Coobee Solar Charge Controller 20A Solar Panel Charge Controller 12V 24V LCD Display Auto Charge Regulator with Dual USB Port Adjustable Parameter Timer

SPECIFICATIONS System Voltage: 12V/24V Auto Charge Current: 20A Max Input Power & Voltage:260W/12V system; 520W/24V system USB Output: Dual USB output, 5V/2.5A Float Charge: 14.2V (Defaul, adjustable) Discharge Reconnect voltage: 10.7V (Defaul, adjustable) Discharge Stop Voltage: 12.5V (Defaul, adjustable) Self-consume:<10mA Operating Temperature: -35?~+60? Size/Weight:134*70*30mm/160g Safety Instructions Charge Controller should connect in the order: 1)Battery array 2)Solar panels 3)DC load The disassembly sequence is contrary to the wiring order. Make sure batteries's voltage between 9V-15V for 12Volt system and 18V-30V for 24Volt system so that the Charger controller can recognize the normal battery type and system in first connection. Parameter Setting Rules?Floating voltage > Low voltage reconnect > Low voltagedischarge The solar controller will stop output when the battery under 10.7V(adjustable).TheLCD will be blank when the battery under 8V and it will re-output when the battery up to the 12.6V(adjustable). Install the Charger controller to the battery as close as possible to avoid voltage and power dropping caused by overlong wire and affect normal voltage judgment. Connect the inverter (DC / AC) to the battery. DO NOT connect to the solar controller. The LCD display has an error of 0.2 V- 0.3 V, but this is normal Attention: Please keep the controller and battery pack away from high temperature and humidity, and keep away from flammable and explosive materials. Please Keep the controller in a ventilated place when using it, do not cover the device or install it on the car. Do not open the heat sink of the solar controller without permission.
