While a solar power system has various components, the solar panel inverter is the most indispensable one, as you cannot run electrical appliances without one. It is a device that converts Direct Current (DC) produced by the solar panels into Alternating Current (AC). This is a crucial task because all appliances, be it lights, fans, televisions, refrigerators, or even printing machines, cannot function on Direct Current (DC) – making the solar panel inverter an essential part of solar PV systems.
But even though a solar panel inverter is a key component of PV plants, there is still a lack of knowledge about the device. Thus, we are going to answer some of the most frequently asked questions about solar panel inverters in this article, so make sure you continue reading!

What is the Difference Between an On-Grid and Off-Grid Solar Panel Inverter?
An on-grid solar panel inverter is designed to be used with on-grid solar PV systems, which operate by remaining connected to the local electricity grid. Although solar energy is the primary power source, the PV system relies on the public grid for backup. These types of plants are most commonly used in households as they help reduce monthly power bills.
Similarly, an off-grid solar panel inverter is designed to be used with off-grid PV systems, which function independently of the local grid. The PV system does not rely on the grid to produce electricity, and solar energy is the primary power source. These types of plans are best suited for remote places or areas with no access to the public grid.
How Should I Determine the Size of a Solar Panel Inverter?
When you buy a solar panel inverter, you will find that all inverters vary by size or capacity, which is typically measured in Watts (W). However, you need to consider your energy requirements to determine the required capacity of the solar panel inverter. Additionally, you must also consider the size of your PV system. For instance, if you want to install a 5-kW PV plant, then the solar panel should be able to produce the same amount of energy. However, it is best to choose an inverter with a slightly higher capacity than your estimated value.
Should I Buy a PWM or MPPT Solar Panel Inverter?
Solar panel inverters are classified into two types: Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT) – both of which are technologies. While PWM has been in use for decades, MPPT technology is recent. However, today, most people prefer MPPT solar inverters as they have a much higher efficiency of up to 95%. On the other hand, PWM solar inverters are 65-70% efficient. But another key difference between the two is their price point, as MPPT technology is quite expensive.
What Safety Features Should a Solar Panel Inverter Have?
Although the safety features of a solar panel inverter vary from one brand to another, there are a few that you should always consider. These include anti-islanding protection, dual MCB protection, IP 65 protection, overload handling capacity for heavy-duty appliances, low start-up voltage, and MNRE and IEC compliance. The availability of these safety features will ensure that your inverter is protected against short circuits, fires, and other such hazards.
Where Can I Buy a Solar Panel Inverter?
Today, solar panel inverters are easily available online and offline. However, the key is to choose a reliable and reputable brand like Luminous to ensure that you’re getting your money’s worth. Luminous is India’s leading solar solution provider, and they offer high-quality, efficient, and high-performance solar panel inverters.
