In this circuit the solar panel charges up a 3 cell nimh battery 3 6 v.
Simple solar panel circuit diagram.
Each spring i gather solar lights my neighbors tossed in the garbage after the lights have stopped working.
This solar panel ll give an output of max of 3v at 150ma.
Battery bank if off grid or standalone system 4.
The ones that only need minor repairs i repair and the ones that need major work i strip for parts and reverse engineer the circuit boards.
This circuit requires only a single ni cd rechargeable battery to light up the white led for more than five hours depending upon the ampere hour ah capacity of the battery.
However there are two potential problems with attaching a panel directly to a battery.
Between the two is a reverse blocking diode.
Dividing by 50 depth of discharge as you choose flooded that is 18000 0 5 36000wh or divde by 0 8 if for agm batteries that is 18000 0 8 22500wh.
Solar panel the back of the solar panel is shown in image.
The circuit design is extremely straightforward and may be understood with the following points.
This will quite happily charge a battery.

Step up transformer output stage pv solar inverter circuit diagram.
Basically that is 1500w 12 18000wh.
I have marked the ve side by adding black small dots on that side.
I am not sure why you said 2pcs of 120ah12v battries in series.
A simple solar panel voltage regulator circuit may be witnessed in the following diagram the given switch may be used for selecting a battery charging option or directly driving the inverter through the panel.
This one way valve allows current to flow from the solar panel to the battery but does not allow current to flow backwards out of the battery through the solar panel.
On the solar panel in center of left side right side you ll see a very small panel of smooth meta this is the ve ve terminals.

A simple solar wiring circuit with a blocking diode to prevent reverse current flow.
When sunlight falls on the solar cell during daytime the solar cell charges the rechargeable battery and turns led1 off.
Circuit diagram of solar garden light.
The first is that at night electricity can leak back into the panel which will slowly discharge the battery.
