EMMA managing a hybrid solar and wind system in Perth, Scotland.
This EMMA TP45 is installed alongside a 11kW Gaia wind turbine and 6kW of solar PV in Perth, Scotland. These work perfectly as a hybrid system with EMMA. The owner specifically wants to use all power produced by these renewable generators on site.
The Gaia installation is of note because it is an asynchronous wind turbine – meaning that it does not use inverters.
On this site, EMMA monitors each phase and sends any available excess power from the PV system and wind turbine to a 9kW three phase element in a 1000 litre buffer tank on site. When this reaches the desired temperature EMMA sends excess power to a swimming pool heater which also has a 9kW immersion. No energy is wasted in this install. The owner gets to use all the power produced by his generators onsite.
The owner has also set up a Lister engine with a 3kW generator which is also used for heating the pool with the electricity but also heats the buffer tank with a series of heat ex-changers on the exhaust of the engine. The engine is run on waste chip pan oil which has been filtered to the point where it could run a diesel car.
The ELITE is the latest addition to the EMMA product family. While we consider it to be the Elite of power diversion and monitoring it is in fact EMMA's little sibling or as we call it EMMA lite.FIND OUT MORE

EMMA with EC allows for installs to have a greater renewable output than the Max Export Capacity (MEC) on site by diverting excess energy to heat.FIND OUT MORE
