During the forum, Huawei Digital Power introduced its FusionSolar portfolio, featuring intelligent inverters, energy storage systems (BESS), and power optimization modules. These solutions are positioned to help businesses streamline operational costs, boost efficiency, and gain greater control over power supply in a market environment marked by energy volatility.

Huawei emphasized that combining solar generation with smart storage ensures energy security, reduces reliance on the grid, and unlocks tangible economic benefits. These technologies also help Vietnamese enterprises meet increasingly stringent international environmental standards.

As the tier-1 partner of Huawei Digital Power in Vietnam, Hoa Nam Energy plays a pivotal role as the local bridge to global green tech. A company representative affirmed Hoa Nam’s commitment to walking alongside SMEs and C&I customers in the “greening” of production — strengthening competitiveness, optimizing investment returns, and expanding export potential.

Particularly spotlighted was the BESS (battery energy storage) solution, described as a strategic “key” for business resilience. Huawei’s storage systems boast a hybrid cooling technology and a round-trip efficiency (RTE) of up to 91.3%, putting them among the more advanced offerings currently available.

The collaboration signals more than a product launch. It underscores a shared ambition: to accelerate Vietnam’s transition toward cleaner power, and to help local enterprises align with global sustainability norms. For Hoa Nam Energy and Huawei Digital Power, this partnership is both a commercial move and a statement — that renewable energy is not just viable, but essential for the next wave of business growth in Vietnam.

Full series of Huawei comprehensive off-grid fuel removal power solution iPowerCube integrate power electronics technologies (such as watts, heat, and energy storage) and digital technologies (such as cloud, AI, and connection) to streamline energy flows and information flows. They fully use PV and energy storage to replace D.G.s, meeting inclusive power supply requirements of large, medium, and small-scale power consumption scenario. Compared with traditional solutions, iPowerCube solutions feature simpler reconstruction, faster deployment, and lower cost, making iPowerCube more applicable to areas with no or poor grid power.

Large-scale off-grid fuel removal solution iPowerCube-P:

Provides megawatt-level power supply capability and applies to industrial production scenarios such as mines, factories, and campuses, as well as livelihood scenarios such as large villages, islands, and resorts. Compared with the traditional AC coupling solution, the iPowerCube-P uses the DC coupling architecture, which reduces the number of energy conversion times, improves the efficiency, reduces the investment, and lowers the LCOE.

In Cameroon, over 25 MW PV plants and 60 MWh energy storage systems adopt the Huawei off-grid solution, powering 350 remote villages and benefiting about 50,000 households with approximate 300,000 residents.

Medium-scale off-grid fuel removal solution iPowerCube-S:

Provides 100 kW-level power supply capability and applies to livelihood scenarios such as small villages and islands as well as industrial production scenarios such as oil and gas wells, checkpoints, and transportation stations. Compared with the traditional split-type solution, Huawei iPowerCube-S adopts pre-integration and does not require distribution network reconstruction, which shortens the deployment period and reduces the investment.

In Zhuhai, Huawei iPowerCube-S solution is used to replace the original D.G. and supply power to the professional equipment and living facilities of the ship navigation station on the island. In this way, the D.G. is not required. The LCOE is reduced by 60%, the D.G.-related cost is cut by CNY220,000 each year, and 25 tons of carbon emissions are avoided.

Small-scale off-grid fuel removal solution iPowerCube-M:

Provides 10 kW-level power supply capability and applies to residential scenarios (such as apartments with no/poor mains power supply and rural villas) and industrial and commercial scenarios (such as shops, restaurants, and business outlets). Compared with the traditional solution with combined gasoline generator and batteries, Huawei iPowerCube-M solution features more flexible deployment, ultra-quiet design, higher reliability, and lower LCOE.

The post Vietnam – Developing solar power system with zero export solution appeared first on hoanamenergy.com.

Zero export is a Huawei’s solution that allows the solar power system to only generate power for consumption or charge into the power storage, without transmitting excess power to the national grid, also known as load tracking mode.

To apply zero export function, a power meter connected to smartlogger or inverter by RS485 communication wire is required to provide data about the power flow at the grid connection point. When there is a flow of power from the solar power system to the grid, the system will reduce the output power of the inverter to cut off the excess power.

However, not all power meters on the market are compatible and support zero export for Huawei devices, so customers should pay attention to choosing the following types of meters to be able to apply Huawei solution:

Compatible power meters for SmartLogger to apply zero export:

2-20KTL 1-phase and 3-phase inverters are only compatible with Huawei smart power sensor:  Huawei DDSU666-H – DTSU666-H 250A/50mA.

Compatible power meters for 30/36/40KTL-M3 inverter to apply zero export:

Compatible power meters for 50/60KTL-M0, 100KTL-M1 inverter to apply zero export:
