Plant owners in Germany for example can easily implement requirements from the German Renewable Energy Act (EEG 2012) and have new options: Plants below 30 kwp, for example, can be throttled at 70 %. With Smart Timing, the power from the photovoltaic plant can be consumed directly, and this saves hard cash, allowing customers to take rising electricity prices in stride. The SolarLog monitors the power production and current consumption and indicates when enough energy for selfconsumption is available. For investors with large solar plants, the SolarLog delivers the hardware and software to implement efficient and reliable Powermanagement. With very little effort, grid operators can be granted access to all of the control functions. 43

All devices offer the option to precisely control appliances via the SolarLog. Additional options to control appliances include networked smart plugs, a devices that fit on top of existing electrical outlets and the integrated relays on the SolarLog 1200 and

36 3 Energy Management The flexible linking system makes it possible to create different scenarios for a particular appliance which is to be turned on or off. Heat pumps, electrical appliances, motors and pumps are ideal devices to help maximize the amount of selfproduced power consumed. For example, you can create a heat pump profile with SolarLog that has various running times configured to ensure a certain amount of heat even during periods with little sun. To carry out this optimization, all you need to do is measure your consumption. The SolarLog 300 and 1200 Meter come with integrated power meters for 2 x 3 phases. Only single phases have to pass through the external current transformers (CT) which are connected to the SolarLog. The SolarLog measures every phase individually and delivers the corresponding value. Additionally, two electricity S 0 meters or supported RS485 meters can used to measure consumption. Daily summary with presentation of yield and power consumption balance, drawing down power (red), power production (yellow), consumed power (green). Presentation options In the display, the current power values are displayed and the amount of surplus power is calculated. This allows the operator to determine the ideal time for switching on external appliances. Depending on the amount of surplus, a Smiley emoticon indicates whether or not it makes sense to manually turn on appliances at a given point in time. If the power meter is configured as a consumption meter, an additional power balance dialog is available on the touch screen. 45

37 Feedin management Powermanagement makes it possible to temporarily reduce the amount of fedin power which is required in Germany since the German Renewable Energy Act of 2009 (EEG). The SolarLog software and hardware products cover the entire range of requirements for Powermanagement. The particular requirements depend on the size of the plant.

38 3 Energy Management Powermanagement up to 30 kwp Operators with a PV plant up to 30 kwp (German law at present) have a choice when it comes to power reduction. They can choose a remotely adjustable power reduction or a fixed reduction of 70 %. This fixed regulation is applied to 70 % of the power output from the installed module at the feeding point. The firmware of the SolarLog 300, 1200 and 2000 offers two versions to implement the fixed 70 % power reduction % fixed reduction With the fixed reduction, the inverter s power feed is limited to 70 % of the module s output. The SolarLog adjusts the inverter to 70 % to limit the maximum yield accordingly. However, yield losses from about 3 to 5 % are to be expected with this function.

39 2. Fixed reduction with the calculation of selfconsumption This function offers an innovative solution to minimize losses that result from the 70 % reduction. To carry out this function, the SolarLog only needs a power meter. The SolarLog calculates the amount of private consumption and the current amount of power being produced by the inverters. If the difference between the current production and consumption exceeds 70 % of the module s power output, the inverters are regulated accordingly. Optimization of the 70% reduction by selective consumption of selfproduced power to take rising electricity prices in stride SolarLog SolarLog TM Meter or Meter Inverter Continuous restriction of inverter power feed at 70% Selfconsumption Grid Example: A plant with 10 kwp has to be limited to a maximum output of 7 kwp with the 70 % reduction. If an appliance, such as a stove, that uses 600 watts of power is turned on, the inverter could also convert 7.6 kwp into AC power. Only 7 kwp is delivered to the feeding point. A SolarLog Meter or an additional meter such as an ISKRA meter (our recommendation) is needed to implement this function. 48

40 3 Energy Management 3. Simple Feedin Management for plants up to 100 kwp in Germany The requirement of simplified feedin management from the German Renewable Energy Act (EEG) has to be implemented for plants up to 100 kwp. The signal to reduce active power is generally sent via a Ripple Control Receiver. The SolarLog PM+ product line comes with an additional interface for potentialfree contacts. Up to two Ripple Control Receivers can be connected to this interface, one for power reduction and one for reactive power control. Reactive power can be conveniently controlled from the SolarLog and does not have to be entered for every individual inverter.
