What size generator would you need to run a 300 watt pa sound system for a few hours?
A 300 watt audio system means it has a peak power of 300 watts but the average power might be only a fraction of that, perhaps 5-10 watts. So it might run off a car battery, with an inverter to supply the correct voltage if needed. <<>> A 300 watt public address sound system will operate very nicely from as small as a 500 watt AC generator. A 1000 watt generator will give you more capacity if there are other devices that need powering.
What can you power off a 1200 watt generator?
Anything up to 1200watts
Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
What percentage is a 100 watt light bulb brighter than a 60 watt light bulb?
Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.
How many lumens does a 42 watt CFL give off?
a 42 watt cfl give off 2800 lumens
How many 400 watt metal halide lamps will operate off a 1000 watt ballast?
It will power two 400 watt lamps.

Can 5 cup coffee maker work on an 300 watt inverter?
It can, but you cannot have anything else turned on at the same time, or it will kick it off. You will really need a larger inverter, and preferably a high voltage battery or battery bank. Marine batteries work the best, and last longer. A 300 watt inverter, will not carry the load for very many things.
Are a switch and inverter the same?
No. A switch can turn the electricity on/off, but an inverter can provide electricity(for a limited amount of time) if their is a power failure.

Can you run a 8000 watt inverter off a battery and charge the battery at the same time?
it depends exactly what system you are running. im guessing you mean of a car battery and small charger. no. you will inevitably kill the battery, then the charger will overheat, short, and smoke the inverter. however if you had a large bank of batterys and suitably large charge system then there should be no problem. e.g.a solar system charges battery through the day while large volumes of power are drawn through an inverter to power appliances. if your inverter has a low power cut off and your charger has an overheat protection system then you could most likely try it. many good inverters (12 - 240v or 12 - 150v) have low voltage protection which switch off at 12.1v saving your battery also. remember if you drain your battery, recharge it asap.
What is the Difference between off-line and online UPS?
The offline UPS is in standby mode. The charger is maintaining the battery, but the inverter stage is not running. Power goes from input to output, bypassing the inverter. In this configuration, the charger and inverter design is less, as the charger is usually in trickle mode and the inverter does not need to run continuously. On power fail, the inverter starts up and takes the load. There is a glitch in output, a few line cycles, but most loads can handle this. The online UPS runs all the time. The charger now runs the inverter, as well as maintaining charge on the battery. The inverter supplies the load. Power goes from input to charger to inverter to output. In this configuration, the charger and inverter design is more, as they need to run continuously. On power fail, there is no glitch, because the inverter is already running and supplying the load. Usually, there is synchronization between the inverter and the line, so that failure of the inverter can initiate fall-back to the line without glitch.
WHAT IS THE Difference between an inverter and UPS?
In UPS ,the main power comes to the UPS and is used to charge a battery inside. The output from the battery is fed into a sine wave inverter which converts DC into AC and feeds to the computer in case of a power failure. In such a scenario, the battery is stopped from charging and instantly starts to supply power to the computer. In Inverter ,AC is converted into DC and then is used to charge the battery. When the power supply goes off, the relay triggers the switch from mains to inverter. It is the use of a sensor and a relay that is the main difference between a UPS and an inverter, otherwise the two are same. And the use of relay and sensor cause the time delay in power supply from an inverter.
I have a 5kVA inverter and the inverter will be off always. when the main source fails the inverter should feed supply to laod. in this case my inverter is overloaded due to initial surge. what to do?
To prevent you backup Inverter from sudden overloading. You should manually control your Inverter. When power fails. Shut down all loads. Turn on your Inverter with a with no loads on the AC line. The slowly begin to turn on loads to your backup Inverter. Start with just the lighting systems and then work you way to higher current loads such as Air Conditioning Units. Another way to solve your problem is add maybe 5 additional Units in parallel. You need to calculate all the power loads in your house is using making sure your inverter can handle the complete load. Why the Inverter fails is due to high inductive loads. The Inductive loads appear as a short circuit to you Inverter. The only way around that problem is to limit the number of inductive loads the your Inverter is supplying power to.
Do you need a 1000W plus inverter to run a 1000W PA at low volume off a battery?
At low volume you could get away with a much lower watt inverter, however, if you intend to use more it would be better to have the full range at your disposal. Peak output power for one of those is typically around 2400w, but be aware that it will generate some heat in use so locate it in a good area with airflow.
How do you run 110 power off a car engine?
Simply purchase a power inverter. These are available at any electronics outlet, ie best buy, circuit city, walmart...
