Enhancing PV System Safety with Class A Fire Resistance

Fire incidents present a significant commercial risk in the PV market, particularly in C&I and residential installations, accounting for approximately 50% of total commercial loss claims. Lola Li, General Manager Italy and France DG business at LONGi, states that the company addresses this by introducing its fire-resistant modules. LONGi's Class A fire resistance modules actively prevent ignition via BC contact technology for hotspot management and optimized junction box soldering to mitigate DC connection arcing. To prevent fire spread, the modules incorporate flame retardant encapsulation and fire-resistant glasses, developed through collaboration with top-tier suppliers.

HiMo 1 Pro: Advanced Safety for C&I BESS Applications

LONGi's HiMo 1 Pro Battery Energy Storage System for the C&I segment prioritizes long-term operational safety and reliability. According to Lola Li, this is achieved through a multi-layered approach involving sourcing key electrical components and cells exclusively from top-tier suppliers. All subsystems, including EMS, BMS, TMS, PCS, and the patented ICCS hardware, are developed and manufactured in-house for seamless synergy. This integration, combined with automotive-level production standards, has contributed to over 12 GWh delivered with zero thermal runaway incidents, and enables pre-alerts up to six months in advance.

"Our core value proposition is the safety. So we not only care how the system can be operated successfully, the more we care is how long the system can successfully and safely operate throughout the life cycle." Li · LONGi · 02:52

Flexible and Scalable BESS Solutions for Diverse C&I Needs

The HiMo 1 Pro BESS offers flexibility for various application scenarios through its support for both AC and DC cabinets. LONGi has designed the AC cabinets to connect with up to 11 slave cabinets, allowing for system expansion. Additionally, the AC cabinets can be connected in parallel, facilitating easy scaling to maximum capacities. This design, as presented by Lola Li, provides the market with solutions offering maximum flexibility for diverse C&I energy storage requirements.

Hello everyone, welcome to Longi Solar booth at Intersolar 2026. My name is Lola Li, I'm the general manager of Longi Italy and France DG business. And today, I would like to bring you to our new star products that we're launching during Intersolar. So first of all, let's look at the product that I'm showing right now. It's an anti-- It's fire resistance modules. As we all know that right now the fire incidence is a hot topic in the market, especially when we have more and more installations in C&I segment and also residential segment more closer to our communities. And if you know that according to the insurance claims, even though the fire incidents only represents of 8% of the total claims, however, it actually brings a lot commercial compensations in terms of the commercial loss. It represents roughly 50% of the total commercial loss. And that is why Longi, as a reliable module producer, we would like to bring a solution to the market. And this is the world first Class A fire resistance module. And how are we able to achieve the fire resistance? Actually, from a design perspective, we believe it actually consists of two parts. One is preventing the ignitions. That means we are having our BC contact, back contact technology that manage the hotspots and optimize the risks. And secondly, most of the ignitions are generated by the DC connection arcing. And with our optimizations in the junction box soldering technologies, we are able to reduce the risks. So secondly, we believe we have to prevent from the spreading. And in order to prevent the spreading, we believe there are flames and also the burning drips. And we have collaborated with our top tier suppliers in order to create and bring to the market the very first flame retardant encapsulation, and also the fire-resistant glasses. So in this way, we're able to convert from passive protections into active preventions. So here we come to our C&I best solution. This year we are also launching our BESS into the market for C&I segment, and this is our HiMo 1 Pro. Our core value proposition is the safety. So we not only care how the system can be operated successfully, the more we care is how long the system can successfully and safely operate throughout the life cycle, and how are we able to achieve that. Actually, we have three different layers of initiatives that we want to bring to industry. First one, we are collaborating with the top tier suppliers. All the cells and also the key electrical components that we only exclusively source from the top tier suppliers. And second one, we have everything, all the subsystem developed and also manufactured in-house. We have our own EMS system, BMS, TMS, PCS, as well as our ICCS. So all the in-house development can secure a consistency in terms of the interactions and also seamless synergy. And the third of all, we're having these combinations of hardware and our software. What does it mean? We have our in-house developed EMS combined with our ICCS, and our ICCS is a patent product hardware. And altogether, we can help to deliver a pre-alert from up to three to six months in prior. And our ICCS, this is a sample of our ICCS. As you can see, we have all the sensors and valves integrated into the plate, which can help to collect the data at a very fast speed and also for the faster data transactions. So that is how we're able to deliver the pre-alert of three to six months. So over the past production records, we have already delivered 12 gigawatt hours throughout the past years and zero thermal running waste. And in addition, we are adopting the automotive level production standard. What does it mean? So we not only care about the design of the product, but also we care about the reliability during the entire production processes. If you take a look inside into the product, you will see how sophisticated all the wavings and also cables are connected. And in terms of the application scenarios, we have AC cabinets also embedded with the storage inside and also the DC cabinet. And with our AC cabinets, we are able to connect up to 11 slave cabinets with it. And meanwhile, we can also achieve, help to deliver the AC cabinets in connections in parallel. That is to say, we can easily expand to maximum capacities. So that is how we are providing to the market a solution with the maximum flexibilities and application scenarios. Thank you so much, and if you have more questions, welcome to join to our booth or check our website eu.longi.com. Thank you. Longi.

Frequently asked questions

According to Lola Li, these modules directly address the risk of fire incidents in PV installations, particularly in C&I and residential segments. Such incidents, while 8% of claims, contribute to 50% of commercial losses.

LONGi achieves Class A fire resistance by preventing both ignition and spread. This involves BC contact technology to manage hotspots, optimized junction box soldering to reduce arcing, and flame retardant encapsulation with fire-resistant glasses.

Lola Li states that the core value proposition of the HiMo 1 Pro BESS is long-term operational safety and reliability throughout the system’s entire lifecycle. It aims to ensure consistent, safe performance.

The HiMo 1 Pro integrates an in-house developed, patented ICCS (Intelligent Cloud Control System) hardware with sensors and valves. This system enables the delivery of pre-alerts for potential issues up to three to six months in advance.

Reliability is secured by sourcing top-tier cells and components, developing all subsystems in-house for synergy, and adhering to automotive-level production standards. This approach has resulted in zero thermal runaway incidents across 12 GWh of past production.

The HiMo 1 Pro offers high flexibility, supporting both AC and DC cabinet configurations. AC cabinets can connect up to 11 slave cabinets, and parallel connections allow for easy expansion to meet maximum capacity requirements.
