Overview
At 40 kW, the KSTAR KSG-40KT-M1 is the largest model of the three-phase KSG series. Three MPPTs take two strings each, six strings in total, with 30 A input 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.

The output is 230/400 V (3P+N+PE) at 50/60 Hz (±5 Hz): 40000 W nominal, up to 44000 VA and 63.8 A maximum output current. Maximum efficiency 98.7 percent, European efficiency 98.4 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 380 × 483 × 227 mm and weighs 32.5 kg; 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, insulation detection and AC short-circuit protection are built in; string fault detection is optional, surge protection DC type II and AC type III (type II optional). Communication via RS-485, Wi-Fi and Ethernet, operation via LCD. KSTAR gives a 5-year limited manufacturer warranty on this on-grid inverter.
