Solar Panel String Configuration

The mppts optimise each input separately.

Solar panel string configuration.

When you wire in series there is just a single wire leading from the roof for each string. A panel string is a group of panels wired into a single input on your inverter. The fronius solar configurator 4 0 helps you determine the number of solar modules for a system and how they are connected to your choice of fronius inverter. For example this grid tied system contains 24 mission solar 360w panels and one sma sunny boy 7700w inverter.

The fronius string configuration tool fsc tool assists users with system design. You could even have a different type of panel for each string. Wiring solar panels when using a string inverter. It does not guarantee the configuration is appropriate for your use.

When wiring multiple module strings together in parallel e g. Pv solar systems can be dimensioned with ease and optimum results. Positive to negative voltage is increasing while current stays constant. String inverters have a rated voltage window that they need from the solar panels in order to operate.

In the configuration above each string can have a different numbers of panels and each string can face different directions. The inverter appropriately called a string inverter has three string inputs. Positive to positive and negative to negative current is increasing while voltage stays constant. When a solar installer wires your solar panels in a series each panel is connected to the next in a string the total voltage of each solar panel is summed together but the amps of electrical current stay the same.

The various configuration options are quick and easy to obtain and clear presentation and intuitive functions are included. It also has a rated current that the inverter needs to function properly. By using the fsc tool the user claims all responsibility for the accuracy and validity of the results including but not limited to system design performance and code compliance. This is because each inverter input is connected to a separate maximum power point tracker mppt.

You need to understand how different stringing configurations impact the voltage current and power of a solar array. Wiring solar panels in series.
