Auto Frequency Adjust; Power Saver - Ultimate Power UP1200PCUL User Manual

3.4 Auto Frequency Adjust

The inverter is designed with Auto Frequency adjust function.
The factory default configuration is 60Hz for 100/110/120VAC inverter
While the output freq can be easily changed once a qualified freq is applied to the inverter.
If you want to get 60Hz from a 50Hz inverter, just input 60Hz power, and the inverter will automatically adjust the output
freq to 60Hz and vice versa.
NOTE: The inverter will output factory set freq after it restarts. Customers who can only accept one freq should
specify the freq when ordering.

3.5 Power Saver

There are 2 different working statuses for UL inverter: "Power
On" and "Power Off".
When power switch is in "Unit Off" position, the inverter is
powered off.
When power switch is turned to either of "Power Saver Auto"
or "Power Saver Off", the inverter is powered on.
Power saver function is dedicated to conserve battery power
when AC power is not or little required by the loads.
In this mode, the inverter pulses the AC output looking for an
AC load (i.e., electrical appliance). Whenever an AC load
(greater than 25 watts) is turned on, the inverter recognizes
the need for power and automatically starts inverting and
output goes to full voltage. When there is no load (or less than 25 watts) detected, the inverter automatically goes back
into search mode to minimize energy consumption from the battery bank.
In "Power saver on" mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is
significantly reduced.
The inverter is factory defaulted to detect load for 250ms in every 30 seconds.

Note:
The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
