At the beginning of the day, as soon as power is generated by the solar array, the solar charger will measure the ambient temperature and use it to temperature-compensate the charge voltage. During the float stage, the solar charger will re-measure the ambient temperature and adjust the voltages accordingly.
8.11.11. Error 40 - PV Input failed to shutdown If the solar charger is unable to turn off the PV input, it will go into a safe mode in order to protect the battery from over-charging or having a high voltage on the battery terminals. In order to do that, the solar charger will stop charging and disconnect its own output.
A wiring or labelling mistake during the solar charger installation is possible. Always double-check the battery polarity before reconnecting the battery wires to the solar charger. Reverse battery polarity can potentially damage the solar charger, causing its internal fuse to blow for fail-safe protection.
1. The cable conductor resistance does not meet the requirements, causing the cable to generate heat during operation. 2. The cable selection type is improper, causing the conductor cross-section of the cable to be used to be too small, and an overload phenomenon occurs during operation.
8.5.5. PV voltage too high The PV voltage should always stay within the maximum rated limit of the solar charger, as indicated in its product name, type plate and Technical specifications. The solar charger can sustain damage based on the extent of the PV voltage height, and it's important to note that such damage is not covered by warranty.
Applying a higher battery voltage than configured in the solar charger (eg. 48V battery to a 12, 24 or 36V configured charger), and then connecting the PV array, can cause the protection to “mis-trigger”. Meaning that the charger sees an over-voltage, and as such assumes that there is an internal fault and then engages the latching protection.
