| [No]Should I design an inverter? |

| Seekonk:
Check out the 8010 boards on ebay for about $7. A complete sine wave driver board, just add FETS for H bridge or transformer. Just about plug and play. See http://www.fieldlines.com/index.php/topic,148953.0.html for an example of use. There are several threads there related to this. |

If you can build a 500W 96%+ efficiency inverter then go for it. Vampire current draw, and efficiency do seem to be common problems with store bought ones. Hence you either reduce the life of the battery (risk of overdischarge), or just get less runtime. |

A good part of the idle current is due to the output filter. (Same effect happens in some audio amplifiers, often to an even greater extent.) That can be reduced with a lower loss inductor (will increase cost and size), but why when the simple way out is to just output DC if you're running electronics? For motors, it can make more sense to run them off PoL inverters (VFDs) that can vary the frequency a much wider range than a general purpose inverter can. |

Does China have Home Depots? (your flag says China) Would love to see some pics of one. I wonder if they look like our Ikea. |
| NiHaoMike:
Try changing the polarity of the input? A few PSUs need the DC polarity one way for them to start. Transformer isolation doesn't work very well at the extreme duty cycles often found in inverter applications. |
