HotPV™ inverter.
Leading the way in off-grid solar hot water.
Downsize your power bill.
A big chunk of your power bill is usually from heating your water. Have a read and see how we came up with our unique and patented system to cut down your power bill and use your roof to do the work.
Why our inverters are the best for solar hot water.
A hot water cylinder draws a fixed rate of power to heat the water. It will draw from both the regular solar PV (photovoltaic) system and the grid to make up the power it needs to heat the water. For example: a 3 kW water cylinder will need to draw 3 kW of power to heat the water.
Conventional solar hot water heating early in the morning.
Every time your cylinder is on, and your solar PV system isn’t producing 3 kW, it will draw the difference from the grid. This can happen at any time of the day.
For example, during parts of the day, such as the early morning, the sunlight intensity is only enough to generate maybe 10% of what it takes to drive your cylinder’s element. So if your cylinder turns on at that time, a conventional solar PV system can only supply a small amount of power generated from the solar system, the rest of the power coming from the grid.
So essentially, only 10% of your hot water was heated by your system!
This is not solar water heating…
So we designed something great…
To ensure your solar system’s energy is put to good use in your home, we designed and patented the Hot PV™ inverter to only use the power generated from your solar system.
No other system does this.
With one of our Hot PV™ systems installed, you can sit back and relax, knowing your hot water is 100% solar!
HotPV™ inverter drawing power from your solar system exclusively.
Let’s break it down a bit more.
When your hot water cylinder needs heating, it will draw a fixed power rate until it is up to temperature, regardless of what your solar system is generating. If you have, let’s say, a 3 kW cylinder, it will draw a total of 3 kW of power. It could start at any time of the day, including when you first turn on the hot tap in your bathroom.
During the day, your solar system may not be generating 3 kW (for example, when clouds pass over or when the sun is not as bright in the morning or evening). So, if your solar system isn’t generating enough solar power, the additional power needed to reach a total of 3 kW will come from the grid instead.
Now, the majority of us are not home during the day, ironically when the solar system is performing at its best. So any power generated and not being used in the home is exported to the grid.
When you export power into the grid, your power company may pay you around 7 cents per kWh (kilowatt hour) of exported power.
But if you look on your power bill, you may be paying 19 to 40 cents per kWh.
So why not use the power you generate to reduce your monthly power bill?
Our unique patented VOV™ Variable Output Voltage configuration incorporated into the Hot PV™ inverter means the element in your hot water cylinder draws energy, but at no fixed voltage.
In this way, your water can be heated without drawing from the grid.
So say goodbye to grid-powered hot water!
