Meet iHot
Traditional solar hot water systems have long been a staple of Australian homes, but they come with undeniable drawbacks. Heavy, water-filled panels strain roof structures, complex plumbing loops require ongoing maintenance, and extreme weather can cause freezing or boiling issues.
The iHot Solar Hot Water Inverter offers a modern alternative. Rather than acting as a standard grid diverter or relying on old-school thermal plumbing, iHot connects a set of solar PV panels directly into your existing electric storage hot water tank. It turns standard sunlight directly into thermal heat, simply, safely, and cost-effectively.
What is iHot?
iHot is a compact, high-efficiency solar water heating inverter designed to use a small dedicated solar panel array for use with any existing storage hot water system.
Instead of routing power through your main household inverter, iHot takes DC power (up to 350VDC) directly from a dedicated array of solar PV panels and uses advanced Maximum Power Point Tracking (MPPT) technology to feed that energy into your standard heating element.
It requires no modification to your tank’s existing element or thermostat, making it an easy retrofit upgrade for standard electric storage tanks.
How iHot Outperforms Traditional Solar Thermal
For decades, solar hot water meant mounting a massive hot water tank and heavy copper collectors directly onto your roof. iHot replaces that heavy infrastructure with lightweight PV panels and standard electrical cables.
Key Benefits of the iHot System
1. Ultra-High Efficiency (Up to 99% MPPT)
Solar panels generate varying amounts of power depending on sunlight. iHot uses an MPPT controller with up to 99% efficiency. This ensures every single watt generated by your panels even on overcast days is extracted and squeezed directly into your hot water element.
2. Automatic Grid Backup & Off-Grid Ready
While iHot prioritises 100% free solar energy during the day, it also features integrated grid backup functionality. If heavy overcast weather persists, the system can draw from grid power overnight or during off-peak periods, ensuring your household never runs out of hot water. It is also completely compatible with off-grid properties.
3. Massive Bill Savings
Water heating makes up roughly 20% to 30% of a typical household’s energy bill. By generating your hot water directly from dedicated solar panels, a typical family can save up to $900 per year on electricity costs.
4. Simple, Lightweight Installation
Because iHot sits quietly next to your ground-mounted hot water tank and wires up like a standard electrical component, installation is quick and hassle-free. You don't need complex plumbing modifications or roof re-enforcements.
Upgrade Your Water Heating with iHot
Whether you're looking to cut your monthly power bills, lower your grid dependency, or replace a failing thermal solar setup, or a noisy Heat Pump the iHot inverter offers a smarter, lighter way to heat water.
