SOLARYES MONITORS OUTPUTS OF INVERTERS IN PV-SYSTEMS
Its output-relays (2 potential-free contacts) switch, when there has been no current during the last 24 hours in one of up to 8 monitored lines. Thus the failure of an inverter or a fuse is detected and reported. The operator can initiate repair immediately and saves downtime.2 change-over contacts, NC and NO individually programmable
- Power consumption <0,5 W, <1,2 VA
- Universal supply-voltage AC/DC 24-240 V
