Solar-powered EV charger and Smart heat pump controller for residential use
Problem Statement
Homeowners increasingly need to integrate electric vehicle charging, heating systems, and other energy-consuming devices into a unified energy management system. This integration allows them to monitor usage patterns, optimize energy consumption, and control all connected devices through a single intuitive application.
Voice of customers
Homeowners
  • “If I’m generating solar power, I want to charge my EV with it—why waste energy by feeding it back to the grid?”
  • “I need to prioritize when to charge—automatically at peak solar times or when utility rates are lowest.”
  • “Heating and cooling are our biggest energy expenses—why can’t the system adjust based on solar availability?”
  • “It would be great if my heat pump could avoid running during peak pricing and use excess solar when available.”
  • “I don’t want to manage multiple apps for my solar, EV charger, heat pump and battery. I just want one system that works together.”
Installers / Technicians
  • “Homeowners keep asking if the EV charger can use solar power directly—right now we have to piece together different systems.”
  • “Commissioning gets tricky when the charger and PV system aren’t integrated. It would save time if they were part of one ecosystem.”
  • “Most HVAC systems don’t talk to solar or storage systems. We need an easy way to bridge those without deep rewiring.”
  • “We need better tools to visualize power flows—what’s going to the EV and heat pump what’s going to the grid, and what’s stored.”
