Our expert and consumer reviews of the leading brands of residential sized solar inverters show the best solar inverter to suit your home in 2020
Solar inverters are an integral part of every solar power system. They perform two key functions:
All solar panels generate Direct Current (DC); a solar inverter is required to convert this into Alternating Current (AC), the form of electricity usable by your home.
The operating conditions of solar panels - sunlight intensity and panel temperature - fluctuate throughout the day. This means that the possible solar panel voltage and current are always changing as well. In a process called Maximum Power Point (MPP) tracking, the solar inverter dynamically selects the exact combination of the two that will produce the most power.
Current-Voltage (I-V) Curve. This is an example of MPP tracking in action. Here, the solar inverter sets current & voltage to point b for maximum output.
There are two categories to consider when deciding on the right solar inverter type: the solar inverter technology, and the type of solar power system the inverter is for.

The solar inverter you choose will need to be compatible solar system type you are installing:
You can learn more about each solar power system type below
A grid-tied system is the most common type of solar system. It has no solar battery for backup power and utilizes net metering to maximize savings. Solar panels are mounted on your roof then wired together, and the power generated flows into an inverter where direct current (DC) electricity is converted into alternating current (AC) electricity. This electricity is either used by your home or is exported to the utility grid.
In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. The solar electricity generated by your panels that your home does not use is stored in the battery instead of being sent to the grid, which reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.
Off-grid solar systems are not connected to the grid at all, so all of your energy needs must be met by the sun. There is no utility to fall back on. The solar installation needs to power your home not only during the day, but after dark as well, so many solar panels and a large battery system are required. These systems are often expensive and don’t make sense for homes that have access to the grid.

We had a pair of SunnyBoys installed on '07. Six years later, one of them died. Since this model had been discontinued, and because ours was out of the wimpy warranty, we had to ditch the one good one and replace the pair with a brand new SB 5000US. Now the second one (SB 5000US) has died after 11 years. SMA's support is virtually nonexistent. Our installer went out of business, and they offered no help in finding another one. It's not hard to read between the lines: they don't give a damn about homeowner-customers.

The Primo is a transformerless inverter and the snap inverter design makes it very easy to install. The connection unit bolts to a wall and the inverter hinges into the connection unit and is attached by two screws making the inverter very easy to remove and service. Fronius is the only inverter manufacturer that can replace boards if there is a problem, usually an hour job. It has two maximum power point trackers, so you can have strings facing different directions. It has very low warranty claim rate unlike the IG. The monitoring can be done via wifi or ethernet and is very simple to configure. On Fronius' solar website, you can look at AC volts and amps, DC volts and amps, mppt 1 power, mppt2 power, and total power. If you don't have any shading, definitely go with a string inverter and this is a good one. Less components to fail versus Enphase - inverter behind every panel in an extreme environment.

Do not believe the hype that your electric bill will go away. It will not. I waited for one year to write this review to see if the promises made would materialize. They don't. All i have to say is that during the one of the hottest and sunny months of the year, I paid for electricity. Do not buy or install. This is the biggest lie going so far.
