Overview
The KSTAR G70KT is the 70 kW version of the three-phase G series and the first model with three strings per MPPT. Four MPPTs take three strings each, 12 strings in total, with 45 A input current and 60 A short-circuit current per MPPT. The input withstands up to 1100 V DC at a nominal voltage of 650 V; the MPPT range runs from 200 to 1000 V and KSTAR states a DC/AC ratio of up to 1.5.
Read the full description
The output is 230/400 V (3P+N+PE) at 50/60 Hz (±5 Hz): 70000 W nominal and up to 77000 VA. Maximum efficiency 98.6 percent, European efficiency 98.3 percent. For power limitation or zero export, KSTAR names the SPC01 Power Control Box, which works with KSTAR three-phase grid-tied inverters from 3 to 125 kW via RS-485.
The transformerless enclosure measures 548 × 540 × 289 mm; IP66, fan cooling, operation from -25 to +60 °C up to 4000 m altitude. A DC switch, anti-islanding, output overcurrent and reverse-polarity protection, residual current monitoring, AC short-circuit protection and type II surge protection on DC and AC are built in; string fault detection is optional. The AC connection uses OT ring terminals; communication via RS-485 and Wi-Fi, operation via LCD. KSTAR gives a 5-year limited manufacturer warranty on this on-grid inverter.
