OUTDOOR SOLAR INVERTER The APS-Series are outdoor PV central inverters for large PV fields with voltages up to 1500 VDC. The APS-Series is a plug and play solution for your installations. It includes all necessary parts: IP65 outdoor cabinet made for desert installations cooling system with heat exchanger o o automatic cleaning function of the water to air heat exchanger Easy to clean air to air heat exchanger with no filter mats internal maintenance free air dryer to avoid corrosion AC circuit breaker fuse protected DC combiner optionally with current monitoring DC coupling in case of an inverter fault Modbus TCP or Real Ethernet communication interfaces Hybrid System for Solar and Storage (connect PV and batteries at different dc inputs) The cabinet is completely closed. By the aid of an air to air heat exchanger the cabinet is cooled, a water cooling circuit is used for the IGBTs and inductances. With this cooling concept the APS-Series is very robust against dust and moisture. The APS-Series is supplied with all necessary control systems. In standard an optical MODBUS TCP interface is installed, optionally a PC-based monitoring system can be integrated.
