Solar Inverters (Updated for 2022)

Our portfolio of solar inverters include both grid tied and off-grid solar panel pv power inverters.  We provide wholesale solar prices for retail customers for any type of wind and sun project. The DC power inverters are the heart of a solar photovoltaic system; therefore the reliability factor is crucial at the selection. These solar products convert DC (direct current) electricity generated by photovoltaic modules or wind turbines and stored in batteries into AC (alternating current) power required to run conventional appliances and/or for connection to the grid.

What is a power inverter?

An inverter is a critical piece of equipment in any PV system. The inverter takes DC power, either from your solar panels or batteries, and turns it into AC power, ready and usable for your household appliances. Grid-tie and off-grid solar systems use different types of inverters! Do not mix the two.

Grid-Tie Inverters

In a utility grid-tied system, solar panels connect directly to an inverter which ties into your main household electrical panel. It sends power into the home to run appliances and turns back the meter with excess energy. Grid-Tie inverters come in several options: string inverters, microinverters, and optimizers. Each varies with features and costs.

String Inverters Installed

String Inverter

  • Lowest cost
  • Multiple MPPT inputs
  • Secure Power Supply provides daytime backup during an outage


Though string inverters derive from the oldest technology, modern string inverters have improved substantially and provide a cost effective option for many. In a string inverter system, solar panels are wired in a series string for high voltage (typically 300-600VDC) We have sold the SMA Sunny Boy and SMA Tripower string inverters for years and recommend these for installations where solar panels stay relatively free of shade. In all the other occasions the recommended inverter would be the SolarEdge.

Solar Optimizers Installed

PV Optimizers

  • Easy and safe installation
  • Module-level monitoring included
  • Large string sizes


You have shading issues? Optimizers are DC-DC converters that connect to each solar panel, similar to a microinverter but a central inverter still handles the DC-AC inversion. Solar panel optimizers attach to each panel for easier and safer installation, easy expansion, bigger string sizing, and module-level monitoring. SolarEdge is a leader in optimizer technology and one of the most popular residential inverters. We have this installed on many occasions. The solar panel optimizers combine the best features with a competitive price. We do sell SMA Tigo optimizers as well.

Buy solar optimizers

Solar Microinverters Installed


  • Easy to install
  • Module-level monitoring with IQ Envoy
  • Expandable and modular


Microinverter systems have a small inverter attached to each panel. This type of inverter costs more, but it is also expandable, safe and easy to install, and is capable of monitoring every individual solar panel. Because each panel can operate independently, microinverters are a better option if there is shade on part of the solar array from trees, buildings or other obstacles. Microinverters tend to be the most expensive inverter system, but they provide key benefits like ease of installation, expansion, and module-level monitoring. We recommend Enphase Energy IQ microinverters for anyone looking for these features.

Pure Sinewave Off-Grid Inverters

Pure Sinewave

  • More expensive
  • High quality output power
  • Compatible with most appliances


You will hear inverter manufacturers use phrases such as pure sinewave and modified sinewave. This is a measurement of the quality of the AC output power. Pure sinewave inverters put out power that is as good, or potentially better, than what is coming from the power grid. Almost all appliances will work with pure sinewave inverters.

Buy Off-Grid Inverters

Modified sinewave off-grid inverters

Modified Sinewave

  • Lower cost
  • Low quality output power
  • Only compatible with certain appliances


Modified sinewave inverters have lower power quality which causes issues with certain appliances. Motors, pumps and compressors (like your fridge) will tend to run hotter and burn out quicker. Modified sinewave inverters can be problematic for sensitive electronic devices, often causing lines on your TV screen and a buzzing sound from the speakers. Some appliances won’t work at all on a modified sinewave inverter. For these reasons, we recommend sticking with a pure sinewave inverter unless you are sure your appliances can work on modified sinewave power.

Your solar panel energy system can’t send power to either your home or the utility grid without some help. A solar panel power inverter is what provides that help. The main purpose of the solar inverter is to translate or “invert” / “convert” the solar energy—generated by your solar panels—from DC to AC so that your home and utility grid can use it.

10 to 20 years
Typically, grid tie / connected inverters have a lifespan ranging from 10 to 20 years. You should expect most good quality units to last at least 10 years. Solar panel power inverters have warranties ranging from 5 to 12 years with an increasing number of manufacturers offering pay for service warranty extension. These inverter guarantee extensions can go up as 20-25 years. 

No, normally solar inverter do not need servicing or maintenance during their lifetime; although periodic software updates are needed in order to have your system up and running. While solar panels have no moving parts and can be expected to continue working past 25 years, inverters are arguably the most likely part of the solar panel system to fail. Depending on the brand, they need regular replacement every 5-10 years.

A good quality solar energy inverter is an essential part of your panel set up. it’s an intelligent piece of kit that connects to your system and should be placed where you can easily get at it. It has two jobs:

  • to maximise the available energy being generated from your panels.
  • to change the DC current from the panels in to AC current so that it’s compatible with everyday appliances and exporting to the national grid.

There are different ways to achieve this and advantages for each approach. (We go in to the technical detail below.)

Type of solar power inverters

String inverters

A string is a chain of panels connected together in series. This is the most basic inverter system. All the panels in a string must be at the same pitch and orientation, otherwise there will be inefficiencies in the system. Many string inverters have 2 or even 3 MPPTs (Maximum Power Point Tracking), which means that you can have a different string of panels on each MPPT. This could work well for an east/west set up.

Most inverters now have internet connection capability, so you can keep an eye on your system using apps or web browsers, even when you’re away. The technology also raises awareness of your energy usage, encouraging you to be more sustainable, and save more money.


One of the disadvantages of string inverters is that if there is a fault or shading on one panel in the string, it will affect the performance of all the panels on the same string. In a microinverter system each panel has an inverter all to itself. Each panel is therefore isolated so any faults or shading will be isolated. As microinverters are often hooked up to the internet, problems with specific panels are quickly and easily identified, saving a huge amount of investigation time.

Optimised inverter system

A hybrid of the microinverters and string inverters,  separates the two jobs of an inverter. There are optimizers behind each panel which carry out the role of MPPT therefore isolating any shading or fault issues. These optimizers are connected to a central inverter which can work more efficiently as it is always presented with the same voltage from the panels (string inverters have to deal with variable voltages). These systems are also internet connected which allows pro-active maintenance. So if there’s a fault, your installer will get an email alert and can respond quickly and accurately.
