Remote Control Figure 6 Apart from the switch panel on the front (or top) side of the inverter, an extra LCD remote switch panel (Figure 7) connected to the remote port at the DC side of the inverter through a standard Ethernet cable can also control the operation of the inverter.
Power Saver There are two different working statuses for our Ultra UL1741 inverter: "Power On" and "Power Off". When the power switch on power switch panel (Figure 2) is in "Unit Off" position, the inverter is powered off. When the power switch is turned to either of "Power Saver Auto" or "Power Saver Off", the inverter is powered on.
Audible Alarm Battery Voltage Low LCD displays "BATT LOW", and the buzzer beeps Allow at least 30CM of clearance around the inverter for air flow. Make 0.5s every 5s sure that the air can circulate freely around the unit. Battery Voltage High LCD displays "BATT HIGH", and the buzzer beeps Variable speed fan operation is required in invert and charge mode.
