juta 30a 12v24v 2013 new mppt solar charge controller

Functions

instruction

1

maximum power point tracking

Adopting DC/DC converting technology and MCU technology to realize the maximum output of the solar panels

2

battery reversed connection protection

Battery polarity connecting to the controller reversely (under the condition not connecting solar panels) will not cause damage to controller. It can work normally after connecting right.

3

Anti-battery reverse discharge

When solar panels voltage is less than battery voltage, the battery will not charge to the solar panels array.

4

Anti-solar panels reverse connection

Solar panels array polarity connecting to the controller reversely will not cause damage to controller. It can work normally after connecting right

5

three-stage charge control

BulkAbsorptionFloat

6

float charging voltage adjustable

The users can adjust the float charging voltage within a certain scope.

7

temperature compensation for float charging voltage

Referring to the current battery temperature, take 25°C as a benchmark, the controller will compensate the float charging voltage by -4mV/Cell/°C. For 12V battery, compensation voltage U=(t-25)*6*(-0.004)V;For 24V battery, compensation voltage U=(t-25)*12*(-0.004)V;For 48V battery, compensation voltage U=(t-25)*24*(-0.004)V

8

Elevating charging voltage adjustable

The users can adjust the elevating charging voltage within a certain scope

9

solar panel input deviated from maximum power point

When solar panel input power is over the acceptable power for the controller, the controller will make the solar panel work deviated from the maximum power to prevent itself damaged. So the controller charges the battery by rated current.

10

internal overheating protection

When the internal temperature sensor detects excessive temperature, the controller will stop working to prevent it being damaged. It will resume working again when the internal temperature drops to a certain degree.

11

temperature controlling fan

When the internal temperature sensor detects the temperature exceeding a certain degree, the controller will start the cooling fan until the temperature drops to a certain degree.

12

panel over voltage protection

When the input voltage of the solar panels exceeds the rated voltage, the controller will start protection automatically and stop working until the input voltage resumes back to the normal scope.

13

remote controlling function

This optional function can make it possible to view and set the parameters of the system on PC.
