Protection

  • PV Over Current
    The controller will limit battery charging current to the Maximum Battery Current rating. Therefore an over-sized solar array will not operate at peak power.
  • PV Short Circuit
    When PV short circuit is powered on or PV input is short circuit on low-power, the controller will stop charging. Clear it to resume normal operation.
    Electric Warning Icon WARNING: The controller may be damaged, when PV input is short
    circuit on high-power.
  • PV Reverse Polarit
    The PV can be reversely connected with a controller when:
  • Only the PV is connected with the controller;
  • The battery is positively connected, and the open-circuit voltage of the PV is lower than 85V(This requirement is only for Tracer26/39/5210BP).
    Electric Warning Icon WARNING: Controller will be damaged when the PV array straight
    polarity and the actual operation power of the PV array is 1.5 times greater than the rated charge power!
  • Battery Reverse Polarity
    When the PV is not connecting or connecting reversed, fully protection against battery reverse polarity, correct the wire connection to resume normal operation.
    Electric Warning Icon WARNING: Controller will be damaged when the PV connection is
    correct and battery connection reversed!
  • Battery Over Voltage
    When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage, the controller will stop charging the battery to protect the battery from being over charged to break down
  • Battery Over Discharge
    When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage, the controller will stop discharging the battery to protect the battery from being over discharged to break down
  • Battery Overheating
    The controller detects the environment temperature through the external temperature sensor. If the environment temperature exceeds 65 ºC, the controller will automatically start the overheating protection to stop working, and recover below 55 ºC.
  • Lithium battery Low Temperature
    The temperature sensor is less than the low temperature value, Lithium battery stop charging/discharging. It is higher than the low temperature value, Lithium battery start charging/discharging.
  • Load Overload
    If the load current exceeds the maximum load current rating 1.05 times, the controller will disconnect the load. Overloading must be cleared up through reducing the load and restarting controller
  • Load Short Circuit
    Load will be switched off when load short circuit (≥4 times rated current) happens. Controller will automatically attempt to reconnect load for 5 times. If short circuit protection still exist after controller’s 5 times attempts, user have to clear short circuit ,then restart the controller or wait for one night-day cycle (night time>3 hours)
  • Temperature sensor break down
    If the temperature sensor short-circuited or damaged, the controller will be charging  or discharging at the default temperature 25 ºC to prevent the battery damaged from overcharging or over discharged.
  • High Voltage Transients
    The controller is protected against small high voltage transients. In lightning prone areas, additional external suppression is recommended.

Troubleshooting

Faults

Possible reasons

Troubleshooting

LED Charging indicator turn off during daytime when sunshine falls on PV modules properly

 PV array disconnection

Confirm that PV and battery wire connections are correct and tight

 

 

No LED indicator

Battery voltage maybe less than 8.5V

Measure battery voltage with the multi-meter. Min.8.5V can start up the controller

Battery LED indicator green fast Flashing

 Battery over voltage

Check if battery voltage is higher than OVD, and disconnect the PV

 Battery LED indicator red

Battery over discharged

When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load will recover

Battery LED indicator red flashing

 Battery Overheating

The controller will automatically turn the system off. But while the temperature decline to be below 50ºC, the controller will resume.

 

 

Load is not output

Load Overload

①Please reduce the number of electric equipments. ②Restart the controller. ③wait for one night-day cycle (night time>3 hours).

 Load Short Circuit

①Check carefully loads connection, clear the fault. ②Restart the controller. ③wait for one night-day cycle (night time>3 hours).

①When it is overload or short circuit, the load have 5 times auto-recovery  output function, which each times delay respectively 5s, 10s, 15s, 20s, 25s.

Disclaimer

This warranty does not apply under the following conditions:

FAQS

Would the unit be damaged if the battery polarity is reversed?

It is required to connect the battery first, if the battery polarity is reversed in this step, the controller has the protection and would not be damaged. But if the user connects the PV first and then, unfortunately, connects the battery polarity reversed, the controller would be damaged. This is caused by lithium battery characteristics.

Can the lithium battery type be chosen via the LCD and button on the controller?

Yes, the TracerAN series 10-40A charge controller (softwareSV200 or above version ) supports choosing lithium battery type via LCD. But WiFi/Bluetooth module or PC is required if the user wants to customize the voltage setpoints.

Can I set Max. charge current?

No such feature, the only way to limit the Max. charge current is to connect fewer solar panels.

Is this a three stage charger?

An essential setting that is often not available…

What is the operating high temp?

The manual gives an operational ambient temperature range of -25C to 45C, and a storage temperature range of -35C to 80C; the manual also says that if you’re operating outside the permissible ambient range, you need to derate the capacity in service (also, below -20C the LCD panel won’t display).

Can the 4210 model be paired in parallel with the same controller to increase capacity, like the 6415 can (6415 can be connected in up to a set of 8)?

Yes, it can. You can connect two or four 4210AN charge controller to the batteries bank in parallel, but do not share PV Panels. Dedicate a number of PV panels to each controller (Any mppt controller must have a separate array of solar panels).

Does this charge controller cause any amateur radio RFI or noise problems?

Yes to measurable rfi . No to it being a problem. N3SBX. If it were to become a problem just turn it off for weak signal work or build a filter

Why is 99% answers to how many 100w could be on 40a mppt wrong? why manufacturer says depends on actual amps from panels?

It depends on if you are charging 12 volt batteries or a 24 volt battery bank

Are these stackable?

You can connect two or four same Tracer AN charge controller modle to the batteries bank in parallel, but do not share PV Panels. Dedicate a number of PV panels to each controller.

Can you mount this controller so it lies on its side (horizontally on its long-thin side?)

As long it has airflow thru the fins , it should be fine . That is just my guess. 

Can this be used for Si02 batteries?

It may be possible. You will definitely have to contact EPEVER directly though. The specifications
for this line of controllers calls out Flooded, Gel, AGM, Li (FePo4), and user.

Is this temank or epever? Description has name as temank. Everything else syates epever.

This is an Epever

Do you need wi fi for this charge controller?

No. All functions are controlled by the remote display.

Can you insert a 4 gauge wire into the PV contacts? 

some of the connectors yes but not all

40A says 6awg for power terminals. I have 10 awg coming from solar panels, so do I connect the 10awg to 6awg prior to connecting to unit?

Not necessary! This means that the controller has input terminals that can handle 6awg sized wires

Will the tracer (20 amp) work on AGM batts?

From the manual: “MPPT Charge controller is compatible with Lead-acid batteries, GEL/AGM and Lithium batteries. (AGM battery setting same as GEL parameters, or more accurate parameters follow battery factory advice by User type ) Four load control modes: manual mode, light ON/OFF, light On+ Timer and test mode.”

My 4210AN with 3 panels in parallel putting out upto 33.5 volts does not seem capable of charging the 24v lifepo4 past 26.73v. Should it charge to 28?

You need to adjust the voltage you need go to settings and fix.
