Now I am looking for HV-PV storage equal to 30 kWh and larger. Compatible with my hybrid inverter SOFARSOLAR ME 20KTL-3PH . The installation should also be simple. About ALIBABA I have found this.
In the Photovoltaikforum there are also entries about it. Register and search.
These manufacturers I have found:
BLUESUN BST-30.0HV Stacked HighVoltage 30KWH offer port Stgt. under 6000€.
BLUESUN Hybrid Inverter Battery Connect Guide
ASGOFT ASGOFT high voltage LiFePO4 battery 20KW 25KW 30KW 40KW battery energy storage battery solar power storage system for house offer ALIBABA offer 40 kWh 7.850,00 $ ca.:7.362,20 Euro without delivery costs ( request was made to the Hamburg office)
According to information very simple installation - documents were requested.
There are certainly still substantially more offerers - who found which - I take up these gladly.
