on the system.
Check to see that appliances have not been left
on. The Now, Today and AC History sections of the
Data View tab provide information regarding the
load power.
Check the generator schedule settings.
If the generator restarts a minute or so after it last
stops then the battery is discharged, the battery
volts are low or a load is present. Check the
Now section of Data view to see the Generator
Running Reason. You can shut the generator
down permanently by setting the generator to NOT
available.
