2.5.3 Transfer
Swift Power Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the
VAC Trip voltage (140 VAC, default setting for 230VAC,90VAC for 120VAC), the inverter automatically
transfers back to the Invert Mode with minimum interruption to your appliances - as long as the inverter is
turned on. The transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds. I t is
the same time from Inverter mode to Standby mode.
Synchronized Power Transfer
When a load is transferred from inverter AC output to another backup AC source of power through the
transfer switch, there will be a finite interruption of power to the load for the transfer to take place. A
mismatch of phase and frequency of the inverter AC output and the backup AC source in transfer is likely to
damage the backup AC source / a reactive load. With sophisticated circuitry design, our inverter will first
lock on the frequency and phase of the input shore power/generator power and make a smooth and safe
transfer at the zero voltage point to minimize the impact on the power modules. Though it is not designed as
a computer UPS system, this transfer time is usually fast enough to keep
your equipment powered up.
Transfer Delay
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the
input terminals to when the transfer is made. This delay is built in to provide sufficient time for a generator
to spin-up to a stable voltage and frequency and avoid relay chattering. The inverter will not transfer to
generator until it has locked onto the generator’s output. This delay is also designed to avoid frequent
switching when input utility is unstable.
2.5.4 Auto Frequency Adjust
The factory default configuration for inverters sold in American market is 60Hz.
If the output frequency needs to be changed this is done by putting in a valid input Power Source to the
inverter’s input lines. Once the inverter validates the input, the output will automatically change.
2.5.5 Power Saver
There are 2 different working statuses for our Global LF inverter:
“Power On” and “Off”.
When the power switch is in “Off” position, the inverter is
powered off.
When the power switch is turned to either of “Power Save
ON” or “Power ON”, the inverter is powered on.
