Hi Folks,
My van is used for going mo’bike racing and there usually aren’t many/any hookups in the paddock so the van is generally plugged into a non-inverter3.5Kw generator. When it’s running the 240v LED spotlights flicker so I know I need to do something with a power regulator to get rid of that issue but, the bigger issue is coffee !! When plugged up to the gennie, my coffee machine takes an age to work and then produces small squits of coffee at a time so it takes ages to get a brew. I’ve tried several machimes all rated around 14-1600 watts and only one of them worked…Anyway
I have 2 x 110ah leisure batteries on a Victron Smart charger and a 3000W Edecoa inverter do I thought I’d be smart and run the coffee machine off that. When I tried it, the coffee machine lit up and appeared to be heating up but…Stayed looking like it was heating up…No Coffee 
There is obviuously output from the inverter and stupid me though it would run the coffee machine easily…Am I dumb or am I missing something ??
TIA for any advice/thoughts
PS - Coffee is a fundamental and critical racing component…Right up there with petrol, tyres and leathers !!
You don’t have enough AH to run a 3K inverter. At min add another battery
Errrr…220AH in the batteries / 60% = Should beore than enough !! - Max draw would be around 10amps - How do you figure it’s short ??
Have you tested your generator output voltage? You said your lights flicker.
Coffee maker might be sensitive to “noisy” unstable power output.
Do tools and other appliances work normally off that generator?
Also hope you got pure sign wave inverter, because coffee makers might be sensitive to that.
I heard they can be fussy requiring very stable power input or be frequency sensitive and if you found one that works I’d just use that.
PS: in all the years I drank coffee in the past out in the woods I never needed power to make it, basic propane backpacking stove and cowboy or turkish coffee pot make great coffee…
So you are having trouble running off batteries + inverter, too? Again have you tested the inverter ouput voltage and batteries voltage. To test more you need more tools, so that coffee would be getting much more expensive.
Also, have you tried grounding the generator, just another idea…
Apparently, some machines use Silicon Controlled Resistors which mess with frequency, ffs !! Though why they don’t work off the inverter is a mystery (To Me, anyway) - Everything else if fine, just the newer coffee machines. Guess the older one doesn’t use an SCR…
