What does an inverter do?
Solar inverters are an integral part of every solar power system. They perform two key functions:
DC to AC conversion
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.
MPP tracking
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.
Types of solar inverter
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.
Solar inverter technology
- String inverter: A string inverter is a single, standalone unit that converts power from a whole string (or strings) of solar panels. String inverters are cheap and convenient, but tend to be the least efficient.
- String inverter + power optimizer: Power optimizers are attached to each individual panel. They perform MPP tracking at the module level; the optimized DC power is then sent to the string inverter for conversion into AC power. Combining string inverters with power optimizers will increase your cost but allow your system to handle issues like shading better.
- Microinverter: Microinverters are also attached to individual panels. They perform both MPP tracking and power conversion at the module level, allowing each panel to output usable AC power. They’re good at dealing with shade (like power optimizers), and have the additional advantage of making your solar system easy to expand. They are, however, the most expensive type of inverter.

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:
- Grid-tied inverters are meant for grid-tied solar systems, the most common system type. They manage a two-way relationship with the grid, exporting solar power to it, and importing utility power from it as required.
- Hybrid inverters are designed to work with hybrid solar systems (aka solar-plus-storage systems). They have the same functionality as a grid-tie inverter, but can also charge and draw power from a battery setup.
- Off-grid inverters are used in off-grid solar systems, i.e. fully independent solar power systems, giving you back up power when the grid is down. An off-grid inverter requires a battery backup to function, and cannot be connected to the grid.
You can learn more about each solar power system type below
How do solar panels work?
Grid-tied solar system
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.
Hybrid solar system
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 system
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.

Had a solar system installed March 2020 by Lumina Sun. Activated May 2020. Both inverters not functioning from the beginning. New ones ordered and now I'm being told the Sunny Boy Inverters are not in stock and Lumina Sun has no information as to when I will receive them. I have made 2 payments on a solar system that is not functioning in addition to my regular electric bill. I am beyond mad!!!

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.

After waiting one month, after multiple phone calls, and after long waits, Enphase tells me they need more time to look into the issue! I concluded that Enphase Energy is not interested in honoring their warranty commitment! Stay away from Enphase Energy at all cost!

My inverter has failed 3 times in 3 years. Each time, the “monitoring service” has failed to notice and it takes months to discover. The inverter has stopped working again and I cannot get a response from customer service. The website only provides DIY advice and the option to talk to a bot, which also malfunctioned. It has been 4 days and I still have not been able to contact a customer service rep. The are clearly avoiding their customers.
