Note: a. Growatt 10-20kUE three-phase inverter has two types of fan structures. b. Growatt 10kUE, 12kUE has two fans while 18KUE, 20KUE has three fans on the top of inverter. Fan type 1 cleaning procedure: The left and top of shell plane is as entirety seamlessly. - Page 6 Fig.2.1.2 UE series inverter Fig.2.1.3 A View Fig.2.1.4 B View 3) Remove the handles on both sides of UE inverter as Fig.2.1.4 show. 4) Remove the shell plane of the bottom and right side. Use appropriate screwdrivers counterclockwise rotate the screws marked in Fig.2.1.5. Fig.2.1.5 5) Unlock and remove the plug connectors of cooling fans.
- Page 7 Fig.2.1.6 6) Remove the shell plane of the top and left side, as Fig.2.1.6 1 2 4 5 show. It’s easy to clean the grills on shell plane using water or some tools. 7) Clean the grills on shell planes. 8) Remove and clean the cooling fans.

Fan replacement is required if it fails to work. The procedure is similar to fan cleaning procedure; the difference is that broken fan should be exchanging before assembling the inverter in reverse order. Please contact Growatt service to get new one if there are some broken fans in inverter. Warning 103 Fail to read EEPROM. - Page 10 2.

PV Isolation Low PV input insulation impedance is too low. 1. Please confirm whether the output of inverter is connected according to user manual. 2. Please provide the model value shown as Fig.2.3.2 or Fig.2.3.3 to Growatt service. - 10 -... - Page 13 7. Disconnect PV terminals and measure the impedance between PV1+ and Earth, PV2+ and Earth, PV- and Earth by multi-meter; check whether all the impedances are beyond 1 Mega ohm, if not, please contact Growatt service. Note: Inverter shell is also grounded.

Earth PV1-/PV2- PV2+ PV1+ Fig.4.1.4 DC side in the inverter PV Voltage High PV voltage is over 1000V. 1. Turn off AC breaker, measure the string voltage between PV+ to PV- by multi-meter according to the mark on DC terminal shown as Fig.4.2.1 and check whether it is within DC voltage range. If it is higher than the Max allowed DC voltage 1000V, you need to reduce the quantity of PV modules. -

AC wiring condition (including length and diameter of cables etc.) and record whether assemble an isolated transformer on the output, and then contact Growatt service. Meanwhile you can check as following steps: Note: In this document, L1, L2, L3 means three phase live wire and N means neutral wire. - Page 17 Live wires Neutral Inside AC terminal Fig.4.5.2 Live wires Neutral Inside AC terminal Fig.4.5.3 6) Assemble the inverter in reverse order. 4. Turn on AC breaker, measure the real grid voltage (L1, L2, L3 to N) by multi-meter. 5. Check whether the grid voltage is complied with the local grid standards; check whether the grid voltage is stable with multi-meter.
- Page 18 Fig.4.5.4 If the AC terminal belongs to type 3 as Fig.4.3.1 show, please remove the shell of AC terminal by screwdriver and measure the corresponding phase voltage (R, S, T 3 phase) outside inverter as Fig.4.5.5. Fig.4.5.5 6. Turn on DC switch; compare the measured grid voltage with the AC voltage displayed on LCD. If the tolerance is more than 3V, please calibrate AC voltage of the inverter as following steps: R/S/T Fig.4.5.6 Output information interface...

AC F Outrange Grid frequency is out of range; Or the inverter’s frequency limits is incorrect. If there are several inverters in parallel, and the inverter shows “AC V Outrange” after the inverter feed to grid working for a while, perhaps the grid impedance is too high, please record the AC wiring condition (including length and diameter of cables etc.) and record... - Page 21 Fig.4.6.1 Power information interface 2. Check the grid frequency limits by ShineBus as following steps: 1) Select layout “4 Parameter”, select option “Read” as following figure. Fig.4.6.2 2) Select 15, 16, 19 and 20 option in “Set ID” drop-down list. And click button “Operate” to read the frequency limits one by one.
