Note:
All operating time curves assume permanent installation with the appropriate DC input wire (See the
“Permanent Installation” section of this Instruction Manual) and a full charge on the batteries.
For example, as shown in the above graph, using a 400 A/h battery (batteries), if the average power usage will
be 1000 watts, the operating time will be about 150 minutes. A larger capacity battery will deliver more
operating time between recharges.
Note:
The manufacturer recommends conservative estimates when selecting a battery. More amp hours will
deliver a reserve capacity, and a larger capacity battery will not be subject to deep discharges. Ideally, the
number of amp hours (AH) you expect to use should be less than 50% of the battery’s rated capacity.
Protective Features
LOW BATTERY ALARM
An audible alarm will sound when the 12 volt DC power supply voltage drops down to 10.5 ± 0.3 volts. This
indicates that the battery needs to be charged or there is an excessive voltage drop between the battery power
source and the inverter.
Notes:
It is normal for the alarm to sound when the inverter is being connected to, or disconnected from, a 12
volt DC power source. This does not indicate a problem. However, if this alarm sounds continuously,
discontinue inverter operation and charge the battery before resuming operation. If the voltage drops to
10.0 volts DC, the inverter will automatically shut down. If the low voltage alarm sounds when the battery
is fully charged refer to the “Troubleshooting” section of this Instruction Manual).
CIRCUIT PROTECTION
The inverter has electronic circuit protection against overload or short circuit conditions.
WARNING: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• If turning the ON/OFF Switch OFF then ON again does not reset the inverter, DO NOT ATTEMPT TO OPEN THE
INVERTER. Opening the inverter for any reason will void the warranty. The unit must be returned to Vector
Manufacturing for testing and repair by professional factory technicians.
INSTALLATION
MAXX SST™ inverters will provide you with continuous electrical power when powered by a 12 volt DC source,
such as a vehicle battery or a multiple battery configuration (see the diagram under “Permanent Battery
Configuration Diagram”. This manual does not describe all of the possible configurations.
For optimum operation, the inverter should be placed or mounted on a flat surface; ideally, a normally cool
metal surface to help diffuse the heat that is generated. The cables for Permanent Installation (see the
“Permanent Battery Configuration Diagram”) are not supplied, but will be required to allow for full power
operation and to provide flexibility in positioning the inverter.
