Field notes
Battery Truth models storage against interval import and export data rather than relying on a quoted system size. Its demo includes a 6.6 kW solar household, a time-of-use tariff, two years of half-hourly readings, and quarterly bills. The site also distinguishes temporary modelling data from retained daily totals and results, while noting that real account connection has not been enabled.
