I bought a Tassimo Pod Coffee machine by Boss and it works fine at home, but fails using my inverter. Is my inverter pure sine wave? If yes should it operate this 1400W coffee maker?
Does the inverter switch off due to overload or can your batteries not cope and it switches off due to the low battery voltage?
There are hairdryers, coffee machines and pad machines that simply wonāt run on an inverter with 3000W.
This is often due to the āinternalā electronics used for water heating.
It is no longer a pure heating coil but a very ādirtyā mixed load of ohmic, capacitive and inductive load. The inverters donāt like that at all.
I have a 300amp Fogstar battery and nothing cuts out. The cofee machine starts up ok, but then fails to boil the water, I think. My battery was 100% when I last tried. It is possibly a technical issue with the Bosch.
Since it works on a normal connection, I would say that it is NOT due to the Bosch.
Check all the connecting cables from the battery to the inverter.
You should be getting over 100A to the inverter. Perhaps the contact resistance in the battery cable is too high?
Can you measure the voltage at the inverter connections when you operate the Bosch?
Have you ever operated loads as large as the Bosch on the inverter?
Maybe there are some switch-off conditions in the Phoenix !
If is is 1400W with a power factor of 0.6 then that is an evil load for a 3kVa.
Total shot in the dark here, but have a look at the info plate on it.
Your DC cabling will have to be on point for it to work well on a 12v system
Its a heater, so the power factor should be 1
Pulsing or cutting the sine wave is an ugly load for an inverter.
@DadaDee Use VictronConnect to connect to the inverter and it will tell you why itās shutting down.

Ideally yes. But {almost} all the coffee makers now have triac based for power control and they chop sine waves.
Best way to know is see the info plate on the device.
āALLā Coffee makers ?
I have several philips and a wmf machine, no triacs used. Why should they, money for nothing, heaters work fine with on/off or pwm regulators.

Ok statement too sweeping.

Pwms can also cause weird overloads they still send noise into ether. Depends on the device.
PS the pwm circuit is also works by chopping.
No, a good transient free pwm switches in the zerocrossing of voltage/current.
Maybe we have a different market hereā¦ a good (not cost cutting) pwm power supply on a coffee maker? Not arguing that there arenāt good ones. Just pointing out that it and a power factor issue was a possibility.
The tassimo coffee maker comes from the same market. The philips senseo sells from 30ā¬ upwards, the WMF upward of 200, the Tassimo somewhere in between.
The bosch temperature regulator is a simple mechanical thermostat.
