A practical comparison of three common meter paths for three-phase solar homes: IAMMETER WEM3080T, Eastron SDM630, and Chint DTSU666, with guidance on CT vs direct wiring, inverter compatibility, local data, Home Assistant, and import/export monitoring.
A practical guide to choosing between a P1 smart meter reader and a DIN-rail kWh meter for home energy monitoring, covering installation effort, data quality, solar import/export visibility, appliance metering, local APIs, Home Assistant, and long-term upgrade fit.
A practical decision guide for households deciding whether a whole-home energy monitor is worth buying, covering when smart meter data is enough, when circuit-level monitoring pays off, what features matter, and how to avoid overbuying.
A practical guide to choosing an energy meter when data access matters more than a polished app, covering local APIs, MQTT, Modbus, cloud exports, Home Assistant, sampling intervals, ownership risk, and the trade-offs between open meters and app-first monitoring systems.
A practical guide to deciding when a Wi-Fi energy meter is the better fit than a traditional DIN-rail Modbus meter, covering retrofit difficulty, local data access, solar monitoring, Home Assistant, three-phase panels, reliability, and the trade-offs that matter before installation.
A practical guide to deciding whether local energy data is worth the extra setup, covering privacy, reliability, solar and battery automation, Home Assistant, MQTT and local APIs, cloud-only monitors, and the buyer profiles that benefit most from keeping data close to the home or site.
A practical guide to the best upgrade path for households that want rooftop solar now and a home EV charger later, including which inverter and meter choices preserve flexibility, when prewiring is worth doing early, and how to avoid paying twice for switchboard, monitoring, or charger decisions.
A practical guide to choosing between a simpler string inverter setup and a more flexible solar system, including when low complexity is the smarter buy, when battery-ready or optimizer-heavy architectures earn their extra cost, and which future upgrades should change your decision before installation day.
A practical guide to what to check before buying a home EV charger when your electrical panel is already tight, including how to judge real charging need, when lower amperage is enough, when dynamic load management is worth paying for, and when a panel upgrade is still the cleaner answer.
A practical guide to choosing between cloud monitoring and local monitoring for a solar home, including what changes in remote access, data ownership, update speed, mixed-system flexibility, maintenance burden, and when a hybrid setup is the smarter long-term choice.
