Micro-inverter Photovoltaic Potting Adhesive

Micro-inverter potting adhesive is a fluid silicone thermal conductive composite material made from silicone resin as the base, filled with thermal conductive fillers, and processed through specialized techniques. It features excellent thermal conductivity, electrical insulation, weather resistance, temperature resistance, moisture resistance, and anti-aging properties.

Low viscosity, good fluidity

Resistant to cold and hot shock, high temperature aging, self-adhesive, moisture-proof and waterproof

Can maintain stable physical and mechanical properties for a long time at -50℃~200℃

JISDI Micro-inverter Photovoltaic Potting Adhesive combines the protective advantages of silicone potting materials with thermal conductive filler technology. It is developed to provide stable encapsulation for photovoltaic inverters, micro-inverters, PCB assemblies, power modules, and other electronic components that operate under heat, humidity, and electrical stress.

• Thermal conductive protection: helps transfer heat from electronic components, PCB boards, inductors, and power devices to the surrounding housing or heat dissipation path, supporting stable operation of photovoltaic inverter modules.

• Electrical insulation performance: forms an insulating protective layer after curing, helping reduce the risk of electrical leakage, short circuits, and unstable operation in dense electronic assemblies.

• Moisture and environmental resistance: helps protect internal components from humidity, dust, and outdoor environmental exposure, which is important for solar inverter and micro-inverter applications.

• Good flowability for potting: the material can flow into gaps around electronic parts before curing, making it suitable for complex PCB layouts, compact module structures, and housing cavities.

• Silicone-based flexibility: after curing, the material can help reduce stress caused by temperature changes, vibration, and component expansion or contraction.

• Thermal shock and aging resistance: suitable for electronic modules that may experience long-term operation, temperature cycling, and demanding environmental conditions.

• Component fixation and mechanical protection: helps stabilize electronic parts inside the housing and reduce damage caused by vibration, handling, and impact during use or transportation.

• Suitable for photovoltaic electronics: designed for applications such as micro-inverters, solar inverter modules, power supply units, PCB boards, controllers, and related electronic assemblies.

• Process-friendly potting material: can be evaluated for manual dispensing, semi-automatic dispensing, or automated potting processes according to production requirements and selected product model.

When selecting a solar inverter potting compound, buyers should consider thermal conductivity, viscosity, curing conditions, insulation requirements, adhesion to the housing, production process, and long-term environmental reliability. JIADI can provide product selection support according to the customer’s inverter structure, operating environment, potting thickness, and production process.
