What is a Micro-inverter?
A microinverter is a type of inverter mounted directly on each individual solar panel, rather than at a central location for the entire solar power system. This allows each solar panel to operate independently and maximize yield.
There are several situations in which using microinverters can be more advantageous than using central inverters:
-
Shadow: If there is shadow on one or more solar panels in your system, it can affect the performance of the entire system. With microinverters, the performance of each solar panel can be optimized independently of the others, even if part of the system is in shadow.
-
Limited space: In situations where there is limited space available to place a central inverter, the use of microinverters can be convenient because they can be placed on the roof or close to the solar panels.
-
Monitoring: Microinverters allow monitoring of individual solar panels, which can help detect problems with specific solar panels or optimize solar system performance.
-
Flexibility: Microinverters make it easier to expand the system because you can add just one panel and microinverter instead of an entire string of solar panels all connected to the same inverter.
However, it is also important to note that microinverters are usually more expensive than central inverters, so they may not be cost-effective for very large solar systems.
Are there MPPTs on a micro inverter?
A microinverter is a type of inverter mounted on each individual solar panel to convert direct current (DC) from the solar panel to alternating current (AC). Unlike central inverters, microinverters usually do not have MPPT trackers because each solar panel has its own microinverter mounted directly on the panel.
Instead of one central inverter converting power from multiple solar panels, each solar panel in a system with microinverters has its own small inverter that converts power from that particular panel. This means that each panel can reach its own power point, maximizing the efficiency of the entire system. This is different from systems with one central inverter, where all solar panels operate at the same power point.
So, unlike central inverters, microinverters usually do not have MPPT trackers because the microinverter performs the function of the MPPT tracker and converts the power from the individual solar panel to AC power.
