The iSola is an innovative new technology that feeds your existing electrical geyser with two power sources ie. AC grid power and DC PV power. No need for backup batteries, the PV is directly fed into the geyser when available and essentially stored inside the geyser as heat energy.

The iSola does not feed your AC Element with DC power. DC is converted to a modified wave which is safe to use in the existing element and thermostat. This modified wave form enables the thermostat to switch power on and off as if it were normal AC power.

There is no need to replace the element or thermostat having the following benefits:

• Lowers installation cost
• No change to your existing geyser
• Easy installation
• Readily available spare parts
• Works on any generic water tank
• What options are available?
• SANS Compliant

Models Available:

• iSola STANDARD 2/3Kw (for 100/150L geyser) PV Panels: 3 x 500/545/575 Watt
• iSola MAX 2/4 Kw (for 200L geyser) PV Panels: 4 x 500/545/575 Watt

HYBRID CAPABILITY (Eskom Back up)

The STANDARD and MAX controllers can be installed with a additional timer and temperature sensor enabling you to switch your geyser between AC and DC (Eskom and Sun).

With eWeLink (Smart Home application) installed on your phone you can track your temperature, etc. With this app you can set timers (or manually) to switch to Eskom for back up (anywhere in South Africa – via WiFi).

MPPT

Efficient MPPT

All our models have MPPT [Wiki]. MPPT enables the Pi²R to extract power more efficiently out of the PV panels by adapting the intake power to the current weather conditions.

Advantages above traditional solar geysers:

• More aesthetically pleasing
• Water tank does not have to be outside on the roof
• Can switch off when water is warm enough
• No water loss due to overheating
• No circulating water or anti-freeze
• Less losses due to circulation
• Panels and geyser can be far apart
• No plumbing – no plumbing issues
• No maintenance
