Jay,
I have had good luck with Fortress eVaults with Radians.  3 eVault
18.4’s would do the trick. My only off grid customer running generator free
in Vermont winters has 3 vaults and a Radian.

What specific UL listing(s) are they requiring? Around these parts it's
been UL 9540 for all AHJs, and some requiring that even for lead-acid,
despite the IFC exceptions and so few listed products (the IRC now seems to
require UL 9540 even if the system is not grid-interconnected). UL 9540A is
not an actual listing but an active fire test, results of which can be used
to gain their UL 9540 and/or allow smaller offsets between each ESS unit
and from windows, doors etc if their individual UL 9540A testing results
allow that.

I would think most Lithiums should work. We've used Simpliphi with Radian
successfully.

[RE-wrenches] UL batteries for open loop

2024-05-20 Thread jay via RE-wrenches 
HI All

I got a call from a fellow installer who needs a UL listed lithium battery.  
Say 30-50 kwh.  open loop as its working with existing OB radians.
Could be outside or inside

It so confusing to find the right battery I’d thought I would ask what folks 
are using/recommending.

thanks
