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.

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.

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.

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.

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.

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

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.

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.

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

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.

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!

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.

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.
