hi devonscdevonsc said:Hi, do you guys mind explaining a little about this?
What are the consequences of applying a solar panel which has the output voltage of 20V to a 6V sealed lead acid battery for charging purposes?
Will doing so reduce the life-time of the battery?
Thanks in advance
very true but devon is talking about a single solar panel , which doesnt have the current to push the battery that far..If the solar panels have the capability of taking the charge voltage above 7.2 to 7.35 volts the battery can be overcharged.
devonsc said:I was trying to know if there would be any negative consequences to the battery if I were to apply a...for example, a 20V solar panel to charge a 6V SLA battery.
devonsc said:I do not have any of the mentioned parameters in-hand, Nigel. It was just a question that I suddenly thought of:
Just like, why do we need a buck converter when we have proper overcharge protection? So, for instance, a 6V 3AH battery being charged by a solar panel that has the output of 20V, 40mA charging current
"Why do we need a buck converter?" as in, we will still be able to perform proper charging even though my solar panel outputs a very very high output voltage with 40mA charging current.
Like the mentioned example, charging the 6V battery after stepping down the output voltage of the solar panel to a level of...say, 10V better than not having the output of the solar panel being stepped-down?
so did I......!!! :roll:I suggested a LONG!! time ago, feeding the panel directly to the battery, with a reverse blocking diode, if your panel can only supply a maximum of 40mA it's NEVER going to overcharge anything!.
