3 THE VISION THAT DRIVES US TODAY 3

4 THE WORLD OF 24 HOURS OF SUN 4

5 THE WAY TO 24 HOURS OF SUN Fronius has been designing the future of our energy supply for over 20 years. Over a million PV systems are already producing solar power with Fronius technology, each of which represents another step towards 24 hours of sun.

6 THE NEXT STEP TOWARDS 24 HOURS OF SUN: THE FRONIUS PRIMO Why are Fronius SnapINverters the next step towards 24 hours of sun? / Fronius SnapINverters not only impress with their ability to generate solar energy efficiently and reliably, but they also have all the integrated functions for the intelligent consumption and distribution of energy. / Fronius SnapINverters reduce the balance-of-system costs, thus helping solar energy to become competitive on the global energy market. 6

7 Requirements facing String Inverters 7

8 REQUIREMENTS FACING THE STRING INVERTERS OF TOMORROW / Increasing demands placed on system design / The significance of self-consumption systems in the domestic and commercial sectors is growing all the time orienting solar modules in various directions dramatically increases the self-consumption rate / Different module orientations and/or roof structures often cause partial shading / Higher generator output per unit area leads to smaller gaps between the rows of modules and causes temporary shading of the lower row / Short installation times and simple system planning mean that strings of differing lengths are connected directly to the inverter Requirement 1: Maximum flexibility in system design 8

9 REQUIREMENTS FACING THE STRING INVERTERS OF TOMORROW / Increasing demands placed on IT / The selective controlling of consumers is necessary to maximise the self-consumption rate / System monitoring is often carried out by third-party suppliers / Data is no longer stored locally, but on the internet / Customers want to keep a close eye on their system data on the move as well using smartphones or tablets / Effective energy management requires a central monitoring system and a simple way of integrating the PV system into the building automation system / The PV system also needs to be integrated with the control centres to facilitate control by the grid operator Requirement 2: Maximum flexibility in interfaces and protocols 9

10 REQUIREMENTS FACING THE STRING INVERTERS OF TOMORROW / Market demands placed on photovoltaics are changing rapidly / New national and international communication standards demand new software protocols / The requirements surrounding the remote control of PV systems by the local grid operator are increasing all the time / New safety rules demand completely new inverter functions, such as arc detection / The growing significance of self-consumption leads to new approaches towards systems and applications in photovoltaics Requirement 3: Future-proof thanks to easy expansion and adaptation options 10

11 Fronius Primo 11

12 FRONIUS PRIMO OVERVIEW / Single-phase transformerless inverter with power categories from 3.0 to 8.2 kva / Premium indoor and outdoor inverter / For installing indoors and in unsheltered outdoor locations (IP 65) / Communications package integrated as standard / Energy management / 2x energy management (relays, digital output) / Connection of third-party devices using JSON or Modbus / Connection of Fronius Smart Meter via Modbus RTU / USB, WLAN, etc. / SuperFlex Design across all power categories / For easy, flexible design / Dynamic Peak Manager / New MPP tracker for optimum adjustment 12

13 Fronius Primo Maximum flexibility in system design 13

14 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN: SUPERFLEX DESIGN / Extremely wide MPP voltage range from 200 to 800 V DC (80 V U dc min ) 14 / Permits string lengths of 4-24 solar modules (6" cells) / Feed-in beginning at 80 V / High system voltage of 1000 V DC / 2 MPP trackers with high current capacity / For unbeatable flexibility in system dimensioning / No power limitation power distribution from 0 100% per input possible / Can be overdimensioned / Can be dimensioned to up to 150% Pn / Suitable for all systems / For optimum system design on roofs with different orientations (e.g. east/west-facing systems), with or without shading / Optimum system design with strings of unequal lengths (e.g. on roofs of differing sizes)

15 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN: SUPERFLEX DESIGN / Example: DC performance per MPP tracker with Fronius Primo / P AC/NOM = 5 kw / P DC/MAX on MPPT 1 = 5 kw (100%) / P DC/MAX on MPPT 2 = 5 kw (100%) / Design options / Full power to tracker A / Full power to tracker B MPPT 1: 100% MPPT 2: 100% / Any symmetrical distribution (e.g.: east/west 65% / 65%) / Any asymmetrical distribution (e.g.: shading 80% / 20%) (limit: minimum input voltage) = = = = = ~ P AC/NOM = 5 kw 15

16 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN DYNAMIC PEAK MANAGER / New MPP tracker for maximum yields / 1-2% yield benefit in case of shading in the morning or evening (e.g. chimney) / Up to 4% yield benefit in case of shading in the morning or evening (e.g. dormer window) / Optimum operating point found across the entire input voltage range, even in the event of shading / Quick adaptation to changes in insolation and in the lower power range / Adaptive, dynamic adjustment of the algorithm with environmental parameters taken into account 16

17 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN: DYNAMIC PEAK MANAGER / Example: Typical morning shading scenario 17

18 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN: DYNAMIC PEAK MANAGER / Example: Typical morning shading scenario (chimney) P [kw] 4 3 P DC U DC P DC U DC Without Dynamic Peak Manager With Dynamic Peak Manager 2 1,3 kw 1 Additional yield ~0.5 kwh Daily yield without DPM: 26.0 kwh Daily yield with DPM: 26.5 kwh 0,3 kw 0 Time = + 1.9% yield 18 10:30

19 MAXIMUM FLEXIBILITY IN SYSTEM DESIGN DYNAMIC PEAK MANAGER / Comparison: Standard MPP tracker* vs. Dynamic Peak Manager / 1 hour shading in the morning or evening (e.g. chimney) / Annual additional yield: % / 1 hour shading in the morning and evening (e.g. dormer window) / Annual additional yield: % Energy consumption of the Dynamic Peak Manager: ~ 0.05% of annual yield * Standard MPPT, which does not find the global maximum when shaded 19
