Solar PV inverters are essential for any photovoltaic (PV) system that needs to utilise AC power. Their primary function is to convert the DC power generated by solar panels into usable AC power, which can then supply the electrical loads in a property. There are many different types of solar inverters available in the market today. In the following sections, we will explore the key distinguishing features to help you choose the right inverter for your system.
From 0.7kW inverters (perfect for new-build installations) to 350kW behemoths for commercial and utility applications, Segen carries a huge selection of world-leading inverters.

There is an electrical supply in essentially every property, regardless of the size or type of inverter. Domestic properties usually have a single-phase connection, while commercial properties have a three-phase connection. This is not the case with every site but is a good rule of thumb. The electrical supply will influence the choice of solar inverters available, with most manufacturers offering both single and three-phase solutions.
As string inverters are an affordable and reliable inverter, they’re widely used in the market. The name ‘string’ comes from their ability to connect to a group of solar panels, to the unit. The panels are connected in a DC circuit and the string is then linked to convert the inverters DC input.
Other notable benefits, Centralized maintenance: Only one inverter to manage.
Proven technology: Reliable with a long history in the industry.
Higher efficiency: Especially in unshaded, uniform solar arrays.
Maximum Power Point Trackers (MPPT’s) are built into inverters. Their key role is allowing the inverter to automatically extract as much power as possible from the connected string. By using an algorithm, the system operates as the most efficient voltage. It will allow some voltages and currents to be discovered and corrected between modules. The outcome of this means there is a higher output through the connected string(s).
Each MMPTs independently track their connected strings, so an issue with one string in the array will not affect others. As MMPTs are made by joining two strings together, shading one panel in one string by 50% will reduce all other modules in both strings by 50%. Splitting those two strings across two MPPTs would only affect the MMPT with the shaded module.
If any or one solar panel connected to a tracker fails or degrades, all solar panels connected to that same tracker will lose energy. Therefore, it is good practice for commercial systems to use an inverter with higher MPPTS. Three, four or even six trackers are built into the three-phase inverters from Huawei and Solis to ensure minimum losses over time.
