- The thermal portion will be added to my existing Surya plumbing circuit. That's been explained in an earlier posting on this website.
- The PV production cannot be added to the Grid, as we have reached our 4 kW limit, and must not risk changing the Feed-in-Tariff. It must be stored in a battery, and then used through an invertor.

At time of highest 'capture', there will also be 'demand', as the liquid pumps in the house will be working flat out, but these are low energy demand pumps. I shall also put additional demand onto the battery, such as the laptop, printer, broadband modem, hard disk, cordless phone. All useful in case of a power cut in the grid.
You have to get the balance right. If demand exceeds supply, then systems do not work, but worse than that, a fully flat lead-acid battery is difficult to restart.
