4 Operations
To operate the power inverter, turn it ON by using the ON/OFF switch on LCD remote control and/or the front
panel. The inverter is now ready to deliver 120 Volt power to your loads. If you intend to operate several loads
from the inverter, turn them ON one by one. This will prevent the inverter from having to provide the starting
load for all devices simultaneously.
4.1 Operating limits
Power output: Your inverter is designed to deliver its full output capacity on a continuous basis, and has
a 200% (double) power surge capacity for ±0.3 seconds. The power surge capacity
CANNOT be considered as usable Wattage. It is strictly meant to quickly start the heavy
loads.
Input voltage:
The inverter will operate with an input voltage ranging between 11 and 15 Volt (10 to 15
Volt for the HDi).
Optimum performance is achieved with an input voltage between 12.0 and 14.0 Volt.
If the voltage drops lower than 11.5 Volt (10.5 Volt for HDi), the low battery protection
alarm will sound and battery sign on the remote (when available) will flash.
If the voltage drops below 11 Volt (10 Volt for HDi), ERR LOW code will display on the
remote (when available) and the inverter will shut down automatically. This protects your
batteries from being over-discharged. The inverter will automatically restart when the
input voltage will rise above 13.2 Volt for at least 2 seconds.
The inverter also has a high voltage shut down. If the voltage exceeds 15 Volt, the high
battery warning alarm will sound, the ERR HIGH code will display on the remote (when
available) and the inverter will shut down until the input voltage drops below 15 Volt.
This protects the inverter from excessive input voltage. While the inverter incorporates
protection against over voltage, it may still be damaged if the input voltage exceeds 16
Volt.
4.2 Trouble loads - Television & CB radio interference
CB and television are designed to catch “frequencies” emitted by different devices. Inductive loads such as
electric motors (ex: fridge compressor) can emit a magnetic field strong enough to be interpreted as a signal by
television and CB radios.
If this occurs, the following steps may help eliminate the problem:
 Disconnect all inductive loads while using the TV or the CB Radio
 Move the television as far as possible from your inverter
 Use an extension cord to help dissipate the strength of the magnetic field.
 Make sure both DC battery cables are tied up together as much as possible (from the inverter to the batteries)
