SOLAR PV HEATING
With advances in technology solar water heating systems have become more and more efficient.
After years of research and testing of various systems on offer , we can now offer the best system available.
The Pi²R Micro (formerly Geyserobot) PV heating system transforms your existing electric geyser into a solar geyser without all the added on solar collectors, insulated connecting piping, pumps and controllers.
The system consists of a solar PV panel array (3 to 5 panels), sized to match the capacity of your geyser, PV panel protection fuses and the Pi²R electronic unit with MPPT solar controller for maximum efficiency
By connecting the Pi²R Micro unit to your existing or new geyser, hot water can be generated more efficiently and conveniently than with conventional water heating systems.
Typical problems associated with conventional systems are eliminated with the Pi²R system
HOW IT WORKS
The Pi²R Micro functions as a specialized priority controller that enables PV Direct current (DC) (inverted to a modified sine wave) power to be used to power to the heating element of a standard electric geyser without the need to replace the element or geyser .Electrical connection is done by connecting the PV panels to the PV panel input on the Pi²R Micro controller and the 220V grid supply to the grid input on the Pi²R Micro Thereby providing the option of having grid backup in the event of bad weather or at night. The system will function normally on solar power if no grid is available.
The grid power is controlled by a separate geyser timer which means you are never short of hot water.
The unit corporates MPPT technology to maximise solar power
Advantages of Solar PV heating over conventional thermal solar heating,
2) Standard geyser can be used.
From Sept 2018 all geysers manufactured in SA have to comply with new SABS insulation requirements.
Therefore they are insulated with at least 55mm thick insulation, similar to existing solar geysers
2) Very low maintenance
No regular anti-freeze replacement required
No external piping or pump required
No moving parts
No freeze damage possible
Not susceptible to scaling and calcification
3) Performance
Much better performance under cloudy or misty weather conditions
Not affected by low ambient temps (flat plate collectors)
PV panels have 20 year lifetime warranty
No overheating (evacuated tube collectors)
4) Installation simplicity
PV panels do not have to be installed close to the geyser, allowing optimal positioning of panels. Ideal for Multistory buildings
