Operation - Technaxx TE16 User Manual

Securely connect the black negative (–) cable lead to the negative (–)
terminal of the battery or power source.
Connect a 0.75mm² wire or larger insulated wire between the chassis
ground connector on the Inverter and a clean electrical grounding point on the
vehicle. This will minimize possible electrical noise interference when using
TVs or radios.
Note: Sparking is normal for first connection.

Do not connect more watt than the Output Power (maximum continuous
watt) of the device (
Determine Total Wattage Required, Watt ratings are usually listed in
equipment manuals or on nameplates. If your equipment is rated in Amp,
multiply that number times AC utility voltage to determine watts.
(Mathematic example: a drill requires 1.5A
problem to use the drill.)
Remember the vehicle's battery will be discharged when the vehicle is not
running.
To Determine DC Battery Amps Required, divide the total wattage
required (from above) by the nominal battery voltage to determine the DC
amps required. 345 Watt : 12V = 28.75A DC.
To Estimate Battery Amp-Hours Required multiply the DC amps required
(from above) by the number of hours you estimate you will operate your
equipment exclusively from battery power before you have to recharge your
batteries with utility- or generator-supplied AC power. Compensate for
inefficiency by multiplying this number by 1.2. This will give you a rough
estimate of how many amp-hours of battery power (from one or several
batteries) you should connect to your inverter/charger.
28.75A DC x 0.5h runtime x 1.2 inefficiency rating = 17.25 amp-hours.
Before using the power inverter determine your
equipment's total watts
see technical specifications).
1.5A x 230Volt = 345Watt. No
