Deciding on which alternative power systems to install in your home to beat load shedding is not a simple matter. Two electrical engineers explain what to look out for. | News24_Business

Long-Term Joint European Union - African Union Research and Innovation Partnership on Renewable EnergyThe way the charger is designed resembles the sort of system needed for domestic power cut solutions. So, we're able to answer a few questions for those who feel overwhelmed by the options. Our full and detailed instructions for designing a load shedding system will be available online soon.This is a key component of any alternative power system.

To reduce both the upfront capital cost and operational expenditure, you need to decide what is essential. Lights? Your washing machine? The stove and electric kettle? Then you need to make sure they are as energy efficient as possible before you size the backup system. For example, old incandescent lights use ten times more energy than LED lights do.Why do I need batteries for my system?

To overcome this problem, energy is stored in the batteries. This provides a more stable source of power which responds to demand during load shedding.Battery capacity is specified as kWh or Ah . This determines the amount of energy it can supply. A battery with a capacity of 5kWh can theoretically supply 5kW for an hour. But if a lithium battery is discharged beyond 20% of its capacity, it loses capacity and ages faster. A 5kWh battery therefore has an effective capacity of only 4kWh.
