Generator vs Leisure Battery

Hi David and everyone else

I've written in previously and am very grateful for the response but I need more help regarding how to power everything in my little catering trailer. It has been suggested to me a few times that powering everything with gas is the best way to go but I've also seen a few things about people using one or more leisure batteries.

I have a standard fridge (no freezer), 2x10litre soup kettles (that would be used in Autumn/Winter/cold weather days), lights, a non commercial panini grill (so big enough for one or two sandwiches at a time) and most likely a coffee machine (size and type as yet unknown). The trailer has plug sockets dotted around and 2 water containers under the sink. The measurements of the trailer itself are 2300x1650x2300mm.

The only time I actually need everything to be 'on' is during working hours (3 or so a day) and the rest of the time food is made and kept in my house.

I really need answers explained to me as though I know absolutely nothing, please don't even assume I know the most obvious things, I cannot stress this enough! I'm just getting more confused the more I talk to people!


Thank you very much in advance for any help and advice, I really do love this mobile catering community!

Help! How do you use an inverter to power lights?
by: Lady

Hi everyone,
please can someone explain to me step by step how to use the inverter to power my lights? Do I need an electrician do carry some work on my trailer? If so, how much it should cost? Please, if you have any tutorials kindly share them with me because I know nothing about this stuff! Thanks to all of you and have a great day!

Catering Generator
by: Perry

The majority of caterers use lpg gas.
A 19kg bottle will give you a 19kw supply.

By comparison leisure batteries are 75-100amp/hour at 12v, a cigarette lighter socket can give max 120 watts (0.012kw) and run that for 7.5-10hrs

The run 230v (mains) you need an inverter, cheap ones will do 300watts, enough for lights, 2000 watts (2kw) start getting expensive.

Kettles draw an average of 3000watts (3kw), 2 x 100 amp hour batteries would run a kettle for max of 48 minutes.

12v solar, batteries and led lights are a good cheap sustainable solution but not for running catering equipment.
