Power inverter at art shows

Well, make up your mind. Was it a someone, or was it multiple ones.

Obviously. You already said you saw one in use.

An RV battery would fit the ticket. Check at *-Mart. Automotive batteries are designed for the short-term large current draw required by the engine's starter. RV batteries are designed for lower current draw for longer periods of time. Let's say you get one that's rated at 50 amp hours (pulling a number out of thin air). That means you can draw 1 amp (~10 watts AC) for 50 hours or 10 amps (~105 watts AC) for 5 hours.

Where did you read that?

If the inverter needed to be 10 feet from the battery, why would they only put a 2½' cord on it?

Thank you very much for the information and the reply. I truly appreciate it.

I apologize that my post as written annoyed you.

wow.... when did potters start giving a ____? I guess I'm still a 60's hippie...

I suspect the recommendation was that the inverter should be 10 feet

*or less* from the battery, as longer leads will mean higher resistance and more voltage drop under heavy loads. If you truly need longer leads, you could use heavier-gage (lower number) wire to give lower resistance. You'd have to determine what gage the inverter maker said was OK at 10 feet and not exceed that equivalent resistance. Write back with the specified gage for 10 feet, and the length you really need, if you want help selecting a heavier gage.
