this is my first solar system,
145w, 24v panels
two 12v gel batteries working at 24v, 40ah each
pwm controller
300w inverter.
During the first days of use the batteries showed 27v as the floating voltage, during the days afterwards
this voltage increased to 28, and even 29v. I'm a bit concerned that this number might be too high. ?
the controller is a cheap chinese pwm controller with an LCD and temperature compensation, it doesn't show the temperature so I wouldn't be surprised if it doesn't have
a temperature sensor.
thank you!
