About PV Master Operation And Monitoring
Q: Why can't I save settings on the PV Master App?
A: This could be caused by losing the connection to Solar-Wi-Fi *.
1. Make sure you have already connected to Solar-Wi-Fi* (make sure that no other devices are
connected) or to the router (if Solar-Wi-Fi* is connected to the router). The APP homepage shows
the connections.
2. Make sure you restart the inverter 10 mins after you have changed any settings because the
inverter will save the settings every 10 mins while operating in normal mode. We recommend
that parameter settings be changed when the inverter is in wait mode.
Q: Why are the data displayed on the homepage dierent from the param page, like charge/
discharge, PV value, load value, or grid value?
A: The data refresh frequency is dierent, so there will be data discrepancies between dierent
pages on the APP as well as between these shown on the portal and APP.
Q: Some columns show NA, like battery SOH, etc. Why does that happen?
A: NA means that the App has not received data from the inverter or server because of
communication problems, such as battery communications and the communications between
inverter and the App.
About the Smart Meter And Power Limit Function
Q: How to activate the output power limit function?
A: For the inverter system, this function can be activated by following these steps:
1. Make sure the Smart Meter connections and communications are functioning correctly.
2. Turn on the export power limit function and set the maximum output power to the grid on the
APP.
Note: Even if the output power limit is set to 0W, there might still be a deviation of a maximum
of 100 W when exporting to the grid.
Q: Can I use other meter brands to take over from the Smart Meter in the system or to change
settings in Smart Meter?
A: No, because the communication protocol is integrated into the inverter and Smart Meter,
other meter brands cannot communicate. Also, any change to the manual settings could cause a
meter communication failure.
Q: What is the maximum current allowed to pass through the CT on the Smart Meter?
A: The maximum current for the CT is 120A.
Other Questions
Q: What kind of load can I use to connect to the backup side?
A: Please refer to On-Grid&Back-Up Connection section.
Q: Will the warranty of the inverter still be valid if, for some special conditions, we cannot follow
100% of the User Manual instructions for installation or operation?
A: Normally we still provide technical support for problems caused by not following the
instructions in the User Manual. However we cannot guarantee any replacements or returns.
So, if there are any special conditions for which you cannot follow the instructions 100%, please
contact the after-sales department for suggestions.
