IoTaWatt is a very versatile tool. It can be configured for any power system, voltage or frequency – single or three-phase. That’s why it’s in use in dozens of countries on four continents. Selecting the appropriate bundle below makes it easy to start with the right basic components for your application and to build on it for additional monitoring.

Many other monitors offer a “solar” option. You won’t see that here because any of these bundles can monitor solar by just adding a CT to the inverter. For up to 12kW that’s usually a 50A split-core CT for $7.65. Same for monitoring EV charging or any other load.

The IoTaWatt base unit is made in the USA. It’s ETL certified to UL standards, FCC part B compliant, and also CE marked. All of the power supplies and AC transformers are UL Listed. The current transformers are UL or ETL recognized components that conform to the base unit listing specifications.

Sold out of V4 Base Units. It’s been a good run, with thousands sold, but the last remaining inventory have been sold. Since introduction of the V5, sales of the V4 have been less than 20% of units sold, so customers have self-selected the V5 going forward.

Pricing will be changing. Over the next week or so, there will be a new pricing structure to address the huge increase in cost of CTs, VTs, and components to make IoTaWatt Base Units. These are due to the 25% Trump Small Business Tax on top of the pre-existing 6.1% tariff on these commodities. There is no relief in sight. International customers should feel free to source these items direct from China.
