Commentary: It looks like the magic quantity is around 3.Three volts. Under that you do not have important charging, above that you just do. A lithium iron phosphate battery doesn’t care if it is never fully charged, so if all you might have obtainable is 3.3 volts and you don’t thoughts the loss in capability you could possibly use the 3.Three volts. This opens up new chance for a simple but very long life backup battery in 3.3 volt systems.

Overcharge prevention4: A totally charged battery cannot take in additional energy. If the input energy to the battery is not managed, the voltage in the battery will get too excessive, which can cause a small explosion, stress hundreds, or shut off the inverter. Stopping overcharge of the battery or voltage drop is regulated by the cost controller and is an important operate of a charge controller. That is often carried out by switching the current absolutely off or on in a controller or via Pulse Width Modulation (PWM) to regulate voltage and battery cost.

I’ve investigated a bank of brand new and really-expensive sealed GEL cell batteries that were completely destroyed in a single day of overcharging. Due to this fact, if you’re planning to cost sealed AGM or GEL batteries, ensure to pick a photo voltaic charge controller having charging voltage settings for the kind of batteries you might be utilizing.

– wiring the photo voltaic charge controller to the battery financial institution and panels correctly.

– The controller display will mild up if the power is detected

– Hold the Menu button for seconds to coming into setting menu

– You will see the charge current (PV to Battery)

– Long Press the Menu Button to entering Batter Kind Selection

– Controller will auto detect the battery voltage

– Setting the float Charge Voltage,absorption charge voltage, low voltage cutoff worth, low voltage restoration value according to the battery consumer manual.

– set discharge value for DC load (if have)

– the charge controller will start the cost course of instally.
