What to do if my Steca Tarom 4545 Controller indicates 'Wrong PV polarity'?
If your Steca Controller indicates 'Wrong PV polarity', it means the solar module is connected with the wrong polarity. To resolve this, connect the solar module with the correct polarity.
What to do if my Steca Controller indicates 'Wrong battery polarity'?
If your Steca Controller indicates 'Wrong battery polarity', it means the battery is connected with the wrong polarity. To fix this, connect the battery with the correct polarity.
What to do if my Steca Controller shows an overload error?
If the Steca Controller displays an ‘Overload’ message, it means the maximum permissible load current has been exceeded, and the controller has switched off the load output. To resolve this: 1. Switch off the loads to reduce the load current. 2. Switch on the loads individually. If the issue persists after all loads have been switched on, contact your dealer, specifying whether the event message occurs immediately or some time after switching on the loads.
What to do if my Steca Tarom 4545 shows 'Battery voltage too high'?
If your Steca Controller displays a 'Battery voltage too high' error, take these steps: Remove any other charging sources connected to the battery to see if that corrects the problem. Also, measure the battery voltage with a voltmeter and compare it to the controller display. If the values deviate greatly, the controller might be damaged.
What should I do if my Steca Tarom 4545 Controller displays 'Battery voltage too low'?
If your Steca Controller indicates a low battery voltage, it means the battery's cell voltage has dropped below the minimum. If a directly connected load has deeply discharged the battery, charge it with an external device. If the message appears frequently, check the battery's capacity and replace it if needed. Also, measure the battery voltage with a voltmeter and compare it to the controller's display; a large deviation suggests the controller is damaged.
What to do if my Steca Tarom 4545 shows an overload?
If your Steca Controller displays an overload message, it means the maximum permissible load current has been exceeded, and the controller has switched off the load output. First, switch off some loads to reduce the total load current. Then, switch the loads back on individually. If the message reappears after all loads are on, contact your dealer, specifying whether the message appears immediately or after a certain time.
What does pre-warning of deep discharge protection mean on my Steca Tarom 4545 Controller?
If you receive a pre-warning of deep discharge protection on your Steca Controller: * Charge the battery. * Set the switch-off threshold of the Load deep discharge protection under ‘Main menu’ ? ‘Output settings’ ? ‘Load’ ? ‘Low volt. discon. - LVD’ ? ‘Disconnection thresh.’
What does 'PV current too high' mean on my Steca Tarom 4545?
If the Steca Controller displays ‘PV current too high’, it means the maximum permissible module current has been exceeded because the solar module is over-dimensioned. Contact your dealer for assistance.
What does it mean when my Steca Tarom 4545 displays a 'Battery voltage too high' error?
If the Steca Controller displays a ‘Battery voltage too high’ message, the cell voltage of the battery has risen above the maximum value. To address this: * Remove other charging sources connected to the battery. Is the problem corrected? * Measure the battery voltage with a voltmeter and compare it to the controller display. If the values deviate greatly, the controller is damaged.
How to fix a 'Sensor defect: extern. temperature' error on my Steca Tarom 4545?
If the Steca Controller displays a ‘Sensor defect: extern. temperature’ message, it indicates a short circuit or open circuit in an external temperature sensor. Check the following: * Is the external temperature sensor cable correctly connected to the controller? * Is the cable broken or short-circuited? * Is the external temperature sensor damaged?
