Solar & Storage Live Vietnam 2026: Xindun Power Delivers Reliable Off-Grid Solutions

The 10th Solar & Storage Live Vietnam concluded successfully at SKY EXPO Vietnam in Ho Chi Minh City from July 8th to 9th, 2026. As Southeast Asia's most influential solar energy storage industry event with over 200 exhibitors and 5,500+ visitors, this year's show brought together industry professionals from across the region. Guangdong Xindun Power Technology Co., Ltd. (Booth A2-H21) participated in the event, engaging in in-depth discussions on off-grid solar system solutions with industry professionals across Vietnam and the broader Southeast Asian market.

Vietnam is at a critical juncture in its energy transition. With a national target of over 30% renewable energy generation by 2030 and the October 2024 issuance of Decree 135 encouraging off-grid solar development, the country's residential and commercial off-grid PV market is entering a period of rapid growth. At the Solar & Storage Live 2026 opening forum, Vietnam's Ministry of Industry and Trade reaffirmed that off-grid and microgrid systems are key to solving electricity access in remote areas—confirming that Xindun's participation came at exactly the right time.

Show Floor Highlights

Throughout the two-day exhibition, the Xindun booth maintained a steady flow of visitors, with particularly strong crowds around the HDSX series three-phase inverter display area, where numerous customers stopped for in-depth consultations.

Technical engineers were kept busy addressing questions about product specifications, system configurations, and application scenarios. Many visitors showed strong interest in the customizable split-phase output feature and the high-power motor starting capability of the industrial frequency inverter, with several requesting on-the-spot configuration consultations for their specific projects.
One installer from Ho Chi Minh City, who had spent nearly 20 minutes discussing motor start-up challenges with the engineering team, summed up what many visitors were thinking:

"We've supplied many brands of inverters to our farming clients, and motor start-up has always been a headache. Your starting capability is truly impressive—this is exactly what we've been looking for."

Core Products: Industrial Frequency Inverter & Three-Phase Inverter

With nearly 20 years of manufacturing experience, Xindun Power has developed a comprehensive product line covering industrial frequency inverter, high-frequency, single-phase, three-phase, and split-phase output inverters—all designed to meet diverse off-grid solar system requirements. The following models received particular attention at the show:

1. Industrial Frequency Inverter – Designed for Heavy Motor Loads

Featuring a robust transformer design—toroidal for models up to 8kW and strip-wound for 8kW and above—Xindun's industrial frequency inverter delivers peak power up to three times its rated value, ensuring stable startup of air conditioners, motors, pumps, and other inductive loads. The series covers 700W to 40kW, with battery voltage options ranging from 12V to 384V.

While high-frequency inverters dominate the global market, industrial frequency inverters remain an important choice in Vietnam—where multi-generational households and small family businesses often require 10kW, 12kW, or higher single-phase output to run multiple heavy appliances simultaneously. Chinese-made power equipment also enjoys strong brand recognition in Vietnam, making Xindun's inverters a trusted fit for the local market.

2. HDSX Series Three-Phase Inverter (3.2kW-160kW) – The core power source for commercial and industrial off-grid applications
Designed for three-phase load scenarios such as factories and farms, the HDSX series three-phase inverter covers a full power range from 3.2kW to 160kW. A 3.2kW model can start a 3HP motor, while the 160kW model can start an 80HP motor, fully meeting industrial equipment startup requirements. The product supports customizable split-phase output to accommodate different national voltage standards and optional built-in MPPT controllers, along with RS485 and mobile app remote monitoring.
In addition, Xindun's hybrid solar inverters (HFP series) and ESS-Li series integrated solar power systems were also on display, covering applications from residential backup to small-scale commercial and industrial use.

Vietnam Local Case Study: Off-Grid Transformation at a Dong Nai Aquaculture Farm

A medium-sized tilapia farm in Dong Nai Province with 12 ponds required 24/7 operation of oxygen and water circulation pumps. The farm had long struggled with an unstable grid—frequent voltage drops and scheduled outages often exceeded 30 minutes, causing oxygen depletion and once resulting in the loss of over 2 tons of market-ready fish.
Frustrated by recurring losses, the farm owner turned to Xindun for a reliable off-grid solar system solution. After evaluating the site's power needs, Xindun designed and installed a 20kW off-grid solar system in early 2025, featuring the HDSX series three-phase inverter (20KVA/16kW model) as the core component:

Xindun HDSX three-phase inverter (16kW rated power, 48KVA peak) × 1 unit

Xindun MPPT solar controllers × 2 units

PV panel array: 33kWp

Lithium battery bank: 45kWh

Since commissioning, the system has delivered 95% power self-sufficiency, effectively solving the farm's outage-related losses. The owner estimates that savings on electricity and avoided losses will pay back the investment in about two years.
The case has since been promoted as a reference model within Xindun's Vietnam dealer network, particularly for agriculture, aquaculture, processing facilities, and small manufacturers. The farm owner also visited Xindun's booth at Solar & Storage Live Vietnam 2026 to share his experience—becoming one of the most compelling testimonials at the show.

Customer Voices: Real Feedback from the Show

Mr. Nguyen, a solar installer from Ho Chi Minh City
"Our company primarily works on commercial and industrial PV projects in the southern provinces. We've used several brands of off-grid inverters before, and a common issue is that they trip protection devices during motor startup. What impressed me most today is the customizable split-phase output of your industrial frequency inverter. Many factories in Vietnam import equipment from different countries with varying voltage requirements. If one inverter can handle it all, we won't need additional transformers. I'll gather parameters from a few clients and have you develop solutions for them."

Mr. A Qiang (pseudonym), manager of a coffee processing plant in Dong Nai Province
"Our factory is in the mountains, and the grid supply is frequently unstable. If the dryer stops, we lose an entire batch of beans. We've looked at some off-grid solar system options before but were always concerned about system stability. Then we saw your Dong Nai farm case—it's right in our neighboring province. If it works for the farm, it'll definitely work for our processing plant. We'll send our technical team to your Foshan factory in the coming days to finalize the system configuration."
