I need a very simple led driver to indicate current flowing in a Solar HWS when mains connected to heater element. Probably current flow would be in vicinity of 30A. I have a non invasive YHDC SCOT13 [input 5-100A/output 50mA/1V ] to use?

No complicated power supplies/circuit boards/inputs to computers, devices, just a very simple circuit to drive a small light emitting diode. I already have a led on the mains switch to indicate when mains available [off peak switching from supplier] but cannot find anything anywhere to drive a led when current is flowing. The thermostat in the heater element cct switches mains on/off when set temp. is reached.
