Chinese technology giant Huawei is targeting the Australian solar installation market with three-phase smart inverters that use artificial intelligence (AI) and self-learning algorithms to improve safety.
The SUN2000-5-20KTL-M0 smart PV inverter could fuel growth in the household, industrial and commercial segments with the product designed to deliver safety and reliability, even in the harshest of Australian conditions.
The technology provides increased safety, thanks to the arc fault circuit interrupter (AFCI), which uses AI technology to detect any signs of over-heating that can cause fires.
The AFCI can disconnect the circuit within two seconds of detecting a problem and, using AI, it can develop self-learning algorithms that enable more accurate arc-detection with fewer false alarms, thus improving the security of PV plants.
The AI technology also enables a one-click remote health check of all strings and accurate identification of 14 types of PV string faults, with diagnosis reports available in ten minutes.
This means operation and maintenance personnel no longer need to climb rooftops to gain access to solar equipment to troubleshoot panel faults; it can be done remotely which reduces time and labour costs.
Huawei recognises the need for inverters to deliver reliability and has used its experience in the industry to deliver a failure rate of less than 0.5%. It has achieved this by leveraging technologies such as big data, IoT and AI to improve the products.
The arrival of this inverter technology comes as the local market added some 156MW of small-scale rooftop solar capacity in June, taking the total yearly power addition to nearly 2GW across the country.
Huawei integrates digital information technologies such as AI, IoT, big data and cloud computing, with PV technology, to promote smart PV products for utility-scale, commercial and residential scenarios. Based on reports released by global consultancy IHS Markit, Huawei was ranked top globally in inverter shipment for four consecutive years, from 2015 to 2018.
