solaredge vs enphase

In the solar industry, SolarEdge and Enphase are two of the biggest names when it comes to inverters, optimizers, and microinverters. When choosing between SolarEdge vs. Enphase it’s important to understand the differences between their products.

SolarEdge vs. Enphase: key differences

SolarEdge and Enphase are the world’s leading manufacturers of solar inverters. Collectively, they represent 95% of the global market for these products.

They also lead the market in the US, with no competitors coming close to their market share. Although they’re often seen as direct competitors, their system configurations are actually quite different, so it’s important to understand the differences between these brands and their products.

Inverters are an essential part of any solar system: this key component makes it possible for virtually anyone to set up and run a home solar system. Essentially, the purpose of an inverter is to convert direct current (DC) into alternating current (AC).

Photovoltaic (PV) solar panels absorb the sun’s rays and convert their light into energy, which is produced in the form of DC electricity. However, the appliances in our homes run on AC power, so in order to use the power generated by the solar panel, you first need to convert it to AC.

This is what solar inverters do, as well as performing Maximum Power Point Tracking (MPPT), which ensures that the panels are working optimally before voltage conversion. In this way, inverters guarantee that you get the maximum power output from your solar system, and have as much energy as possible to power your devices and appliances.

While Enphase’s solar systems are configured around microinverters that both optimize and convert the current coming from the panel, SolarEdge uses power optimizers on the panels with separate inverters. Therefore, in Enphase’s configuration, the current is already converted to AC when it leaves the panel, while, with SolarEdge this conversion happens later.

Let’s talk a little about each company, what they do, and who their products are best suited to.

SolarEdge vs Enphase: Who are SolarEdge?

SolarEdge is based in Israel and, as a major supplier of inverters, is the leading manufacturer of power optimizers in the US, with a market share of around 60%. Although they also provide commercial and electric vehicle solutions, SolarEdge focuses mostly on residential applications.

SolarEdge’s systems are configured with module optimizers, meaning there is a power optimizer on each solar panel. Each individual optimizer maximizes the current coming from the PV unit before it is sent to a central or string inverter.

The inverter can be installed away from the PV units, such as in your garage or house, as it doesn’t need to be located next to the panels.

In short, rather than performing power optimization and current in a single device conversion, SolarEdge’s systems rely on two separate pieces of equipment for each function.

Their signature power optimizers balance or “condition” the DC current produced by the solar panel, maximizing its efficiency and ensuring it delivers the maximum amount of power. This current is then sent to a separate power inverter that converts it into AC so that it can power regular household appliances and devices.

SolarEdge’s power inverters are designed to work with their power optimizers and vice-versa.

These systems can use of either central or string inverters:

  • Central inverters: Central inverters receive the total voltage from all of the solar panels in your system and convert the current from DC to AC. They allow you to set up a simplified system that is easy to design, install, and track the power output in the whole system, with minimal up-front costs. However, they may compromise on safety, can be more expensive to wire, and make it harder to expand your system in the future.
  • String inverters: These are essentially a hybrid between central and microinverters, with a chain of inverters which are separate from the solar panels.

These systems are generally more affordable than configurations that rely on microinverters, such as Enphase’s model. According to SolarEdge, their approach allows you to maximize your system output at a lower cost than with microinverters.

What sets SolarEdge apart from other systems that use central and string inverters is that you can monitor the performance of the panels individually using their monitoring app. Using the app, you can activate and configure your system, as well as monitor its performance and check for issues, all from your smartphone.

Something that sets SolarEdge apart from their competitors, including Enphase, is that they were the first manufacturer in the world to offer a combined electric vehicle (EV) charger and solar inverter. The ultimate product for eco-friendly drivers, its system allows you to charge your vehicle using solar energy, with charging speeds two and a half times faster than other EV chargers.

SolarEdge vs Enphase: Who are Enphase?

Based in California, Enphase manufactures the most popular microinverter for sale in the US, having long supplied famous brands such as SunPower and Panasonic. This means if you buy a solar panel from either of these companies, it will come equipped with an Enphase microinverter.

Like SolarEdge power optimizers, Enphase’s microinverters are coupled to each solar panel on your roof. However, the key difference is that each device conducts both power optimization and conversion on your roof, rather than connecting to a separate inverter.

Under this configuration, the current is converted to AC power before it leaves the panel.

Each microinverter contains a self-contained inverter with an integrated MPP tracker, which is the ultimate smart solar system that is safer and more efficient than configurations with central or string inverters. Each panel is controlled separately, so if one panel experiences partial shading or has a power failure, the microinverter can make sure that this doesn’t impact the system overall and you still enjoy a constant supply of power.

Additionally, because there is less DC wiring required, there is a lower risk of fire or electric malfunction, making them safer. These systems are also highly flexible, making it easier to expand them at a later date if required.

On the other hand, these are highly complex systems that involve a larger upfront investment and higher maintenance costs.

Enphase is a leader within the world of microinverters, and they’ve also moved into offering energy storage products. Their battery, Encharge, will store the power generated by your solar panels so that you can rely more on renewable energy and less on the grid even at night.

They also offer Ensemble kits that include backup storage as well as a smart inverter that can detect power outages and automatically switch to backup battery power. This means you’ll never need to worry about power outages, as the system will automatically switch over to stored solar energy when required.

You can set your system to provide backup power to all of your home appliances and devices in case of an outage, or only a few emergency devices. This level of flexibility allows you to choose a full or partial home backup depending on your power needs and how much solar energy you have.

Like SolarEdge, you can manage your Enphase system from your smartphone using their Enlighten app. The app lets you check a range of metrics, like how much energy your panels are producing, your power use, and how much is stored in your battery.

You can even connect the Enlighten app to a virtual assistant and control everything using voice commands.
