• Systems with high self-consumption, smart homes, or critical loads
• Households with wall boxes, heat pumps, or variable load profiles

Hybrid power for maximum independence

The SolaX X1-HYBRID G4 combines solar power generation with efficient battery storage for maximum independence from the power grid. Surpluses from the PV system are stored and released again when needed. With a charging/discharging efficiency of up to 97%, every ray of sunshine generated is used optimally. Thanks to its fast CT-controlled response time of just 0.3 seconds, it can compensate for load and feed-in changes with virtually no delay – ideal for households with variable consumers.

EPS emergency power supply with peak performance

In the event of a power failure, the inverter automatically switches to EPS mode in less than 10 ms and continues to reliably supply defined consumers. For particularly critical loads, the EPS output delivers up to 7.4 kW (200%) for 10 seconds – ideal for household appliances, routers, emergency lighting, or server technology. In combination with intelligent load management, the system automatically prioritizes important consumers in order to make optimal use of the available energy.

200% PV oversizing – more modules, more power

The G4 series allows the DC input to be loaded with up to 200% of the AC rated power. This means you can operate 7.4 kWp PV power on a 3.7 kW inverter, for example. This increases yields in low irradiation conditions and maximizes self-consumption – ideal for east-west roofs or winter operation.

Smart operation with cloud, app, and VPP

you can connect the inverter directly to the SolaX Cloud via Wi-Fi or LAN. The free app enables real-time monitoring, configuration, and remote maintenance. The device is also VPP-compatible (Virtual Power Plant) and can become part of a virtual power plant in supported regions. The integrated load management system can also control external consumers such as wall boxes or heat pumps as needed, thus perfectly balancing generation, storage, and consumption.

Robust, low-maintenance, and quiet

Thanks to passive cooling, the X1-HYBRID-D G4 operates almost silently and is ideal for residential areas. The IP65-certified aluminum housing provides reliable protection against dust and water, even when mounted outdoors. Weighing 24 kg, installation is quick and easy.
