[RE-wrenches] alternatives to Outback GSLC xxxx box?

Tue Mar 1 14:40:21 EST 2022

Hello Jason
yes the GSLC does come with a top. Please see Page 6 in the link below.
https://outbackpower.com/downloads/documents/inverter_chargers/radian_gs_load_center/gslc_plg_web.pdf
on the shunts as asked earlier in this thread
1000 amp 100mv
And
1500 amp 150 mv
Both have the same ration as the 500 amp 50mv normally supplied by OB
I hope this helps.

Hiya William,

Does the empty GSLC come with a top, or do you fabricate a top where the Radian usually bolts on? Would love to see a picture of your dead front hinge,  I always wanted to to that….
Thanks,

Kirk:

We purchase only the empty GSLC cabinets. They do include the breaker brackets and bus bars. I have received the cabinets missing hardware so check the inventory beforehand.

Here are a few hints you probably already know:

The shunts are the shoddiest construction and it is very easy to break the plastic base. Torque the upper shunt bolt after all other bus hardware is torqued.

I recommend using two 175A breakers. For some troubleshooting procedures it is necessary to isolate the two power modules.

An empty GSLC cabinet makes an acceptable PV recombiner. We cut off the bottom dead front tab and substitute a hinge. We wire the breakers with the dead font tilted out flat and all leads hinging at the bottom.

We never install any AC breakers in the GSLC cabinets. The back-wiring is just too awkward. Instead  we use outboard breaker panels or panel boards—one for Gen Fed and one for Inverter Fed.

For bypassing we fabricate custom slide plates bolted to the dead-front to interlock output breakers. It’s not listed but with good craftsmanship it looks official.

Here are a few photos:

I hope the above info is helpful.

All,

I am doing a multiple stacked Radian GS8048 system. And all I need in my design is two OB 175 a breakers in a box which integrates w/ each respective inverter. The manual bypass switch is useless, for all inverters need to be bypassed at once using a single external bypass. OB does not make a version of the GSLC which only has the inverter breakers. They do make an empty GSLC with nothing in it. But no mounting assembly for the breakers, and no add-on kit offering to do this either.
I thought Midnite made something compatible, but don't see it on their web site. Any ideas? Thanks.
