Advice on buying generator please

Hi

I am looking at purchasing and running a drinks cooling machine to run on no mains electric what so ever!

The company that sells the machine have advised the following

Frequency: 50Hz Rated current: 5.5A Rated input: 800W

This machine is a liquid to liquid based (water and anti freeze bath) heat exchange and only runs when liquid is passing though it. And will only operate when I open the tap and fill a glass up from it so it will not be running most of the time

The two option I am considering is buying a generator inverter and battery and charging the battery up as required. Or just running the generator when it is in operation. So what do you think?

Thanks

Im not quite so sure what you are asking hear but......

As I said I am no expert in batteries and brands of but I reckon there will be a difference between the battery life and guarantees/specifications of performance when it is used primarily for a few seconds to crank an engine and when used regularly for prolonged discharge to a deeper depth of discharge. Hence the rather odd phrase 'leisure battery'. I know nothing about the Platinum make.

To do the analysis of battery and generator charging I need to know how long the battery alone must provide power and remain above 50% discharge. In my clients case from shut up shop 7pm Saturday evening to opening up 7am Monday morning.

Leisure battery or better term deep cycle batteries are not what you find on a car! car batteries use a different type. Commonly refered to as CCA (cold cranking amps). A deep cycle battery will simplely not start an engine and a CCA battery will not last as long as deep cycle.

Anyone in the motor trade will know all about Platinum batteries. They are one of the best!

But again I am not quite so sure what you are asking hear. Because if I had the 200AH battery in question that I would discharge it to 50%. Then what size generator would you recomend if I wanted to charge it up for say 30 minuts?
Thanks
