The origins of SunSpec certainly started with grid tie, as that's where the
volume has been. However, they've welcomed participation in creating a charge
controller standard with open arms, and they are actively developing an
inverter control standard. OutBack just received certification at the

Following up William's comment, here's an eGauge with battery voltage
monitoring: http://egauge2093.egaug.es/
De-select all the register choices at the bottom of the graph except for
"Battery Voltage". The y-scale is in Watts but it's really V-DC; the folks
at eGauge are working on that.
According to a 2008 Xantrex price list, MSRP was $3,025.

Hi Folks,
Im looking at buying a brand new SWPLUS 4024 inverter from one of my
clients for power for a home project. Does anyone have any idea how much
these sold for when they were available? I want to give her a fair deal for
this nice piece of gear. Thanks!

After looking at their Member section, it seems unlikely that they are pursuing
the off grid portion of the industry. I see that Outback Power is a member but
the rest are related to grid tie.

Hi William,
Here is something else for you to stew about.
The premise is that only China subsidizes its solar and we don't.
In fact we do by our tax breaks for systems. So we don't at the point of
manufacture, but we do for installs.
In my view this is a direct subsidy, we just do it a differen

I have heard there may be an open-source solar (perhaps RE in general) data
transfer protocol coming, that will allow for different manufacturers
equipment to talk. This could allow for many possibilities, including

that. Thanks for the info!

I second Larry's recommendation of Blue Sky charge controllers.
I've used them for several years under some very adverse conditions,
yet they've performed flawlessly. Support too has been excellent.

I haven't seen much discussion about the tariffs, but I think the current
plan is really an outrage. I've toured the SolarWorld factory twice and
used many of their modules---I'd like to see US Solar manufacturers
succeed, but I've also toured Chinese factories, and I'm thoroughly
