Request for Information and Quote for LiON Battery System Compatible with Sunny Island Controller / Inverter.
Solana Energy is under contract to design the Energy System of Casa Aguila, a new home under construction in San Diego County, California. The owner does not want any form of fossil-fuels to supply the home. Further, the owner wants the option in the future to disconnect from the local utility supplier, SDG&E.
The house is one of the very first in California to be constructed as a Passive Home with complete microgrid capability using no genset. The General Contractor is Alliance Green Builders. The owner has contracted with a marketing company, KNB Associates, to provide you, in exchange for a discount, a great opportunity to showcase your energy storage product and technology to specifiers including architects, engineers, and home developers. There will be staging opportunities to bring prospects to the home in Ramona, California. This is an optional marketing opportunity to consider for this RFI/RFQ. While running in parallel with the grid for the first few years, the battery array, sized at 40KWH, would provide ancillary power at all times when there is insufficient generation from the dual axis solar system (23KW) and the wind turbine (3.2KW). Power from the LiON bank is drawn by the Island Controller to supply the house load while preserving a margin of reserve in case of a grid outage. The SMA Island Controller represents the "brains" in deciding how much power and load to shed in the event the battery bank discharges below a safety threshold. While the grid is connected, the SMA Island Controller decides when to utilize the grid for the supply of power including when and if to use grid power to charge the battery bank or to allow the solar and wind generation to charge the battery bank. Parameters allow for optimizing these decisions. In the event of a grid outage or future disconnect from the the grid, the Sunny Island Controller is capable of production shedding to avert an over-supply of current on the network possibly damaging the battery bank. The owner will have a modern energy monitoring and appliance control system to manage loads and understand consumption. Therefore, it is expected that significant loads will be produced during the day and insignificant loads will be present during the night when self-generation is low or non-existent from the wind and solar resources.
