An off-grid solar system must have all the necessary equipment to generate, supply and store solar energy onsite. Off-grid solar systems are also referred to as standalone solar power systems, as they operate without a connection to any external power source. They are made up of 12 volt solar panels (or modules) that can be used individually or combined into a single array. The solar panels use a solar charge controller to send power to charge solar batteries and a solar inverter to convert direct current (DC), which the solar panel generates, to useable alternating current (AC). Off-grid solar systems are ideal for remote rural areas and applications where power sources are either impractical or unavailable.

Solar cables are a combination of several insulated wires wrapped in an outer jacket. They are used to interconnect solar panels and other components of an off-grid solar system. They can withstand high temperatures, high UV radiation and all types of weather. Solar cables vary in diameter depending on the number of wires they contain and can be classified into three different types: DC solar cables, solar DC main cables and solar AC connection cables. DC solar cables are used within PV solar panels. String DC solar cables are used to interconnect solar panels. Main DC cables are large power cables that connect the positive and negative cables from the generator junction box to the central inverter. AC connection cables connect the solar power inverter to the protection equipment and the electrical grid.

How Solar Power Works in Industrial Applications

A basic solar setup includes:

Solar panels. The solar panel is going to absorb sunlight and convert that sunlight into energy.
Charge controllers. The charge controller is going to direct the energy that's absorbed by the solar panel to specific locations.
Batteries. A battery stores energy that is absorbed by the solar panel when it is not being used by the electrical load.
Inverters. An inverter takes DC power and converts it to AC power for use in homes or businesses.

The solar panel is absorbs sunlight and converts that sunlight into energy, in this case, DC power. That energy is going to be transferred over to the charge controller, which dictates where that energy actually goes. The charge controller is going to be wired to both the battery and it's also going to be wired to an electrical load. The charge controller will monitor the energy that is coming off of the solar panel and determine where that power is needed. For instance, if power is needed for an electrical load, it will send power in that direction. If there's no power that's needed for that electrical load, it will send power to the battery to store for later use. In the case where there is no need for power at the electrical load and the battery is full, the charge controller will dissipate that energy in the form of heat. In other applications, an inverter may be used in a solar setup. The inverter works by drawing energy, DC power, from the solar panel. It converts that energy into AC power, which can then be used in homes and businesses.
