150 kW / 330 kWh Solar Storage for the Eigenmann Farm in Berg, Switzerland

YOTAI PARTNER REFERENCE · YINTU ENERGY SOLUTIONS

The Eigenmann farm in Berg, Switzerland, is presented by YOTAI as a grid-connected solar-storage application with a stated project scale of 150 kW / 330 kWh. Its operating goals centre on using more local PV, limiting grid import and retaining stored energy for an agreed reserve purpose.

Project at a Glance

Customer Situation and Energy Requirements

The source describes high daytime electricity expenditure and PV output that the farm's simultaneous loads could not always absorb. Agricultural operations may have demand patterns that vary with work schedules or seasons, making the timing of generation and use important to storage planning.

The reference also calls for an import-power limit at the main connection. Storage must therefore respond to the site's overall power exchange, rather than operate only from its own terminal measurements or a fixed charging timetable.

Storage Integration and Control Strategy

The described architecture combines grid-side PV, storage, the utility and farm loads. The source prioritises local energy use: when PV and permitted battery discharge can meet demand, the operating goal is to avoid additional grid import. Export control and peak management are also listed requirements.

This control priority needs a clear SOC policy. A reserve held for continuity may reduce the energy available for daily demand reduction, while a full battery can limit the ability to absorb further solar production. A new project should define how these objectives share the battery.

The slide lists 150 kW / 330 kWh but also gives a single-unit quantity for the 110 kWh family. Those entries are inconsistent. This article retains the stated project scale and leaves the equipment quantity open for technical clarification, rather than deriving a count or changing either figure.

Intended Operational Value

The project illustrates how a farm can use storage to coordinate local generation and a constrained or commercially managed grid connection. Its intended value comes from moving useful solar energy into later demand periods and moderating selected import peaks.

The collection does not provide seasonal generation records, usable AC-energy tests or a measured savings result. These inputs are needed to estimate the benefit of a comparable farm installation and to agree an appropriate reserve policy.

Planning a Comparable Installation

• Measure farm demand and solar generation across relevant seasons.
• Confirm the connection limits and the location of the site meter.
• Resolve the original equipment schedule before using the reference as a bill of materials.
• Define which farm services need reserve energy and how that reserve is restored.

Related YINTU Storage Options

For a new solar-led farm project, YINTU can evaluate the 50 kW / 150.5 kWh hybrid ESS against the required electrical architecture. This catalogue model has different ratings from the reference equipment. The Swiss Alps farm microgrid case offers a separate agricultural reference with an explicitly off-grid operating objective.

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 seasonal load records, PV generation, connection limits, reserve requirements and the verified equipment schedule. 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 this the same installation as the Swiss Alps off-grid farm case?

The collection identifies the Eigenmann site in Berg and a grid-connected architecture. It is a separate reference from the remote Swiss Alps farm material.

Does the 330 kWh figure define guaranteed backup duration?

Duration depends on usable energy, the actual protected load, losses and operating limits. The source does not provide a tested backup-duration value.
