IoTaWatt is a very versatile tool. It can be configured for any power system worldwide – single or three-phase. That’s why it’s in use in dozens of countries on four continents. Selecting the appropriate bundle below, based on geographic area, 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 simply adding a CT to the inverter. For up to 12kW that’s usually a 50A split-core CT for $8.40. 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.

IoTaWatt Base Units are out of stock

Expect restock in 1-2 weeks (Nov 21 – Dec 1). Demand has soared while we are encountering the same supply chain issues as everyone else. Fortunately manufacturing was ramped up several months ago, all of the parts are now in New Hampshire and new units are being built as you read this.

UPDATE: Manufacturer is now quoting end of the week Dec 6-10. Waiting for confirmation. The good news is that the plant is 34 miles away so will have them the next day. Waiting for firm date later this week.
