Almost 25 years ago, when we built our off grid home, we looked at the limited
options then available one of which was the Sunfrost. After looking into
things like relative efficiency, initial purchase cost and system requirements,
it became pretty obvious that the Sunfrost was an overpriced
This was 22 years ago and I got my buss bars from a battery distributor who did
large backup installations for telco systems. He was horrified that we in the
business were paralleling series strings together in a daisy chain. Said it
was the best way to give batteries an early death. I had

HI All,
I’m wondering if anyone has a good source for battery buss bar stock.
Either pre made ones or stock I
The battery engineers at the outfit that first taught me how to install
using buss bars cabling individual series strings in parallel to the buss
bars were also adamant that using that configuration would allow for
different size and capacity batteries to be installed in the same bank. I
What size are the banks are are they series/paralleled across the terminals?
That can cause one or more cells to fail, generally starting on the negative
terminal. The set that failed on me was series/parallel across the terminals,
old school, and the cell closest to the main negative
Jesse,
I’d also add a good buss bar connection system for your battery banks, maybe
even do one set of series/parallel connections (old way) across the bank and
one set of connections with the series strings interconnected through buss bars
rather than direct string to string. Much better
The ability to string multiple powerwalls together to get up to 90 KWhrs of
storage makes them modular and likely quite easy to install. The price is
rather high but I haven’t priced batteries lately for comparison. The built in
safety features will make for a good selling point too.
