MICROPROCESSOR BASED
Dometic SINE WAVE INVERTER SI-1500 SERIES
ENABLING AND DISABLING POWER SAVING MODE
7-2-1. When an inverter is powered on and is running in idle condition
(there is no load or the load connected to the inverter has been
switched off), it will still draw some power from the batteries for
keeping the system alive.
7-2-2. This inverter features a power saving " sleep " mode for
conserving the battery power during idle conditions. When this
mode is enabled, the inverter senses the output power being
drawn and if this is less than 2 to 15 watts, the inverter shuts
down the output power. Only essential systems are kept alive
to reduce power consumption from the batteries to a very low
value of only about 1.5 watts. As soon as a load is switched on,
the inverter wakes up from its "sleep" condition and restores
the output power after a response time of about 8 seconds.
Please note that on waking up from the power saving "sleep"
mode, the inverter requires some time to prepare all the
systems before it can start delivering power to the load. Hence,
the output power will not be available immediately but after a
time lag of approx. 15 to 18 sec. If using a hand tool or other
appliance with a trigger, keep the trigger pressed for some time
till the power is available to drive the tool / appliance.
7-2-3. The power saving " sleep " mode can be enabled or disabled
with the help of the power on / off switch or with the help of the
optional remote control. Procedure to switch between the two
states is given at paragraph 7.2.6 below. The inverter has been
factory pre-set in the enabled condition.
