[RE-wrenches] SMA SB and LiFe

[Glenn Burt]

Hello all - best wishes for the new year.

 

I have a client with an aging (dead) AGM (16x Concorde PVX-3050T) battery
bank with two Sunny Island 5048 inverters (and a few SB in the mix too) in a
GTWB configuration.

Has anyone successfully replaced an AGM battery bank with a LiFe ESS
solution with closed loop comms and Sunny Islands?

Something like a Fortress eVault max?

 

Or should I simply replace the existing AGM's with the same model batteries
and let it go another 10 years?

 

Thanks for the feedback!

Glenn
