Overview

The 150W rating refers to the maximum power it can handle from a panel. This size is typically used with smaller solar panels or systems designed for low-power applications. Micro grid inverters offer advantages like easier system scaling, improved safety due to lower DC voltage, and enhanced energy monitoring for individual panels. Solar grid tie micro inverter converts the direct current (DC) generated by a single solar panel into alternating current (AC), which can be used by household appliances or fed into the electrical grid.

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.

Details:

Aluminium Alloy Shell

It provides excellent heat dissipation, preventing overheating. Aluminum is lightweight, reducing the overall weight of the solar 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.

Terminal Post

In a 150W grid tie 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.

IP65 Waterproof Protection

IP65 waterproof protection in a 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 do micro inverters handle shading on solar panels?

Micro inverters are highly effective at managing the impact of shading on solar panels. In traditional solar systems that use a central or string inverter, multiple panels are connected in series. If one panel is shaded, its reduced output affects the performance of the entire string, as the output is dictated by the weakest-performing panel. This limits the system's overall energy generation.

In contrast, this type of solar power inverter installed on each solar panel individually. They convert the direct current (DC) generated by each panel into alternating current (AC) at the panel level, independently from the rest of the system. This architecture allows each panel to operate at its optimal performance, even if others are shaded or partially obstructed. When shading occurs on one or more panels in a solar cell micro inverter system, only the affected panels experience a drop in output, while the others continue to produce energy at full capacity. This means that shading on one panel does not reduce the energy output of the entire system, leading to higher overall efficiency.
