12V-220V-DC-AC-System-With-Generator

12V / 220V DC/AC System with Generator

This system provides all the benefits of a combined Direct Current (DC) and Alternating Current (AC) system with the added benefit of a standby generator. This is perfect if you have some high demand appliances or your demand exceeds your solar generation ability. It also provides very good resilience for those cloudy winter days when the solar generation will be reduced.

12V-220V-DC-AC-System

12V / 220V DC/AC System

This system provides both Direct Current (DC) and Alternating Current (AC) electricity. This has several advantages in the DC lighting is more efficient, in the scenario you could power your lighting and water pump from the DC side and also run 220V appliances such as televisions and computers.

12/24V-Direct-Current-(DC)-System

12/24V Direct Current (DC) System

The first system is a Direct Current (DC) system that generates 12 or 24 volts only. This type of system is perfect for high efficiency lighting and a surprising number of 12v appliances. Traditionally all mobile homes and caravans operate on 12v electricity. A visit to any caravan outlet will reveal an amazing number of low voltage appliances from televisions to microwave ovens.

Learn-About-Backup-Generators-For-Off-Grid-Installations

Backup Generator AKA: The gas guzzler

Off-grid solar-electric systems can be sized to provide electricity during cloudy periods when the sun doesn’t shine. But sizing a system to cover a worst-case scenario, like several cloudy weeks during the winter, can result in a very large, expensive system that will rarely get used to its capacity. To spare your pocket, size the system moderately but include a backup generator to get through those occasional sunless stretches.Engine generators can be fueled with bio diesel, waste oils (Including WVO, WMO, Gear Oil) petroleum diesel,gasoline, or propane, depending on the design. These generators produce AC electricity that a battery charger (either stand-alone or incorporated into an inverter) converts to DC energy, which is combustion engines, generators tend to be loud and stinky but a well-designed solar-electric system will require running them only 20 to 100 hours a year.

Wood-Forge-Project-Going-Ahead

Previously I have mentioned a wonderful little project to supply off grid power to a Metal Casting Wood Forge Down the far south of England.

The new 140W Panel arrived today from the manufacturers. I am extremely impressed with the Solar PV Panels construction. Open circuit is 21.8V and will charge 2 x deep cycle SLA batteries at 12V. The Pure Sine Wave Inverter arrived late last week so I am currently contstructing the sub frame for the panel to be mounted on.

I'll be posting some pictures of the setup once it is installed at the forge some time soon.

BBC-Radio-Leeds-Steve-Bailey-Drive-Home-Live-Interview

2 Weeks ago I was contacted by BBC Radio Leeds (Steve Bailey). They had been looking with interest at all the work I have been doing relating to Off-Grid / Carbon Neutral Power production.

I was lucky enough to be interviewed by Steve Bailey on the Drive Home Spot at 5:30PM for 20 minutes. We spoke of the work I do providing Off-Grid power via Solar PV, Wind Turbine and Solar Heating, something we are all fast becoming experts in due to the ever increasing costs of Crude Oil. This effects everything in the modern world from Petrol & Diesel right down to the cost of grain, staple foods and transportation costs.

I hope some of you heard the program and enjoyed it as much as I did. I will be in Australia from Mid September 2008 for 5 weeks, I am going to visit family and also to make a decision as to weather or not to move out of the UK for good.

When I return Mid October Steve Bailey of BBC Radio Leeds has invited me back for another live interview to update him as to my decision on moving to Australia.
