60A MPPT Solar Charge Controller Warm Tips

  1. Solar controller link order: first connect to battery; then connect to PV array; finally connect to load appliance.
  2. Don't connect inverter, wind, alternator charger into the charge controller! Please connect the solar controller to the battery.
  3. If solar PV input voltage lower 3V or lower than batteries’ voltage. It may be appears to have been discontinued.
  4. Parameter Setting:Floating voltage > Low voltage reconnect > Low voltage discharge.
  5. When controller makes buzzing because the controller dissipate heat. It will be stop when temperature return to normal.
  6. Don't let the positive (+) and negative (-) terminals of the battery touch each other.

FAQ

1. Precautions before using a Easunpower MPPT 60A solar controller ?

Users should first connect the battery before connecting the solar panel for the solar controller to function properly.Otherwise, it may cause irreversible damage to the controller.

2. Why is there no voltage displayed after I connect the solar panel?

It may be caused by low voltage. When connecting the PV, it is necessary to ensure that the PV voltage is 1.5 times higher than the battery voltage.

3. Why does my controller display a current of Zero?

When the battery is in float charging state or the solar panel is damaged, the charging current is problly to be less than 1ah. When the charging current is less than 1Ah, the charging current is displayed as ZERO.

4. What is an MPPT charge controller, and how does it benefit my solar setup?

An MPPT (Maximum Power Point Tracking) charge controller optimizes the power output from your solar panels, increasing the efficiency of solar energy capture, especially in varying sunlight conditions.

5. Which battery types are compatible with this charge controller?

This controller is compatible with a variety of battery types, including lithium (LiFePO4), AGM, Gel, and flooded lead-acid batteries. Ensure that your battery type is supported for optimal charging.

6. How can I monitor the performance of this MPPT controller?

The controller features an LCD display that shows real-time data, including battery status, charging current, and solar input voltage.

7. What’s the difference between an MPPT and a PWM charge controller?

MPPT controllers are more efficient, particularly in low-light conditions, as they adjust the voltage to maximize power output from solar panels. PWM controllers are simpler and generally less efficient, making MPPT ideal for larger systems.

8. Is an MPPT too big?

There is a practical limit, if the solar array is too large then the power is just wasted, since the charge controller is always limiting the output. A typical recommendation is to limit the solar array to 110%-125% of the maximum controller rating.

9. Does an MPPT make a battery overcharge?

Easunpower solar charge controllers use maximum power point tracking (MPPT) technology which optimize solar production and control the battery charging voltage to prevent overcharging.

10. What does an MPPT do when the battery is charged to full?

When the battery voltage reaches a point where the battery charger decides that the battery is full, the charger will cut out, and stop drawing power from the MPPT controller. In other words, the battery charger will present a high impedance to the MPPT controller.

11. Can I connect an MPPT with an inverter directly?

No! MPPT solar charge controllers help to flow the current efficiently into your depleted battery. If we connect an MPPT solar charge controller directly to the inverter, your soalr system can get damaged, but if not damaged, there will be zero input in the inverter. So connecting MPPTs directly to the inverter is a bad idea!

12. How big of a MPPT solar charge controller do I need?

ou take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the soalr charge controller. For example, a 1000W solar array ÷ 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.

13. How do I set up the controller for a lithium battery?

To set up for a lithium battery, simply select the lithium option in the battery type settings on the controller. Consult the manual for exact steps to ensure compatibility with your lithium battery specifications.
