Question about Black & Decker 1000w Power Inverter
Posted by Anonymous on
Your numbers don't add up. Where are you 'seeing' 200volts. Your lap top power supply transformer uses 120 volts AC. Are you plugged into a 240 volt outlet or something? Your inverter should be 12 or 24 volts DC input; to AC power usually 120 volts AC. Check out you output plug, should read 110 - 120 volts AC

First, you should be aware that the exact inverter is available for under 40 dollars all over the US. Your model is sold under several names - check out http://search.harborfreight.com/cpisearch/web/search.do?keyword=inverter .
I suspect that your INPUT power level is not adequate for the inverter to put out the 200W that the 150W charger needs. If you have low current and low voltage - then the inverter can only put out a proportionally smaller AC wattage level. You may also have a faulty voltage sensor....at the input. Once the inverter sees a low level (even momentarily), it alarms and shuts down the output until the unit is reset (turned off/back on)

The problem of your inverter is from
your battery .your laptop and dvd
player requires little current to
operate.But you tv requires more power
to run, if your battery is low you it will
not last for 3 minutes. If your battery
has a low current rating, it will also be a
cause, for example, if it is below
100ampere hour. Lastly if your battery
is bad i.e. if it reads below the
stipulated dc voltage Require by your
inverter to operate.

I looked at the power requirements of this projector, 280W, but that assumes a nice sine wave. Your inverted is supposed to put out 400W, but it's a modified sine wave. Under ideal conditions (including a good battery) this might be just enough. Connecting directly to the battery will help a little, because of the limited ability to get current to and through the cigarette lighter. Using a 100 foot extension cord will diminish the voltage a bit (less so if it's a heavy gage wire). I would try connecting the inverter directly to the battery, run the engine and skip the extension cord. If that works, turn off the engine. If that works, try the extension cord. If it won't work with the engine running, connected directly and no cord - there are two possibilities: (1) the projector just won't run on a modified sine wave, (2) you need a bigger inverter. --- regarding (1) I have seen lots of people having trouble with various devices. You might want to ask Epson support. --- Good luck!

There are two possibilites: the first is the over 400W power draw, the other is how you have the inverter connected. Do you have the inverter connected directly to the battery terminals (the clips) not the outlet plug (cigaretter lighter)? This is needed for any load over 80W and under 400W. (the inverter can handle a load demand over the 400W limit but only for short periods (800W).)
What is the load that your PC pulls (Is it a laptop or a desktop)? The laptop in my home has either a 65W or a 90W load (depending on the battery and the AC adapter we are using). Desktops take much more power (usually).
I hope this helps.
