The maximum number of modules in series can be as much as 11..
When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps..
So you could have up to 19 panels in a string (rounding down to the nearest whole panel). String voltage = 37.6V * 19 panels = 714.4V.
You want to have an equal number of panels on each string, so let's bump it up to 16! So, 16 panels/2 strings = 8 panels in series per string..
This will give you the maximum number of modules that can be wired in a series string per that inverter and specific location. The maximum number of modules in this series string is 13. [pdf]
[FAQS about How many photovoltaic panels can be connected in series per string]
A string inverter system aggregates the power output of groups of solar panels in your system into "strings.".
A string inverter system aggregates the power output of groups of solar panels in your system into "strings.".
A string inverter is an aggregated device primarily designed to process the DC output of multiple interlinked solar panels into practical AC energy..
String inverters are a key part of many solar energy systems. They connect several solar panels, allowing them to work as one unit to convert sunlight into electricity for your home..
String inverters convert DC power from “strings” of PV modules to AC and are designed to be modular and scalable. Smaller string inverters may have as few as one input, with one PV string per input..
A string inverter connects a series or “string” of solar panels, handling the DC to AC conversion process for the entire string. [pdf]
