Re: [RE-wrenches] SMA SB and LiFe
Wrenches, Glen I have installed fortress Evaults on both the older and newer SMA SI inverter/chargers, you will need to make some changes to the charger config with the temp sensor. It is somewhat wild in the current state and must be locked down, it is not very difficult to do and makes a big difference on how the charger works. You will need to remove the battery temp sensor and install a rheostat with a fixed resistor to simulate the 25 C reading, the resistor gets you close but the rheostat can be adjusted for your particular climate and system. BTW, this goes for most any Li type battery. Outback is easier as the sensor unplugged defaults to 25 C. Jerry Fun Times!!

Re: [RE-wrenches] SMA SB and LiFe
Hey Glenn, I just started running a LIFEPO4 battery with a Sunny Island, no closed loop communication but with settings pretty much what Fortress has on their Sunny Island sheet. Settings are lower than what some LIFE’s specify, to avoid a voltage jump / high voltage error at the end of the charge cycle from what I’ve seen. Best regards, Lloyd Lloyd Hoffstatter, M.S.

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!

[RE-wrenches] SMA SB and LiFe
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!
