What to do if batteries are not charging with Magnum Energy PT-100 Controller?
If your batteries are not charging, check for loose or corroded battery cables and clean and tighten them. Also, the batteries might be defective and need replacement.
What to do if Magnum Energy Controller shows high battery fault?
The PT controller likely turned off because a high voltage (≥68 VDC) was detected at the battery input terminals. The controller will automatically resume operation when the voltage drops below 66.4 VDC. You can also manually clear this fault by pressing the RESET button for one second after the voltage falls below 68 VDC.
Why does my Magnum Energy Controller show no PV input fault?
The PT controller probably turned off because it didn't detect any PV power on the PV input terminals for over 24 hours. The controller will automatically start working again once the voltage to the PV input terminals is more than 5 volts above the battery voltage. You can also manually clear the fault by pressing the RESET button for one second.
What causes a high PV input fault on a Magnum Energy PT-100?
The PT controller has turned off because it detected a very high PV voltage (>187 VDC) on the PV input terminals. This is a safety measure to prevent damage. The controller will automatically start working again once the voltage to the PV input terminals is less than 185 VDC.
Why does my Magnum Energy Controller display a FET overtemp fault?
The PT controller turned off because the internal FETs (Field Effect Transistors) exceeded their safe operating temperature range (≥85°C/185°F). The fault will automatically clear, and the controller will resume operation once the FET temperature cools down below 83°C/181°F.
How to fix an internal overload fault on a Magnum Energy PT-100 Controller?
The PT controller has an internal overload fault because the current to an internal sensor has exceeded the controller’s protection limits. Try pressing the RESET button for one second to clear the fault and turn the controller on. If the fault persists, the controller may require repair due to damaged or faulty components.
What to do if my Magnum Energy Controller displays a GFDI fault?
This fault indicates that the GFDI fuse in the PT controller has opened due to a ground-fault condition. To resolve this, you should correct the ground-fault condition and replace the fuse. After doing so, press the RESET button for one second to clear the fault and turn the controller back on.
What causes an internal power supply fault on a Magnum Energy PT-100 Controller?
The PT controller turned off because the voltage from the auxiliary power supply in the controller has dropped to a low level. Ensure the unit is within the normal operating temperature range. Also, remove any cables from the NETWORK (or STACK) port and check these ports for debris. Then, clear the fault by pressing the RESET button for one second. If the fault continues after these steps, the controller will require service.
How to troubleshoot an internal power fault on a Magnum Energy PT-100?
The PT controller has stopped working to protect itself because its internal power control circuitry reached its protection limits. You can try to fix this by pressing the RESET button for one second to clear the fault and turn the controller back on. However, if the fault persists, the controller likely has damaged or faulty components and will need to be repaired.
What does an internal phase fault mean on my Magnum Energy PT-100 Controller?
The PT controller has turned off to protect itself because one or more of the internal phases is faulty, or the phase signals are not in sync. Try pressing the RESET button for one second to clear the fault and turn the controller on. If the fault cannot be cleared, the controller may have damaged or faulty components and will require repair.
