Workers from Lumos PV Power Systems Ltd are able to install solar PV systems at domestic and commercial properties in Oxford as well as further afield within the Cotswolds.

However, if you are interested in utilising a solar PV system, you need to carefully consider how you should have it configured.

This includes thinking about how the solar panels ought to be connected to the battery storage system. Lumos installers can utilise AC (alternating current) or DC (direct current) coupling when implementing solar batteries; here are summaries of how these two coupling options differ.

AC Coupling

Otherwise known as a ‘grid interactive’ system, an AC-coupled system is where the battery storage system is connected to the electricity grid.

The grid and the solar panels would — in usual circumstances — both contribute towards charging the batteries. However, the solar panels would continue doing so even if a power cut leads the battery storage system to automatically disconnect from the grid.

Lumos can install an AC-coupled battery storage system for an existing solar panel array or in the process of putting in place and setting up a whole new solar panel.

DC Coupling

DC-coupled solar batteries are both cost-effective and time-effective for Lumos to install. This kind of system uses an inverter integrated directly with the battery.

This arrangement is known as a ‘hybrid’ one, and means that solar power can be stored in the battery before being released at a later time, such as at night. In short, the user is not required to use up solar energy straight after their solar PV system generates it.
