A Complete SolaX Energy System in Düsseldorf

Project Overview

A homeowner in Düsseldorf, Germany has taken a major step toward an integrated home energy system by choosing SolaX across multiple energy applications.

Already using SolaX inverters, battery storage and an EV charger, the homeowner wanted to further simplify his home energy setup by replacing his old gas heating system with a SolaX Thermal 290 Heat Pump.

With solar energy, battery storage, EV charging and heating now brought together under the SolaX ecosystem, the project demonstrates how a residential energy system can evolve from solar and storage into a more complete whole-home energy solution.

System Configuration

The Düsseldorf home is equipped with a comprehensive SolaX residential energy solution covering electricity generation, energy storage, EV charging and heating.

• Location: Düsseldorf, Germany

• Application: Residential energy management

• Hybrid Inverter: X3-HYB G4, 6 kW + X3-HYB G4, 12 kW

• Battery Storage: T58 V2 battery (2 battery groups: 8 modules + 4 modules)

• EV Charger: SolaX X1-X3-EVC

• Heating System: SolaX Thermal 290 Heat Pump

The system integrates multiple energy technologies within the same SolaX ecosystem, helping the homeowner manage solar power, battery storage, EV charging and home heating as part of a more unified energy setup.

From Solar Storage to Whole-Home Energy

The homeowner's journey with SolaX started with solar and energy storage. With SolaX already trusted as the core of the home's electricity system, adding EV charging was a natural next step.

The introduction of SolaX's heat pump solution provided an opportunity to take the system even further.

After discovering the SolaX Thermal 290 Heat Pump online, the homeowner contacted his installer and specifically requested a SolaX solution to replace the home's old gas heating system.

This customer-led decision highlights an important trend in residential energy: homeowners are increasingly looking beyond individual products and toward integrated energy ecosystems that can connect solar generation, battery storage, EV charging and heating.

“I've been very happy with my SolaX system for solar, battery storage and EV charging. When I discovered that SolaX also offers heat pumps, choosing SolaX for my home heating was a natural choice. I wanted one trusted brand across my entire energy system, and SolaX has given me confidence at every step.”

Project Benefits

One Integrated Energy Ecosystem

By choosing SolaX for multiple energy applications, the homeowner has created a more unified residential energy system covering solar PV, battery storage, EV charging and heating.

Replacing the Old Gas Heating System

The project replaces the home's previous gas heating system with a SolaX Thermal 290 Heat Pump, supporting the homeowner's transition toward a more electrified home energy setup.

Simplified Brand Ecosystem

Using SolaX across multiple applications allows the homeowner to work with a single energy technology provider rather than managing separate brands for solar, storage, EV charging and heating.

Confidence Built on an Existing SolaX Experience

The decision to install the SolaX heat pump was supported by the homeowner's existing experience with SolaX products. Having already chosen SolaX for his inverter, battery storage and EV charger, he was confident extending the same brand into home heating.
