Huawei recently welcomed energy suppliers, partners and the media at its Johannesburg campus for the launch of its new range of commercial and industrial (C&I) inverters, supercharged by FusionSolar.
Xia Hesheng, President of Huawei Digital Power Sub-Saharan Africa Region, delivered the welcoming address which expanded on Huawei’s mission of building a high-quality solar industry in South Africa. “Even though loadshedding has abated, C&I customers are looking for cost-effective solutions for uninterrupted power systems.”
Herman Fourie, Senior Solutions Architect at Huawei Digital Power Sub-Saharan Africa, explained the technical specifications of the “punch above the rest” C&I inverters.
SUN2000-150K and SUN5000-150K inverters are highly efficient and reliable solar inverters designed to maximise power generation and ensure stability and performance. The inverters reach a peak efficiency rate of 98.8% to minimise energy loss during DC-to-AC power conversion for grid injection.
Features that promote scalable, smart energy use
String-level maximum power point tracking (MPPT) is an integrated feature enabling each solar string to operate at its optimal power point. “The average dynamic MPPT efficiency of the inverters is 99.866% while that of traditional inverters is only 99.84%,” said Fourie.
The FusionSolar platform allows businesses to monitor the inverters, review their performance data and diagnose any issues remotely. The inverters support multiple MPPT inputs that keep design options flexible and guarantee optimal utilisation of available PV resources, increasing yield by 1.5%.
Robust design saves energy costs
To prevent the fan in the inverters from being faulty due to dust accumulation, the software controls the fan to rotate reversely when the SUN2000-150K runs at low power.
The inverters work in a wide range of temperatures and they are equipped with robust features that protect against overvoltage, overcurrent, short circuits and other electrical faults.
A new era of active safety
The inverters have smart string-level disconnection that uses smart detection mechanisms with a fault detection algorithm. Should any component experience a short circuit, the direct current can be shut off in milliseconds. They are also equipped to intelligently detect ground faults and isolate them within 15 milliseconds during grid connection, reducing the chances of inverter failure by over 75%.
Huawei maintains long-term relationships and prioritises partners
Zhao Tianqi (Tom), Vice President of Huawei Digital Power South Africa, delivered a concluding presentation explaining how Huawei offers ongoing support and training on its new product offering. “Huawei takes the responsibility of training partners on how to get the best out of its products. We have developed in-house courses for pre-sales, sales and after-sales services for our partners.”
