Using Search Mode
Why use Search
mode?
Search mode allows the inverter to selectively power only items that draw more
than a certain amount of power, which can result in power savings.
The Conext SW has a no-load power draw of about 38 W (SW 2524 120/240) and
40 W (SW 4024 120/240). Enabling Search mode reduces this power draw to
less than 8 W for all models.
Single units When a single Conext SW has Search mode enabled, the inverter sends
electrical search pulses through its AC output. These search pulses search for
connected AC loads. The delay between search pulses is set using the Search
Delay setting.
After a load larger than the Search Watts setting is detected, the inverter
turns on.
When to set up
Search mode
The Search mode feature is only valuable if the inverter can spend a couple of
hours “sleeping” each day. Therefore, if Search mode is to be used it must be
adjusted properly. The initial adjustment should be made so that the inverter
comes on only when needed.
Certain types of loads can cause Search mode not to work as expected. These
types of loads are described on “Problem Loads” on page 5–3 of the
Troubleshooting chapter. If these kinds of loads are in the system, follow the
suggestions given to eliminate the problem. If the problem loads cannot be
eliminated, there are two work-around solutions:
1. Disable Search Mode from the main Conext SW Setup menu, causing the
inverter to always remain at full output voltage.
2. Use a search-friendly companion load whose only purpose is to be switched
on to wake up the inverter to power the load that is unable to bring the
inverter out of Search mode.
Using Inverter Block
The Inverter Block feature halts inverter function for a period of time each day.
This period of time is defined by the Inv Block Start and Inv Block Stop
settings. Inverter Block allows you to control which time period is not ideal for
inverting. This can be a time period when conserving battery power is more
important than running loads.
NOTES:
• Search mode, by function, cannot work with clocks and timers or devices
that need power 24 hours a day. Examples of devices with timers include
video recorders, coffee makers with brew timers, refrigerators, and freezers
with defrost timers. Examples of devices that need power 24 hours a day
include telephone answering machines, alarm systems, motion detection
lights, and some thermostats.
• When the inverter is searching the output for loads, lights that have a
wattage lower than this setting may flash momentarily.
