DC Fuses and how to size them
DC Fuses and how to size them.What is a Fuse?A fuse is an electrical safety device. It protects an electrical circuit against high currents. The fuse is placed in the supply cable to an electrical device. As soon as current flows through the fuse that is higher than its current rating, for a certain amount of time, the fuse will blow. Once the fuse has blown, no more current will flow into the circuit.Higher than expected current situations can occur when...

Lithium batteries are cheap!! Comparing LiFePO4 with Lead-Acid
(Read more about Lithium batteries here) People often claim that Lithium (LiFePO4) batteries are expensive, and although initial costs are higher, Lithium batteries are cheaper over a longer period. In this article, we will try and compare batteries that use Lithium Iron Phosphate (LiFePO4) chemistry with Lead-Acid batteries, in terms of capacity, longevity and price over an extended period of time. We will conclude that LiFePO4 batteries are about 40% cheaper in the long run, next to having a range of other benefits. We...
How to choose your Lithium battery
How to choose your Lithium Battery: A Lithium battery is often the most expensive element in a solar installation, and as a battery is a long term investment, it is important to take into account all aspects of a battery before buying. There are a number of parameters that are important to consider when buying batteries, for example: Voltage and capacity charge / discharge rate (C-rate) Depth of Discharge (DoD%) Life span, warranty and (local) back-up support Expandability Mounting other Voltage and...
