The selling price is ৳550,000. The regular price is ৳610,000. The price is for the inverter only.
Rated output is 125 kW. Nominal apparent power is the same kilovolt-ampere figure. Maximum AC power is a separate datasheet value.
Yes. GW125K-GT is a three-phase grid-tied inverter. It is not a hybrid or off-grid inverter, and this datasheet does not list battery backup.
GW125K-GT has 10 MPPT trackers, with 2 strings per MPPT.
Maximum DC input voltage is 1,100 V. The MPPT operating range is 180–1,000 V, start-up is 200 V, and nominal input voltage on this sheet is 600 V.
Maximum input current is 42 A per MPPT. Maximum short-circuit current is 52.5 A per MPPT.
The datasheet lists 2 strings per MPPT. Strings on the same tracker should be matched, and the design must stay inside the voltage and current limits.
Maximum efficiency is 99.0%. European efficiency is 98.5%. That is a conversion figure, not a promised yearly yield.
The GW125K-GT column lists 137.5 kW maximum AC active power and 137.5 kVA maximum apparent power. VDE4105 is 134.9 kW / kVA. Chile and Brazil are limited to the 125 kW / 125 kVA nominal rating. Bangladesh is not named. Confirm the nameplate.
Maximum output current on this sheet is 199.4 A. Nominal voltage is 220/380 V or 230/400 V, 3L/N/PE or 3L/PE. The output voltage range is 304–460 V.
Integrated items include PV string-current monitoring, insulation detection, residual-current monitoring, reverse-polarity protection, anti-islanding, AC overcurrent, short-circuit and overvoltage protection, and a DC switch.
DC surge protection is Type II, with Type I + II optional. AC surge protection is Type II. AFCI, emergency power off, rapid shutdown, remote shutdown and PID recovery are optional.
Yes. GW125K-GT returned its own 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 utility approval.
No. This is an on-grid inverter. Anti-islanding shuts down AC output when the grid is down. It should not be bought as a battery inverter.
Weight is 88 kg. Dimensions are 930 × 650 × 300 mm. Ingress protection is IP66. Cooling is smart fan cooling. Night-time self-consumption is less than 2 W.
The interface is LED, optional LCD, and WLAN plus the app. Communication is RS485, with Wi-Fi + LAN, 4G or PLC optional. The protocol is Modbus-RTU, SunSpec compliant. Optional items are not included unless the supplied unit lists them.
SOLAR24 states a 5-year official warranty, subject to the applicable terms, purchase records, installation requirements and any registration. The reviewed datasheet does not print a warranty term.
Match three-phase voltage, 10 MPPT trackers, 42 A per MPPT, the 1,100 V limit, and the local maximum AC power. Confirm the exact SREDA row and utility approval before relying on net metering. SOLAR24 lists 3 units in stock.
