I understand it's permissible to install a domestic battery which is charged at off-peak rates (like an off-peak water heater) and has no associated PV installation. NSW has two off-peak tarriffs known as "controlled load" 1 and 2. CL-1 is used by domestic water heaters and (with my retailer in a regional area) is 25% cheaper per KwH, but the access charge is 7.7 cents/day vs. 107.47. Power is nominally supplied during off-peak evening periods (around 22:00 to 06:00) via a smart meter, though I'm sure I've seen the HWS heating during periods of high-solar output. I must get out the trusty spreadsheet to estimate the likely savings, or not. Against that, most users having PV panels with no battery say their power bills are zero or even in credit, which at first blush seems unlikely given the low feed-in tarriff. _David Lochrin_ _______________________________________________ Link mailing list [email protected] https://mailman.anu.edu.au/mailman/listinfo/link
