Overview

A 400W micro inverter is a compact device used in solar power systems to convert direct current (DC) generated by a single solar panel into alternating current (AC) for use in homes or feeding into the electrical grid. Unlike traditional string inverters, which connect to multiple panels, a solar micro inverter is installed on each panel. This design improves system efficiency by optimizing power output individually, ensuring that shading or damage to one panel doesn't significantly affect the overall performance. With a power rating of 400 watts, this type of PV micro inverter is suitable for small to medium-sized solar panels.

Features:

Use the Wifi communication mode.
Flexible installation, operation, and maintenance costs are low.
High-performance maximum power point tracking (MPPT), reverse power transmission, increasing system efficiency.
Various protections: isolated island protection, voltage protection, frequency protection, temperature protection, and current protection.

Details:

IP65 Waterproof

The shell of the 400-watt solar micro inverter is made of pure aluminum alloy with a low resistance copper core. It enhances safety by reducing the risk of electrical hazards, such as short circuits or corrosion due to moisture exposure. They protect against water ingress, preventing damage and ensuring the longevity of the system.

MPPT

MPPT enhances energy harvest, leading to higher overall system efficiency and increased electricity production. It also improves system reliability and longevity by reducing stress on components. Additionally, MPPT allows for more flexible system design, as each panel operates independently, making it easier to expand or modify installations without impacting the overall performance of the micro inverter 400W.

Streamlined Appearance

A streamlined appearance in micro inverters enhances aesthetic appeal, reduces size and weight for easier installation, and minimizes visual clutter, making it easier to integrate into tight or visually sensitive areas. This design often improves heat dissipation and durability, contributing to better overall performance of the solar grid tie micro inverter.

FAQ

How much space does the 400W micro inverter occupy?

A 400W micro inverter typically occupies a compact space, with dimensions generally ranging from 6 to 8 inches in length, 5 to 6 inches in width, and 1 to 2 inches in height. This makes it roughly the size of a small tablet or a large paperback book. The precise dimensions can vary slightly depending on the model.

The compact size of these micro grid inverters is designed to facilitate easy installation on the back of individual solar panels. Despite their small footprint, they are capable of efficiently converting the DC power generated by the solar panels into AC power for home or grid use.

In terms of weight, a 400W micro inverter typically weighs between 2 to 4 pounds, further adding to its ease of installation and handling. This combination of small size and lightweight design allows for greater flexibility in solar panel layout and placement, contributing to more streamlined and aesthetically pleasing solar installations.
