Hello wrenches,
I am wrapping up a job that we adopted mid-installation, that has a couple
grounding options. I am looking for the best way to do it. It is 18 x
Solyndra SL-150-182 with 18x Tigos and an SMA 3000-HF. I am unfamiliar
with the Tigo's and the Solyndra. As I understand it, Tigo's
Dear people:
Does anyone have a line on a really large dual axis tracker--something that
would hold 25 or 30 modules in the ~250W range? I've seen some really big
commercial units, but I have a client wanting a dual axis tracker that'll
hold 25 of the Helios 255s.
THANKS!
Chris Daum
The All Earth Trackers will hold about 5 kW of modules:

Wrenches,
Eden, our main off grid field tech, came across a situation about
which I want to ask the group for advice, please.
The system: existing old/funky off grid 12V residential system, done
by others over many years; this was our first visit. Owner out of
Wrenches,
A local installer called yesterday to ask if we had any XW charge
controllers in stock, to replace on recently killed by lightning. We
didn't. He told me that he had called several distributors and all
are backordered until an order arrives from China.
Hi ,
Deger 5000HD and Sentinel Solar make large trackers.

Hi Allen,
The absorption time is actually only 1 hour for the C-series controllers.
Battery manufacturers are always the final authority on
how their batteries should be charged. If they say you can charge at
14.2-14.4V indefinitely, then increase the float setting.

Hi Wrenches,
I have a high end client who forwarded me this Onyx walkable PV floor link
and wants it on his roof deck:

I know it's a long shot, but do you any of you have any experience with
this product? Any comments also welcome.
Allan,
Do you know what the daily Ah consumption is, or alternatively what the daily
DOD is on the batteries?
830W of PV on a PWM controller should have a peak amperage of about 48A (830W รท
17Vmp = 48.82A). This is only about a C/18 charge rate, which is fairly low but
should be workable as
Brian,
Re:

what the daily DOD is on the batteries?: We don't have
that data. The home has an E-Meter, but the programming settings
were far enough off that I wouldn't trust the historic
