30A 12V/24V Auto Switch Mppt Solar Panel Battery Regulator Charge Controller(Black) - Intl

MPPT SOLAR CHARGE CONTROLLER

1. SAFETY
Full consideration to the safety of persons and property has been givenwhen designing the products. However the incorrect connection may cause thesystem breakdown or even safety accident. For your safety and benefits, thefollowing rules must be complied during the operation.
.Installation of this product shall be tinder the guidance of the professionalsin this field.
. Prevent this controller from water, humidity and insects, to avoidshort-circuit.
. Keep children and incapable persons away from the controller
. Keep the controller away from electrical heater, heating machine and otherhigh temperature electrical appliances; avoid the controller suffering frominsulation directly.
. Please check the rated voltage of solar panel, battery, and loads beforeconnection. 12V rated voltage is 12V, 24V rated voltage is 24V, 48V ratedvoltage is 48V.
. Make sure connections between positive and negative poles of Solar panels, Battery and Loads are correct.
. The diameter of connecting cable must be matched with the requirements of thecurrent. Do not use thinner diameter cable, the thinner diameter. The largerresistance, this will cause higher temperature and output power decreasing.
. The total rated current of solar panel and loads must be smaller than therated current of the controller.
. Components of system must be correctly and firmly connected. Prevent theterminals from oxidation and moldy, to avoid connection trouble.

2. FEATURES

. MPPT solar charge controller MPPT10-30:Compared with normal solar charge controller, this MPPT controller couldincrease efficiency by 10%-30%.
. This controller can charge and discharge at the same time.
. This MPPT controller has perfect SOC function, control charge current, andsupply power to the loads.

Function:

. Always keep the battery on fill voltage condition.
. Prevent the battery from over-charging.
. Prevent the battery from over-discharging.
. Prevent the battery from reverse charging to solar panels during nights.
. Reverse Polarity Protection for Battery
. Reverse Polarity Protection for Solar Panels
. When the battery voltage is low, the controller will automatically cut offthe load from the system. If the voltage of battery is back to normal and theload will restart working.
. Thunder protection
. According to the battery voltage grade, the controller can automatically setcharge-off voltage, the load-off voltage, the load- restore voltage. (Theparameter is default under 25℃ condition, locked by the CPU procedure, cannot adjust.)

. The controller will automaticallycompensate the temperature of the charging voltage according to the changes ofambient temperature.

3. CONNECTION

Connection Oder: battery cable → load cable → solar panel cable

Connection of battery: Connect the battery cable to the output terminal of the controller, pay attention to the positive and negative charges protect from contrary connecting or short circuit (the positive and negative charges come together). If it is correct, the corresponding battery power indicator (Overlow, Normal, Full) will be bright. Otherwise, Check the connection is correct or not.

Connection of load: Connect the load cable to the output terminal of the controller, pay attention to the positive and negative protect from contrary connecting, Otherwise, it may burn the appliance.

Connection of solar panel: Connect the solar panel cable to the output terminal of the controller, pay attention to the positive and negative charges protect from contrary connecting. If it is sunshine (PV array voltage greater than 10V), The charge indicator will be bright. Otherwise, check the cable connection.

Notes:

Do not use lamplight to charge the solar panel (lamplight is too weak tocharge)
DC power source to replace the solar panel will cause troubles to controller.

Choose the suitable wire which diametershould not be too small, please refer to the parameter.
