Hi,
I have a Growatt SPF-DVM 6000T in a very off-grid location (rural northern Colombia) with 4050W of panel input. We had a washing machine which completely failed a few months ago and have recently bought a replacement washing machine (Haceb 9002542) which claims to have a nominal motor consumption of 700W. It is used quite regularly and causes the growatt to trip almost every time it is used (daily), seemingly when it enters into its spin cycle. The inverter claims to have a surge rating of 18KW at 20ms but doesn't seem to comply with that, it trips when certain 1200W power tools are started.
Does anybody have experience with sizing up a capacitor bank at an outlet which supplies surge loads? I'm interested to see if a capacitor bank will absorb the surge and cause the inverter to stop tripping.
Alternatively: This model of growatt has a split phase output and I am currently powering the washing machine off a single 110V phase, which only allows it 3kW of total power (so I assume only 9kW of surge?). I have another hope to fix it by buying a 220V to 110V step down transformer and wiring it across the two lines for 220V and plugging the washing machine into that, allowing it 6kW of power and a higher surge protection. Is there any reason this shouldn't work?
Attached is the consumption sticker and product number for the washing machine.
