LUXPOWERTEK-SNA3000-WPV-ECO-Hybrid-Inverter-012

Please refer to the connection diagram to determine the correct position of the Grid CT and securely attach it to the L wire at the service entry point in the main service panel. The arrow on the CT should point towards the inverter. (*** Incorrect installation of the CT may result in the display showing incorrect information, and the inverter features may not function properly.) If the CT is installed in the wrong direction, you can change the CT direction on your inverter by selecting “CT Direction Reversed” in the Advanced Tab. There is no need to make any physical changes.

CT Clamp Ratio
The inverter support 3 ratios of CT clamp- 1000:1 , 2000:1 and 3000:1 . The CT ratio of the CTs in the accessory bag is 3000:1. If you are using a 3rd party CT, please ensure the CT ratio is one of them, and select the correct CT ratio setting in the inverter monitor page or on the inverter LCD.

Trouble Shooting & Error List

The failures mainly divided into 5 categories, for each category, the behavior is different:

Code Description Trouble shooting
E000 Internal communication fault1 Restart inverter, if the error still

exist, contact us (DSP&M3)
E002| Bat On Mos Fail| Restart inverter, if the error still exist, contact us
E003| CT Fail| Restart inverter, if the error still exist, contact us
E008| CAN communication error in Parallel System| Check CAN cable connection is connected to the right COM port
E009| No master in parallel system| Check parallel setting for master/Slave part, there should be one master in the system
E012| UPS output short circuit| Check if the load is short circuit, try to turn off the load and restart inverter
E013| UPS reserve current| Restart inverter, if the error still exist, contact us
E015| Phase Error in three phase parallel system| Check if the AC connection is right for three phase system, there should one at least one inverter in each phase
E016| Relay fault| Restart inverter, if the error still exist, contact us
E017| Internal communication fault2| Restart inverter, if the error still exist, contact us (DSP&M8)
E018| Internal communication fault3| Restart inverter, if the error still exist, contact us (DSP&M3)
E019| Bus voltage high| Check if PV input voltage is higher than 480V
E020| EPS connection fault| Check if EPS and AC connection is in wrong terminal
E021| PV voltage high| Check PV input connection and if PV input voltage is higher than 480V
E022| Over current internal| Restart inverter, if the error still exist, contact us
E024| PV short| Check PV connection

E025

|

Temperature over range

| The internal temperature of inverter is too high,

turn off the inverter for 10minutes, restart the inverter, if the error still exist, contact us

E026| Internal Fault| Restart inverter, if the error still exist, contact us (Bus sample)

E028

| Sync signal lost in parallel system| Check CAN cable connection is connected to the right COM port

E029

| Sync triger signal lost in parallel system| Check CAN cable connection is connected to the right COM port
E031| Internal communication fault4| Restart inverter, if the error still exist, contact us (DSP&M8)
