Maximum power of string inverter

How much power does a string inverter have?

Before 2013, 20kW string inverters were considered high-power. In 2014, 28kW appeared, and the 40kW ones followed by in 2015, and the power increased at a rate of 10kW per year thereafter. Until 2017, the 1500V PV system promoted the breakthrough of 100kW inverters, later reaching 200kW and then 300kW.

How many strings can be connected to a solar inverter?

Here are the results we calculated: This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!

How to calculate a maximum power limit for a PV inverter?

One method of max current is 1.25 X I sc. Locate the inverter’s maximum PV power and the module’s power. (4800 W) / (360 W) = 13 Maximum number of modules total After calculating the low and high limits, you now can finalize the array configuration within those limits. Here are the results we calculated:

What is a maximum current limit on an inverter?

Inverters have a maximum current limit, exceeding this limit may damage the inverter and void the warranty. Inverter limits can be displayed differently, sometimes it’s Isc and sometimes it is max current (typically 1.25 X Isc). From the example above, it specifies a maximum short circuit current.
