Many Thanks for all of your Support

The campaign concluded last week with around 200% of my initial target raised. Thank you so much for your support. This gives me the opportunity to test the larger batches I have assembled and put some resources into products behind the product for automated testing.

The next steps will be completing QA of boards already assembled in Australia (which I believe will be sufficient to cover current backers) and design/testing of the DIN rail module. I have already tested the base power and high voltage sampling board as per a previous update. Here is a short video of isolation testing.

The measurement board will be a variation of the breakout board resized to fit the din rail. The front-end will be a standard Wemos D1 mini with OLED shield. Overall the design risk is low and uses components I have already tested and used in a different form factor. Onwards to the final delivery now.

Product Choices

$35

Energy Monitor FeatherWing

A hacker-friendly, low-voltage dev kit for the ATM90E26. Compatible with most Adafruit Feather-series boards and accessible via SPI or UART. Two can be stacked in SPI mode for grid + solar single-phase monitoring.


$70

Energy Monitor FeatherWing Kit

An Energy Monitor Featherwing with some essentials to get you going. The Adafruit Feather and a 100 A YHDC current clamp will be included as part of the kit. Voltage sampling transformer is the only other part the user has to supply.


$20

ATM90E26 Secondary Module for DIN Rail Use

Secondary module for the DIN Rail Energy Monitor above which will add another phase into the monitoring setup. Essentially the same as the breadboard version but with isolated SPI bus making it suitable for use with high-voltage inputs. This module can be used to measure a second phase or single phase solar output after the inverter. You can also use it to design your own isolated high-voltage monitoring system.
