What is a Fuse?First of all, let's try to understand what is fuse is for. 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. If a current flows through the fuse that is higher than its rating, the fuse will blow, and no more current will flow. This is what the fuse is supposed to do, to protect the device. Whatever the issue...

Batteries, Parallel, Series -

  At the heart of any solar PV system sits the battery bank; the battery bank can be either a single or multiple batteries connected to each other. Batteries are connected to each other in order to increase:- the battery voltage (in Volts, V), or- the battery capacity (in Ampere hours, Ah), or- both capacity and voltage.(Power = Volts x Ampere, or W = V x A). You can connect batteries either in series or in parallel. The following happens when batteries...

CoC, Installation, Safety -

Once your solar PV or backup system has been installed, it’s important to ensure that a Certificate of Compliance (CoC) is issued. Basically, this document checks that the electrician who performed the installation has complied with the rules and regulations that are in place to assure a safe installation.

Batteries, C-rate, Lithium -

Are you certain you have the right battery size in relation to your inverter? Follow the steps below to check your battery size (We will only focus on Lithium LiFePO4 batteries in this tutorial). First of all, find all the technical specifications or data-sheets of your equipment, and then follow these steps:Step 1: Determine the capacity of your inverter in kW (kiloWatt).Step 2: Determine the capacity of your battery in kWh and Ah.Step 3: Determine the C-Rate of your battery. Step 1: Determine the capacity of your inverter in kW (kiloWatt)....
