Domestic hot water production control unit PR-SA

for photovoltaïc installationsstand-alone

Increasing self-consumption and reducing costs: Power Reducer SA is a stand-alone solution generating minimal impact, in terms of expense and difficulty of installation, for producing hot water by means of photovoltaic energy. Routing surplus solar power automatically to an electric water heater with storage tank, users can secure an immediate benefit which, in certain cases, can mean suspending the use of power from the grid for entire periods of the year. Power Reducer SA is suitable for all installations: it operates independently of the inverter and of the monitoring system installed. How it works Power Reducer SA is a completely stand-alone control device with a built-in energy meter that provides the facility of producing hot water without ever drawing power from the grid. Connected to a water heater / storage tank with an electric immersion element rated up to 3.0 kW, Power Reducer SA can deliver immediate savings. Power Reducer SA diverts surplus energy automatically (even just a few hundred Watts) without drawing from the grid. Measuring available energy by means of the current transformer (CT) installed on the meter line of the grid supply, the Power Reducer SA minimizes the power demand of the electric element in the water heater / hot water storage tank, consequently avoiding the need to draw electricity from the grid.
