Inputs:
8 inputs for current transfor-
mers STWA1 or STWA1H
(max. 100 A)
Not connected inputs discon-
nectible
Sensitivity adjustable AC
0,3…2,4 A (lower values by
leading the monitored line
multiple times through the
transformer)
Autocalibration of inputs
Enable-input
Function
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
of an inverter or a fuse is detected
and reported. The operator can
initiate repair immediately and
saves downtime.
The SolarYes is a simple, easily
understandable and economical
solution, that protects PV-systems
from downtimes.
The device is mounted in a switch cabinet or a distribution
box. The current is measured contactless with simple
and solid current transformers, that are mounted over the
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).
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.
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.
Current-Relay SolarYes
Monitoring of Function at Photovoltaic Systems,
Detection of Failure at Inverters, 8 inputs
Displays and Controls:
8 LEDs for inputs
8 LEDs for alarms
4 LEDs for display of state and programming
2 LEDs for relays
1 LED enable-input
3 pushbuttons
Other features:
2 change-over contacts, nc and no individually
programmable
Autocalibration for easy startup
Power-saving (Eco-Mode), disconnectible
Power consumption <0,5 W, <1,2 VA
Universal supply-voltage AC/DC 24-240 V
Housing for DIN-rail mount, 70 mm, mounting height
55 mm
For measuring the current, cur-
rent transformers STWA1 and
STWA1H are used, one for every
monitored line.
The STWA1 consist of a climate-
proven sealed-in coil with 2 x 1
m cable.
SolarYes AC
Part number: S225535
Current transformers STWA1 and STWA1H
Part numbers:
S225201 STWA1
S225506 STWA1H
The STWA1H can be xed on a DIN-rail or mounted
with 2 screws. The electrical connection is made via
pluggable terminals. A built-in LED lights up at currents
> app. 2 A.
The inner diameter of both current transformers is
11 mm, the maximum current is 100 A.
