Hi, guys,
I'm a new solar guy, just installed 4Kw solar PV ( 9*455W panels ) and a REVO II VE 5.5KW inverter. Did it all alone and everything is working. About the REVO II I'm a little disappointed because some functions don't work properly and others the software lies to me.
I'm grid connected and i don't want to inject power to the grid ( also I'm not allowed to because this inverter doesn't have the necessary certification to be feed power to Portuguese grid.)
Fact one - When you don't select on-grid, with CT function off, the screen shows you are not injecting power, but that is a big lie. If you are producing 2000W on the PV and you are consuming 200W ate home, the excess power is going to the grid. It shows zero feed-in but i have measured and it is going to the grid. So that is a huge lie from the brand and from the inverter info displayed. If you select CT, even if you don't have one, it will show you that power going to the grid.
Question one - I have the CT sensor, a 100A/0,333V split core CT and i select the CT on the inverter, deselect on grid mode as said by the Sorotec, but I'm still feeding allot of power to the grid. It seams that bellow the 1000W PV i see the solar panels shutting down and slowly going back up, for some time, like it was trying to limit, but it never stays fixed to the amount I'm consuming at home. After 1000W it doesn't do anything, just sends all the excess to the grid.
Does anyone here have the same inverter with the CT function limiting properly?
I have seen other inverters and when they are limiting and just stay in line with the amount of power produced, 10 to 15W difference but they keep up and never inject power to the grid. This one is not working like that and i don't know if this is normal for this inverter or not.
My settings are:
Mode - PV+AC with CT sensor selected
Ongrid ( not selected )
PV - 4000W
CT Funtion - fine tuned to match power consumptions and injection ( i think it is at 950 )
The screen show CT in + power when injecting and negative when it is consuming.
I appreciate you help guys. Im going mad with this.
