Electrical question

[drewdt3]

I would be grateful if someone could answer a couple of questions. I'm not great with leccy and was wondering if I should get a smaller inverte.r I have a 350w unit and only use it with the TV on the odd occasion that we are away when F1 is on, well frequent occasion actually. The TV is rated at less than 30 watts. Does a smaller one mean more efficient for that application?

The second pondering I have had is would 2 6v traction batteries each being 225ah joined to create a 12v supply be 450ah or is there some equation that should be applied to give a 12v ah figure. This is probably a stupid question but as I say I'm not great with leccy.

Cheers

A 150 watt inverter is more than big enough. We use one when we use a 30 watt TV and 240 volt Sky Box (wattage unknown) together. Anything smaller, like 80 watt might cut out with long use.

I have a small 80 watt inverter which is only suitable for very small items like mobile phones, battery powered electric razor, etc.

Q 1, won't make much of a difference

Q 2, 2 x 6v 225Ah in series = 12v 225Ah, in parallel = 6v 450Ah.
