Different models of Cool Power's EMMA (Energy and Micro-generator Manager) are available to suit whatever size and type of micro-generator you have. Single Phase, Three Phase and Integrated Units (that replace the standard domestic electricity distribution board) are outlined below.
We are even using a smart-grid EMMA DSM unit to optimise the performance of a 90 year old restored water turbine micro-generator in Andover, UK (Details and photos (PDF, 2 pages))
The EMMA 15SP serves any micro-generator system up to 3.6 kW. For instance, it is ideal for using with a micro-generator (up to 3.6 kW) and a standard immersion heater (3 kW). It can also be used with two small storage heaters (1.5 kW each). The EMMA 15SP model is supplied with all domestic flatpacks or can be bought separately.
The EMMA 35SP is suitable for any micro-generator system from 3.6 kW to 8.4 kW. This makes it perfect for using with even the largest sized grid-connected single phase micro-generators permitted by ESB Networks under current regulations (6 kW).
An example use would be the EMMA 35SP with a 6 kW micro-generator and a circa 6 kW calorifier in a 500-1000 litre thermal reservoir.
EMMA TP is designed for any sites with three phase grid-connections, including the largest grid-connected three phase micro-generators permitted by ESB Networks under current regulations (11 kW). EMMA TP allows for the control of loads up to 75 kW.
A number of EMMA TP configurations are available so it can be matched to the size of your micro-generator. The modular nature of EMMA TP allows for the control of loads of up to 3.6 kW, up to 8.4 kW, up to 10 kW, up to 25 kW, up to 35 kW and up to 75 kW, depending on your needs. EMMA TP can be easily expanded as you increase the size of your system.
These units come complete with a fully functioning domestic distribution board and can be use in place of standard distribution boards. These are designed primarily for installation during construction but can also be used to replace old distribution boards.
All of the second generation EMMA units come with their own display screens that show exactly what is happening in real time. They also have the potential for use as sophisticated timeclock and temperature control devices. They can be used, for example, to ensure that particular temperature requirements are met during particular time periods in the most efficient way possible. This ensures that these temperature requirements will be met using power drawn from the grid only as and when necessary e.g during periods of low microgenerator output.
