I recall seeing somewhere that had verification procedures for verification of your testing instruments, but I can't remember where that was.... I'm wanting to make up a verification rig for periodic verification of my instruments.

Great stuff, thanks again AlecK

Thanks for that AlecK. How about a RCBO for the mains, and another for the inverter? - come off the load side of the mains rcbo before the selector. Label both RCBO's as "Main Switch"?

Bus converted to a motorhome, 230v side of things - I am fitting a selector switch so the user can select between "inverter-off-mains" for supply to the 230v installation. Part of the installation is a 230-12v charger for charging the house battery. I am wanting to inhibit the charger from running f...

Who are you meaning as ES?

Thanks again

So I emailed this off to the supplier last night: Hey David, The system voltage is determined according to AS/NZS 5033:2014 A1+A2 by the clauses 1.4.51 and 4.2, image.png So 143.4+(-0.29/100(3-25)(3) PV array maximum voltage = 143.59V Well above 120v to be included in ELV and is therefore LV and req...

Further to this, I recall reading somewhere in the 5033 standard that the max input voltage of the pce cannot be exceeded - the max voltage of the solar inverter is 145v, with the temp. compensation this is over. - I'm having trouble locating the clause for that, any idea where I can find it?

Hey guy's and gal's, A client had purchased an off grid package - 5kW MPPT Solar inverter - (Charge controller, Mains charger, Inverter all in one), 300Ah Lead Acid storage - 48v, 9 ODA380-36-M 380w solar panels - 3 per string. What determines the system voltage - My interpretation is the Voc of the...
