Currently have a well setup 14kva Quattro running ESS with 51kwh of batterries in a rural location. It’s running node red charging at night on low tarriffs etc and getting IR forecasts.
We do get grid drops however I’m finding the G99 parameters a bit too flexible as it allows 184v for 2.5sec before LOM and switches to Inverting. This flashes the lights as they are LED and I still get a nuisance RCBO trip (Earths all sorted just start up leakage we think)
How can I get it to start inverting and see a LOM situation at a more conservative say 210v and 0.5sec so I don’t experience this. Our grid voltages are high at normally 247v I can’t get it below 233 even drawing 25kva…
I either want to amend the G99 parameters or can I use Node red to switch?
Everything else is fine in G99 I just don’t want to allow brownouts.
Any thoughts, thanks
