Three-phase inverter SOFAR 12KTLX-G3, 12 kW, 2 MPPT, WLAN/LAN and RS485, DC disconnector 900.01600012-0

Three-phase Inverter 12 kW with Dual MPPT and WLAN/LAN Communication

This device is designed for on-grid photovoltaic systems where stability, efficiency, and easy grid integration are critical. It operates at 380/400 V AC, making it ideal for higher-power installations – both in residential settings and small commercial facilities. It does not require a transformer, which reduces losses and increases overall efficiency.

Two independent MPPT trackers allow connection of two separate PV array sections – for example, with different tilt angles, orientations, or levels of shading – without power loss. Each tracker supports a maximum PV power of 7500 W, and the operating voltage range from 140 to 1000 V enables flexible panel selection, even under low-temperature or partial-shading conditions.

Maximum efficiency reaches up to 98.2%, while European efficiency reaches up to 98%. This means that virtually every additional watt generated by the panels is fed into the grid rather than lost during conversion. The power factor can be adjusted from -0.8 to +0.8, allowing adaptation to grid operator requirements.

The device has an IP65 protection rating – it is fully protected against dust and water. It can be mounted outdoors without an enclosure, even in rain or strong wind. The operating temperature range extends from -30°C to +60°C, making it suitable for various climates.

An integrated DC switch allows safe disconnection of the DC circuit during maintenance or emergencies – no additional external disconnect switch is required. Protection also includes surge protection (Type II SPD on both input and output), reverse polarity protection, ground fault detection, and anti-islanding protection.

Communication is supported via WLAN, LAN, and RS485 – the unit can be connected directly to a router or local network. Monitoring is available through a mobile app or web platform, displaying real-time power output, daily/monthly energy production, and system errors. No additional communication modules are needed – everything works "out of the box".

Cooling is active – a fan ensures stable operation even under prolonged high-temperature load. Noise levels are low – below 40 dB – so it does not disturb the surroundings when installed near a home.

Weight is 29 kg – light enough for two people to handle during wall or roof mounting. Dimensions (430 x 385 x 182 mm) allow installation in tight spaces.

Compliant with the latest European standards: VDE-AR-N 4105, CEI 0-21, EN 50549, and IEC 62109-1/2. It supports a grid frequency of 50 Hz (for Poland) and a grid voltage range from 310 to 480 V AC – adapted to local conditions.

No external communication module or DC disconnect switch is required – everything is already built-in. This is the solution for those who want full control over their system without unnecessary complications.
