Product details
Product information "B-Box HVB 20.7 + GW20K-ET"
The manufacturer's specifications regarding the installation site, assembly, installation, assembly tools, fire protection, safety clearances, etc., must be verified and confirmed by the customer prior to installation.
Please check whether additional third-party loggers or EMS units are required for the specified interfaces within the overall system (existing + new).
The communication dongle included in the scope of delivery meets cybersecurity requirements.
The RJ45 data bus terminating plug included in the scope of delivery requires final assembly on-site. To do this, a wire jumper must be inserted and crimped between pins 1 and 6 (viewing the flat side of the connector with the pin contacts from above, with the cable entry facing downwards and pins numbered from left to right). An actual resistor is not required.
This storage package from GoodWe and BYD is the ideal system component for a wide range of small commercial applications. The HVB high-voltage battery can be cascaded up to three times, enabling flexible system configurations with a maximum capacity of 89.07 kWh. With up to three MPP trackers and high input currents, the inverter provides the necessary flexibility to implement various scenarios—such as self-consumption optimization, peak shaving, and time-of-use strategies. Thanks to the integrated backup function, reliable switching at UPS-level standards is guaranteed, even for sensitive loads.
