Hi everyone,
So i've been working on a circuit thats powered by solar and I have attach my schematic below. Okay so im pretty much new to the circuits an I have a background in wiring so I understand the basics. Lets jump into what i have,
Parts List
* DC12V 10W Solar Panel W/ USB Port Car Chargers For 12V-Battery Accessories Tool
* W1209 12V -50-110°C Digital Thermostat Temperature Control Switch Sensor + Case
* 4S 40A BMS 12v - 16v Heatsink Kit Li-ion Lithium Battery Charger Balance
* 18650 Battery Charging 4 BAY Cell Holder PCB Solder With Wire Lead
* 4x 18650 Battery 3.7v 3300mAh
* 120mm Fan 12v 1.6amp
Okay so with the parts above I sketched my circuit on a piece of notepad paper below. Now the problem I am having is after connecting all the components everything is operational up too the 12v relay on the W1209. When the parameter is met the relay wont engage. After taking a look at each component I found that the output voltage on the BMS was only 4 volts not 12v as I anticipated. Alright so I figured that i could throw on a DC to DC converter. Below is the part i bought,
* DZS Elec XL6009 DC - DC Booster Converter Module 3V - 32V to 5V-35v 4A Adjustable Step-up Voltage Regulator 5v 9v 12v 24v Power Supply Module
Last but not lease the second attach picture is the updated schematic with the booster converter. Last problem the highest output voltage I was able to get was 5v not enough to engage the relay still. Im at a loss now so any input would be great thanks for reading.
