About the WiFi Configuration
- Why can't I find the WiFi signal on mobile devices?
Normally the WiFi signal can be seen immediately after inverter has powered up. However, the WiFi signal will disappear when the inverter connects to the internet. If settings need to be changed, please connect the router. If you cannot find the WiFi signal or connect to the router, please try to reload the WiFi. - Why can't I connect to the WiFi signal on my phone?
The WiFi module can only connect to one device at a time. If the signal is already connected to another device, you will not be able to connect to the signal. - Why does the WiFi module fail to connect to network after I choose the right router hotspot and enter the right password?
It's possible that there are special characters not supported by module in the hotspot passwords. Please modify the password to consist of only Arabic numerals or uppercase / lowercase letters.
About Battery Operation
- Why does the battery not discharge when the grid is not available but it discharges normally when the grid is available?
On the APP, the off-grid output and backup function should be turned on to force the battery to discharge under off-grid mode. - Why is there no output on the backup side?
For backup supply, “Backup Supply” on the APP must be turned on. In off-grid mode or when the grid power is disconnected, the “Off-Grid Output Switch” function must be turned on as well.
(Note: When turning the “Off-Grid Output Switch” on, do not restart the inverter or battery. Otherwise, the function will be switched off automatically.) - Why does the battery SOC suddenly jump to 95%?
This normally happens when BMS communications fail when using lithium batteries. If the batteries enter float charge mode, the SOC is automatically reset to 95%. - The battery cannot be fully charged to 100%?
The battery will stop charging when the battery voltage reaches the charge voltage set in the APP.
About APP Operation And Monitoring
- Why can't I save settings on the APP?
This could be caused by losing the connection to WiFi . - Why are the data displayed on the homepage different from the param page, like charge/ discharge, PV value, load value, or grid value?
The data refresh frequency is different, so there will be data discrepancies between different pages on the APP as well as between these shown on the portal and APP. - Some columns show NA, like battery SOH, etc. Why does that happen?
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 CT and Power Limit Function
- How to activate the output power limit function?
This function can be activated by following these steps--Make sure the Smart Meter connections and communications are functioning correctly. Then enable the anti-countercurrent function on the APP, and set the maximum allowable countercurrent 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 100W when exporting to the grid. ) - Why is there still power exporting to the grid after I have set the power limit to 0 W?
The export limit could theoretically be 0W but there will be a deviation of around 50–100 W. - Can I use other meter brands to take over from the Smart Meter in the system or to change settings in Smart Meter?
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. - What is the maximum current allowed to pass through the CT ?
The maximum current for the CT is 88A.
Other Questions
- Is there a quick way to make the system work?
For the shortest resolution, please refer to User Manual. - What kind of load can I use to connect to the backup side?
Please refer to User Manual. - 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?
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.
