A:For EH series inverter, it could connect Lithium batteries which have compatibility with EH
series inverter. With nominal voltage from 85V to 450V.
Compatible lithium batteries can see on battery list in PV MASTER APP
A: This could be caused by losing connection to Solar-WiFi.
1.Make sure you connected Solar-WiFi (make sure no other devices connected) or router (if connected
Solar-WiFi to router) and on APP home page shows connection well.
2.Make sure EH under waiting mode (on APP) before you change any sttings on PV Master APP -
disconnect grid/load/battery, only leave PV connected and then restart EH till see work mode as "wait"
on APP.

Other Questions
About PV Meter Operation and Monitoring
Q: Why cannot connect Solar-Wifi signal on my phone?
Q: On the App, why the data on the homepage and Param page is diferent, like charge/discharge,
PV value, load value or grid value?
Q: On App, some columns show NA, like battery SOH, etc. why is that?
Q: How to Act Output Power Limit function?
Q: Why there is still power exporting to grid after I set power limit as 0W?
Q: What is the max current allowed going through CT on Meter?
Q: Is there a quick way to make the system work?
Q: What kind of load can I connect on Back-Up side?
Q: Whether the warranty of the inverter still valid if the installation or operation does not follow
the user manual instructions, for some special conditions when we cannot 100% follow them?
Q: Can I use other brand Meter to take over Meter in EH system or change some settings on
Meter?
Q: Why there is no output on Back-Up side?
Q: On Portal, why battery SOC has a sudden jump up to 95%?
Q: Why battery cannot be fully charged to 100%
Q: Why battery switch always trip when starts it up (Lithium battery)?
Q: Which battery should I use for EH?
Q: Why Cannot save settings on PV Master App?
Q: Why battery does not discharge when grid is not available, while it discharge normally when
grid is available?
A: It is the character of the Wi-Fi module that it can connect to only one device at a time. If the signal is
connected to another device at the time for some reason, then you cannot connect to the signal.
A: As the data on APP is from inverter and on home page and Param page, the data refresh frequency
is diferent, so there will be a data inconformity between diferent pages on APP as well as between
that on portall and APP.
A: NA means App does not receive data from inverter or server, normally it is because communication
problem, such as battery communication, and communication between inverter and the APP:
A: For EH system, the function could be realized by:
1. Make sure Meter connection and communication well;
2. Turn on Export Power Limit function and Set the max output power to grid on APP;
A: Export limit could theoretically to minimum 0W, but there will have a deviation of around 50- 100W
for EH system.
A: The max current forCT is 120A
A: Cannot, because there the communication protocol is inset between inverter and Meter,
other brand Meter cannot communicate. Also any manual setting change could cause Meter
communication failure.
A: The shortest way, please refer to EH QUICK INSTALLATION INSTRUCTIONS and PV MASTER
APP INSTRUCTION.
A: Please refer to user manual on page 12
A: Normally if any problem caused by disobey the instructions on user manual, we can provide
technical support to help to solve the problem, but cannot guarantee a replacement or returns.
So if there is any special condition when you cannot 100% follow the instructions, please contact
GoodWe for suggestions.
A: On APP Off-Grid Output and backup function should be turned on to make battery discharge
under off-grid mode.
A: For Back-Up supply, the“Back-Up Supply" on PV Master App must be turned on. Under off grid
mode or grid power is disconnected, "Off-Grid Output Switch" function must be turmed on as well.
A: This normally happens on when BMS communication fail on lithium battery. If battery enter
float charge, SOC will be reset to 95% compulsively.
A: The switch of lithium battery normally trips for following reasons:
1.BMS communication fails.
2.Battery SOC is too low, battery trips to protect iself.
3.An electrical short-cut happened on battery connection side. Or other reasons please contact
GoodWe for details.
A:Battery will stop charge when battery voltage reaches charge voltage set on PV Master APP
Note: As turn“Off-Grid Output Switch” on don't restart inverter or battery, otherwise the function
will switch off outomatically.
Note: If Out-put Power Limit set as 0W, then there might still have deviation max 100W exporting to grid.
