The single most important part of constructing an off grid solar system is sizing the battery bank. This is because during the day, solar panels … Read More

Sometimes a battery won’t start your device and you might feel frustrated, but remember: it wasn’t “bad luck,” it was because the battery self-discharged. That … Read More

All batteries are inefficient. Charging up any kind of storage system result in inefficiencies. These include losses due to voltage, heat, and chemical resistance. These … Read More

A battery are really just a bunch of cells, each one containing an ideal voltage source and a secret resistor. As soon as you use … Read More

How many times will your battery pack be able to move energy around and last? How long? Datasheets include a cycle life rating as a … Read More

The battery depth of discharge calculator turns one of the most misunderstood specs into a clear number. This one clears up a confusing spec. Depth … Read More

The second is a quick health check: You read the voltage on your battery and determine its state of charge. A calculator plots that one … Read More

When most people begin designing their battery pack, they knows what voltage they want, maybe twenty-four volts for a solar shed, or forty-eight volts for … Read More

Running in parallel mean that you can extend your battery life without increasing system voltage. This is simple enough, yet many novices will mistake parallel … Read More

The usual method for constructing a higher-voltage pack with battery cells are to wire them in series. That’s when you connect the positive terminal of … Read More
