LONQ-HT3M: A Reliable "Guardian" for Outdoor Photovoltaic Applications

2025-09-15

With the vigorous development of the photovoltaic industry, the stable and safe operation of outdoor photovoltaic systems cannot be separated from core components with excellent performance. The newly launched LONQ-HT3M photovoltaic product of our company has become an ideal choice for outdoor photovoltaic scenarios with its all-round advantages.

1. IP65 Protective Shell, Building a Solid Outdoor Safety Barrier

The LONQ-HT3M adopts an IP65 - rated protective shell. This standard means that it can completely resist dust intrusion and can withstand low-pressure water spraying from any direction without damaging internal components. Whether it is a desert photovoltaic power station with sand and dust or a coastal photovoltaic project site with rainy and humid conditions, it can easily cope with the challenges of harsh environments.


What's more worth mentioning is that the shell has waterproof and flame-retardant properties. The waterproof performance ensures that the internal circuit of the product can be protected from water vapor erosion in rainy and humid environments, avoiding short circuits and failures caused by moisture; the flame-retardant performance reduces the risk of fire from the source. Even in the event of accidental high temperature or open flame, it can effectively inhibit the spread of fire, adding another layer of protection for the safe operation of outdoor photovoltaic systems, allowing users to deploy it in various outdoor scenarios without any worries.


2. LQBQ-63Z 2P Circuit Breaker, Flexibly Adapting to Diverse Needs

The product is equipped with an LQBQ-63Z 2P circuit breaker inside, which can control and protect the live wire and neutral wire at the same time. When abnormal conditions such as overload or short circuit occur in the circuit, the circuit breaker can quickly cut off the circuit to avoid the expansion of the fault, effectively protecting system equipment such as photovoltaic modules and inverters from damage, and building a solid safety line for the stable operation of the entire photovoltaic system.


Moreover, the current specification of the circuit breaker supports flexible selection from 6A to 63A, and can accurately match current parameters according to the power requirements of different photovoltaic systems (such as small household photovoltaic systems, medium-sized industrial and commercial photovoltaic power stations, etc.), meeting diverse photovoltaic application scenarios and providing adaptive guarantee for the efficient and safe operation of the system.

3. MC-4 Connector, Plug-and-Play to Simplify Installation

To make installation and use more convenient, the LONQ-HT3M is equipped with an MC-4 connector. As a standard connector widely used in the photovoltaic field, MC-4 not only has excellent electrical and mechanical properties, but its plug-and-play design is also a major highlight - installers do not need to perform complicated wiring, and can complete the quick connection between the product and photovoltaic components and other equipment with just simple plugging and unplugging.


This design greatly simplifies the installation process. Whether it is a professional photovoltaic installation team or a photovoltaic enthusiast with a certain ability to operate, they can easily get started, saving manpower and time costs, and helping the photovoltaic system to be put into use faster.

Conclusion

The LONQ-HT3M integrates advantages such as an IP65 waterproof and flame-retardant shell, a flexibly selected LQBQ-63Z 2P circuit breaker, and a plug-and-play MC-4 connector. It not only meets the high requirements for product protection and safety in complex outdoor environments, but also takes into account the convenience of installation and use. It is a reliable "guardian" for outdoor deployment of photovoltaic systems, providing strong support for users to achieve a more efficient and safer application experience in the photovoltaic field.
