The tool enables the installer to adjust settings and perform firmware upgrades besides supporting him in detecting error sources, like over- or undervoltage - without the need to open the inverter. The error memory of each inverter can be read and stored - facilitating maintenance and on-site service. Furthermore, detailed information of every inverter can be monitored and adapted like general settings or isolation.
The service software is offered within a kit, consisting of a custom Delta RS485 cable and a USB to RS485 adapter. The kit can be purchased directly from Delta and the software can be downloaded free of charge from the website http://www.solar-inverter.com/... and is compatible with Windows 2000, Windows XP, Windows Vista and Windows 7. The connection procedure can be realized easily: One inverter of the PV installation should be connected via the RS458 to the Delta RS485 cable and adapter. The adapter can be attached to a USB connection of a PC or notebook. Then the service software can be started and the installer is able to check the complete installation. Via the RS458 every controller can be accessed. The solar inverter service kit is an ideal tool for professional installers of Delta inverters.
