500 kW / 1 MWh Air-Cooled ESS for External PV Inverter Retrofits

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

Selected hardware boundary

This listing selects the 500 kW / 1000 kWh air-cooled configuration. Its source specifies an external PV inverter and leaves internal MPPT parameters blank for this variant. The container integrates battery, PCS, BMS, EMS and a generator port. This is an AC-interface planning option for a site that already has solar conversion equipment.

Existing-site integration

Survey the PV inverter models, transformer rating, AC feeder protection and export restrictions. Set the measurement boundary so the controller sees grid exchange and any relevant PV production. Confirm who supplies the meter, communication gateway and grid protection. Size storage dispatch from the combined production and load trace, checking both the 500 kW power limit and energy over the required period.

Plan islanded operation separately

The source lists on-grid and off-grid modes for the ESS. Existing PV inverters require explicit approval for operation on an islanded bus, including curtailment and protection behavior. Determine which generator and loads are connected to that bus and agree the transfer sequence. Validate the complete installation’s behavior during loss of grid and communications.

YINTU retrofit review

YINTU helps coordinate the container and the interfaces supplied by manufacturing partners and the EPC. Share the existing single-line diagram, PV inverter data and required backup sequence. The external PV inverter, grid protection, transformer, site installation and commissioning are defined in the final project scope.
