125 kW / 261 kWh Hybrid ESS for Existing Commercial PV Sites

YINTU is an energy storage solution provider working with capable manufacturing partners. We coordinate configuration selection and technical interfaces for the customer’s project.

Selected equipment and configuration

Retrofit objective

This application is for a commercial site that already has grid-connected PV and wants to add storage without redesigning the entire power supply. First map the existing PV inverter, meter, transformer and essential-load circuits. The 125 kW cabinet integrates LFP storage, PCS, BMS, EMS and a direct PV input, with a generator port available in the source configuration.

Choose the integration route

If the existing PV inverter stays on the grid-side AC bus, meter both PV production and grid exchange so the storage dispatch responds to the actual site balance. Export limitation needs a defined meter location, communication path and control settings. If selected arrays are to move to the cabinet’s DC input, check string voltage, current, isolation, earthing and the manufacturer-approved PV configuration. Confirm the MPPT option in the final order.

Backup boundary

An existing grid-following PV inverter may stop when the grid fails. Any requirement to operate that inverter on an islanded bus needs specific compatibility and protection approval. Establish which loads the cabinet serves, the isolation sequence, neutral arrangement and generator coordination on the single-line diagram. The source’s switching value is a component specification and must be validated with the installed loads.

YINTU project review

YINTU works with manufacturing partners to select equipment and coordinate the retrofit interfaces. Send the existing single-line diagram, inverter model and firmware, PV string schedule, interval loads and export permission. The quotation should identify supplied cabinet hardware, metering, transfer equipment, installation and commissioning responsibilities.
