Chinese tech giant Huawei is using its smart photovoltaic offering to help Vietnamese households optimise the use of solar energy.

Huawei FusionSolar is a complete integrated system for residential solar energy.

The demand for a green and smart lifestyle has fuelled the Vietnam residential solar energy market and, subsequently, boosted the evolving needs for smart technology that is easier to install with safety standards and long-term operability that aims for higher self-consumption.

In 2020, Huawei delivered a total capacity of 4.3GW inverters in Vietnam. To develop the market further, Huawei has launched products for a complete integrated system for Vietnamese homeowners including the Sun 2000-2-5KTL-L1 and 2000-5-10KTL-M1 smart energy controllers, Luna 2000-5/10/15-S0 energy storage system (ESS), and Sun 2000-450W-P smart PV optimiser.

“With 30 years of expertise in digital information technology, we’ve incorporated many latest ICT technologies for optimal power generation, in building the foundation for solar to become the main energy source,” said Alen Zhang, sales director for Huawei FusionSolar in Vietnam. “Vietnam is a country with high solar power potential and we look forward to contributing towards greater adoption of solar energy among Vietnamese families with Huawei FusionSolar.”

When it comes to residential PV rooftop systems, residential installers are usually expected to provide homeowners with a robust, cost-effective, self-consumption system that remains efficient, flexible and easy to install, and comes with smart applications and reliable customer service. Huawei’s products have been developed to focus on delivering the benefits of optimal electricity cost, active safety and better experience.

PV energy generated by solar panels meets the electricity demand of homes in the daytime, and the surplus energy generated is used to charge batteries, which then discharge to meet peak electricity consumption at night. In this way, residential PV systems could achieve high self-consumption levels and this is where Huawei’s residential intelligent battery Smart String ESS could shine. Each battery pack has a built-in energy optimiser and supports independent charge and discharge management.

The AI-powered AFCI arc fault circuit interrupter proactively mitigates fire risk with rapid shutdown technologies achieving zero voltage on the rooftop and zero arc risks for dual-layer protection. Huawei has integrated the AI algorithm into AFCI, enabling accurate arc fault detection via a local neural network algorithm, speedy arc fault protection by inverter shutdown in 0.5s, which is below 2.5s stipulated in UL1699B, and pinpointing arc fault positioning, saving 80% onsite troubleshooting time and cost.

The FusionSolar inverter portfolio consists of single- and three-phase products, both compatible with its power optimiser.

The smart PV management system, available in web portal and mobile application, provides real-time energy flow and energy balance readings, and PV panel-level performance management.
