i was using my cheap, noisy and unefficient chinese AIO [a voltronic clone VM 1000watt] for a mini fridge(40w nominal wattage n 1,2Kwh per day consumption) n charge my e-moped (72v battery charger user 240watts)
upgraded to Pheonix 12 500 Schuko (surge is 900VA) n when i open inverter even red led doesnt light. It just goes offline.

Is there any simple fix (like a supercapacitor)? i dont want to use 12 800 or 1200 cos cabling gets too thick.

(i checked all cables, fuses n breakers work with cheap inverter)

This is how compressor fridges work. Even if the running power might be 40-70W you need at least 1000W to start the induction motor. Even a 1000W inverter connected to a very good battery might fail to start.

My tests have shown 1200W peak power for a second or 2. Also the battery must be able to supply around 100A?

Charged another 100Ah lfp

Now Phoenix can start mini fridge. W 2 100Ah blue carbon LFP s

+1 for phoenix. That old fridge need a lot amps to start.
