It ensures that only the permitted amount of electricity is fed into the public grid, up to zero feed-in. A SolaX Energy Meter measures your household consumption in real time, and the inverter adjusts its power automatically. Self-consumption first, feed-in limits such as 70% or a fixed kW value are reliably maintained. External controllers are not necessary; the correct installation of the electricity meter and the appropriate country or grid configuration in the device are important.

This means that in the X3-PRO-G2, a digital signal processor monitors and controls the power electronics in real time. It reacts very quickly to changing conditions, optimizes the MPP, keeps the output voltage clean and efficient, and implements grid requirements precisely. For you, this results in: more yield, high efficiency, quiet operation, and reliable protection in case of faults.

• 150% DC oversizing, 110% AC power

150% DC oversizing means that you may connect 1.5 times more module power at the PV input than the inverter has as AC nominal power. This increases the yield in low light. Power peaks are then possibly "clipped" to the inverter limit. 110% AC overload output means the inverter can briefly feed in up to about 22 kW (at 20 kW AC nominal power). It is crucial to observe the MPPT limits for voltage, input current and short-circuit current (including Voc at lowest temperatures) as well as thermal conditions and grid requirements.

The inverter automatically checks the entire permissible voltage range of your PV strings and selects the actually best operating point. This prevents yield losses due to partial shading, different orientations or soiling and reliably increases the electricity yield. The scan runs automatically at defined intervals (e.g. at start-up) and can slightly change the power for a short time – additional hardware is not required.

Here your electricity consumption in the household is controlled automatically and efficiently. The system continuously monitors how much electricity is currently being consumed and how much solar energy is being generated. It can specifically activate large consumers such as heat pumps or charging stations for electric cars when a lot of solar power is available. This way you use your self-generated electricity optimally and reduce the purchase of expensive grid electricity. At the same time, intelligent load management helps to avoid power peaks and use the battery sensibly. For you, this means: Your energy consumption is automatically adjusted so that you save costs and your solar system is used as efficiently as possible at all times – without any additional effort.

• Parallel connection

The series inverter is parallel-capable. You can connect several devices to form a system and control the feed-in together, up to zero feed-in. A SolaX meter installed in the main circuit (at the grid connection point) measures the energy flow, and the inverters regulate their power synchronously. The coupling is done either via Modbus or the DataHub (to be purchased separately). Please observe the circuit diagrams specified by the manufacturer as well as correct wiring and addressing.

• Protection and safety
• AFCI - Optional
• Anti-islanding protection
• DC reverse polarity protection
• Insulation monitoring
• Residual current monitoring
• Overheating protection

AC overcurrent protection, short-circuit protection, overvoltage protection

• Arc fault detection (AFCI) - optional

If your PV modules, connectors or cables are incorrectly installed or damaged, so-called arcs can occur, which can cause fires. To quickly prevent such fires, SolaX has developed an optional arc fault detection. This function can be installed and ensures a higher level of safety for you and your PV system.

• SolaXCloud

SolaXCloud is an intelligent platform for managing your home energy. It offers you a clear monitoring of your energy consumption and electricity generation as well as simple control of all connected devices. This optimizes the efficiency of your electricity consumption and gets the best out of your solar system. Your data is always transmitted securely and reliably. With the Monitoring Cloud App you can monitor your photovoltaic system conveniently via Wi-Fi, LAN or 4G. You can view alarms, adjust settings and control maintenance. To do this, plug the dongle into the USB port of the inverter. After switching on, the connection to the app is immediately possible. You can find the QR code for downloading the app in the user manual.
