While the question “How many batteries do I need for my refrigerator?” lacks a one-size-fits-all answer, sizing a battery bank for your refrigerator is a straightforward process when you consider the following factors: The energy consumption of your refrigerator. The desired duration for which the battery bank should…
Running your refrigerator on solar power is quite feasible since fridges consume a relatively low amount of energy. However, it’s important to note that relying solely on solar panels won’t be sufficient to make this project a reality. To run a refrigerator on solar power, you would need…
So, you have a 12 Volt battery and a refrigerator, and you’re wondering “how long will the battery run the refrigerator?“. Now, due to the many factors involved (ambient temperature, usage, age, type, and size of the refrigerator, etc..), there are no general or 100% accurate answers to…
In a solar system, a battery bank has one important job, and that is to offset 100% of your energy usage. So naturally, when sizing a battery bank for your solar system, your energy usage, among other things, should be taken into consideration. If sized improperly, the battery…
To find the proper wire and fuse (or circuit breaker) sizes for your 3000 Watt inverter, you’ll need to calculate the maximum amp draw of the inverter. This maximum amp draw will generally depend on 2 factors: The efficiency of your inverter. The lowest battery voltage at which…
The amount of current (Amps) that a 1500 Watt inverter draws will mainly depend on the voltage of the battery bank (12V, 24V, or 48V), and the power usage (Watts) of the AC load. However, the wires and over-current protection devices (fuses and circuit breakers) used for the…
The maximum amount of Current (Amps) that a 2000 watt inverter is capable of drawing from the battery will mainly depend on 2 factors: The conversion efficiency of the inverter The voltage rating of the battery bank And in order to size the wires and the fuse (or…
In this article, I discuss the amount of Current (Amps) that a 1000 Watt inverter is capable of pulling from the battery and explain how to use the voltage of your battery bank and the efficiency of your inverter to determine this amount of current. I also discuss…
Watts (Power), Watt-hours (Energy), Amps (Current), Amp-hours (Charge), and Volts (Potential) are the units used to measure electricity, and they are often confused and ununderstood. After reading this quick article, you’ll learn about what these units represent in a battery, and you’ll also learn about concepts like charge…
Do I need a fuse between charge controller and battery? The answer is yes, you do need a fuse between your charge controller and battery bank. Should an overcurrent occur, you would want to have an overcurrent protection device (OCPD) placed between your charge controller and battery. An…
