I was happy for the branch cutter, trying it on 2kW inverter. Motor is 1400W but does not work. Coffee machine has 1200W and 800W plates and both heating fine. I would need 3kW for the motor perhaps, but maybe better to downgrade the motor. The battery wouldnt hold too long with such high power load. I need to run it on 80Ah battery for around 20 minutes.
