24v to 240v inverter

[Al-Di]

is this type of inverter any better than a 12/240,

have 3 110 ah batteries so connection is not a problem,

also 280w solar system being fitted,

No, no benefit at all. A 12v - 230v inverter would be by far the most sensible option for you.

If you connect two of your batteries in series to provide 24v your 12v habitation system will only have one to use.

Also two 110ah batteries in series will give you 24v but only 110ah which at a 50% discharge is 55ah which equates to about 20 minutes at 2000W using the inverter.

And finally there will probably be an issue with getting the solar panels to charge both systems unless you have more than one panel and a regulator for each voltage which will cancel the benefit of that much solar even assuming the solar panels will work on a 24v system at all.

The same people also do a pure sinewave (allegedly according to their listing and spec info) 12v inverter for the same money.

Looks identical but 12v / 1000watt cont / 2000watt peak.

40 minutes actually as it would be running off 24 volts so half the amps.

I would not try to run a 2kw load for that long though, a few minutes for the usual microwave hair dryer and coffee machine and the solar panel will put it all back in a few hours.

If you had 24V already, as we do on the Mercedes, then it might be worth looking at.

We have gone for a 24V winch instead of the 12V unit on the trailer, simplifies the heavy cabling and the actual cables are lighter as the current is half.

Otherwise stick with 12V.
