How It Works

From smart geyser control to solar-powered hot water — getting started is easy. Here's how the system comes together.

1

Direct Solar PV Connection

The Astra Smart Geyser system connects solar photovoltaic (PV) panels directly to the geyser's heating element via our Smart Thermostat. This allows the solar energy to heat the water without any intermediary components or plumbing changes, making the system simple and efficient.

2

No Inverter Required

Unlike traditional solar setups that need an inverter to convert DC (direct current) into AC (alternating current), the Astra Smart Geyser system bypasses this step. It directs the DC energy direct to the geyser, reducing installation complexity, cost, and maintenance.

3

Off-Grid or Grid-Tied

The system can operate entirely off-grid if the solar array supplies sufficient energy for hot water needs. Alternatively, it can be connected to the electrical grid to provide backup power when solar energy is insufficient, always ensuring reliable hot water supply.

4

Smart Monitoring & Control

Integrated with a smart app, the Astra Smart Geyser System allows real-time monitoring of water temperature, energy usage, and overall performance. Users can also control and optimize the system remotely for maximum efficiency.
