today I realised that my SmartSolar is charging my battery with up to 14.9V even if I have set the limit to 14.35. It worked very accurate since I installed the SmartSolar 100/20. At the moment I''m testing the charger before I connect Li-Ion batteries to it to make sure I stay away from the Voltage limits of the batteries for safety reasons.
These factors play a critical role in calculating the appropriate solar power setup to effectively charge a 9V battery. Battery Capacity: Battery capacity refers to the amount of charge a battery can hold, measured in milliamp-hours (mAh) or amp-hours (Ah). For example, a 9V battery with a capacity of 2000mAh means it can deliver 2000 milliamps

The Open Circuit Voltage (Voc) rating of a solar panel, on the other hand, indicates the voltage measured across the panel''s terminals under ideal conditions when no load is connected. For instance, as shown in the image above, my solar panel has a Voc of 22.5 Volts. This means that under Standard Testing Conditions, the panel should measure
What is the best way to charge a 9-volt battery? Similarly, a 9V battery may be charged with a 12V charger, as we demonstrate with Lithium-ion and NiMH batteries below. The 9V lithium-ion battery is made up of two 3.6V cells and has an 8.4V nominal voltage. A voltage source of 8.4V is required to securely recharge it.
There is nothing you can do with a 9 volt solar panel to charge a 9 volt battery. Get a 12 volt panel and proper charge controller. The circuit does not require 9V, and in particular, the audio amplifier chip is rated at up to 15V. That is a very strange circuit! It seems overly complex for the audio signal that it generates.
Also a 9 new 9 volt battery has more than 9 volts on the terminals. Your solar panel might charge a set of 4 c cells in series. BUT in all cases you need a charge controller to stop the battery from discharging into the solar panel when a cloud passes between the sun and the panel.
12V is a better option, because you can use readily available 12V gel cells, with reasonable capacity to driver speakers, etc. "12V" solar panels (18V peak, in fact, so you could use two of your 9V panels in series instead) and charge controllers are also readily available, and cheap. here is a picture of the circuit. Is the above possible?
In order to regulate the voltage from the solar panel normally a voltage regulator circuit is used in between the solar panel output and the battery input. This circuit makes sure that the voltage from the solar panel never exceeds the safe value required by the battery for charging.
This voltage if fed to the battery for charging can cause harm and unnecessary heating of the battery and the associated electronics; therefore can be dangerous to the whole system. In order to regulate the voltage from the solar panel normally a voltage regulator circuit is used in between the solar panel output and the battery input.
Meaning, even during adverse conditions when the sun rays are not sharp or optimum, the solar panel still should be able to generate a voltage more than say 12 volts which may be the battery voltage under charge.
