Frequently Asked Questions
Practical answers for your C&I project
Key questions before site assessment and system sizing.
How do I choose between 30kW and 50kW?
The choice depends on measured loads, peak demand, available PV generation and the required storage duration. A site assessment confirms the configuration.
Can the system work with a diesel generator?
A compatible EMS and power-conversion design can coordinate storage with an existing generator. The electrical design must be checked for the site.
Can storage work without solar PV?
Yes, a suitably designed battery system may charge from the grid. The configuration depends on local rules and project goals.
Can several systems be connected in parallel?
Parallel operation depends on the selected hardware, electrical design and controls. Bluesun can assess the site requirements.
Can the system support loads during an outage?
Backup capability requires the appropriate power conversion, switching and critical-load design.
What are the installation requirements?
Requirements depend on system size, site preparation, electrical connection, local permits and fire-safety rules.
