With outback fire raptor has been successful, it has a power supply and if
you shut the inverter or use the button either will shut off the RSD. This
is all it is no optimizer, no data, no bypass for shade just RSD.

Have you talked to inter island or R$R, never had an issue getting any off
grid parts from 12 to 48 vdc.

it does depend on your customer, if you never want to have to go out in the
rain and fix cracked tiles under the array, Tile will fail under an array
dry out and crack, freeze and crack, they all crack, I always quote to
strip the roof, comp it and install your array, it will look better c

Personnelly l would replace the stack, rather than them loosing a charge
there might just not be any charge to begin with. Once the batteries settle
they just are dead. You can isolate and load test if that makes the
customer feel better.

Jay, wrenches
Does not sound like fortress or blue planet, are these 12's or 24 volt
packs, no interconnecting BMS so resistance is not in check, voltage and
SOC neither. If you interlace the packs AKA 1,3,5,7,6,4 rather then 1,2,3
can you reduce or even balance the cables.

Mate 3S verify that the firmware is 1.4.6
under global charge are all switches "disabled"
in the GS AC Input "Grid",
Charger "Off",
"Grid Tie" set
Offset enable "Yes"
sell is up to you and battery manufacture

I bet if you thought a little harder, you could get it even more
complicated. If the hydro has both freq and voltage control then look at a
dumb charger. Keeping it all independent will be safest. On the other hand
l used an outback and connected a wind turbine to the AC in and the

Can you slit the array in half more or less as a process of elimination,
I've used fire raptor and we had a glitch unit and it was pretty easy once
we split up the array.
