The GoodWe GW50K-SDT-C30 is a 50 kW three-phase on-grid inverter in the SDT G3 series. It is aimed at commercial rooftops, factories, warehouses, schools, hospitals and industrial sites that already have a three-phase grid. It is not a hybrid inverter, and it does not keep a site powered during a grid outage.
It has 4 MPPT trackers and 2 strings on each. Input current is 40 A. Short-circuit current is 52 A. Separate trackers can help with arrays that face different directions, but they do not guarantee a higher yield. Strings must stay inside 1,100 V, 140–1,000 V and these current limits. From 1,000 V to 1,100 V the inverter goes to standby.
Maximum efficiency is 98.7% and European efficiency is 98.0%. Grid frequency is 50/60 Hz (45–55 Hz / 55–65 Hz). Surge protection: Type II on AC and DC. The series cover states a maximum of 21 A per string and up to 180% PV oversizing. This model column does not print a separate maximum PV kilowatt, so 180% is not a string-design approval by itself.
Weight is 33 kg, size is 646 × 484 × 230 mm, and noise is 50 dB. Ingress protection is IP66. Smart fan cooling needs the clearances in the installation manual. The AC connector is OT/DT terminal, maximum 70 mm². The DC connector is MC4, 4–6 mm². Night-time self-consumption is less than 1 W.
SOLAR24 states a 5-year official warranty. Terms, purchase records, installation and any registration still apply. The datasheet does not print a warranty term. AFCI, rapid shutdown, PID recovery and night-time power supply are optional and are not included on every unit.

The selling price on this page is ৳280,000. The regular price is ৳320,000. The price is for the inverter. Panels, protection, mounting and installation are not included.
Rated active output is 50 kW and nominal apparent output is 50 kVA. On this datasheet the maximum AC active and apparent power are the same as those nominal ratings.
Yes. GW50K-SDT-C30 is a three-phase grid-tied string inverter in the GoodWe SDT G3 series. It is not a hybrid inverter and it is not an off-grid inverter.
GW50K-SDT-C30 has 4 MPPT trackers, with 2 strings per tracker. Do not use the tracker count from another SDT suffix.
Maximum input voltage is 1,100 V. When the input is between 1,000 V and 1,100 V the inverter enters standby, and it returns to normal operation when the voltage is back inside the MPPT working range.
The MPPT operating range is 140–1,000 V. Start-up voltage is 160 V and nominal input voltage is 600 V. The range at nominal power is in the user manual, not only on this datasheet.
GW50K-SDT-C30 lists 40 A maximum input current per MPPT and 52 A maximum short-circuit current per MPPT, across 4 trackers. The series cover also states a maximum of 21 A per string and up to 180% PV oversizing. The model table does not print a separate maximum PV kilowatt.
The datasheet lists 2 strings per MPPT. GW50K-SDT-C30 has 4 trackers, so the string plan has to match those trackers and the current limits above. Two strings on one tracker should be matched.
Maximum efficiency is 98.7% and European efficiency is 98.0%. These are datasheet conversion figures, not a promised annual yield.
Maximum output current is 75.7 A. Nominal output voltage can be 220/380 V, 230/400 V or 240/415 V, 3L/N/PE or 3L/PE. The output voltage range is 180–280 V according to the local standard.
The datasheet lists integrated PV string-current monitoring, insulation-resistance detection, residual-current monitoring, PV reverse-polarity protection, anti-islanding, AC overcurrent, AC short-circuit and AC overvoltage protection, plus an integrated DC switch.
Yes. The GW50K-SDT-C30 column lists Type II surge protection on both the DC side and the AC side. That is not the Type III configuration used by GW40K-SDT-C30.
Yes. GW50K-SDT-C30 returned a row on SREDA's three-phase Net Metering inverter search checked on 28 October 2026. Listed in SREDA's three-phase Net Metering inverter list. Each site still needs its own utility approval. This listing does not cover GW40K-SDT-C30 or GW50KS-MT.
No. GW50K-SDT-C30 is an on-grid inverter. This datasheet does not list a battery port or a backup output. Anti-islanding shuts down AC output when the grid is down.
Weight is 33 kg. Dimensions are 646 × 484 × 230 mm. Ingress protection is IP66. Noise emission in this column is 50 dB. Cooling is smart fan cooling.
The user interface is LED, an optional LCD, and WLAN plus the app. Communication on the reviewed sheet includes RS485, with Wi-Fi, LAN, Bluetooth or 4G listed as optional rather than all included. Protocols for this column: Modbus-RTU (SunSpec compliant) and Modbus-TCP.
SOLAR24 states a 5-year official warranty for GW50K-SDT-C30. It remains subject to the official terms, purchase records, installation requirements and any registration conditions. The reviewed datasheet does not print a warranty term, and this page does not add a 10-year warranty.
Match a three-phase grid, 4 MPPT string design, the 40 A input limits, 1,100 V standby behaviour, 50/60 Hz grid frequency, and Type II on AC and DC surge protection. Confirm SREDA and utility eligibility before relying on net metering. SOLAR24 currently lists 6 units in stock.
