Jay:
Excellent question. This is an issue we have wrestled with on every Radian job. Here's the situation: 1. The empty GSLC cabinets are supposed to come standard with all the parts you described. 2. The cabinets are all too often shipped without some of these parts. 3. There should be a total of six bus bar parts and some hardware. 4. There are four parts for the positive circuit and two for the negative. 5. Three of the positive bus bars are to connect the inverter positives to the breakers. The other one is a flat plat with six or more holes to connect the battery side of the breakers together. 6. The two negative bus bars are shipped attached at one end to the negative shunt and unsupported on the other. The weight of this assembly is such that if the cabinet is dropped even the slightest in shipping, the moment arm of the assembly will crack the plastic base of the shunt. Outback shunts used to have a solid Bakelite base. Now they are hollow plastic. (Order one or two extra shunts for your FNDC circuits. They do not come with the FNDC.) 7. You need to verify you received the four bolts to thread into the inverter DC plus and minus terminals. 8. You need at least one metric nut and lock washer to assemble the positive bus bars. 9. When you receive your GSLC cabinets, you should open them up and verify you have all the parts. I recommend you pull the shunt and inspect the back of it for cracks. 10. Install the upper positive bus bars while the shunt and negative bus bars are out of the cabinet. This will allow more room for fingers and wrenches. 11. I have attached a photograph of the parts you should find with each GSLC. 12. The stainless covers are often covered in greasy fingerprints that are hard to clean. You may want to bring stainless cleaner. I have complained about these problems to Outback many times. I have not ordered a GSLC for about 6 months, so I don’t know the current likelihood for problems. I’d be curious about your experience. I cultivated some contacts at the factory so I have someone to call to get missing parts sent. By the way, my supplier has been promised lead times of 1-2 weeks for orders. Actual times are double. Plan accordingly. I applaud the decision to avoid pre-wired GSLC cabinets. The prewired cabinets are a total mess. I cannot recommend installing any breakers in the removable dead-front. We have relocated all of these breakers to PV recombiners and AC load centers. We fabricate our own interlocks. Contact me off-list if you have more questions. I hope the above level of detail helps. I’ve been in the field with no cell coverage, a deadline, tight budget and then opened the boxes to find parts missing. I wish to help my colleagues avoid that headache. Good luck.

( its the part that goes from the breakers to the power modules) And if so where? My next GSLC I’m looking to use the most striped down version but if I can’t get the bus bars its hard to mount the main inverter breakers. thanks jay Peltz power _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
