A 110 kW string inverter with ten MPP trackers
The SUN2000-110KTL-M0 has 20 DC inputs on ten MPP trackers, a 1100 V maximum input voltage, an operating range of 200–1000 V and a full-load MPPT range of 540–800 V. The maximum short-circuit current is 40 A per MPPT and the maximum backfeed current to the PV array is 0 A.
AC output
The rated active power is 110 kW and the maximum apparent power 121 kVA. The rated output voltage is 220 V/380 V or 230 V/400 V, three-wire with an optional neutral, plus PE, at 50 or 60 Hz, with a power factor adjustable from 0.8 leading to 0.8 lagging and total harmonic distortion below 3% at rated power.
Protection
The inverter has an input DC switch, anti-islanding protection, output overcurrent and reverse-connection protection, PV string fault detection, DC and AC surge protection, insulation resistance detection and a residual current monitoring unit. The overvoltage category is PV II / AC III.
Installation and communication
The IP66, transformerless inverter weighs 90 kg, is cooled by intelligent air cooling and works from −25 to +60 °C at up to 4,000 m. It communicates over MBUS/RS485, with LED indicators and WLAN, Bluetooth or USB connections for the app.
