Manual-start and electric-start generators typically do not have self-
protection features to shut down the generator in the event of low oil
pressure, over-heating, overcranking, etc., and, therefore, are not designed
for unattended starting and operation.
If using a manual-start or electric start generator, be sure that the
generator is located where it can be easily accessed to be started.
Auto-start
generators
When using an auto-start generator, the generator is connected to the
inverter AC2 input. The inverter controls the operation of the generator
with the assistance of the optional GSM. Auto-start generators are
equipped with terminals for signal wires to be routed and connected to a
remote switch/relay (a "dry contact") to signal the generator to run and/or
stop.
Auto-start generators are equipped with self-protection features to disable
starting and/or to shut down a generator in the event of low oil pressure,
over-heating, overcranking, etc. When generators are equipped with these
protection features, they are designed for unattended starting and
operation and may be compatible with the Sine Wave Plus with the
optional GSM.
Be sure to locate an auto-start generator in a place protected from
extremes of temperature so it can successfully start and operate without
assistance.
Starting
requirements
The generator can be set to start based on four different, user-specified,
scenarios with different requirements for each:
• battery voltage
• inverter load current
• time of day
• exercise time
If used with an application that includes utility power, the generator will
be started only if utility power is not available, as it is not possible to use
both generator and utility power at the same time (except for the
scheduled exercise time).
It is safe for both the utility and generator inputs to be energized at the
same time, although the inverter can only take power from one source at
any given time.
Important:
The automatic generator start feature of the Sine Wave Plus can
only function on generators equipped with two- or three-wire auto-start operation.
Most auto-start generators have this feature. Check with your generator supplier
and make sure this feature is available. Additional hardware may be required.
