The benefit for a battery in a house or commercially is when it can provide KWS during times of no grid supply, and that situation is less than 1%, usually due to some form of natural disaster. If that is the requirement other factors need to be considered. We can expect to rely on the grid in most cases where an occasional outage does not present difficulties for most people.

The other factor to be considered is the charge and discharge cycle; charge during the lowest cost rates, and discharge during the highest rate times. If a battery is used at Peak KWS rate times it is ideal to charge during Lowest KWS rate times, or Night rate times, when there is no solar generation.

If a battery is used during Night rate times, it will need to be charged during Peak rate times which coincides with Solar generation. If Solar is also used to power the site, domestic or commercial, sufficient capacity is required to charge the battery and operate appliances as required, in such cases the Solar capacity may need to be doubled. It is possible to arrange some control system to manage battery charge times coincident with Solar capacity, but adverse weather conditions may be an added complication.

There is discussion around utilising battery storage, from EV’s or domestic installations as inputs to manage peak load conditions with “Time of Use” and “Dispatch Notification” controls, this is more an aggregation of multiple resources of Solar and Battery. While it is anticipated individuals may participate, it is unlikely there would be individual controls.

Super Capacitors

MyPowerStation is a roll-in solution that features everything required to add a storage system to a new or existing solar array. It is fully adaptable in a range of sizes. From households to institutions.

Sirius is a revolutionary product that stores energy using supercapacitors, rather than through a chemical composition. It is safer, and more efficient than any alternatives. Can be added to any existing system – micro or string inverters.
