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!
