As per Statista, the total solar energy capacity is expected to increase by 30% by 2029.[1] With everyday technological advancements, there has been a dramatic increase in the efficiency and performance of solar energy systems. One such technological advancement brimming with potential in the world of solar power is MPPT or Maximum Power Point Tracking. It plays an important role in solar string inverters.

The continuous changes in the sunlight intensity and temperature can affect the performance of solar systems. The purpose of a solar string inverter with MPPT is to make sure that solar panels work at their optimal power output in all environmental conditions. This blog is to cover all the amazing benefits of multi-PPTs in solar string inverters.

Understanding MPPT in Solar Inverters

MPPT(Maximum Power Point Tracking) is an electronic that optimizes the efficiency of solar panels. The main principle at which MPPT works is to draw out the maximum power available from the PV module. It does so by making the PV module work at its maximum power point (at its most efficient voltage). Working on this principle, here is how MPPT actually works;

  • The solar inverter MPPT monitors the voltage produced by your solar panel.
  • It adjusts the current and voltage of the panel by increasing or decreasing the resistance to optimize the overall power output.
  • It matches it with the power requirements of the appliances.

How MPPT Improves the Efficiency of Solar Panels Under Varying Conditions

Several factors, such as varying temperatures, shading, and age-related degradation, affect solar panel efficiency. MPPT dynamically adapts to these varying conditions. It adjusts the resistance, current and voltage and keeps them at the maximum power point. This means that even on cloudy days, early morning or late evening, your solar panels will be able to produce significant amounts of energy.

How Many Strings Can Be Connected to MPPT?

If you connect more strings to MPPT than it can handle, it may lead to reduced efficiency. That’s why you must follow the manufacturing guidelines in this regard. However, a single MPPT can handle multiple strings, most commonly 2 strings.

What is a Multi-MPPT Solar String Inverter?

A multi-MPPT solar string inverter takes the technology of MPPT a step further as it integrates multiple MPP trackers to regulate the output from multiple arrays or strings of solar panels individually. This indicates that if your solar panels are at varied tilt angles or facing different directions, the inverter optimizes each set individually and, hence, maximizes the overall production of energy.

Benefits of multi MPPTs in Solar String Inverters

After understanding MPPT in solar inverters, you must be curious about the benefits of multiple MPPT solar string inverters. Here are some benefits you should know:

  • Increased Efficiency: Multiple MPPT inputs in solar string inverters make them draw out maximum power from each orientation or string. It boosts the production of energy significantly.
  • Adaptability to Diverse Orientations: Solar inverters with multiple MPPTs can easily manage solar panels that face different directions or have different tilt angles. It makes them suitable options for roofs with complex layouts.
  • Enhanced Reliability: When one set of panels or one string has decreased performance or is shaded, the other inverter compensates it by adjusting the other strings. It ensures the overall reliability of the system.
