Current Relays Type SolarYes

Current-Relay SolarYes

Monitoring of Function at Photovoltaic Systems,

Detection of Failure at Inverters, 8 inputs

Thedeviceismountedinaswitchcabinetoradistribution

The 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

ofaninverterorafuseisdetected

and reported. The operator can

initiate repair immediately and

saves downtime.

box. The current is measured contactless with simple

andsolidcurrenttransformers,thataremountedoverthe

line at any position, e.g. near the fuses. A subsequent

installation in an existent system is possible.

Over the course of 24 hours occurring minimal cur-

rents (at night there can be wattles currents, caused

by interference suppression capacitors in the inverter)

are automatically measured and faded out in the eva-

luation.

The minimum response limit of 0,3 A allows measu-

ring of low current-levels. The limit can de reduced by

leading the monitored line multiple times through the

transformer (Ø 11 mm).

The SolarYes is a simple, easily

understandable and economical

solution,thatprotectsPV-systems

from downtimes.

In case of false alarms, e.g. with snow on the solar

modules, the monitoring interval can be extended to

up to 8 days or the alarm can be suppressed with a

switch.

Part number:

S225535

The 2 output-relays can switch alarm-lamps or elec-

troacoustic transducers. The connection of an alarm

system or another monitoring unit also is possible.
