I have added in the brown wire as brown line the diode as a blue line i have also added in the ve ve makers for the battery.
Circuit diagram of solar panel battery charger step 6 from below you can see the soldered connections how they run along the copper tracks.
The output voltage and current are regulated by adjusting the adjust pin of lm317 voltage regulator.
Before delving into the following concepts you can probably try this super easy solar battery charger which will ensure safe and guaranteed charging of a small 12v 7 ah battery through a small solar panel.
Any changes to be made.
I am using a 12v 2 7ah nimh battery and i am using 4 4 5v solar panels in series with a power rating of 1 5 w each panel and current rating of 0 334.
The charging current passes to lm317 voltage regulator through the diode d1.
That looks cool isn t it.
Solar panel output voltage is directly fed into lm317 positive regulator circuit and it is adjusted to give 12 volt output and battery connected to this bias through 3a 50v schottky diode.
