How to choose the correct voltage for your products:
Basic principle:
(1) The solar panel voltage is best to be 1.5times higher than the storage battery, in order to fully charge the
battery, such as:
3.7V Lithium Battery ===== 3.7*1.5=5.55V. =====> The optium voltage for solar panel charging this lithium
battery is 5.5V, you can choose 6V. Voltage lower than 5V is not a good idea for fast charging;
12V Lead acid battery ==== 12V*1.5=18V ====> The optium voltage for solar panel is 18V, 17.5V is also
OK. But voltage lower than 17V will not be a good idea for fast charging.
(2) The voltage of solar panel is not the higher, the better, because during our R&D, we must consider the
charging current, and the battery protection. If the charging voltage is too high, the battery might be
damaged. And when the voltage is too high, the charging current would be weak, and the charging speed
would become too slow.
3.7V Lithium Battery ===== The solar panel voltage better not be higher than 6V.
12V Lead acid battery ===== The solar panel voltage better not be higher than 18V, because of the above
two reasons.
