Compare the whole bill using when you actually consume and export electricity. Cheap overnight units may be offset by a higher daytime rate, standing charge or less attractive export terms. Test realistic schedules and include any equipment losses. A tariff that suits an EV owner who can charge overnight may not suit a household with heavy evening demand.
Join the discussion: Which loads can you move, and do you have half-hourly consumption data?
Suggested next step: Request a combined tariff and system-cost comparison before buying additional equipment.
