Pharmaceutical company? Ethics? Opps.
I thought Schneider buying them would help, but they have no idea what
they're even selling these days. Have you seen their website? I can't
even find a spec sheet for the TR in all that "Solutions for PV systems"
mumbo jumbo.
The TR is a classic example of what I call 3C. Cheap Chinese Crap. If Xantrex
had any ethics at all they would have killed that line and refunded everyone's
dough years ago.

As I prefer sine waveform, I haven't built a system with a DR in
ten years and have never used a TR. However, we just installed a

Ray,
I've got a customer that has the same problem with a dual TR inverter
system. When we first complained, Xantrex promised they were working on
a fix. That never materialized and now the TR is out of production. It's
a lousy product and customer service has been the same. A few months

Hi Folks:
I just finished up another ugly rewire project for a customer that had
another"installer" put in a Xantrex TR inverter.
We fixed numerous wiring issues, including neutral bonded to ground in 7
different places!
The issue we're having now though, is that the TR inverter output

If you run them thru the formula...
Time=.42 * C20/I...
Time = .42 * 3280AH/170amp (Max Current)
That's 8.1 Hours Absorb... But you DON'T want the inverters hitting a premature
absorb because that will throw the FNDC SOC meter/timers off.
Also I didn't mention that they were only using a 5000
Steve.15 hours of Absorb charge!? Is this just during the initial
charge during commissioning? to set the Flexnet DC calibration?
Thanks for the clarification...

Wayne,
Sorry about the delay!... I've been in wonderful sunny Nigeria dodging
kidnappers and car bombs...
All Rolls batteries require a bit hotter voltage when charging and especially
when you are using multiple parallel strings.
With that system I would suggest if you are using the Outback T
Hi Larry,
A PV module is not exactly a constant current source. It has a power curve. At
0 volts in any given insolation, it's current will be the highest. As the
voltage rises, the current drops, until the current is 0.
If you put two strings in parallel that have different voltages, they will b
