Huawei Luna 2000 - possible to integrate locally?

Hi! I’m about to mount a photovoltaic setup, and I’ve been offered HUAWEI SUN 2000-6KTL-M1 inverter with Huawei Luna 2000-7KWh-C1 storage, Huawei DTSU-666-H counter and Luna 2000 batteries

How does it integrate with HA, is it problematic?

Does it need to connect to Huawei API or is it possible to integrate locally?
