I have a CMTP02-30A solar charge controller. When I connect it to a 24Volts battery (I.e., 2 Nos 12Volts 100AH batteries), the load light comes on green, and the battery light, all the 3 leds, comes on red in full. I discharge the battery completely until the inverter goes off by itself yet the 3 leds remains on but the solar panel indicator ...
If the battery is fully charged and you have a sunny day the LED should light up. You can even power the solar panel from a powerful torch or lamp by shining it onto the panel. Try experimenting by attempting to light the LED with the battery alone, or with the solar panel alone. And now we come to making your own battery charger.
Below is the solderless version. Connect the RED POSITIVE terminal of the solar panel to the NEGATIVE leg of the battery holder. Use the extra wire supplied to connect the POSITIVE end of the battery holder to the longer of the two legs of the LED. The longer leg of an LED is always connected to the positive side of the circuit.
Below is the circuit diagram for it. The solar cells positive terminal is connected through the diode to the positive terminal of the 1.2V battery. If the voltage of the solar cell drops below 1.4 volts then with the 0.2V the blocking diode takes there wont be enough potential to charge the 1.2V battery.
The longer leg of an LED is always connected to the positive side of the circuit. Then connect the NEGATIVE wire of the solar panel to the other LED leg. If the battery is fully charged and you have a sunny day the LED should light up. You can even power the solar panel from a powerful torch or lamp by shining it onto the panel.
To double the current output you need to connect the solar panels in parallel. Connect the positive terminal of one panel to the positive terminal of the other panel and also connect the negative of one to the negative of the other. This will give you a max rating of 3V at 300ma.
In order to double the voltage you need to join two solar panels in series. i.e. you need to connect the negative terminal of one solar panel to a positive terminal of the other solar panel. This will then leave you with a positive terminal from one panel and a negative terminal from the other to connect your wires to.

I attempted repair on a Renogy Rover 30 charge controller. I was changing out the batteries, failed to follow my written checklist, and disconnected the charge controller B4 disabling the solar panel. I was working in my barn with only 1 overhead light but apparently it was enough panel voltage to fry the circuit. I tested all of the fuses and ...
Here is few years old SilverCrest USB power pack with solar charger that stopper charging a smart phone. Because changing the charging cable did not help and the charging connector felt a little loose, it seems that the power pack is to blame here.

The generic Kw12x0 PWM Solar Charge Controller is a rather inexpensive piece of equipment but it doesn''t do a terrible job of being a basic solar charge controller. On the whole, it behaves as one may expect – protecting the battery from excessive voltage and overdischarge, with an integrated dusk timer function and USB outputs.
The optimized charging process facilitated by MPPT controllers also contributes to improved battery life. Furthermore, these controllers exhibit superior performance in challenging conditions such as cold weather or partial panel shading, making them versatile across various environments.

They are the solar panel voltage, the solar panel current, the solar panel power, and then the fourth value is the digital potentiometer value, and it is a seven-bit value that ranges from 0 to 127. That digital potentiometer is what sets the voltage of the solar panel. For the load, I''m going to be charging a large lead-acid battery. Right now, the battery is not connected to …

When you match the battery to the solar cell all you need for a charging circuit is a diode. To charge the high capacity of a NiCad battery or battery pack it is recommended to charge the battery at the rate listed on the battery label. But when you don''t have these instructions follow the C/10 charging rate.
