Best PV Inverters For Solar Panels

What is a PV inverter?

Anyone can use photovoltaic solar panels to power an off-grid local electrical network or to feed electricity into a commercial electrical grid via an inverter that transforms the DC output to an AC frequency suitable for grid supply.

It is an essential part of the photovoltaic system’s BOS because it allows for the usage of traditional AC equipment. The maximum power point tracking and anti-islanding protection of solar power converters have been designed explicitly with solar arrays.

How Does A Solar Inverter Work?

A solar inverter is an essential component of any solar photovoltaic (PV) system used to power appliances that operate on alternating current (AC).

Domestic appliances and most industrial gear operate on alternating current (AC), which a solar converter converts from solar panels’ direct current (DC). IGBTs (integrated gate bipolar transistors) convert the direct current to pulses, which are then shaped into a sine wave by additional circuits.

Types of Inverters For Solar Panels

Solar inverters are offered in three configurations for homeowners. Power optimizers with an inverter are one form of string (or central) inverter, whereas microinverters are another.

Each type of solar inverter offers several distinct advantages and disadvantages. It’s critical to understand these distinctions and the advantages and disadvantages of each type of solar inverter before deciding which is best for your solar panel system.

Micro-inverters (Grid-tie)

Microinverters are the most recent generation of solar pv inverters, and they work by converting DC from the back of each solar panel straight into AC electricity. There is no need for a string inverter because each microinverter handles the DC conversion on-the-fly.

Pros

Individual panel darkening has a minimal effect on the overall system because each microinverter is responsible for converting DC to AC on that panel. A string inverter design would have the entire system produce less electricity when one panel is shaded, but this is not the case here.

You can add microinverters to your solar system at a later date with ease. Installing microinverters on the back of new solar panels is a must.

As with power optimizers, microinverters make it possible to monitor the solar system at the panel level, allowing any issues with the solar output to be discovered with greater ease and precision.

Cons

Microinverters are the priciest type of solar inverter. The advantages may easily outweigh the disadvantages, especially if shadowing is an issue in other circumstances.

Repairing or replacing a microinverter located on the back of each solar panel is more challenging.

CPS SCA8-12kW Series

String inverters (Grid-tie)

String inverters are the most prevalent type of solar inverter. One inverter connects a long string of solar panels, converting their output into AC power.

Pros

String inverters have been on the market for decades and have worked out most issues. These solar inverters are also the most cost-effective solution.

As an alternative, string inverters can be found near a ground mount or on the side of your home’s exterior wall. You can quickly inspect and repair or replace the inverter from here.

Cons

String inverters are dependable, but they don’t optimize solar energy output and other inverters. Because a string inverter is linked to a series of solar panels, even a small amount of shadowing will reduce the entire string’s power production.

On the other hand, the string inverters are only able to monitor the entire system, not individual panels. As a result, it can be problematic for individuals who desire a more granular degree of monitoring regarding solar production difficulties.

Hybrid inverters (Off-grid)

With this inverter, a battery is installed, and the inverters are set up. In addition to supplying the battery with DC power, the inverter also provides AC power to the grid and your home’s appliances.

Using MPPT can determine how much charge your battery needs and when it’s cost-effective to take that charge from the grid. When the battery is fully charged, you can use this charge controller to return any extra power to the grid. This inverter can go into standby mode rather than shutting down completely should a problem emerge.

What is right for you?

One solar panel may be better suited to your needs than another. A string inverter may be a suitable option if you seek a low-cost solar inverter. On the other hand, power optimizers or microinverters might be a better choice if your solar panels are at risk of being shaded.
