SolaX X3-HYBRID G4 Hybrid Inverter 15kW X3-Hybrid-15.0-D 3-phase

The 3-phase X3-HYBRID G4 from SolaX (MPN: 1010040222) is a grid-connected hybrid inverter with an output power of 15 kW. It provides you with an uninterruptible power supply and switches seamlessly to island mode in the event of a power failure. Multiple devices can be operated in parallel, scaling the total system output to up to 150 kW. The integrated energy management system prioritizes your own consumption and automatically controls the charging and discharging power of the storage unit and consumers. The robust input architecture of this device allows you to feed in up to 200% of the PV power and reliably supply unbalanced three-phase loads of up to 5 kW per phase. With individual and smart operating modes, intuitive control, and full VPP compatibility, it is optimally designed for the future requirements of energy supply. With up to 28 A input current per MPPT, it is also designed for powerful, large-format solar modules and makes efficient use of their yield. Unlike the X3-HYB-G4-Pro, you can choose whether you want to use an LFP or a lead-acid battery.

How it works

The hybrid inverter is a powerful, three-phase device that efficiently converts the direct current generated by solar modules into grid-compliant alternating current and intelligently controls the energy flows between the photovoltaic system, battery storage, power grid, and consumers. Surplus solar energy is primarily used for self-consumption, then stored in a compatible battery, and only then fed into the public grid. When needed, for example at night or during periods of increased power consumption, the inverter reliably provides the stored energy. Optionally, it enables an uninterruptible emergency power supply in the event of a grid failure. With its high efficiency, flexible battery management, comprehensive protection functions, and modern communication interfaces, it offers an efficient and future-proof solution for the intelligent use and control of solar power in residential and commercial buildings.

200% PV oversizing, 110% AC power

Oversizing allows you to connect solar modules with up to twice the rated power of the inverter. This means you can achieve a higher electricity yield even when there is little sun. The increased AC power allows the inverter to deliver up to 110% of its rated power on the AC side for a short period of time, enabling you to make optimum use of power peaks.

VPP compatibility

This means that the device is prepared for integration into a virtual power plant (VPP). It digitally networks many decentralized energy sources, such as photovoltaic systems, battery storage systems, or flexible consumers, into a common, controllable network. This allows these systems to participate jointly in the energy market, provide balancing energy, or compensate for peak loads.

Different modes

In on-grid operation, the inverter offers you 6 different operating modes: self-consumption, feed-in priority, backup, peak shaving, TOU (time-of-use) and manual mode. This allows you to select the mode that best suits your energy needs and your everyday life. In the event of a power failure in the public grid, the inverter automatically switches to EPS mode (emergency power supply). This ensures that your connected consumers continue to be reliably supplied with energy.

Self-consumption – use your solar power for your household appliances first. Surplus energy charges the battery, and only then is electricity fed into the grid. This allows you to effectively save costs when electricity prices are high and feed-in tariffs are low.
Feed-in priority – ideal for high feed-in tariffs. Your PV system first supplies your consumers, and surplus electricity is fed into the grid and remunerated.
Backup – keeps the battery sufficiently charged at all times so that important devices continue to run reliably in the event of a power failure. This is particularly suitable for regions with frequent power failures.
Peak shaving - charges the battery when power consumption is low and releases energy when the load is high. This reduces peak loads and saves electricity costs.
TOU (Time-of-use) - is set via the SolaXCloud app or web interface. You can assign up to 10 time slots per day with different operating modes such as self-consumption, peak shaving, charging, or discharging. This allows you to flexibly adapt your system to your needs and electricity tariffs.
Manual mode - is intended exclusively for qualified personnel for maintenance and troubleshooting. Here, specific functions such as forced discharging, charging, or charging stop can be activated. After 6 hours, the system automatically switches back and exits manual mode.

Protection and safety

• Overvoltage/undervoltage protection
• AC overcurrent protection, AC short-circuit protection
• DC insulation protection, DC reverse polarity protection, DC feed monitoring
• Mains monitoring
• Regenerative power monitoring
• Fault current detection
• Overtemperature protection

Arc fault detection (AFCI) – optional

If your PV modules, connectors, or cables are incorrectly installed or damaged, arcing 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 offers you 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 power consumption and get the most out of your solar system. Your data is transmitted securely and reliably at all times. You can also conveniently download the app directly. Instructions for this can be found in the user manual.
