Until recently, utility scale solar power systems have been designed with the largest capacity central inverters available. With the introduction of string inverters, systems with capacities in the range of 1MW to 10MW have been successfully designed and installed using three-phase, 1000VDC string inverters with capacities in the 30kW to 60kW range.
Sungrow’s introduction of the SG125HV, a 1500VDC string inverter with a 125kW capacity has made even the largest utility scale solar power systems within the range of the string inverter system architects.
