Three-phase inverter SOFAR 17KTLX-G3, 17kW, 2 MPPT, WiFi, DC Switch, IP65 900.01600008-1

Three‑phase inverter 17 kW with two MPPTs and four DC inputs

The inverter has two independent MPPTs, each handling two DC inputs — a total of four ports. This allows you to connect up to four separate PV strings to a single inverter, each with its own cable and configuration. You do not have to combine panels into one series — you can separate them by orientation, tilt, or roof location, and each string will be optimized independently.

Rated power is 17 000 W, maximum AC power is 18 700 VA. The recommended maximum DC input power is 22 500 Wp, which enables the use of a slightly larger installation than the inverter itself. Each MPPT can handle up to 12 750 W DC, and the maximum input current per port is 26 A. Start‑up voltage is 160 V — the inverter starts quickly under low irradiance. MPPT operating range: 140 V to 1000 V. Full power is achieved in the 450–850 V range, covering most typical panel configurations.

Maximum efficiency: 98.75 %. European efficiency: 98.2 %. MPPT efficiency exceeds 99.9 % — almost all current from the panels is fed to the grid. Night‑time self‑consumption is below 0.5 W — it does not draw power in darkness.

The inverter includes a built‑in DC disconnect, allowing fast and safe shutdown of the system without disconnecting solar cables. Protection against reverse polarity, lack of grounding, and islanding operates automatically. It is equipped as standard with type II SPD surge protectors on both the DC and AC sides — no additional devices are required in the connection box.

Communication is based on Bluetooth and optional Wi‑Fi. You can monitor the system via a smartphone app — voltage and current of each string are displayed separately thanks to PV string error monitoring. Data are stored for 25 years — even after inverter replacement you retain the operating history of the previous unit.

The inverter operates on a 3/N/PE network voltage (220/380 VAC or 230/400 VAC). Network voltage range: 310 VAC to 480 VAC — compliant with local grid standards. Network frequency range: 40 Hz to 55 Hz and 54 Hz to 66 Hz — ensuring compatibility with various power systems.

The device is transformer‑less — reducing losses and increasing reliability. It has an IP65 protection rating — suitable for outdoor mounting, even in rain or dust, without the need for a shelter. Fan cooling maintains a stable temperature at maximum load, and a noise level below 40 dB ensures it does not disturb nearby buildings.

Dimensions: 513 × 425 × 189 mm. Weight: 22 kg. Installation is simple — a suitable wall or supporting structure is sufficient. Warranty: 10 years — confirmed by the manufacturer SOFAR.
