[Newbie] Sunways hybrid inverter showing 287.5V and 310.5V as overvoltage protection limits (India, 230VAC)
Hi,
looking for some clarity on my 5KW Sunways hybrid + Dyness battery setup here in India.
So my installer messed up the external CT clamp wiring. It's reading my export as house consumption, meaning the inverter has absolutely no idea what my actual load is. I've been dealing with that separately, but today I just said screw it and turned on export to see what happens.
I'm generating 3.2KW from PV and the app shows all of it going out as export. My residential meter confirms around 3KW being exported, so that checks out. But here's where it gets concerning. My meter side voltage climbed to 257V and occasionally spiked to 260V while I was exporting.
We're on a 230VAC single phase grid in India, so I'd expect the inverter to trip or at least throttle export somewhere around 253V (that's 230V +10%, which is the standard upper limit). But when I checked the app, it's showing the overvoltage limit as 280V. That honestly seems insane for a 230V grid.
So I'm wondering, is the app just displaying some other parameter and not the actual protection threshold? Could selecting India in the grid settings apply a lower internal limit that the app just isn't showing correctly? Has anyone with a Sunways unit actually verified what the real trip voltage is under the India profile?
I already have the CT situation to sort out, but honestly the voltage thing is bugging me more right now. Any insight would be really appreciated!
I am adding the app screenshots
