Sungrow New Generation Three Phase w/Wifi, DC Switch Built-in

The Gen-2 three-phase inverter line-up includes five variants – 5 kW, 7 kW, 10 kW, 15 kW and 20 kW. The range includes Arc Fault Circuit Interrupter (AFCI), real-time monitoring, a wide MPPT voltage range and a fully compliant built-in DC Switch which the manufacturers claim “enables easier installation and significant cost-savings”. Efficiency is reasonable with a rate of 97.40% and a maximum of 98.40% for the SG5.0RT unit ranging up to 98.10% with a maximum of 98.50% for the SG20RT model. It is worth noting the rates included on the data sheet are the European weighted efficiency rates.

The inverters’ 16 A input current and 25 A short circuit current should satisfy most residential installations while the start-up and MPPT voltage range (180 v – 1000 v) is notable with Sungrow indicating it will translate to higher system yield. Also worth noting is that it is possible to connect an uneven amount of strings to the MPPT trackers on the SG7.0RT and SG10RT models which will provide for flexibility. The THD (<3% at nominal power) and power factor (>0.99/0.8 leading 0.8 lagging) are just as they are for most other inverters.

The Gen-2 inverters come with a comprehensive list of protection mechanisms including an AFCI which Sungrow says substantially reduces the risk of electrical fires. They also include Smart IV Scan and real-time monitoring for quick fault location and troubleshooting, built-in Type II DC and AC surge protection, DC reverse connection protection, AC short-circuit protection and current leakage protection. The inverters weigh in from 18-21kg and measure 370mm wide, 480mm high and 195mm deep.

As far as warranty on the SG range, Sungrow offers coverage for defects in materials and workmanship for a period of 10 years from the date of installation, but no more than 11 years from the manufacturing date.
