The customer support is excellent. Fronius offers product demos and training. The company's goods and service have been awarded with multiple prizes.
Primo is a highly-demanded single-phase inverter by Fronius for home applications. Its popularity caused temporary disruption of supplies and insignificant failures. Anyway, the unit is mostly positively feedbacked, and the manufacturer have resolved all the troubles quickly. Another top solution for residential use is Primo.
All the snap in models have an inbuilt active cooling, which makes the inverters so reliable. The fan-based cool system accelerates heat extraction, reducing thermal stresses and increasing the outputs in high-temperature conditions.
An optional addition of Ohmpilot allows automatic usage of excess energy for water heating.
SolarEdge
SolarEdge's exclusive smart inverter system integrates DC-optimisers for panel-level monitoring and maximum power production. Besides, the technology allows to connect more panels (up to twenty-two) in a string, maximizes safety, decreases the impact of shading and panel failures.
Though it is more expensive and time-consuming to install and set up SolarEdge's inverters, they have lots of advantages, such as flexible design and lay-out. They detect possible issues early, which allows fixing the troubles effectively.
Moreover, if an inverter or power grid shuts down, optimisers reduce the voltage of DC-cables down to 1V. This is much safer in comparison to traditional panel strings with 300-600V.
The power optimisers are covered with a 25-year, and the inverters – with 12-year warranty (extendable to 20 or 25 years).
The android-based app for remote tracking is superb, and Wi-Fi option allows providing output data for each individual module, which helps to detect faults.
ABB (FIMER)
The manufacturer offers both one- and three-phase string inverters, which are high-power and cost-effective. The installation of the units is simple, their capacity is between 2 and 50 kilowatts. The products are meant for solar installations used by homes or businesses.

The warranty period is five years, with 10-, 15- and 20-year options of free extendable warranty. The products are reasonably priced in comparison with other popular manufacturers and are up to 97-percent efficient.
ABB used to be among the leading manufacturers of qualitative string inverters before its acquisition of Power One Aurora seven years ago. The old-gen Aurora inverters caused a lot of warranty events and service problems ABB had to resolve. It has been noticed that the customer support provided by the industrial colossus is a bit slower than that by its rivals.
At the beginning of the current year, the solar business of ABB was purchased by Italy's reputable solar inverter maker FIMER. The fresh owner will probably strengthen the company's position in the industry and will be improving the customer experience.
The newest UNO-TL-DM-PLUS and UNO-TL Series are feedbacked positively. All products of the UNO family feature a plug-and-play interface and Wi-Fi monitoring.
The monitoring is performed through Aurora Vision® Plant Management online platform. Besides, the manufacturer offers an updated Plant Viewer solution for monitoring as well as a smartphone application – Energy Viewer. The monitoring portal provides the basic data (but not much tech info like the voltage and power output of individual strings, helping to detect and fix the troubles).
The older models of the UNO and TRIO (three-phase) family can be supplemented with VSN300 logger cards to monitor the inverter performance remotely via WiFi.
SMA Solar Technology
Germany's company manufactures qualitative and reliable inverters and other solar products. Besides, the firm offers lots of SW and apps for monitoring and control, including Sunny Home Manager, Sunny Portal, Sunny View and SMA Energy Meter. The solar manufacturer has been awarded with multiple prizes including INTER SOLAR, Smart Energy and EES awards. Until 2016 when Fronius released its snap-in line of inverters, SMA had been considered the top producer of string inverters.
The new line of AV inverters has no display panel – it provides all the data through WiFi. Because the outdoor conditions can cause fault to a display, the AV family of inverters have fewer failures and warranty cases.
The larger-scale three-phase inverters for commercial application are made in Germany and are considered to be among the top in the sector. The Sunny Tripower line of inverters offers the top reliability. SMA's best central inverters include Sunny Highpower, Sunny Island and Tripower Core 1.
SMA's inverters are warrantied for five years, which can be extended to ten, fifteen or twenty years (for different models). The warranties cover the shipping and onsite replacing costs in case the unit fails.
The only drawback of the products by SMA is their expensiveness.
Enphase
The company with HQ in the USA is the leading and best-known microinverter producer worldwide. As of 2021, it has produced over 17mln devices. Its micros are covered with a 25-year warranty.
Similarly to power optimisers, microinverters are attached to each individual PV panel, which boosts design flexibility, safety and performance. The efficiency of microinverters is higher, but they are more expensive than optimisers.
Enphase's micros are incompatible with Powerwall by Tesla. However, there are storage products by Enphase compatible with same-brand inverters.
IQ 7 Series Micros by Enphase is more suitable for home use, the units are light and their power production is 23 percent higher than that of the earlier models.
Sungrow
Established over twenty years ago, China's producer of inverters is a leader of the industry domestically and is among the biggest ones worldwide. Sungrow's devices combine simplicity, flexibility and robustness with affordability. The capacity ranges between 2 and 5 kilowatts.
