I've been making gutter bus wireways that run the length of batteries and
inverters allowing for exact lengths of cables. I think I posted a picture
of an exceptionally large one. 24' long. I'm looking at the rack mounted
set up because the bussing and cabling is done. 3 racks of 6 5kwhr
Sounds like a good design. As a tangent question to 13 parallel batteries, such as you’ll need Michael. How are people wiring larger numbers of lithium batteries together in parallel?Massive buss bars which I’m not sure how to do in a code compliance way. Or Not worrying about different cable
Jay,
I'd like to design for 60kw supply and 100kWh battery. I think I'm going to
try the Discover rack mount set up rather than AES's and custom bussing.
Jason,
That's exactly what I was thinking, if I go the Sol-Ark route. Last time I
ordered custom panelboards like that, they were six months
Wrenches,
I have a dusty stack of SolarPro magazines and am curious if there are
folks on the list who might want them. At a glance I see issues from 2014
and 2017 and presumably they're all from around that time. There are also
some copies of Home Power in there. Please contact me off list if
If 40kw is the peak and then there are new added loads, what 50-60kw? If it was me I’d be designing the inverters to handle the 50/60 kw with future expansion capabilities beyond that. Then how much kWh of storage are you going to need or maybe are planning for?At some point maybe looking at a
I like the Sol-Ark idea having had a few dual-unit successes recently. In
terms of combining them, the Sol-ark manual has a good triple unit wiring
diagram on page 53. You would have to use two 400A panelboards with three
200A breakers for each to follow this diagram. However, I don't see the

Great questions. We have had great success with the Sol-Arks, starting with
the 8’s. Have completed several with twin 15’s and the systems have been great.
There was a software/ firmware issues when they first came out.
Having spent years installing AC coupled systems (
I've been asked to build a back up system for a grid connected estate. We
haven't done many of these and I thought it best to ask those who have some
questions before I go about reinventing the wheel.
Here's the existing infrastructure.
