“enenowa”( + “hitonowa”)

Clear visualisation of multiple streams of energy flow

In the days when homes used only electricity purchased from energy companies, choosing the optimum tariff plan and saving usage of appliances were the only means to save cost. Nowadays PV generation, household storage batteries and EVs have come into the home, making it possible to generate electricity at home, store the surplus electricity, and use it at night. The energy flow has become more complicated.
“enenowa” displays the flow of electricity in such homes in an easy-to-understand manner. It also makes it easier to manage your home’s power supply, with convenient notification functions and the ability to start charging storage batteries in preparation for a power outage when a weather warning is issued for your area.
