![]() ![]() ![]() These switch-ins can be programmed to occur automatically. They can also maximise their use of ‘free’ energy by running optional loads when the demand is low, and the batteries are at 100%. Acting on information they found there Jackson chose to replace their convection heaters with infrared heaters – which require far less energy. For many people, powering their homes or small businesses using a small renewable energy system that is not connected to the electricity grid - called a stand-alone system - makes economic sense and appeals to their environmental values. Thanks to the Color Control GX – which controls the installation’s power harvest, storage and supply – system data can be viewed both locally and remotely via the Victron Remote Management platform VRM. This provides Off Grid Engineering with the ability to observe and make alterations to the system programming.Ī ‘History’ function stores comprehensive energy-use profiles. Off-Grid or Stand-Alone Renewable Energy Systems. They were in the habit of simply filling up their diesel tank every week with no information about when and where energy was being used. One of the features of the system that Jackson Civil Engineering are particularly excited about is that it can provide detailed information regarding energy usage. This would have decreased their reliance on the generator still further. If there had been more roof-space, Ian would have recommended installing twice the amount of PV – taking the total solar generation capability to 20kW instead of just under 10kW. Savings by end-of-contract are projected to be over £130k. Jackson were awarded a ten year contract which has seven years to run. The Quattro has a power-assist feature – if there is a spike in demand which would exceed the generator’s maximum output, the Quattro immediately supplies that demand from the batteries. Off-grid system also called standalone system or mini grid which can generate the power and run the appliances by itself. Primarily, the system which is not connected to the main electrical grid is term as off-grid PV system (Weis, 2013). Using a smaller generator near its peak output extends the life of the generator and is more fuel-efficient. Standalone or Off-Grid Systems The off-grid system term states the system not relating to the gird facility. Solar panels are what most people think first when they hear the term off-grid. Generator run-time has been reduced from 24hrs/day to 3½hrs/day …using a much smaller generator. We just need the right tools and technology to harness and capture it for our off-grid needs. Analysed after eleven months of operation they found they had made savings of £25k placing the project break-even point at 2½ years. The installation was completed in under 2 weeks. ![]()
