Huawei featured its utility-scale solar inverter at the Intersolar show in San Francisco last week. The company’s 45KTL inverter comes in a 1,500-V model in 500 kVA, and 1,000 V in 27.5 kVA, 33 kVA, 36.6 kVA, 40 kVA and 44 kVA. Huawei says the inverter is smart, efficient, safe and reliable.
The inverter features four MPPTs for flexibility in different layouts. It has eight strings for intelligent monitoring and fast trouble-shooting. Power line communications and smart I-V curve diagnosis are supported.
The inverter has a max efficiency of up to 98.9% and a CEC efficiency up to 98.5%.
The inverter’s DC AFCI is compliant to UL 1699B Type I with Type II surge arresters for both DC and AC. It also has residual current detection (RCD) protection.
The inverter is made reliable with a fuse-free design and a NEMA Type 4X protection rating. Natural cooling technology with no external fans also adds to its reliability.
Huawei believes string inverters are key to improving project economics. Its regional headquarters is in the heart of Silicon Valley with a team of nearly 50 professionals available to support projects, from distributed generation to large megawatt-systems.
