VertaMax User Manual
Revision 1
IMPORTANT:
Do not turn on all AC products at the same time and be sure to turn on the largest
power product first.
IMPORTANT:
In the ON position, even if no loads are connected, there is a low current draw
(<0.8A).
3.1.2
Power OFF
From the AC Output end of the inverter, switch the rocker power switch to the OFF position to
shut down the Inverter completely, preventing it from drawing power from the batteries. The green
power indicator will go out.
This will also “reset” the unit if it shuts down due to low battery or overload.
3.1.3
USB Power Port
The VertaMax is equipped with a USB charging port, that will deliver 5 volts at a maximum
current of 2.1 amps. This port can be used to conveniently charge all standard USB accessory
items; eg: cell phones, portable speakers, etc.

ROTECTION
–
A
LARMS
The VertaMax has several protection features to protect itself as well as your electrical system.
3.2.1
Over Input Voltage
When the DC INPUT power voltage exceeds 16V DC, the alarm will beep three (3x) times and
the FAULT LED will blink Red.
The inverter will automatically shut down to protect itself from excessive input voltage.
IMPORTANT:
Although the inverter incorporates protection against over-voltage, it is still
possible to damage the unit when the input voltage exceeds 15V DC.
3.2.2
Low Input Voltage
As a battery is used, its voltage begins to decrease. When the inverter senses that the voltage at
its DC input has dropped to 10.5V ± 0.3 DC, an audible alarm will sound and operation will
remain normal. When this happens, it is important to remove or shut down computers or other
sensitive devices that may be connected to the VertaMax and recharge the battery before its
capacity drops too low. The inverter can operate while the battery is recharging.
If the audible alarm is ignored and the voltage drops to 10.0V DC, the alarm will beep three (3x)
times, the FAULT LED will blink Red, and the inverter will automatically shut down to protect the
battery from being over-discharged.
When the input voltage rises to approximately 11.4 – 11.9V DC, the inverter restores to normal
operation and the red FAULT indicator will turn off.
3.2.3
Power Overload
When the starting power exceeds the rated surge power or the AC appliances connected to the
VertaMax exceed the inverter’s power rating, the alarm will beep continually and the FAULT LED
will blink Red. The output voltage will decrease and the inverter will automatically shut down after
approx. 20 seconds.
When in over current protection mode, the inverter cannot automatically restore to normal
operation; reset to normal operation by using the manual power switch.
3.2.4
Over Heating
After continuous use the inverter case temperature will rise to ~60
o
C. When the inverter exceeds
a safe operating temperature, due to insufficient ventilation or an increase in ambient
temperature, the alarm will beep two (2x) times and the FAULT LED will blink Red. If the over-
temperature condition persists, the inverter will automatically shut down.
Should this occur, place the inverter in a well ventilated, dry place, with a distance of at least 7”
(20cm) from any objects. The ambient environmental temperature should not exceed 40
o
C.
The inverter's cooling fan(s) are temperature controlled and only activate when the inverter is
approaching an unsafe operating temperature
