Hi Mark,
We have lots of Enphase installed on all sorts of home. The most sure fire
way of getting communication
is coming from solar, as the tank has
the thermostat from the grid side as well.
It's a solution still looking for a problem.

System marketing emails? Any first impressions? Here are my initial
thoughts:
Pros - provides hot water in utility outages, no interconnection
hassles
.
Come to think of it... that really applies more to 240Vac service. 3-pole
breakers and panels are more pricey.

Be sure to read Enphase’s tech sheet on center tap of branch circuits
on the outside of a building on the north side. That one works
fine. I observed the fault in the morning during 80 degree ambient temps.
And pointers would be appreciated. All the manual says is Contact Satcon

Any first impressions on this new product?
WEEBs require replacement after modules are removed for service. I wonder
of the IronRidge mid-clamps biting into the same module frame locations
after service have been tested and approved. Moving the module to bite into

Let me start be saying that I'm talking about mechanically attached
tilt-mount solutions capable of handling 172 mph design wind speed, ASCE
7-10. Ballasted systems need not apply.
We've used a variety of hardware for TPO membrane flat roofs, which is
becoming more and more popular around here.
, they may not be cut out for battery backup living.

Friends:
I wrote a draft white paper to discuss the issues relevant to PV Assist
systems. If you are up for along
relative to the battery and the PV production is
variable (think air conditioning).
I'll watch this discussion with interest...

Friends:
We have been receiving a flurry of requests
Are they missing the fact that the inverters used for battery backup RE
applications are also high output sophisticated battery chargers and
transfer switches all built into one integrated unit intended to work
together with available monitoring and coordination with charge controllers?
I
interested if anyone has any low power consumption ideas.
