not modify the firmware file name, otherwise, the inverter
may not work!

greater than 100 V (upgrade on sunny days). please ensure
that the battery SOC is greater than 20% or the battery
input voltage is greater than 90 V. 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 power off the inverter and restart it.
Then repeat the upgrade steps.
-If the DSP firmware upgrade fails or stops, please check
whether the power is off. If it is normal, plug in the U disk
again and repeat the upgrade.
