1. Make sure that the chassis ground screw on the rear of the inverter is solidly
connected to the ground system of your vehicle or home.
2. Make sure that the television antenna provides an adequate (“snow-free”)
signal and that you are using good quality cable between the antenna and
the television.
3. Keep the cables between the battery and the inverter as short as possible,
and twist them together with two to three twists per foot.( this minimizes
radiated interference from the cables.)
4. Move the television as far away from the inverter as possible.
5. Do not operate high power loads with the inverter which the television is on.
9. CHOOSE THE BATTERY
9.1 Battery Requirements
Battery type and battery size strongly affect the performance of the power
inverter. Therefore, you need to identify the type of loads your inverter will be
powering and how much you will be using them between charges. To determine
the minimum battery size that you need to operate appliances, follow these
steps:
1. Determine the wattage of each appliance and/or tool you will need to
simultaneously operate from the inverter. To do this, read the labels on the
requirement to be operated. Usually, power consumption is shown in watts. If
it is shown in amps, multiply by 220-240V to determine the wattage.
2. Estimate the number of hours the equipment will be in use between battery
recharges.
3. Determine the total watt-hours of energy use, the total running time and the
average power consumption power (in watts) by 10 in 12V system.
4.
To calculate the approximate power a 12 volt battery bank has to supply in amps,
you need to know the current, or amps required for powering the continuous AC
load. A easy method is to divide the continuous AC load wattage by 10.
For example, the continuous AC load is 2000 watts, the current (amps) is:
2000/10 or 200amps at 12VDC.
Notes:
some appliances required high surge power to start, then consumer less
power. And some appliances are not operating for long periods of time. For
example, a typical home-use coffee maker draws 500watts during its brew time
of 5minutes, but it maintains the temperature of the pot at about 100watts.
Typical use of a microwave is only a few minutes, sometimes at lower power;
