Hi, there is many questions about the working of the REVO II series from Sorotec ( same model as EASUN IGRID VE II ).
After many questions to the Engineers, i finally got mine to work.
General Function - This inverter doesn´t like to work with a PV array with Open Circuit Voltage over 300volts. Be sure you set and configure your array to be under 300volts.
CT Limiting Function
- PV Open Circuit Voltage below 300volts
- having a CT sensor 100A/0,333volts
- The CT sensor must be in the correct direction, load displays ( - ) Watts, feed in displays ( + ) Watts. if wrong, just change the direction of the sensor.
- Working Mode - AC+PV with CT sensor Selected
- Ongrid Mode - Set to OFF
You the can calibrate you CT sensor in the other menu to match you load correctly.
Battery
If you are working with LIFEPO4 cells, in the battery menu , select USER and define Bulk and Float
If you have batteries, and you select AC+PV the battery will act as a UPS, only discharges if the AC power goes off. From my findings the PV only powers loads and batter, it will feed the grid with the remaining power.
I tryed pushing more loads and it got it from the grid, not from the battery, so i assume it is backup only mode.
I also got a software for battery voltage and amps calibration but i haven't tested it yet.
Monitoring
For monitoring, i use Jblance code in a raspberry pi. I got the protocol from this inverter and JBlance manage to put it in the software and it is working fine.
you can use Wifi Logger and the app works ok, but i as looking for more detail, that is what i get from graphana in home assistant.
Any help i can give about this inverter, just ask.
