The DIY Solar Power Monitor
Powersensor Solar + is a comprehensive home and solar energy monitoring system. It helps you get the most out of your solar panels by providing detailed insights not offered by solar inverters or electricity bills.
Easy Installation. It's the only solar energy monitor you can install yourself.
Realtime Updates. Get instant access to solar power production, self-consumption, and grid export.
Energy Insights. Uncover precisely how much power you use, produce, and export. Explore historical data by hour, day, week, or month.
Reduce Costs. With Powersensor's detailed cost tracking, you can optimise when you use energy.
Expandable. Add up to eight extra Plugs and Sensors to track and itemise key appliances.
The app includes a detailed and easy-to-follow set-up guide. You'll be up and running in about 15 minutes.
Check if You Have Single, 2 or 3 Phase Power
At your electricity meter-board or switch-board, take a look at the 'Main Switch.' You can verify your installation type by referring to the image below.
Single Phase (single-pole) main switch on the left vs. a 3 Phase (three-pole) main switch on the right. 2 Phase power is less common and has a two-pole switch.
How the Powersensor Solar Monitoring System Works
The Powersensor solar monitoring system has four main parts.
The Sensor, Optical Reader (three-phase only), Plug, and App.
The Sensors are wireless devices that you install at your meter-board and solar inverter. See the image gallery at the top of this page for some examples. They measure the magnetic field of electrical flow without directly contacting any wires.
The Optical Reader detects any digital electricity meter's pulse output (flashing red light). It helps to calibrate the primary sensor at three-phase sites only.
The Plug measures the power usage of a key appliance and helps calibrate the main sensor at single-phase sites. It also acts as a wireless 'gateway' relaying data from the sensors to the internet via your WiFi network.
The App provides instant access to your data, whether you're at home or away. The app includes both energy and cost tracking.

Frequently Asked Questions
What's included in the Powersensor Solar kit?
Depending on which kit you choose, you'll receive the following parts. The app will guide you through the installation process for your kit.
- Single Phase - 2 x Sensors, 1 x Plug
- 2 or 3 Phase - 2 x Sensors, 1 x Optical Reader & Bracket, 1 x Plug
You'll also receive:
- USB cables to recharge the sensors once every year or two.
- High-quality 3M Dual Lock velcro pads to secure the sensors in place.
- Printed instructions and a QR code to download the app.
How many extra plugs or sensors can I add?
You can add up to eight extra sensors or plugs to track individual appliances or loads.
I'm still unsure if I have Single, Two, or Three Phase power.
Please read our article on how to tell if you have three-phase power.
Can I access the app when I'm away from home?
Yes. You can check your energy usage from home, at the office, or anywhere in the world.
Does it work with multiple solar power inverters?
No. Please choose the Powersensor Energy solution if you have more than one solar inverter. Rather than tracking multiple inverters individually (which is not possible), it tracks the NET import and export of power from your main switch-board.
How often do the readings update?
The app's readings update every 30 seconds.
Is the Powersensor App free?
Yes. Your purchase of the device covers the cost of the app.
Can I download my data?
Yes. The app includes a data export function (to a .csv spreadsheet file). Data is stored half-hourly and includes kWh, peak kW, and cost values for energy from-Grid, to-Grid, Solar, and Net.
When is Powersensor NOT recommended?
There are a few situations where the Powersensor system will not be compatible with your setup. These are:
- Apartments or units - unless your main meter-board is fully accessible by you and within 10 metres of your home.
- Home battery systems. Powersensor hopes to add this functionality in the future.
-
3 Phase properties with multiple electricity meters. Single-phase sites with multiple meters are acceptable.
What other devices do you sell?
