This inverter is requires 12 volts input power. The inverter can be connected to multiple batteries as long as the input power to the inverter is 12 volts.

answer 2
Yes depending on how they are hooked up, if they are hooked up so you still have 12 volts positive to positive cable then Yes. If the batteries are hooked up positive to negative post then it becomes 24 volts and the invertor will not work.

Question

Modified sine wave vs. Pure sine wave?

Reviewing the different modified sine wave inverter vs. the pure sine wave inverters they all have specs. that say suitable for small appliances, tv's, phones, laptops etc. Why is the " pure sine wave " inverter better and higher priced?

The current produced by modified sine wave inverters like this one is not considered to be as "clean" as the current from a pure sine wave inverter. While this modified sine wave inverter has low harmonic distortion and is suitable to operate most electrical devices, using a pure sine wave or true sine wave inverter is recommended for running especially sensitive products like laptops, TV's, etc. Pure sine wave inverters are more technologically advanced and therefore more expensive.

As the expert said: Pure sine wave inverters cost more because they are much more sophisticated than the Modified ones.

If your device has micro-processor technology, the modified inverter can and eventually will destroy your devices electronics.

Same would hold true for a common "Worksite" Generator vs an Inverter Generator.

Best to use something with less than "3" Total Harmonic Distortion. Generally your household wall current is 0-3 THD.

Modified Sine waves can be considerably above that.
I suggest that you Google a comparison.

This should get the job done with capacity to spare. I have been able to power quite a lot with it, but make sure you have a decent amount of AmpHour capacity if you want to run it for extended periods. 200watts @120v = 1.67amps. So it would draw around 16.7 amps from a 12v battery...

NPower Expert
This unit will supply 400 watts of power. The rating of your sound system is 400 watts, however sound systems are typically rated by the output wattage and not the input wattage. Due to electrical inefficiency, the input wattage is typically higher than the output wattage of a sound system. To determine the wattage that is required to run your sound system you will need to look for a name plate on the receiver or amplifier that lists the amperage requirement and multiply that number by the number of volts that it operates on (typically 120 volts), this will give you the wattage requirement of the unit.

amps x volts = watts.

Once you know the wattage requirement of the unit that you are running it is a good idea to find an inverter that will supply 20% more watts than you need. This will keep lower internal temperatures ensuring a reasonable service life of the inverter.
