Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

2015-11-06 Thread b...@midnitesolar.com 


I might take a clamp on ammeter and check the Classic's battery side 
current.

Then maybe turn ON the generator and see what happens to the current
on that line.

it is possible that the generator is charging during those morning

the customer just went on vacation and the breaker tripped while he 
was gone.


On my first return visit I re routed the controller battery + from the 
battery + buss bar to the battery + on the battery bank itself as this 
had solved an similar issue in the past.


So for tomorrow's visit I am planning on taking a new breaker and a 
new controller.  Is there anything else that I should replace?

It is technically possible though for things to not work exactly
correctly.  I am not saying that this is
for sure happening, but it is possible.   The ramping up in
battery voltage from the chargers should
be plenty slow enough for this not to be a problem but I am wildly
speculating that this could happen
and cannot rule it out.  There may of course be something else
completely different happening here
though.

If CBI breakers are being used, these are known to be extremely
fast at tripping when overloaded.

Also, what, if any SPDs are connected to the system ?

Even so, how will any current from any other source pass through
the breaker unless the Classic is presenting a load? I suppose
something else could be wired through the breaker but I’m
guessing Daniel would have looked at that.

Re: [RE-wrenches] Solar edge

2015-11-06 Thread Andrew Truitt 
They might be referring to the alleged upcoming release of a SolarEdge / Tesla 
Powerwall integration that is currently in the works. I think it's supposed to 
leverage the similar SE output and Powerwall input voltages.

Hi Jay,
I don't know when you will be able to buy it, but yes, they are moving into the 
solar + storage scene, as one of two inverters set up to work with the tesla 
powerwall. The other being Fronius.

Hi all

Solar edge doesn't make any optimizers for 
battery based systems, right? Just their standard string grid tie ones. 
I've got a client who's telling me they do. 
Just checking

[RE-wrenches] watt sun passive tracker

2015-11-06 Thread Jerry Shafer 
To all the Wrenches out there
I am looking for a primary gear drive (driven gear failed) on a Wattsun
array technologies dual axis tracker its about 15 years old and we are
attempting to repair this one more time, if there is any parts out there
I'm sure someone here would know, The pinion gear and bearing case came
back broken and that's inside the housing. Thanks in advance
Jerry
