5A MPPT 9V 12V 24V Solar Panel Regulator Controller Battery Charging Auto Switch
1w-100W 9V-28V is suitable 9V 12V 18V 24V solar panels to the batteries, nickel-cadmium, nickel hydrogen, lithium batteries (battery) charging, wind turbines solar street lamps
Input and output terminals are made of high-end switching power supply for high-frequency low-impedance electrolytic capacitors (LOW ESR), ensure that the output ripple. Can effectively filter out the switching power supply glitches.
Module parameters :
The modular nature: a real MPPT solar maximum power point tracking, automatic intelligent charge management, low power consumption
Input voltage: DC 8-28V input DC voltage. (Prohibition AC input)
Output voltage: DC 5-26V stepless transmission For lower output voltage, please contact the owner.
6V battery can be charged either 12 or 8.4V, 12.6V, 16.8V lithium battery
7.2V, 10.8V, 14.4V lithium iron phosphate battery
2-4 string lithium batteries, lithium iron phosphate charge management board
Output Current: 2A / 5A maximum charging current in two: A version 5A B version of A 2A 5A default shipping version
Charge indicator: Yes. Fast charging red light long bright red and blue lights flash alternately charged. Full automatic stop.
MPPT function: a. MPPT maximum power point automatic tracking, to maximize the full use of solar charging
Low pressure: 1V (as is the step-down voltage regulator, the input voltage is at least higher than the output 1V)
Low power consumption: Yes! Ultra-low pressure designed to achieve low power consumption and high efficiency, professional adaptation of solar panels
Operating temperature: Industrial grade (-40 ℃ to + 85 ℃)
Load regulation: ± 1%
Voltage regulation: ± 0.5%
Conversion efficiency: Max: 93% Peak: 95% for different lighting conditions vary.
Charging: automatic intelligent three-stage charging mode. Self-tracking solar power charge current automatically adjust the size
No-load current: 3MA even weak morning sunlight can easily start automatically, eliminating manual switch.
nput reverse polarity protection: Yes. Exclusively designed ultra-low dropout prevention MOS transistor reverse polarity protection, input reverse is not working.
Output reflux protection: Yes. Effectively prevent nocturnal reflux battery electric charge sheet!
Connection: There Terminals
mppt voltage: adjustable, MPPT solar modules in different voltage is different, even mppt voltage can not tune mppt solar controller, can be called mppt it? MPPT control technology using charge sheet charging efficiency ratio control scheme in general or a DC-DC step-down power MCU + PWM lift about 30%. Make full use of solar energy, and low-power operation. Reduce power loss! MPPT function can effectively prevent the solar panels so that the charging voltage is the battery slow slow death.
Note: The first charge in advance regulate the output voltage and please closely monitor the battery voltage to prevent overcharging! Do not unprotected lithium batteries!
Debugging method:
Step 1: Connect the solar cell, do not take the bottle to be charged, if the output voltage in step 2. If there is no transfer of small output counterclockwise slowly until the output voltage MPPT.
Step 2: counterclockwise transfer of small output voltage until the red and blue lights flashing, then coarse output voltage to a full cut-off voltage
Step 3: Access dead battery, and at the output string ammeter to monitor the charging current, MPPT trimming potentiometer until the charging current maximum.
Step 4: Access is just full of batteries, if the blue light is clockwise turn up the output voltage until the red light. Then transfer a small output voltage slowly counterclockwise until just blue lights, and then use a multimeter to measure to determine the cut-off voltage is correct to avoid overcharge!
ransfer methods instead of using the power supply of solar energy:
Step 1: The power supply was adjusted Solar MPPT voltage (such as 18V)
Step 2: The power supply connected to the input terminal, do not take the battery to be charged, if the output voltage is adjusted clockwise until no large MPPT voltage output. Then slowly counterclockwise until the transfer of small MPPT just have the output voltage.
Step 3: anti-clockwise turn down the output voltage until the red and blue lights flashing, then coarse output voltage to a full cut-off voltage
Step 4: Access is just full of batteries, if the blue light is clockwise turn up the output voltage until the red light. Then transfer a small output voltage slowly counterclockwise until just blue lights, and then use a multimeter to measure to determine the cut-off voltage is correct to avoid overcharge!
Charge Management board features:
1. Solar cell maximum power point tracking, the output current is greater than the solar panel current, real ultra-efficient MPPT, support 8-28V, 100W solar energy within large current charging with a solar panel recommended that each module) multiple modules connected in parallel to expand the charging current
2. The output voltage can be adjusted, CC-CW automatic control (can support single or multi-lithium batteries or lithium iron phosphate or lead-acid batteries, high-power LED, etc.)
3. A complete battery charge management
4. PWM Switching Frequency: 300KHz
Measuring resistance, low dropout perfect protection against reverse, reverse does not work, put an end to reverse damage to the charge sheet
Package included：
