[RE-wrenches] Alternative to CT-104 Crimps

[Jason Szumlanski]

We do a lot of crimping bare copper fro bonding, and the NSI CT-104 copper
C-taps for crimping #6->#6-#12 wire are just insanely priced. How are other
doing irreversible crimps of bare copper?

[RE-wrenches] Morningstar MPPT charge controller

[Solarguy]

Wrenches

The Morningstar Sure Sine inverter and MPPT charge controller sound like a
good match considering the reliability of their products. But when I tried
to use the CCs ability to act as a timer to turn on/off the Sure Sine via
its remote on -off input terminals I found that the two are not compatible.
A call to tech support and I find that I must use a third-party relay to
activate the 1P-1T switch on the Sure Sine. 

I'm sure other Wrenches have come across this combination before for a 12V
lighting system so I'm wondering what specific brand or technology of relay
works reliably in a hot location. I prefer to have a DIN mounted relay but
will consider something else. 

Thanks in advance

Re: [RE-wrenches] Morningstar MPPT charge controller

[bob ellison]

I haven't done it but why can't you use a standard lighting photocell to
turn on the inverter? There really is no current involved so the load
shouldn't be a problem.

I am assuming that you just want to turn on a light? 

 

Just a thought,

Bob Ellison

Re: [RE-wrenches] Morningstar MPPT charge controller

[Larry Crutcher, Starlight Solar Power Systems]

I built a billboard lighting system with the Suresine inverter and LED flood 
lights. It is the only inverter that works in the extreme summer temperatures 
in Yuma, AZ. 

The PV controller is the Blue Sky Energy SB2512iX. It has an amazing 
programable lighting controller built in. You will need to use the IPN-Pro 
remote to set up the program. The Aux. output drives a 30A SPST automotive type 
relay for switching the 12 volt line to the inverter. It has been working well 
for over two years.

Re: [RE-wrenches] Small battery bank vs too large array

[Drake]

Hello Wrenches,

Thanks for your help with this question.

I've had a breakthrough on the design of this system.  I talked with 
Tom at Midnight Solar, and he explained that Concord batteries can be 
charged at C X 5 if necessary, i.e., 5 X AH capacity of the 
bank.  The batteries like a fast charge.  They are a bit spendy, but 
will simplify the overall system design.


From the Manual:
"The charging current during the Bulk stage should be set as high as 
practical; higher current mean faster recharge time.  For repetitive 
deep cycling, chargers should have an output current of at least 0.2C 
(20 Amps for a 100 Ah battery).  If the output current is less than 
this value, the cycle life of the battery may be negatively 
affected.  Due to low impedance design, Sun Xtender batteries can 
tolerate in-rush current levels as high as 5C (500 A for a 100 Ah battery). "


It is imperative to keep the system voltage at the required set 
point.  The CC regulation will prevent the batteries from being 
harmed, as the voltage will rise quickly.

Re: [RE-wrenches] Small battery bank vs too large array

[Larry Crutcher, Starlight Solar Power Systems]

Drake, 

The ability to charge at much higher amperage is typical of all AGM batteries. 
The recombinant technology does not produce much heat before the internal 
resistance rises and the current naturally drops. AGM's require up to 20% less 
energy to recharge as very little is wasted as heat. 

For me, the important aspect of AGM's is that with higher initial current (over 
sizing the PV system or the ability to use a large charger) and higher 
efficiency, you reach the absorb set point earlier in the day. For off grid 
systems, this means you will have more sun hours left to achieve 100% SoC. For 
these reasons I generally recommend AGM's.

Re: [RE-wrenches] Morningstar MPPT charge controller

[Maverick Brown [Maverick Solar]]

We used an Omron G2R-1-S-DC12S available from mouser.com. Don't forget to
get the DIN socket as well. I think that is a P2RF-05-E.
 
Good luck
 
Maverick
