The number of panels, 16 vs. 20, is really more about how many kWh per day you need to meet your energy production goals. I believe the MPPT inputs on the Sol-Ark are independent so the

String Inverters In a string inverter setup, multiple solar panels are connected in series to form a "string," which feeds DC power into a single central inverter. This is one of the most common and cost

Connecting a solar panel in parallel connects multiple strings together. Electrically, this means that the voltage of each string remains the same, but the current increases by the number of strings you have
