100 kW / 220 kWh Solar Storage for a Vehicle Service Centre in Wels, Austria

YOTAI PARTNER REFERENCE · YINTU ENERGY SOLUTIONS

A vehicle dealership and repair facility in Wels, Austria, appears in YOTAI's collection as a 100 kW / 220 kWh solar-storage project. The reference combines PV sources, battery storage, the grid and site loads, with self-consumption and controlled power exchange as its main operating goals.

Project at a Glance

Customer Situation and Energy Requirements

The facility had substantial daytime electricity demand and a PV installation whose output could exceed local consumption at certain times. This creates two different operating needs: retaining useful solar energy and reducing selected grid-import peaks.

Vehicle service activities can also produce variable demand. A comparable project should measure the real workshop load profile instead of assuming that PV production and business opening hours always match. The source does not publish a circuit-by-circuit load schedule for this facility.

Storage Integration and Control Strategy

The collection describes both PV and grid-side PV in the system architecture. A coordinated controller must observe total site power exchange while dispatching storage and managing the supported generation interfaces. The stated priority is to avoid drawing from the grid when PV and available battery discharge can serve the load.

The reference gives a 30 kW maximum export value for an operating condition in which the battery is not full. It describes a software-based site control approach. This project-specific condition should not be treated as a general export permission for another installation.

A complete operating plan also needs to address a full battery, unavailable communications and sudden changes in workshop demand. Available battery charging power and the ability to reduce PV output determine how the system can remain within its agreed connection limits.

Intended Operational Value

The intended benefit is to retain more PV generation for business use while controlling demand at the grid connection. Stored energy may also form part of a backup design where the load circuits, switching and protection have been specified.

The presentation does not publish measured self-consumption improvement, savings or a transfer-time result. These remain project evaluation and acceptance-test questions, rather than outcomes that can be inferred from the 100 kW / 220 kWh rating.

Planning a Comparable Installation

• Identify how each PV source connects to the site electrical network.
• Confirm the import limit and all conditions attached to the export allowance.
• Use interval load data to size peak support and battery reserve.
• Agree the full-battery and PV-curtailment sequence before commissioning.

Related YINTU Storage Options

YINTU can assess a comparable site using the 50 kW / 115.2 kWh AC-coupled commercial cabinet or a separately engineered alternative. The linked product differs from the case's 110 kWh equipment family. Review the commercial storage project budget guide to include metering, switchgear and control integration alongside the cabinet cost.

How YINTU Supports a Comparable Project

YINTU is an energy storage solution provider working with manufacturing partners, including YOTAI. We support application assessment, equipment selection and technical coordination for customer-specific projects. This article presents a supplier reference. YINTU does not claim to have designed or installed the featured site.

For a new proposal, share workshop demand profiles, PV inverter details, the import/export agreement and backup priorities. The agreed technical scope defines equipment, interfaces and service responsibilities. The source's 110 kWh equipment family should not be treated as identical to a current catalogue product with a different rating.

Project Questions

Is the stated 30 kW export setting a universal design value?

It is a value from this supplier reference under a stated operating condition. The connection agreement and controller design determine the limits for a new project.

Do two cabinets guarantee twice the output under every condition?

The source lists two units and a project total. Actual parallel operation must remain within equipment, battery, grid and protection limits.
