Battery Use
•
To avoid over-discharging your vehicle battery, we recommend running your engine for 10-20
minutes to recharge the vehicle's battery if battery voltage drops <11V.
•
To properly size your battery, use the following formula: Volts * Amps = Watts or Watts/Volts
= Amps. Example: 1000 watt inverter / 12 volts DC = 83.3 DC amps. In this example, you will
need 83.3 amps to power a 1000 watt load for 1 hour. If you need to power 1000 watts for 2
hours you will need 83.3 * 2 = 166.66 DC amps available. A 100 amp hour battery will give
you 100 amps / 166.66 = .6 hours so you will need two batteries if using 100 amp battery.
This is if you fully deplete your batteries. We do NOT recommend fully depleting your
batteries. This is just an example. Your power requirements may be different.
•
If you choose to use a female 12 Volt DC adapter for your inverter or to the inverter make
sure wire size is correct.
•
IF YOU CONNECT THE WIRES TO THE INCORRECT TERMINALS, YOU WILL REVERSE THE
POLARITY AND DAMAGE THE INVERTER.
•
REVERSED POLAR ITY WILL INSTANTLY VOID THE WARRANTY OF YOUR INVERTER, SO BE
CAREFUL TO CONNECT YOUR INPUT WIRES PROPEPLY.
•
If you choose to operate a battery charger to replenish your battery’s voltage, be sure to
check with charger manufacture before damaging the charger.
•
CONNECTING THE INVERTER INPUT TO A BATTERY CHARGER WILL VOID THE WARRANTY, AND
MAY DAMAGE THE INVERTER.
•
Make sure that the battery voltage does not exceed 15 volts DC.
•
CONNECTING THE INVERTER TO A DC POWER SOURCE GREATER THAN 15 VDC WILL VOID
THE WARRANTY, AND MAY DAMAGE THE INVERTER.
Cables
We recommend that you refrain from using battery cables longer than 12 feet
between the DC power source and the DC input of the inverter. Longer battery cables
on the DC input will create a voltage drop which results in a reduction of efficiency
and output. If you require more than 12 feet, use a bigger cable. We recommend
using an extension cord between the AC output and AC appliance. You may use up to
100ft, high quality extension cord. A longer cord may result in reduced output. See
Specifications chart for recommended battery cable size.
Measuring The AC Voltage
The output waveform of the inverter is a MODIFIED SINE WAVE. If you choose to
measure the AC output voltage, you must use a TRUE RMS MULTI METER. Using any
