AC Charging of lithium batteries with inverter in the loft.

Inverter and batteries installed on timber in the loft

George T., a customer from UK, completed a super-economical energy system that will enable him to store energy at a reduced price at night and re-use it during the day. The secret is actually the economy rate offered by the electricity supplier Octopus. The agreed rate is only 5p per kWh.

Having an expandable energy storage system is ideal for homeowners who wants to invest in batteries that will be charged with the energy they need. If the energy needs will increase in the future, lithium-ion batteries and especially US2000 from Pylontech, can be easily expanded by adding 2.4kWh modules.

More and more drivers are now planning to change to electric vehicles (EV) and UK has a clear target to reduce the carbon footprint even further. By 2030 the sale of diesel and petrol cars will be banned in the UK. It will be a fantastic green idea to have your own “fuel station” at home.

The diagram illustrates the clear paths of energy. The imported energy is with red arrow. The low cost energy that is withdrawn from the batteries or solar panels is with green arrow.

Adding more batteries homeowners will be able to charge their cars with low-cost electricity and use the stored energy to power up the entire household.

In the near future if there is a requirement to install solar panels, the inverter is ready to accept PV arrays of output 6000Watt (6kW). Average size 3 bedroom property has enough space for 8 solar panels 2840Watt.

What is required to make your own low cost electricity ?

  • A smart meter connected to the economy rate
  • Find the right deal with electricity providers
  • 1 square meter of free space in your loft, garage or utility room
  • 1 square meter of free wall for mounting the inverter.
Lithium Ion US2000 Batteries. A pile of 2 in parallel with total energy 4.8kWh.
Energy meters measures the power demand and sends data to the solar inverter
The energy meter measures the power demand from the incoming power supply and feeds data to the inverter. The inverter will regulate the power flow from solar and batteries.
Easy to read LCD screen on the hybrid 5kW inverter. The diagram illustrates the power flow from solar panels and batteries to the household.
