System FAQ
Plan the Right Configuration.
What does this system collection include?+
The collection covers BSE small-scale, BSR residential, BSC commercial and BSI industrial energy storage proposals. Depending on the configuration, packages combine solar modules, an inverter or PCS, LiFePO4 batteries, monitoring and supporting electrical components.
Are all configurations the same type of system?+
No. The portfolio includes compact inverter-and-battery packages, three-phase hybrid systems, cabinet arrays and containerized storage. AC system power and DC battery capacity are different specifications and should be selected together.
Can I change the PV array or battery capacity?+
The proposal provides standard configurations as a starting point. Final PV sizing, battery capacity, backup duration and supporting equipment are selected for the site load and operating requirements.
Does the DC container include an AC inverter?+
The 4179.96kWh liquid-cooled container is a DC battery storage product. It requires compatible power conversion and site controls to form an AC energy storage system.
Which electrical market is this proposal for?+
This collection is based on the European Voltage Storage System Standard Proposal, version 2609. Review the individual configuration for its voltage and frequency, then confirm local grid and installation requirements.
