At the Electricity Transformation Canada (ETC) 2026 exhibition in Toronto, Hoymiles officially introduced its HiOne all-in-one residential energy storage system to the Canadian market. Alongside this residential debut, the company showcased its HoyUltra 261A commercial and industrial (C&I) energy storage system for the first time in North America. This dual-pronged product launch highlights the company's strategic focus on addressing the diverse energy needs of Canadian households and businesses as they navigate grid reliability challenges and rising electricity costs.

The HiOne Residential System: Streamlined Home Energy Management

As Canadian homeowners seek greater energy independence, reliable backup power, and enhanced control over their electricity expenses, the HiOne system offers an integrated approach to residential energy management. The system combines an inverter, a battery system, and an energy management system (EMS) into a single, unified unit. This integrated design addresses common consumer pain points associated with complex, multi-component residential solar setups.

Rapid Installation and Optimized Solar Generation

One of the primary design features of the HiOne system is its streamlined, home-friendly physical architecture. According to the company, the integrated unit can be installed in as little as 15 minutes, significantly reducing labor time and installation costs for local contractors.

To maximize solar energy capture across diverse residential rooftops, the HiOne system is equipped with four MPPTs (Maximum Power Point Trackers) and supports a maximum input current of 20A. This configuration allows the system to optimize solar generation across different roof orientations and varying shading conditions, ensuring that households can generate power even under suboptimal environmental conditions. Additionally, the system features seamless backup switching, which helps keep essential household loads powered during unexpected grid outages.

Rigorous Safety Standards and Thermal Runaway Prevention

Safety remains a critical consideration for indoor and outdoor residential battery installations. The HiOne system features a comprehensive safety design certified by TÜV and VDE. Furthermore, the system has achieved compliance with the UL 9540A safety standard.

During system-level thermal runaway propagation testing, the thermal runaway remained strictly confined to the triggered cell. The test demonstrated no propagation of thermal runaway throughout the battery module and no fire was observed in the system. This performance under testing conditions reinforces the system's safety credentials for residential applications, particularly in dense urban or suburban environments.

Scaling Up: The HoyUltra 261A for Commercial and Industrial Applications

In addition to residential solutions, Hoymiles introduced the HoyUltra 261A to the North American market to address the commercial and industrial sector. The HoyUltra 261A integrates battery storage, power conversion, liquid cooling, and intelligent controls into a single commercial-grade system.

Adaptive Liquid Cooling for Extreme Canadian Winters

Operating energy storage systems in Canada requires hardware capable of enduring extreme seasonal temperature variations. The HoyUltra 261A features an adaptive liquid-cooling system designed to optimize thermal management. The cooling system dynamically adjusts its operation based on:

  • Ambient temperature
  • Power output
  • Overall system status

This adaptive thermal management is particularly crucial for maintaining battery health and efficiency during Canada's cold winters and warm summers.

Intelligent Energy Management and Peak Shaving

For businesses looking to manage operational costs, the HoyUltra 261A utilizes intelligent charge and discharge scheduling. This software-driven approach helps commercial users optimize their energy consumption profiles. By employing strategies such as peak shaving and off-peak charging, businesses can reduce their reliance on the grid during high-tariff periods and lower their overall electricity expenses where such utility structures are applicable.

Expanding the Solar Ecosystem: Microinverter Solutions

Beyond energy storage, Hoymiles displayed its established solar microinverter solutions at the Toronto event. These include the HMS single-phase series and the HMT three-phase series.

  • The HMS and HMT series feature module-level MPPT to ensure optimized solar generation at the individual panel level.
  • The microinverters utilize a low-voltage DC architecture, which enhances overall system safety by minimizing high-voltage DC risks on residential and commercial rooftops.

Strategic Implications for the North American Energy Market

The introduction of these residential and commercial systems at ETC 2026 marks a significant step in Hoymiles' expansion strategy within North America. By connecting with local industry partners, distributors, and installers, the company aims to build a robust support and service network across Canada. As the region continues its transition toward decentralized, renewable energy resources, the availability of integrated storage solutions like the HiOne and HoyUltra 261A will play a role in supporting grid resilience and clean energy adoption for both homes and businesses.
