I have posted this question on another forum.
Hello calling any experts.
I have three systems to install and am trying to work out RCD requirements, not used Aurora inverters before and can't find any information in the installation instructions.
System 1
Farm with 100A TNCS supply I have already wired some buildings which are fed by sub main and are TT <100 ohms with 100mA S type main switch and 30mA for sockets. System will be connected to submain with XLPE/SWA. Does the Aurora PV1 3600 inverter require a type A or B RCD, array frame will be main bonded 6mm cable to TT MET.
System 2
House with 100A TNCS supply and Earth rod/buried 25mm copper cable connected to MET <200 ohms, array frame main bonded 10mm cable to MET. AC cable In Nexans Allsecure NXS (cable with full earth screen) Does the Aurora PVI 3000 inverter require a type A or B RCD.
System 2
House with 100A TNCS supply and earth rod/buried 25mm copper cable connected to MET <100 ohms. Array mounted on steel frame steel profile roof detached garage with main equipotential bonding exported in 10mm 3core XLPE/SWA to garage. Inverter SB4000TL I have designed this with a 100mA type A RCD as per SMA instructions.
Any comments greatfully received
