9-2. Power saving mode
MICROPROCESSOR BASED SINE WAVE INVERTER S-1500 SERIES
ENABLING AND DISABLING POWER SAVING MODE
9-2-1. 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.
9-2-2. 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.
9-2-3. 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 para
6 below. The inverter has been factory pre-set in the enabled
condition.
9-2-4. Power saving “sleep” mode, enabled
9-2-4-1. The front plate has a green led marked “power saving” for
indication of enabled state of power saving “sleep” mode
(here-in-after referred to as the green led)
