The inverter in the grid-connected system

The inverter is an essential component of your PV system. It efficiently converts the direct current generated by the solar modules into alternating current, which is required for use in households and businesses. Thanks to its three-phase, transformerless design, it ensures stable and powerful energy conversion. The direct current (DC) generated is converted directly into grid-compliant alternating current (AC) and fed into the public power grid. Integrated surge protection on the AC and DC sides reliably protects your system from damage caused by lightning strikes or voltage spikes. This allows you to benefit from the safe and efficient use of your solar energy.

150% PV oversizing, 110% output overload

Oversizing allows you to install solar modules with up to 1.5 times the rated power of your inverter. This means you can achieve a higher electricity yield even when there is little sunlight. Thanks to output overload, it can provide more power than its rated power for a short period of time. This allows you to make optimal use of power peaks and increase the efficiency of your PV system.

Options for parallel connection

With the SolaX Datahub, you can flexibly expand the capacity of your system by connecting up to 60 inverters in a single system. It enables smooth parallel operation and ensures that all inverters work together optimally. Thanks to the integrated electricity meter in the main circuit, zero feed-in is possible. This means that surplus electricity is not fed into the public grid. The Datahub takes over central control and ensures reliable communication between all connected inverters.

Possible areas of application

• Large-scale photovoltaic systems
• Industrial applications
• Charging infrastructure for electric mobility
• Agricultural businesses
• Off-grid and hybrid systems

Reactive power compensation

Reactive power compensation during nighttime operation makes it possible to actively contribute to the stability of the power grid even without solar power. It can specifically feed reactive power, a special form of electrical energy, into the grid or absorb it. This function is crucial for ensuring that the power grid functions reliably and that the grid operator's specifications are met. This means that your system is optimally prepared for current and future requirements.

I-U characteristic curve diagnosis

This function ensures that your inverter regularly checks how much electricity your solar modules generate at different voltages. This allows the system to detect early on if individual modules are performing less efficiently—for example, due to dirt, aging, or technical defects. You will be informed in good time if there are any malfunctions and can react quickly. This ensures that your system remains efficient and reliable in the long term.

Integrated export power control function

You can precisely control how much electricity from your solar system is fed into the public grid. You can completely prevent feed-in (zero feed-in) or limit it to a desired value. The inverter regulates this automatically and continuously adjusts the feed-in to your specifications. This allows you to easily meet the requirements of your grid operator and make optimal use of your system's self-consumption – without any additional accessories.

Arc fault detection (AFCI)

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

SolaXCloud

SolaXCloud is an intelligent platform for managing your home energy. It provides you with a clear overview 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 power 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 alarms, adjust settings, and control maintenance. To do this, plug the dongle into the USB port of the inverter. Once switched on, you can connect to the app immediately. You will find the QR code for downloading the app in the user manual.
