44 Solis Inverters Aquaculture Park 99W 99MW SePiaoTu Photovoltaic Power Generation Project in China. The SePiaoTu photovoltaic power generation project covers 4200 acres, with installed capacity of 99 megawatts, the total project investment exceeded 700 million Yuan. The project has required construction of 52 new supply towers and a new double supply line km in total. The tower foundations started September 2016, early 2017 saw the main electrical construction, and March 2017 saw the on-site sub-station beginning finalised. The park has two 50,000 kva main transformers, single bus wiring, 110 kv outlet with 1 supply back. Annual power generation is expected to reach about 110m kwh.

53 Inverter Topology

54 Advantages Safety protection function Boost circuit Inverter circuit Redundant control ISO, GFCI, AFCI, PV over voltage, PV reverse protection Low voltage start up (Get more power one day) Fast MPP response Great EMC performance High efficiency, low temperature rise

55 Static MPP Efficiency Accurate current sampling in low output power condition and cross the full voltage range

56 Dynamical MPP Efficiency Problem: Efficiency lost when MPP curve change Solution: New calculation algorithm to achieve much shorter response time.

57 Conversion Efficiency

58 HALT and HASS HALT: Find the weakness of EUT in short time, optimize design. HASS Screen the mass production. Find the defect of product caused by design, manufacturing or material.

59 HALT and HASS Equipments Temperature and humidity chamber Vibration platform

60 HALT Methods Cold step stress Hot step stress Temperature decrease from -20 by step of 10, each step lasts for 1 hour. Temperature increase from 60 by step of 10, each step lasts for 1 hour.

61 HALT Methods Thermal shock test Vibration step stress Accelerated speed increase from 5G by step of 5G, each stage last for 1 hour. Thermal shock and vibration combined test Temperature cycling from -40 to 110, each temperature stage last for 1 hour.

62 HALT Result Cold step stress: Temperature reduce to -40, EUT works normally. Hot step stress1: Temperature increase to 50, EUT output power reduce to 40% Temperature increase to 60, EUT output power reduce to 0. Temperature increase to 120, EUT work normally. Hot step stress2: Remove thermal sensor, EUT work with full load, until temperature to 100 EUT shutdown Analyze: Boost diode (IXYS DSEI30) is broken. Because its temperature range is 150 Solution: Change to higher range diode(apt30dq60b) which temperature range is 175 Verification: Repeat Hot step stress2, EUT failed when the temperature rise to 120 Vibration stress: Accelerated speed increase from 5G to 40G, EUT works normally. Thermal shock: From thermal shock -40 to 110, 5 cycles, EUT works normally.
