6. Overview The PVS300 transformerless string inverter converts direct current DC generated by the solar arrays to single phase alternating current AC The AC is then fed to either the public electricity grid or to a load circuit which is connected to the public electricity grid PVS300 is suitable for small and medium size solar systems PVS300 is designed for installation in air cooled outdoor rated enclosures Installation is performed with the help of a mounting plate The DC and AC cable connections at the inverter are made with quick connectors Two variable speed fans operate on a demand basis A stirring fan prevents the formation of heat pockets around the control board A cooling fan provides air flow to the heat sink and power electronics circuit boards The fresh air intake for the cooling fan is located in the cabling section of the inverter A narrow gap between the PVSD300 and the mounting plate works as an air vent PVS300 provides comprehensive functions for system protection system supervision and external communication After the inverter has been installed and commissioned it operates automatically according to the following principle 22 Operation basics and hardware description 1 As the sun rises the inverter wakes up when there is enough daylight for the solar modules to generate DC voltage in excess of the minimum inverter operating limit 2 After waking up the inverter verifies the status of the power
