Re: [RE-wrenches] Simpliphi Phi 3.8 48V Case Color

[Roland - RES via RE-wrenches]

The first white cases that came into the market were for the AmpliPhi model which had coms for closed loop.Later on they stopped manufacturing the black polypropylene case on all models, all models now come in the white power coated steel case. Which is a bummer here in Hawaii, we liked the black case for rust issues, we have started to have rust issues on the white cases, I believe it had something to do with 9540a testing for fire propagation. We have done up to 24 (no comms) in parallel, I don't believe SimpliPhi gives a max.Roland ShackelfordPresident / OwnerNABCEP PVIP #091209-162Office 808.775.7410Mobile 808.938.9239Power Solutions for Generations Renewable Energy Services, Inc."

Hi, We are doing our first system with these two

product for RS is the TS4F.  Tigo has me a little bit walking in
circles. 
  
I told them that SolArk says not to use the 12VDC RS output
  terminals for connecting the transmitter.  I gave them the
  attached drawing which they ask for, which shows the transmitter
  connected to a 120VAC/12VDC breaker which they supply.  They told
  me to wire the 120VAC source to the main service panel so the
  array would shut down on loss of power. I told them that is
  exactly NOTwhat I wanted to happen as that would stop the battery
  charging when there is a loss of utility power. I said I wanted
  the 120VAC source to be the back up loads panel. After about a
  week of calls and emails, I got an email back saying to use the
  SolArk 12VDC terminals for RS.  I just emailed them a screen shot
  of the SolArk manual that says not to do that.
At this point, I am asking anyone on the list to let me know how
  they wired the transmitter successfully. Thank you for any
  guidance, Chris Warfel

Re: [RE-wrenches] Outback_Inverter firmware mismatch

[Roland - RES]

Aloha Wayne,

We too have been plagued by this issue, that has been extremely frustrating for 
us and our clients. 

The newest 1.4.6 firmware is supposed to fix this issue. We have updated our 
systems with this and so far so good. However because of the sometimes long 
delays between the faults we can't be certain. 

Prior to this most common fix was replacing the mate. 

Also on FP2 we had a couple factory units have the hub jumpers set for the 
wrong stacking. I believe they were set for parallel operations versus series. 
Strange it would work fine with the jumpers either way for a long time. But 
it's worth a check.

Re: [RE-wrenches] Sol ark 120v issues

[Roland - RES]

We have been successful with double and triple Sol-Arks being able to start 
just about any single phase loads, the imbalance tolerance is multiplied per 
inverter. 

Like others we had numerous single inverter sites having issues offgrid, 
primarily while completing construction, chop saws and air compressors being 
the main culprits. We measured a max surge amp as high as 60a for a 1hp 
compressor and large chop saw. 

We have been successful in using an Outback X240 balancing transformer to 
resolve the bus unbalance shut downs. 

Does anyone know of a non outback balancing transformer available on the market?

Re: [RE-wrenches] Slave Radian not showing up on Hub10 or @ Mate3s

[Roland - RES]

Hey Chris,

Sounds like a failed power supply board Outback part SPARE-215. If the unit is 
under warranty you should be able to get a replacement through OB tech support.

Re: [RE-wrenches] Radian Question

[Roland - RES]

You can select which power module is used with the Mate under the inverter 
settings. Left, right or auto. This way you won’t have to physically swap the 
modules to determine if one has failed.

Re: [RE-wrenches] Grid tie w/o battery no sell back

[Roland - RES]

Enphase, Solar-Edge, Pika, and I believe now SMA. You can check HECO advanced

Re: [RE-wrenches] FXR , Mate 3, AGS and Must Run

[Roland - RES]

Oh,

The replacement Mate 3 with the older firmware, didn't have the power line 
emblem on the main screen. Although it was the one that put the CC into GT 
mode. I didn't leave this plugged in, I was just confirming the mate worked 
before taking it out to a job.

Re: [RE-wrenches] Sonnen Battery & Outback Radian Inverter

[Roland - RES]

FYI that's a showroom unit with none of their internal wiring, and dummy 
inverter and batteries to keep it light. An actual unit has a tremendous amount 
of factory wiring between contractors, 200a auto transfer switch CT's and 
sensors along with a powder coated steel door in place of plexiglass. The 
Batteries are manufactured by Sony, they come in 48V 2kWh blocks that get 
paralleled together.
