Re: [RE-wrenches] Xantrex 30 kW inverter

Marco OK, Sunpower can be an issue with the positive ground issues, I will look at which inverters we used to work with the SP 225 some time back Jerry On Thu, Aug 9, 2018 at 3:15 PM, Marco Mangelsdorf wrote: > Hi all, > > > > I’m in need of a vintage Xantrex 30 kW (PV 30208) inverter. > > > >

Re: [RE-wrenches] Xantrex 30 kW inverter

Hi Marco, SMA may have a solutions for this called the PV offset box. I think it would allow the negative ground without the degradation. http://files.sma.de/dl/15437/PVOFFSETBOX-DEN1444-V10web.pdf I have never used this but thought it was an interesting product. On Sat, Aug 11, 2018 at 2:29

[RE-wrenches] Xantrex 30 kW inverter

Hi Jerry, I'm talking about the need to ground one of the current carrying conductors back to earth, not the metal equipment frame. The SunPower pre-Maxeon cells required that the positive conductor be grounded. Which is not possible with TL inverters. There's no safety issue to let these older

Re: [RE-wrenches] Xantrex 30 kW inverter

Marco Am I missing something, all arrays are grounded even in Hawaii, I have systems using the SMA Tripowers and ABB Trios, they are required to be grounded and tested as so. Now if the modules "Leak" this can cause resistance leaks in the array, its like a GFI. I have had issues with inverters in

[RE-wrenches] Xantrex 30 kW inverter

Hi all, I'm in need of a vintage Xantrex 30 kW (PV 30208) inverter. Anyone happen to have one or know of someone who might? Can't use a TL because the array needs to be grounded. Mahalo, marco --- This email has been checked for viruses by Avast antivirus software.
