For compatible lithium batteries, BMS status is "communication OK" after
selecting the right battery company.

Battery Connection:
Confirm the connection between BT and battery : polarities ( +/-) not
reversed, refer to Figure 4.1-1
•
On-Grid & Back-Up Connection:
Confirm ON-GRID connected to power grid and Back-Up to
loads: polarity (L1/L2/L3/N) not reversed, refer to Figure 4.1-2.
•
Smart Meter & CT Connection:
Make sure Smart Meter & CT are connected between house
loads and grid, follow the Smart Meter direction sign on CT, refer to Figure 4.1-3.
BT not Start Up With Only Battery
Solution:
Make sure the voltage of battery is higher than 180V, otherwise battery cannot start BT up
High Power Fluctuation on Battery Charge or Discharge:
Solution:
Check if there is a fluctuation on load power.
Battery Does Not Charge:
Solution:
1. Make sure BMS communication is OK on PV Master.
2. Check if CT connected in the right position and to right direction as on the user manual page 12
3. Check if the total load power is much higher than PV power.
About Wi-Fi Configuration
Q: Why cannot see Solar-WiFi* signal on mobile devices
A: Normally Solar-WiFi* signal could be searched right after inverter powered up. But Solar-WiFi
signal will disappear when BT connected to internet. If need to change settings, can connect to the
router to change. If cannot see Wi-Fi signal even not connect to router, then please try to reload
Wi-Fi (please refer to BT user manual page 17).
Q: Why cannot connect Solar-WiFi* signal on my phone?
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.
About Battery Operation
Q: Why battery does not discharge when grid is not available, while it discharges normally when
grid is available?
A: On APP, Off-Grid output and Back-Up function should be turned on to make battery discharge
under Off-Grid mode.
Q: Why there is no output on Back-Up side?
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 turned on as well.
Note: As turn “Off-Grid Output Switch” on, don’t restart inverter or battery, otherwise the function will
switch off automatically.
Q: On Portal, why battery SOC has a sudden jump up to 95%?
A: This normally happens on when BMS communication fail on lithium. If battery enter float charge,
SOC will be reset to 95% compulsively.

Battery Settings, BMS Communication and Safety Country:
After connecting Solar-WiFi*
(* means the last 8 characters of the inverter serial No.), check on PV Master APP Param to make
sure battery type is right what you have installed, and Safety Country is right. If not, please set it right
in “Set” .(Figure 4.1-4)
