Firmware Upgrading

-In order to upgrade the firmware smoothly, if the DSP and ARM firmware needs to be upgraded, please note that ARM firmware must be upgraded
first, then DSP firmware!

-Make sure that this directory is completely consistent with the above table, do not modify the firmware file name,Otherwise, the inverter may not work!

-For X1-Hybrid G4, ensure that the PV input voltage is greater than100V (upgrade on sunny days). please ensure that the battery SOC is greater than 20%

or the battery input voltage is greater than 90V. Otherwise, it may cause serious failure during the upgrade process!

-If the ARM firmware upgrade fails or stops, please do not unplug the U disk and power off the inverter and restart it. Then repeat the upgrade steps.

Ø

Upgrade p reparation

1) Please check the inverter version and prepare a U disk (USB 2.0) and personal computer before upgrading.

2) Please contact our service support through [e-mail] to obtain the firmware, and store the firmware in the U disk according to the
following path.

Update:
For ARM file:“update \ARM\618.00361.00_Hybrid_X1G4_ARM_V1.01.0710.usb”;
For DSP file:“update\DSP\618.00360.00_Hybrid_X1G4_DSP_V1.01.0710.usb”;
