Where to Install the PV Inverter?

As the power conversion equipment of PV power station, inverter occupies a pivotal position in the whole power station. Solar inverter is a power electronic device that converts the low-voltage DC power generated by the modules into AC power, which is connected to the load or integrated into the power grid, and is the core device in the photovoltaic system. Grid-connected inverters have the following main functions: converting DC power generated by PV modules into AC power; dynamically finding and utilizing the maximum power point (MPP) to maximize the available power through a maximum power tracker; recording operating data; and providing current, voltage and local grid-related protection.

Where to install the PV inverter?

Common installation solutions for ground-based distributed projects: can be installed under a string of modules nearby, using fixed bracket mounting or using clamp mounting to fix the equipment directly on the columns. This option requires attention to the strength of the brackets and holding posts and the height of the PV inverter above the ground to prevent placing it too low to flood the equipment with rainwater during heavy rainstorms.

1. Large industrial and commercial plant installation program: large industrial and commercial roofs are generally open roof, no roof and walls. Photovoltaic inverters can be hung in the place, out of the consideration of reducing the cost of cables, generally need to make their own mounting bracket, and the inverter will be hung on the homemade bracket. The bracket needs to consider the inverter load-bearing and fixing form as well as the ability to resist typhoons in coastal areas.

2. Common household distributed project rooftop power plant installation program: photovoltaic inverter as far as possible to be installed in the south wall, its panel to face the north, less sunshine. The machine should be installed at a suitable height from the ground to observe and read the LED display. For outdoor installation, a rain and sun canopy should be installed on top of the inverter to avoid direct sunlight and rain soaking.

3. Microinverter system: Microinverters can be installed directly on the bracket below the component, or integrated with the component to realize modular design to achieve plug-and-play. Micro inverters are small, do not occupy the installation space independently. Distributed installation is easy to configure, and can fully utilize the space and adapt to the application of different installation directions and angles.

How long is the design life of an inverter?

Generally speaking, the design life of the inverter determines the service life of the PV system. According to statistics, the design life of a conventional inverter is about 10 years, and the inverter needs to be considered for replacement once in the 20-year service life of the power plant. ADAYO micro-inverters have a design life of 20 years, which is the same as that of the modules, so there is no need for a second investment during the 20-year life cycle of the PV power plant, which reduces the investment risk.
