SolaX EV charger X1-HAC-7S G2 7.2 kW smart wallbox, single-phase

The SolaX X1-HAC-7S G2 single-phase EV charger with 7.2 kW (MPN: 1050010351) uses excess solar power without feeding electricity into the public grid—the so-called zero-export system. This allows you to maximize the self-consumption rate of your solar system and make your charging infrastructure particularly efficient. The wallbox thus fully supports the charging of your electric vehicle. It is permanently installed at a single location and connected directly to the power grid. Thanks to its integrated communication interfaces, it can work in conjunction with other devices such as inverters, electricity meters, current transformers, or external charging management platforms. With the integrated RFID management, you can control access precisely and ensure that only authorized users can charge. The remote control function also allows you to conveniently monitor and control the charging process remotely at any time. The charger is thus a future-proof solution for renewable and independent e-mobility.

Multiple options in the HAC series

Since there are different types of chargers in the X1-HAC and X3-HAC series, here’s a brief explanation:

• X1 - Single-phase
• HAC - Series name
• 7–7 .2 kW R rated output power
• "S" – Outlet type, outlet only

With this socket-type (“S”) variant, no permanently attached charging cable is included. You’ll therefore need your own Type 2 cable to charge your car. However, this also gives you maximum flexibility when charging different vehicles.

Automatic Phase Switching

With automatic switching between single-phase and three-phase operation, your energy system flexibly adapts to current demand at all times. When power consumption is low, the system operates in single-phase mode and uses the generated solar energy particularly efficiently. As soon as higher power is required—for example, when multiple large appliances are running simultaneously—the system automatically switches to three-phase mode. This ensures that the available solar power is optimally distributed across all phases, reliably powering even high-power devices.

Interoperability

The system is compatible with multiple communication protocols. This allows it to connect seamlessly with various inverters, battery storage systems, and monitoring units. The broad protocol support ensures that all components of your solar system communicate reliably with one another, regardless of manufacturer or system type. This allows you to flexibly integrate the system into existing setups or expand it easily as needed.

Dynamic Load Balancing

The system continuously monitors all relevant operating data of your solar system—such as voltage, current, and temperature—in real time. In the event of deviations or unusual values, it reacts immediately and automatically adjusts the settings to avoid potential risks. This allows overloads, overheating, or other malfunctions to be detected early and prevented.

Parallel Function

The parallel function allows you to operate multiple EV chargers on the same circuit. In a solar system, two chargers can be used in parallel. The primary unit controls the distribution of solar and grid power, while the secondary unit automatically follows its settings. In standard applications, up to 20 chargers can be connected in parallel, with one unit taking over control and distributing the charging power evenly. This allows you to control all charging points centrally and efficiently.

Safety and Protection

• Overvoltage/Undervoltage Protection
• Overtemperature Protection
• Short-circuit protection
• Overload protection
• Grounding protection
• Cable protection—cable lock (app control)
• Relay protection—Real-time weld seam detection
• Ground Fault Protection - Integrated Power Outage Monitoring

Smart App Control

With the SolaX app, you have access to all important data about your solar system anytime, anywhere. You can view the current energy yield, consumption, and the status of individual components in real time. In addition, the app allows you to adjust settings directly from your smartphone—for example, to switch operating modes or receive notifications in case of malfunctions. The user interface is clearly laid out, so you can quickly find and easily use all functions.

SolaXCloud

SolaXCloud is a smart platform for managing your home energy. It provides clear monitoring of your energy consumption and power generation, as well as easy control of all connected devices. This allows you to optimize the efficiency of your electricity consumption and get the most out of your solar system. Your data is transmitted securely and reliably at all times. With the Monitoring Cloud app, you can conveniently monitor your photovoltaic system via Wi-Fi, LAN, or 4G. You can view alerts, adjust settings, and manage maintenance. To do this, plug the dongle into the inverter’s USB port. Once powered on, you can connect to the app immediately. You’ll find the QR code to download the app in the user manual.
