This is to address a problem which is common in every Solax 10.0Kw X3 Hybrid G4 inverter.
It has been tested that during EPS Mode when following type of load is applied
Load which is equipped with specific capacitors (not each capacitive load).
For example
a. Some of mobile chargers.
b. Some of laptop chargers
c. Some of LED monitors
d. Some of LED Tube lights
e. Some of water pumps
Then
Following reaction occurs from inverter:
Inverter turns off its output for a while (around 0.25Sec)
Inverter turns off PV incoming power
Inverter turns on its output again automatically
Inverter put all load on batteries when inverter turns on back after a while.
Then again slowly get power from PV.
No alarm is logged in alarm history.
Please note following points:
There is a video in attachments. Which describes the reaction of inverter.
This test has been performed on 2 same model inverters
This test has been also performed by removing all loads from Inverter and by connection isolated single board.
All ground points are connected.
Each Installation step is according to Solax provided installation manual.
This phenomenon is not related to loose wire or loose connection, instead this is related to just turning on appliances.
It is observed that This phenomenon does not occur when grid is connected.
One more thing that this phenomenon does not occur each time when we turn ON above type appliances. This phenomenon occurs sometimes on 1st turn and sometimes on 3rd or 4th turn.
What I think is that it's output LC filter is not design perfectly as it should.
