How do Batteries Work?
Why is a battery bank necessary? Because an off-grid system does not allow you to store electricity easily and economically. There are other ways to store electricity but they are more expensive.

Photovoltaic System Grounding
Grounding is used to dissipate electrical energy safely when faults occur. This is the third pin on your extension cord plug which allows electricity to flow when system insulation fails.
Inverter Output Voltage
When purchasing an inverter, important considerations are the unit's electrical rating and the option of a "sine wave" or "modified square wave" model.
Here's what to check when selecting an inverter:
How to Choose Energy Efficient Small Appliances
The Energy Guide program was created to assist in the rating of "white goods", but what about smaller items and electronics which have no such label program?
Understanding Energy Guide Labels
Frankly, it’s not normal to carry around an energy meter when you’re shopping for electrical appliances.
Why an Energy Efficient Appliance?
There aren’t many people who would be content with a home that is not equipped with major electrical appliances, entertainment systems and computers. It isn’t wrong to have and enjoy a large-screen TV (unless you watch it the whole day!) or air conditioning. Using the energy to run the equipment is not the issue. The issue is purchasing inefficient models and, worse still, employing polluting and non-renewable resources to run them.
Energy Efficient Lighting
The incandescent light bulb is one of the inventions that has impacted our lives most. Before Thomas Edison’s discovery of electricity in 1879, it was pointless staying up after sundown.
Fluorescent Lighting Types
Compact Fluorescent Lamps
Large Area and Free Lighting
Large-Area Exterior Lighting
Understanding Battery Capacity
As you cannot see electricity, it is hard to confirm the exact amount of energy available in a battery bank.
