Description
There are five different models in the Gen-2 three-phase inverter lineup: 5 kW, 7 kW, 10 kW, 15 kW, and 20 kW. The line comprises 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 acceptable, with the SG5.0RT unit having a rate of 97.40% and a maximum of 98.40% and the SG20RT model having a rate of up to 98.10% and a maximum of 98.50%. The rates listed on the data sheet are the European weighted efficiency rates, it is important to note.
The 16 A input current and 25 A short circuit current of the inverters should be sufficient for the majority of home installations, and Sungrow notes that the start-up and MPPT voltage range (180 v – 1000 v) is noteworthy since it will result in a greater system yield. It’s also important to note that the SG7.0RT and SG10RT models’ MPPT trackers allow connections of uneven numbers of strings, allowing additional versatility. The power factor (>0.99/0.8 leading, 0.8 lagging) and THD (3% at nominal power) are same to those of the majority of comparable inverters.
A long range of safety features, including an AFCI, are included with the Gen-2 inverters, according to Sungrow, significantly lowering the risk of electrical fires. They also have built-in Type II DC and AC surge protection, DC reverse connection prevention, AC short-circuit protection, and current leakage protection, as well as Smart IV Scan and real-time monitoring for quick fault discovery and troubleshooting. The inverters are 370mm wide, 480mm high, and 195mm deep. They weigh between 18 and 21 kilogramme.
