DC-DC Adjustable Step up / Step down Power Converter Module XL6009 ( XL6009)
DSN6009 4A is a high-performance step-up switching current (BOOST) module used to step up a lower supply voltage to a higher output voltage. The module uses the second generation of high-frequency switching technology XL6009E1 core chip performance than the first generation technology LM2577. XL6009 boost module at a lower cost, superior performance, LM2577 module is about to be eliminated.

● Wide input voltage 3V ~ 32V, optimum operating voltage range is 5 ~ 32V;
● Wide Output voltage 5V ~ 35V;
● Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
● high switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz)

MPPT Solar Panel Regulator Controller Battery Charging 9V 12V 24V Auto Switch 5A ( mppt)
Is suitable for stepping down solar panels to 9V 12V 24V batteries 
 
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.
 
 
Charge indicator: Yes. Full automatic stop.
 
Low pressure: 1V (as is the step-down voltage regulator, the input voltage is at least higher than the output 1V)
 
Operating temperature: Industrial grade (-40 C to + 85 C)
 
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.
  
Note: The first charge in advance regulate the output voltage and please closely monitor the battery voltage to prevent overcharging! Do not charge 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 on the MPPT is high enough to engage the regulator.
 
Step 2: counterclockwise rotation of the pot will increase the output voltage until the indicator light red and the blue light flashes.
 
Step 3: Connect battery, and attach an ammeter to monitor the charging current, turn the MPPT trimming potentiometer until the charging current is at maximum.
 
Step 4: To adjust the output voltage maximum, connect a fully charged battery, if the blue light is on turn the Pot clockwise to up the output voltage until the red light turns on. Then turn the output voltage  down slowly (counterclockwise) until just blue light just turns on, and then use a multimeter to measure to determine the cut-off voltage is correct to avoid overcharging.
 
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!
