Charging nimh batteries with solar panel.

I used a 100w solar panel to charge the 40ah battery. First i used the battery to power the lamp and it dropped to 8v. Connect the wires from the controller to the solar panel. You now have the complete design for your own solar charger.

I haven t tested it too extensively and it s. The problem now is that the battery is quickly draining dropping to 8v after 2 hrs of supplying power to the 24w led lamp. It is essentially the rule of the thumb for this procedure. I actually tested the panel myself and found that in the best case with 90 000 lux full sun the max voltage was 5 2 v corresponding to a max current of 157 ma.

Solar aa aaa rechargeable batteries charger for 1 2v aa aaa nimh nicd 9v battery with 2watt solar panel portable backup for 1 2v ni mh ni cd of solar powered lights and household battery 4 3 out of 5 stars 66. There are two main types of controllers in the market which include on off and pulse width module pwm. This is pretty simple and you don t need much. Match up the male and female connectors with the opposite ones coming away from the solar panel and snap the mc4 connectors into place.

The solar panel is rated at 1 w with a max load voltage of 6 4 v and the product page is here. Measure power into nimh batteries connect solar panel to pack of 4 nimh aa2 and measure the voltage and current at each step where applicable. The slightly lower voltage is not surprising because the solar charger was designed to end the charge cycle 30mv under max voltage. Solar aa nimh battery charger step 1.

Assemble the solar cell. Here we put the solar power supply together. The solar charger batteries had an average voltage of 1274mv and the duracell charger batteries had an average voltage of 1295mv. Do not use li ion batteries for this activity.

I think the charging works fine because from 8v the circuit was able to charge the battery to 13v. The battery capacity is 2450 mah with a nominal 1 2 v per cell and the datasheet is here. Once you ve attached the input wires to the charge connector you should have 2 loose wires each ending in an mc4 connector.
