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)…
The size of the fuse that you use between your battery and inverter will depend on: The amount of current (Amps) that you’d like the inverter to be able to pull from the battery. The amount of current that the…
There are 3 variables that determine how thick a battery wire should be: The maximum desired voltage drop, which should not exceed 3%. The thicker the cable, the more efficient it’s going to be. The maximum amount of current (in…
Undersizing your wires can lead to unwanted power and energy losses and potential safety risks. And, since copper wires are expensive, you also don’t want to oversize your wires too much. Below you’ll find a calculator that will help you…
In this article, you’ll find a tool that determines the wire size in AWG and mm² that you need to connect your battery to the inverter for you. If you’re interested in how the tool works or would like to…
Unlike circuit breakers, if a fuse blows you’ll have to replace it. And since replacing parts every other day is the last you need, you’ll have to size your fuse in a way that it only blows if your system…
The size of the inverter that you need will mainly depend on 2 factors: The power usage and type of appliances you’re trying to run on the inverter. The specs of your battery bank. In this article, I explain how…
Assuming you want to charge the battery on a daily basis, there are a couple of factors that determine the amount of solar power needed to charge a 100Ah battery: The amount of energy (in Watt-hours) that you take out…
There are a few factors that determine how long it would take to charge a 100Ah battery with a 200W solar panel. In this article, I thoroughly explain these factors, and I provide a few steps that you can take…
There are a couple of factors that determine how long a 100Ah battery lasts: The energy consumption of the devices you’re trying to run. The type of the 100Ah battery and how much of its capacity is actually usable. After…
This article explains in detail how you can determine the amount of time for which you can run a 400W appliance on a 100Ah battery (both lithium or lead-acid). Before I get into it, there are a couple of variables…
In this article, I discuss the amount of time that a 100ah battery could run an appliance that requires 100 watts of power. As you’ll come to find out after reading this article, this comes down to 2 simple steps:…
