William,
I think Right Hand Engineering
<https://www.righthandeng.com/rhe_swma_memory_adapter_manual.pdf> still
makes the device that will keep the SW memory alive. Batteries need to
be changed every few years.

Friends:
This is a follow up on the question I asked about anyone having actual
experience integrating Simpliphi batteries with a Trace SW inverter
system.
I read the battery and integration manuals carefully and spoke with
Simpliphi tech support. The systems are absolutely compatible but
only if the inverter and charge controllers are programmed correctly.
Therein is the problem: If the SW inverters lose DC power, the
programming is erased and the inverters reset to factory defaults.
These default settings are not acceptable for safe operation of the
Simpliphi batteries.
If the client is capable of determining when the settings have been
reset and can reprogram the inverters when needed, then maybe the
design is acceptable. In the case I am working on, the client does
not have these capabilities. It was decided to replace the dead
batteries with the same AGM style batteries currently in use, not the
Simpliphi.
Thanks for your input.
