Overview

A 180W micro inverter is a compact device used in solar energy systems to convert direct current (DC) generated by a single solar panel into alternating current (AC) for home or grid use. Unlike string inverters, which handle multiple panels simultaneously, solar micro inverters are installed on each panel, allowing for more efficient energy production. These inverters are ideal for residential solar setups with smaller panels, where maximizing efficiency and monitoring capabilities is essential. They are also safer because they reduce the risk of high-voltage DC electricity running through the system.


Features:

  • Maximum power point tracking. High-performance maximum power point tracking (MPPT), reverse power transmission, increasing system efficiency..
  • Safe use. Traditional central or string inverters often have direct current voltages of hundreds or thousands of volts, which can easily catch fire and cannot be easily extinguished after a fire. The micro inverters are only a few tens of volts of direct current and are all connected in parallel, minimizing safety hazards.
  • Simple and convenient to use. The grid-connected inverter needs to be connected to the grid to use, the operation is simple and convenient for you to use.
  • Maximize power. Possess a small size and small capacity, commonly used in small solar energy systems.

120W micro inverter aluminium alloy shell

Aluminium Alloy Shell

It provides excellent heat dissipation, preventing overheating. Aluminum is lightweight, reducing the overall weight of the grid tie micro inverter and making installation easier. It offers strong corrosion resistance, enhancing durability in outdoor or harsh environments. Aluminum is non-magnetic, ensuring minimal interference with the inverter's electrical components. The material is cost-effective and recyclable, contributing to sustainability.
120W micro inverter terminal post

Terminal Post

In a photovoltaic micro inverter, the positive and negative terminals play crucial roles in managing the flow of electricity from solar panels to the grid. The positive terminal connects to the higher voltage side, while the negative terminal connects to the lower voltage side, completing the electrical circuit. This design optimizes energy transfer, reduces power loss, and enhances safety by ensuring proper grounding.
120W micro inverter IP65 protection

IP65 Waterproof Protection

IP65 waterproof protection in a 180W PV micro inverter ensures that it is dust-tight and protected against low-pressure water jets from any direction. This is crucial for outdoor installations as it safeguards the inverter from harsh weather conditions like rain, humidity, and dust. The protection enhances the inverter's durability and reliability, reducing the risk of damage and maintenance costs.

FAQ

How does micro inverter handle voltage fluctuations?

Micro inverters are designed to handle voltage fluctuations effectively, ensuring consistent energy output and protecting both the solar system and connected appliances. They manage voltage variations by performing Maximum Power Point Tracking (MPPT) and implementing various protective mechanisms.

  • Maximum Power Point Tracking (MPPT). MPPT micro inverters continuously adjust the voltage and current levels from each individual solar panel to maximize the power output, even under changing environmental conditions such as shading or temperature changes. This ensures the solar panel operates at its optimal power point, which helps mitigate the impact of voltage fluctuations from external sources.
  • Rapid Response. Because micro power inverters operate at the panel level, they respond quickly to voltage changes, ensuring minimal disruption in energy production.
