6 FAQs about Which inverter module has greater power

Is there a right combination of PV module and inverter?

What seems like a double dilemma at first, is actually the solution. There is in fact a right inverter for every available module technology. Yet, it is not always easy to find the right combination of PV module and inverter. The modules simply have too many different characteristics. There are various sizes and power classes.

How to choose a PV inverter?

The PV industry is using high-current modules to combat rising system costs. This type of module consists of M10 or larger PV cells, which can accommodate correspondingly high MPP currents (>12 A). When it comes to choosing an inverter, the I SC PV short-circuit current (“SC” stands for “short circuit”) is always the deciding factor.

Can SMA inverters be used with high-current modules?

SMA inverters can easily be used with high-current modules. The absolute limit is the maximum connectable short-circuit current ( I SC PV) of the inverter. The maximum input current (I DC max) of the inverter is not an absolute limit in the selection of the PV module. All SMA inverters can exceed I DC max without any problems.

What is a string current in a PV inverter?

Using an inverter with 12.5A MPPT input current the string current (green), voltage (blue), and power output (red) are as shown in the graph below. In the same situation when there is high irradiance and the PV module current reaches 16.3A. the string current is limited by the inverter at 12.5A.

Which inverter is best for 210mm G12 modules?

At the same time, the inverter with a greater current input has smaller losses from overload and current limiting. For 210mm G12 modules, there is a sizable amount of current limit power loss when using a 12.5A inverter. It is more appropriate and advisable to choose a single string of 16A or install more inverters.

How does a PV inverter work?

In normal use, both "grid" and "backup" are connected to the inverter's AC port, and the inverter is configured as grid tied for injecting PV power into the grid. In this mode there is no way for the inverter to decide if the power it injects will end up on the grid port or the backup, power will flow towards the loads no matter where they are.
