SOLARYES - Current Relay - S225535

  • S225535
  • Product Type IP00 motor, IP20 electronics
  • Supply voltage AC/DC 24 - 240 V
  • Execution IP55 motor, IP20 electronics
  • Output function Outputs/Relays
  • Measured value PA material reinforced with glass fiber.

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 existing system is possible. Over the course of 24 hours occurring minimal currents (at night there can be wattles currents, caused by interference suppression capacitors in the inverter) are automatically measured and faded out in the evaluation.

The minimum response limit of 0.3 A allows measuring of low current-levels. The limit can be 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 electroacoustic transducers. The connection of an alarm system or another monitoring unit also is possible.

Inputs

  • 8 inputs for current transformers STWA1 or STWA1H (max. 100 A)
  • Not connected inputs disconnectible
  • 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

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
  • Accessory: Front mounting kit type ER4
