Note: All the errors about battery happen only on Lithium battery with BMS communication. • ERROR MASSAGE Utility Loss VAC Failure Not available of public grid power (power loss or on-grid connection fails) Grid voltage is not within permissible range Inverter does not detect the connection of grid Inverter detects that AC voltage is beyond the normal range required by the safety country FAC Failure Grid Efficiency is not within permissible range Inverter detects that Grid frequency is beyond the normal range required by the safety country 1. Make sure safety country of the inverter is set right 2. If safety country is right, then please check on inverter display if AC frequency (Fac) is within a normal range 3. If FAC failure only appear a few times and resolved soon, it should be caused by occasional grid frequency unstability. PV Over Voltage DC total voltage of PV string is too high The total voltage (short-circuit voltage) of each PV string is higher than the max DC input voltage of the inverter. Check PV string VOC is lower than Max PV Input Voltage of the inverter If VOC of PV string is high, please decrease panels to make sure VOC is with the max DC input voltage of the inverter. Over Temperature Temperature inside of the inverter is too high Inverter working environment leads to a high temperature condition 1. Try to decrease surrounding temperature 2. Make sure the installation complies with the instruction on inverter user manual 3. Try to close inverter for 15 mins, then start up again. Isolation Failure Ground insulation impedance of PV string is too low Isolation failure could be caused by multi reasons like PV panels are not grounded well, DC cable is broken, PV panels are aged or surrounding humility is comparatively heavy, etc. 1. Try to decrease surrounding temperature 2. Make sure the installation complies with the instruction on inverter user manual 3. Try to close inverter for 15 mins, then start up again. Ground I Failure Ground leakage current is over-high Ground I failure could be caused by multi reasons like neutral cable on AC side is not connected well or surrounding humility is comparatively heavy, etc. Check use multi-meter if there is voltage value (normally should be close to 0V) between earth 2.Make sure load power is higher than 150W a. battery will not discharge continuously unless load power is higher than 150W; b. If battery still not discharge when Meter power is higher than 150W, then please check EzMeter 3. Make sure SOC is higher than 1-DOD. Or if battery discharged to below 1-DOD, than battery will only discharge again when SOC charged to 20%+
1-DOD
/ 2 and SOC
#105% -DOD(if need battery discharge immediately, battery should be restarted) 4. Check on APP if it is set as charge time, during charge time, battery will not discharge (battery will charge in priority during coincident time of charge/discharge) Solution: No Discharge or Output From EM at Night Without PV or PV Power Lower Than Load Power: 1.Check if charge voltage on App (Set¹Basic Setting) is properly set (for lead-acid battery) as battery cannot charge if battery voltage reaches charge voltage. 2.Check if it is during discharge time set on App. 3.Check if battery is fully charged or not, or battery voltage reach “charge voltage” or not. Solution: Battery Not Charge When PV Power Higher Than Load Power: 1.Check if there is a fluctuation on load power; 2.Check if there is a fluctuation on PV power. Solution: High Power Fluctuation Battery Charge or Discharge: 1.Make sure BMS communication is OK on PV Master (for lithium batteries); 2.Check if CT connected in the right position and to right direction as on the user manual page 13; 3.Check if the total load power is much higher than PV power. Solution: Battery Does Not Charge • TROUBLESHOOTINGS + - + - To Back-Up Load To Public Grid ◈ 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 right, please set it right in “Set” (Pic 35) NOTE
 1.For lead-acid battery: All the settings should comply with the parameter of the battery, and please contact GoodWe for advices 2.For lithium batteries, BMS status is “Communication OK” If APP BMS Status on APP says “NG” or “NA”, please check if battery wiring and settings are all right following battery connection SOP in EM QUICK INSTALLATION INSTRUCTIONS 3. Make sure CT is connected on the same phase with the power cable of EzMeter. Com (Blinking) RUN (Solid) R-P (Solid) ---- Pic 34 Pic 35 OTHERS OTHERS 23 24 Questions 2.
