RCD Nuisance Tripping

32

• Residual Current Device

• Detects leakage current

• Rated @ 30 mA – avoid heart attacks caused from electric shock

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

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 VExport

• 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

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!
