Hey guys!
I have the exciting but challenging task of working out a mobile power supply for a 2 group Synesso
I'm wondering if there are any battery or coffee cart experts in here that could help me out. (Powerman where are you? :-))
One thing to note is one of the steam elements will be disengaged bringing the total draw of the machine to around 3800watts.
The breakdown is:
Steam element 2000 watts
Each group head 700 watts
Water pump 400 watts
Firstly, I've worked out that a petrol inverter like the Honda EU65is will likely do the trick. It can take continuous output of 5500 watts and peak 6500 watts.
Only thing is they make a little noise, and while it's probably tolerable, I'd like to explore any other options before taking the plunge.
So I'm wondering if anyone has experience and could recommend an inverter system powered by batteries?
I've seen a few inverters that look like they'd do the trick, but am quite unsure about the batteries.
My other question is, is there a way to work out how many amps the machine would draw in an hour, or for a certain number of coffees made?
For example, for 100 shots does the machine draw 700watts for the total of around 50minutes (at 30 seconds a shot)
And for the steam is it just when the steam is engaged that it draws the 2000watts (so for 100 coffees, 2000watts for 17minutes at around 10 seconds each milk heated)
I assume there is probably a fair amount of power draw in the warmup as well, and maybe a little in between shots and steaming. But is this an ok way of working it out, or is it way off?
Any tips would be great!
Finally, I'm wondering if anyone knows everything needed in a battery/inverter setup?
My guess was the inverter, enough batteries to supply the power, and a battery charger. Is this it or is there more?
I'm slowing bettering to understand I think, but I clearly need an expert to show me the way!
Any tips, advice or recommendations would be greatly appreciated!
Thanks so much,
Geoff
