Solar PV Monitoring
Using our remote control technology, we have created a compact and versatile Solar PV monitoring solution, Watchdog2 ™, for Kaco-USA. The Watchdog2 is capable of communicating with Kaco Solar PV inverters across an RS-485 bus, and stores the inverter data in a temporary buffer. The Watchdog2 is network ready, and a standard browser can be used to view instant and abbreviated Solar PV data. Similarly, the Lauritzen Heimdal™ iPhone app can be used to view inverter data. The Watchdog is designed to fit inside Kaco inverters, and is easily connected view a standard ribbon cable.
The Watchdog2 incorporates the following hardware features:
- Capable of interfacing up to 3 Kaco inverters
- Ethernet 10/100 Base-T
- Battery backup RTC, battery life > 20 years
- 170 hours of detailed inverter data storage
- Storage of abbreviated Solar PV data
- Pulse input, can be used for anemometer or external pulse-energy meter
- Temperature probe inputs for PV-module or Ambient temperature measurements
- Spare RS-485 input for external energy meter
- 4.75V to 5.5V supply, less than 1W power consumption
- Extensive LED diagnostics
- Push buttons for Reset, Server Contact and Input Scan
- Integrated communication software to operate with Lauritzen Valhalla server which enables remote client management and communication
- Integrated web server to display instant and abbreviated inverter data
- Integrated mobile-client server to enable Lauritzen iPhone/iPod/iPad Heimdal app
