Re: [RE-wrenches] Radian AC inputs

2019-08-08 Thread Ray 
To add to this point,  a customer inadvertently wired a 100 amp 240 vac 
Tesla charger circuit into an Outback backup system.  We later had to 
rebuild the inverters because they had cooked the 60 amp rated transfer 
relays.  The 50 amp breakers had tripped occasionally, but apparently 
not enough to save the relays.  The relays were not completely gone, but 
were no longer reliable.

Re: [RE-wrenches] Radian AC inputs

Hi William
Sorry for the delay in getting back to you.
Good catch on the observations in the Radian Quick Start Guide.

Link to Quick Start Guide
http://www.outbackpower.com/downloads/documents/inverter_chargers/radian_8048a_4048a/gs_8048a_4048a_quick_start.pdf
Link to the Radian Installation manual
http://www.outbackpower.com/downloads/documents/inverter_chargers/radian_8048a_4048a/gs_8048a_4048a_install.pdf


The QST statement

Only one AC source can be wired at a time;  use an external selector switch if 
more than one source is available.”

Is incorrect.
All Radian Inverters have 2 ac inputs, an external selector switch is 
unnecessary. That almost has to come from the FX inverters.
I have notified the Technical Manual Writer and he will change that .
Thank you

On the other observations I will have to split hairs.
The easiest first.
In the Quick start Guide
We do recommend #6 AWG THHN copper wire
under the heading
AC Wire Sizes and Torque Values


In the Quick Start Guide
Under
AC Wiring Notes
It is stated:
The Transfer Relay is rated 60 Aac….
Then recommends   up to a maximum 60 amp breaker.
This is not a false statement.

In the Radian Installation Manual
On Page 38 it is stated:
All overcurrent  devices in Permanent Installations must be sized for 50 Aac or 
less.

So perhaps a little history
The relay is the same ac input relay that was used on the Trace SW inverter, 
and on the Xantrex  SW and SW + Inverters.
It is rated at 60 amp pass through. In the GS installation manual we state a 50 
Amp breaker because that is what we use in the GS load centers.
Throughout OutBack’s history the ac breaker size has changed between 50 and 60 
amps.
The relay itself has not changed.
I happen to like the 50 amp breaker as it should trip before the relays get 
stressed.

I hope this helps.
Take Care All

Friends:

I was wiling away the time perusing a Radian (GS4048/GS8048) quick-start guide 
that came with a recently acquired set of Radians.  I was quite surprised to 
see the AC inputs, outputs and throughputs are shown in the quick-start guide 
as rated at 60 Amp AC. The guide also indicates a minimum wire size of #6AWG 
(does not specify CU or AL, will assume CU).

I always remembered that rating to be 50 Amps AC.  I checked old and new 
installation manuals and they all say 50 Amps AC.  Am I missing something?

The guide also says:  “Only one AC source can be wired at a time;  use an 
external selector switch if more than one source is available.”  It really 
sounds like this section was cut and pasted from an FX/FXR manual by mistake.  
Anyone catch this?  Lones, you out there?

William

[RE-wrenches] Enphase M-250 Source

2019-08-08 Thread Jason Szumlanski 
Does anyone have a source for discontinued M-series microinverters? I'm
starting to get a steady stream of clients that want to add to their
systems.

Adding a small quantity of IQ microinverters is not cost effective due to
the cost of the Envoy. We designed many M-series systems to accommodate
add-ons to non-fully populated branch circuits to allow for cost effective
add-ons. We're having a hard time fulfilling that promise due to lack of
M250s out there.
