Dr wattsun E-monitoring
1. Dr WattSun
The Solar PV Specialist
3rd party Remote Monitoring
solution for distributed Solar systems
2. We are bringing Dr WattSun to India because the
existing solutions in the market have some serious issues
1. Inverter based Monitoring
Some inverters come with provision of internet connectivity and its data is
sent directly to the inverter company’s monitoring portal
• Portfolio Management not possible
• No standard data - different inverter brands have different
features/user interface/data options.
• Limited software features
• Auto/Remote relay control not possible without external controller
2. SCADA based Monitoring
Dedicated SCADA system is installed. Data collected at a central server can
be accessed on local software of through web portal, remotely.
• High Cost (not feasible for kW scale rooftop systems)
• Expertise required in installation (often subcontracted to 3rd parties)
• Frequent issues with software installation, User Interface and utility.
• Limited Portfolio Management features
3. Dr WattSun reduces the Cost, Time and
Complexity associated with the Solar Monitoring

Detects system malfunction or a sudden change in any parameter and immediately sends an alert E-mail and SMS
The message will specify the problem and its location in the plant
Single Window Remote Monitoring helps you identify the best system (Module + inverter) for your PV plants by comparing the data from present plants.
With us, you can control the relay directly through our website and mobile app (without actually going to the plant) in case of system malfunction.
[A relay is an electrically operated switch. This means you can turn the switch ON/OFF by using internet (just by clicking on the relay control option on our website or mobile app)].
