6. Mode

Mode 2 with generator — Mode 2 With generator

The 1st priority power of the system is always the PV power, then 2nd and 3rd priority power will be the battery bank or grid according to the settings.
The last power backup will be the Generator if it is available.

Chart 7-1 Fault information

Error code	Description	Solutions
F01	DC input polarity reverse fault	1. Check the PV input polarity 2. Seek help from us, ifcan not go back to normal state.
F07	DC_START_Failure	1. The BUS voltage can’t be built from PV or battery. 2. Restart the inverter, If the fault still exists, please contact us for help
F13	working mode change	1. When the grid type and frequency changed it will report F1 2. When the battery mode was changed to “No battery” mode,it will report F13; 3. For some old FW version, it will report F13 when the system work mode changed; 4, Generally, it will disappear automatically when shows F13; 5. If still same, and turn off the DC switch and AC switch and wait for one minute and then turn on the DC/AC switch; 6. Seek help from us, if can not go back to normal state.
F15	AC over current fault of software	AC side over current fault 1. Please check whether the backup load power and common load power are within the range; 2. Restart and check whether it is in normal; 3. Seek help from us, ifcan not go back to normal state.
F16	AC leakage current fault	Leakage current fault 1. Check the PV side cable ground connection 2. Restart the system 2-3 times 3. if the fault still existing, please contact us for help
F18	AC leakage current fault	Leakage current fault 1. Check the PV side cable ground connection 2. Restart the system 2-3 times 3. if the fault still existing, please contact us for help.
F20	DC over current fault of the hardware	DC side over current fault 1. Check PV module connect and battery connect; 2. When in the off—grid mode, the inverter startup with big power load, it may report F20. Please reduce the load power connected; 3. Turn off the DC switch and AC switch and then wait one minute, then turn on the DC/AC switch again; 4. Seek help from us, if can not go back to normal state.
F21	Tz_HV_Overcurr_fault	BUS over current. 1. Check the PV input current and battery current setting 2. Restart the system 2~3 times. 3. If the fault still exists, please contact us for help.
F22	Tz_EmergStop_Fault	Remotely shutdown 1. it tells the inverter is remotely controlled.
F23	Tz_GFCI_OC_ current is transient over current	Leakage current fault 1. Check PV side cable ground connection. 2. Restart the system 2~3 times. 3. If the fault still exists, please contact us for help.
F24	DC insulation failure	PV isolation resistance is too low 1. Check the connection of PV panels and inverter is firmly and correctly; 2. Check whether the PE cable ofinverter is connected to ground; 3. Seek help from us, if can not go back to normal state.
F26	The DC busbar is unbalanced	1. Please wait for a while and check whether it is normal; 2. When the load power of 3 phases is big different, it will report the F26. 3. When there’s DC leakage current, it will report F26 4. Restart the system 2~3 times. 5. Seek help from us, if can not go back to normal state.
F29	Parallel CAN Bus fault	1. When in parallel mode, check the parallel communication cable connection and hybrid inverter communication address setting; 2. During the parallel system startup period, inverters will report F29. But when all inverters are in ON status, it will disappear automatically; 3. lf the fault still exists, please contact us for help.
F34	AC Overcurrent fault	1. Check the backup load connected, make sure it is in allowed power range. 2. If the fault still exists, please contact us for help.
F41	Parallel system stop	1. Check the hybrid inverter work status. If there is lpcs hybrid inverter shutdown, all hybrid inverters will report F41 fault. 2. lf the fault still exists, please contact us for help.
F42	AC line low voltage	Grid voltage fault 1. Check the AC voltage is in the range of standard voltage inspecification; 2. Check whether grid AC cables are firmly and correctly connected; 3. Seek help from us, ifcan not go back to normal state.
F46	backup battery fault	1. Please check each battery status, such as voltage/ SOC and parameters etc., and make sure all the parameters are same. 2. If the fault still exists, please contact us for help.
F47	AC over frequency	Grid frequency out ofrange 1. Check the frequency is in the range of specification or not; 2. Check whether AC cables are firmly and correctly connected; 3. Seek help from us, ifcan not go back to normal state.
F48	AC lower frequency	Grid frequency out ofrange 1. Check the frequency is in the range of specification or not; 2. Check whether AC cables are firmly and correctly connected; 3. Seek help from us, if can not go back to normal state.
F55	DC busbar voltage is too high	BUS voltage is too high 1. Check whether battery voltage is too high; 2. Check the PV input voltage, make sure it is within the allowed range; 3. Seek help from us, if can not go back to normal state.
F56	DC busbar voltage is too low	Battery voltage low 1. Check whether battery voltage is too low; 2. If the battery voltage is too low, using PV or grid to charge thebattery; 3. Seek help from us, if can not go back to normal state.
F58	BMS communication fault	1. it tells the communication between the hybrid inverter and battery BMS disconnected when “BMS_Err-Stop” is active” 2, if don’t want to see this happen, you can disable “BMS_Err-Stop” item on the LCD. 3. lf the fault still exists, please contact us for help.
F62	DRMs0_stop	1. the DRM function is for Australia market only. 2. Check the DRM function is active or not 3. Seek help from us, if can not go back to normal state after restart the system.
F63	ARC fault	1. ARC fault detection is only for US market; 2. Check PV module cable connection and clear the fault; 3. Seek help from us, if can not go back to normal state.
