[RE-wrenches] Stainless NEMA4x load center, SolarDeck w/ breakers

Wed Apr 23 10:50:45 PDT 2014

Here is exactly what I ordered:

(1) RST0760-41AD Soladeck AC/DC Combiner Box
(1) RST0784AC-3K Soladeck AC 3 Circuit Busbar Kit
(2) RST1455.20 ABB Mini Circuit Breaker 120/240VAC 20A
(1) RST1455.15 ABB Mini Circuit Breaker 120/240VAC 15A
(1) RST1440.080 Soladeck Power Block 600V 80A

This model has a cover that is bumped out to fit breakers. Here is a pic
of the closed up box.

Again, I'm not really happy with the way I brought the Enphase cables into
this Soladeck. The knockout center-points provided by the manufacturer are
too close together to accommodate five water-tight glands, so I used some
offsets to make more space. If it wasn't my own house, I would have wanted
it to look much prettier for a customer.

One thing I highly recommend is along the top and sides to use sealant as
indicated in the manual, then sprinkle a generous amount of granules in the
sealant. Otherwise the cover and your fingers get gummed up when taking the
cover off.

The manufacturer's website and documentation is woefully inadequate for
this product. They need to clarify it, obviously, based on this discussion
if they want to sell more. It's a great solution IMO.
