General Operation

The inverter is equipped with a multi-channel MPPT, so you can always utilize maximum power even under varying conditions of your solar modules. It efficiently converts the generated direct current into grid-compliant alternating current and feeds it directly into the power grid. An integrated surge protector on both the AC and DC sides reliably protects the inverter from power surges and increases the operational safety of your system.

200% PV Oversizing

You can connect solar modules that, together, have up to twice the power output of the inverter itself. If your inverter has a capacity of 50 kW, you can connect solar modules with a total capacity of up to 100 kWp. This allows you to generate more electricity even when there is less sunlight or on cloudy days. Although the maximum power the inverter can deliver to your home remains the same, you’ll reach this peak power more frequently. This allows you to get more out of your solar system overall and increase your electricity yield throughout the year.

IV Curve Scan

The scan is an automatic diagnostic function that measures the current-voltage characteristic curve of your PV modules. This allows for the early detection of power losses, soiling, or defects without the need for additional measuring devices. This simplifies maintenance, increases operational reliability, and ensures maximum energy yields from your system.

Various Operating Modes

In on-grid operation, you can choose from six different operating modes: Self-Consumption, Feed-in Priority, Backup, Peak Shaving, Schedule, and EPS. Manual operation is intended solely for the customer service team. This allows you to flexibly adapt your energy supply to your daily routine and individual needs. In the event of a power outage, the system automatically detects the interruption and switches to EPS mode on its own. This ensures that important electrical appliances continue to be reliably powered.

Self-Consumption Mode
...is particularly suitable for regions where feed-in tariffs are low and electricity prices are high. In this mode, the solar power generated is primarily used for your own consumption. Excess energy first charges the battery. Only after your own needs are met and the battery is fully charged is the remaining electricity fed into the public grid. This way, you maximize your independence from the utility company and lower your energy costs.

Feed-in Priority
...is ideal for regions with attractive feed-in tariffs but where there is a limit on the amount of power that can be fed into the grid. In this mode, you first use the solar power you generate to meet your own needs. Any excess energy that you do not consume yourself is fed into the public grid. Note: Once the permitted feed-in limit is reached, the remaining energy is automatically used to charge the battery.

Backup Mode
...is ideal for locations with frequent power outages. In this mode, the system ensures that the battery always remains at a high state of charge. This allows you to continue reliably powering important devices during a power outage. Energy management in this mode follows the same principle as in self-consumption mode.

Peak-Shaving Mode
...is designed to help you specifically balance out peaks in electricity consumption. The system ensures that the battery is charged during periods of low electricity consumption. When electricity demand is high, the battery then provides energy to absorb load peaks. This allows you to make optimal use of your energy and reduce your electricity costs.

TOU Mode (Time-of-Use)
...using the SolaX Cloud app or the web, you can precisely specify how your system should operate at different times of the day. You can divide the day into up to 24 time slots, with each slot lasting at least 15 minutes. For each time slot, you can individually select whether the system should switch to, for example, self-consumption, charging, discharging, peak load operation, or battery shutdown. This allows you to optimally tailor your energy management to your daily routine and different electricity rates. Detailed setup instructions can be found in the Web Guide or in the app.

EPS (Off-Grid)
...In the event of a power outage, the system automatically takes over powering your most important devices (EPS loads)—either directly with solar power or with energy from the battery. This requires that a battery be installed and that the connected devices do not exceed the battery’s maximum power output. The electricity generated by the solar system is first used to power the loads. Excess energy is used to charge the battery.

Smart Load Management and Scene Function

This feature automatically and efficiently manages your household’s electricity consumption. The system continuously monitors how much electricity is currently being used and how much solar energy is being generated. It can specifically activate high-power loads—such as heat pumps or electric vehicle charging stations—when a particularly large amount of solar power is available. This allows you to make the most of the electricity you generate yourself and reduce your reliance on expensive grid power. At the same time, smart load management helps prevent power spikes and ensures the battery is used efficiently. For you, this means your energy consumption is automatically adjusted so you save money and your solar system is used as efficiently as possible at all times—without any extra effort on your part.

The “Scenes” feature lets you set up smart workflows and automations for your energy management. With this feature, you can define how the system should respond in specific situations or at specific times. For example, you can set the system to automatically charge the battery when a particularly high amount of solar power is being generated, or to supply power to certain devices only when electricity prices are low. Automatic switching between different operating modes is also possible. This allows the system to adapt optimally to your individual needs and energy consumption, ensuring efficient use of your solar system.

Microgrid

Normally, grid-tied inverters do not supply power when the public grid goes down—even if your solar system continues to generate energy. The microgrid function of the AELIO series solves this problem. It simulates its own power grid, thereby activating your grid-tied inverter even during a power outage. If you connect the grid-tied inverter to the EPS port of the AELIO system, you can continue to use solar or battery power even when the public grid is unavailable. This ensures you have a reliable energy supply even during power outages.

Protection and Safety

• Overvoltage/undervoltage protection, overtemperature protection
• DC isolation protection, DC reverse polarity protection, DC feed-in monitoring
• Grid monitoring, feed-in current monitoring, fault current detection
• Active anti-islanding method
• AC auxiliary power supply (APS)
• Arc Fault Circuit Interrupter (AFCI) – optional

Arc Fault Detection (AFCI) — optional

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

SolaXCloud

SolaXCloud is a smart platform for managing your home energy. It provides you with 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.
