5. Attach a "Ferrite Data Line Filter" to the television power cord. More than
one filter may be required. These filters are available at most electronic
supply stores.
Note:
Some inexpensive audio systems may produce a slight "buzzing" sound when
operated with the inverter. The only solution to this problem is to use a sound
system with better power supply filtering.
How This Modified Sine Wave Power Inverter Works
There are two stages in which this power inverter changes the 24 volt DC (or
battery) power into 110v AC (household current).
STAGE1: This inverter uses a DC to DC converter to increase the DC input
voltage from the battery to 145 volts DC.
STAGE2: The inverter then converts the high voltage DC into 110v AC
(household current), using advanced MOSFET transistor in a full bridge
configuration. This design provides this PowerBright

inverter with the
capability to start and run difficult reactive loads, while providing excellent
overload capability. The waveform that is generated by this conversion is a
"modified sine wave" as shown in the diagram below.
a pure sine wave. Consequently, most meters will not read the RMS

Best use of Battery Power
Make sure any appliances are energy efficient and turned off after use.
Use Compact Florescent Lamps. Wherever possible, charge with Solar
Panels or Wind Generators. Do not allow lead acid batteries to remain
discharged for long periods of time, they lose capacity (amp hours).
Disposal / Recycling of Inverter / California Proposition 65
Electronic products are known to contain materials that are toxic if improperly
disposed. Contact local authorities for disposal and recycling information.
This inverter is certified to be “lead free”. Transformers in this inverter contain
nickel composites. Nickel is a known neuro-toxin if ingested.
