Step 1 (Optional) Log in to the app and replace the protocol version of the new SUN2000
with that of the old SUN2000.
● This step is required when you replace the SUN2000 of a dierent protocol version. For
example, when you replace the SUN2000-(8KTL-12KTL) with the SUN2000-
(3KTL-20KTL)-M0, you need to replace the protocol on the SUN2000-(3KTL-20KTL)-M0
with that on the SUN2000-(8KTL-12KTL).
● For details about inverter replacement details, contact Huawei service engineers.
