Hello again. I have a 1000w pure sine wave in invertor with 2000 w surge. Control. I tried my ice making machine and it tripped invertor after a few mins. Any help most appreciated.
Well, you had me stumped for a moment on the Icemaker, didn't have a clue what the power demand would be, but a quick Google threw up a few domestic types that seem to draw no more than 120W, so that then leaves both of us none the wiser, as a 1kW (with 2kW surge) should be well within it's comfort zone!
Maybe more info on both Icemaker (make, model, power rating etc.) and the make and model of Inverter may help us help you.
Tongue in cheek question, do you prefer your camping cocktails shaken or stirred!
Thanks for the reply. Yeah not sure what's going on with it. It seems to handle the 700w microwave OK. And the ambiano ice maker is as you said 120w it seems to be when compressor kicks in it trips. The ice machine does vent a lot of heat so not sure what the surge could be when compressor starts... Definitely shaken. 🙂
It will run for around 10 mins then will cut out. It's a new machine. No visable condensation at drips. Thinking maybe charge going to the leisure batteries dropping during use. I have 2 x 110amp batteries being topped up from 100w solar panel on roof
Again all new
The start up surge of devices can be huge, it varies from device to device, and is often the downfall of inverters (and generators!). I've tried fridges that are a fraction of the capacity of the inverter, and 'should' run, but the start surge just stops it dead as an overload!
Could be that rather than inverter tripping because of load demand, it's tripping because 12v supply voltage drops below set safe (battery discharge protection) threshold on a surge demand. That would explain why it runs for 10 mins or so, long enough to drag the battery voltage down a little, then next surge pushes just too far and it trips out trying to save the battery from excessive discharge.
Inverters are pretty inefficient devices, and put their own demands on the supply battery, so the load on supply is up to 20% higher than the powered device alone might suggest!

It runs for about 10 minutes so there should be no issue with start up surge?
