My nimh batteries are 12v 2700mah.
12v solar panel charger circuit.
A solar charger excellent for self sufficiency the intent behind this circuit should be to achieve a solar charger 13 6v supply with low price.
Thank you for the detailed information.
Best 12v battery solar charger.
The following wiring diagram shows that the two 12v 10a 120w solar panels connected in parallel will charge the two 12v 100ah parallel connected batteries as well as power up the ac load through batteries and inverter during the day in normal sunshine.
A solar panel will continue to charge to its open circuit voltage which is usually around 17v for panels used in 12v systems.
The post explains how to build a simple 12v solar charger circuit with boost converter capable of charging 12v battery from a 3v solar panel.

I am actually looking to build a solar charger to charge my nimh rechargeable batteries which will in turn run a dc stepper motor.
The above explained solar charger circuit using transistors and with auto cut offs can be used for any small scale solar controller applications such as for charging cellphone batteries or other forms of li ion batteries safely.
Best 12v battery solar charger panel typically put out about 13 6v to 17 0 volts use to charge 12v battery or to run any 12v devices.
During shading night when there is no generating power from solar panels the battery stored energy will be used as a backup power and it.
Found this page very useful.
12v 50w solar panel to charge a 12v 40ah lead acid battery.
Wiring pv panel to charge controller 12v battery 12vdc load.
In this circuit capacitor c1 protects from the static discharge.
Diode d1 protects from the reverse polarity.
The solar panels that i am using are two 6v panels with a power of 1 5w each.
20w 12v or 10w 6v vout range.
Keep in mind that ac load is not connected in this pv panel wiring tutorial which needs extra equipment such as ups and inverter to convert the solar panel and.
This is much too high for lead acid batteries and will cause excessive grid corrosion and pressure venting and rapid failure of the battery.
In this simple solar panel wiring tutorial we will show how to connect a solar panel to the solar charge controller battery and direct dc load according to the rating.
