The Sun-Sink storage can work independently of solar Pv by drawing grid power at times when it is less expensive to purchase and making it available for use when grid power is most expensive. Even if you live in a home unit it may be possible to draw power at off-peak rates and save it for use at peak times when electricity costs are at a premium. The storage unit needs only to be connected to an installed inverter in the premises and can be located in a laundry or even on a balcony to provide seem less power savings to the occupant. If you live in a multi unit complex it is possible for a co-coordinated roll out of Sun-Sink storage to not only reduce power costs for tenants, but also reduce body corporate electricity costs significantly. For home owners who are unable to utilize solar due to shade or other issues, time shifting electricity supplies can achieve of savings up to 40% on your average usage costs without any need to modify your usage patterns.
In bulk supply (body-corporate) schemes, the benefit of equipping each unit with a time shifting device can substantially reduce maximum demand charges which can make up as much as 50% of the buildings electricity costs.
Our Sun-Sink product is currently available in DC coupling mode only, our grid demand version designed for grid charging for time-of-use management is subject to approvals for AC power interface. This accessory will be available subject to demand.
