It's great to see our client Sungrow leading the way in technology innovation in the PV inverter space. 1500V products have been been discussed for some time now. Many module manufactures and central inverters are now able to run at 1500V but this is the first string inverter able to operate at 1500V. At 80kW it can be utilised at both commercial and utility scales which is a real plus point. We should be seeing plenty of other inverter manufacturers follow in Sungrow's footstep with their own versions. Due to the cost savings in BOS components and labour time this is stand out product which could help dramatically reduce PV installation costs going forward.
The SG80HV has a power output of 80KW rated at 1500VDC. With a 2.5MW PV power block design, DC side cabling costs can be reduced by 30%, according to the company. Sungrow’s patented five-level topology design enables SG80HV to lift the maximum efficiency up to over 99%, even at a 1500VDC voltage rating. Also, SG80HV is able to operate at 1.1 times overload in temperatures as high as 45 degrees centigrade. The SG80HV is capable of avoiding power losses caused by temperature de-rating with its class-leading cooling system. At a 1500VDC rating, the SG80HV is also able to reduce balance of system costs in addition to the high power generation yield it offers.
