6.0 Protections, Troubleshooting & Maintenance

6.1 Protections

·
PV Short Circuit
When PV short circuit occurs, the controller will stop charging. Clear it to resume
normal operation. PV input must not exceed 100V,otherwise the controller will be
damaged.
·
PV Over current
When charging current is much more than rating, the controller will disconnect solar
module(s). So eTracer may not work in the maximum power point if PV current
doesn't match with the current rating.
·
PV Overvoltage
If PV voltage is larger than maximum input open voltage 150V, PV will remain
disconnected and warn until the voltage falls safely below 145V. PV voltage cannot
be too high, otherwise it may damage the controller.
·
PV Polarity Reversed
Fully protection against PV reverse polarity, no damage to the controller will result.
Correct the miswire to resume normal operation.
·
Battery Polarity Reversed
Fully protection against battery reverse polarity, no damage to the controller will
result. Correct the miswire to resume normal operation.
·
Overheating Protection
If the temperature of the controller heat sinks exceeds 85C, the controller will
automatically start the overheating protection.
