Revolutionary Technology

The Elon® Smart

Solar PV water heating reinvented. The most affordable, efficient, and intelligent way to heat your water using the power of the sun — no inverter or battery required.

How It Works

Direct Solar PV to Geyser Connection

The Astra Smart Geyser system operates on a revolutionary principle: it enables direct current (DC) electricity produced by solar PV modules to be used directly for water heating using your existing geyser.

1
Solar Panels Capture Sunlight — Your roof-mounted panels convert sunlight to DC electricity.
2
Elon® Smart Manages Power — The controller optimises solar power to your geyser's heating element.
3
Hot Water, Zero Cost — Your water heats using free solar energy with automatic grid backup.

Key Features

Why The Elon® Smart Is Amazing

Cutting-edge technology that makes solar water heating simple, affordable, and incredibly efficient.

No Inverter Required

Cost Saver

Unlike traditional solar setups that need an inverter to convert DC to AC, the Elon® 100 bypasses this step entirely. It enables a direct DC-to-heating-element connection, reducing installation complexity, cost, and maintenance significantly.

No Battery Needed

Maintenance Free

Your geyser IS the battery. Water stores heat exceptionally well, so there's no need for expensive battery storage. The system heats water when the sun shines and keeps it hot for when you need it.

Off-Grid or Grid-Tied

Flexible

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

90%+ Efficiency

High Performance

Over 90% efficiency and only requires 20V to switch on under load. This means the Elon® 100 can start heating your geyser in lower-light conditions—cloud cover, winter days, earlier mornings, and later afternoons.

Smart App Control

Connected

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

Easy Installation

Quick Setup

No need to replace elements or install and wire multiple components. The Elon® 100 works with your existing geyser's AC heating element and thermostat, making installation straightforward and cost-effective.
