Can a 12V battery be charged with a PWM controller?
I have a 12V battery linked to my solar panels. In the middle I have a PWM charge controller, that is configured by default to charge the battery if Voltage if lower than 14.8. At night, battery goes down to ~13.8V. (Which I think is the voltage of the full battery) - with no added voltage from solar panels. Is it safe ?
What voltage should a solar battery be charged to?
Check the battery datasheet for proper voltages that are exactly correct for your battery. Otherwise use safe values. I have a commercial solar battery charger that by default overcharges the battery once per month to 15 volts to equalize the cells. Otherwise it charges it to 14 volts. These voltages can be changed from the user interface.
How much voltage does a 12V LiFeP04 battery need?
It requires more voltage than the “fully charged” state to reach that level. This would be the 14.4 - 14.8 (or thereabouts) your charger is utilizing. I think 13.8 or so is fully charged for a 12V LiFeP04 battery, so that drop back would be normal. As long as the discharge curve is as expected, it doesn’t sound like anything to worry over.
Can a 12 volt battery be charged with a regulated power supply?
Equipment designed to work with 12 volts DC from a regulated power supply, on the other hand, may be more sensitive. If you set any of the charging voltages lower than recommended by your battery manufacturer, you will reduce the life of the battery, possibly by a large amount.
How much battery do I need to run a 3000-watt inverter?
You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.
How do I calculate the battery capacity of a solar inverter?
Related Post: Solar Panel Calculator For Battery To calculate the battery capacity for your inverter use this formula Inverter capacity (W)*Runtime (hrs)/solar system voltage = Battery Size*1.15 Multiply the result by 2 for lead-acid type battery, for lithium battery type it would stay the same Example
