Why GRES Storage?

LiFePO₄ Quality Cells

≥ 5,000 cycles, 25-year design life, high cell-level safety

Outdoor IP54

Operation from −20 °C to +55 °C, no foundation required, low maintenance

Integrated BMS + Cloud

Three-stage protection, remote monitoring, data analytics

Bidirectional PCS

Peak shaving, arbitrage, grid feed-in, load management

Grid Connection

Aligned with VDE-AR-N 4105 / 4110 and TAR rules

Service in Germany

Authorised service dispatch point, on-site support

Compliance and Standards

VDE-AR-N 4105 / 4110 TAR ISO 9001 / ISO 14001 (manufacturer)

Grid connection rules depend on the connection case, voltage level and local grid operator. ISO management-system certificates apply to the manufacturer. Detailed product-level conformity documents on request.

Where Commercial Storage Fits

Manufacturing

Demand peaks and demand-charge exposure can be reviewed with measured load data.

Logistics & Haulage

Charging fleets at the existing grid connection where capacity allows.

Retail & Property

PV self-consumption can be examined per site, depending on load and PV profile.

Utilities

Grid-service participation depends on metering, market access and operating concept.

Charge Point Operators

Add charging power within an existing connection budget where the load profile allows.

Economics: What Drives the Business Case?

Load profile

as a basis

kW / kWh

sized separately

Tariff sheet

checked per project

A defensible business case needs measured load data, the grid operator tariff sheet and the planned operating strategy.
