- 13. High Power Generating Capability 13 • High efficiency across all products > 97 % • High input DC voltage • PV Array oversizing – 30 % • Reactive Power Control up to 0.85 lagging / leading • Wide MPPT voltage range • Multiple MPPT´s • East / West design • Flexible string lengths MPPT A MPPT B Flexibility
- 14. Did You Know 14 • IP 65 rated enclosure and RJ45 comm ports • Tolerant to temperature [-25oC – 60oC] • Heatsink • Cooling Fan • 3 kW - up to 10 kg lighter – lowest DC start up voltage – lowest DC shutdown voltage • 5 kW – up to 7 kg lighter – lowest DC start up voltage – lowest DC shutdown voltage • 15 kW – 9 kg heavier – not the lightest • Quality internal components
- 15. Sunclix DC Connector 15 • No special crimping tool required • 2.5mm2 – 6mm2 • 40 A CCC – 1100 V • Terminate cable up to 10 times

- 17. High Reliability 17 • Comprehensive Testing • Zeversolar (internal) • SMA – 30 years of experience • Tests include:- • Manual Parametric Test • Fan control test • Residual current test • ISO test …… • ATE Test • Environmental Verification Test • IPXX test • High&low temperature characteristic evaluation • High temperature & humidity test, Drop test …… • Field application test • Teamwork • Zeversolar and SMA engineers work together `Testing in accordance with SMA standards´
- 18. „All in all, the product, Eversol TL3000, is operating smoothly and steadily. We have expectations that customers will be satisfied with it.” --- SMA Test Centre Feb. 2014 18 Summary PASSED
- 20. Overview 20 Data collector PMU（Power Management Unit）： • Comprehensive data and event collection. • Upload data to cloud storage, local/remote monitoring via network connection. • Support power regulation required by BDEW and EEG PMU Solar CloudZeversolar inverters RS485 Internet Monitor interface Solar Cloud： URL: http://solarcloud.zeversolar.com/

- 32. RCD Nuisance Tripping 32 • Residual Current Device • Detects leakage current • Rated @ 30 mA – avoid heart attacks caused from electric shock X X X X X X X X X X XX Addition of PV causes Upstream RCD´s to trip Some inverters disconnect after 5s on loss of mains Back Connect to supply side of main RCD • Zeversolar inverters have an internal Residual Current Monitoring Unit • We recommend a 120 mA RCD Type A or B
- 33. High Line Voltage 33 • Typical in rural properties • Measured line voltages exceeding 250 V • High irradiance + low load = export power -> voltage rise – inverter trip 255 V Export • Turn on more load – boil some water in kettle or turn on stove • Ask DNO to change the taps on Tx to reduce the voltage
- 34. Oversizing PV Array 34 • Oversize by how much? • 10 % in areas of high irradiance • 20 – 30 % in areas of low irradiance • 3 kW Array Vs 4 kW Array – SB3000TL – 250 W Trina Solar Panels – London • 3 kW – 2732 kWh/yr Vs 4 kW – 3647 kWh/yr • Pvsyst 5.54!
