==== Overview ====
This section has been updated to alter its context from research to implementation.  A majority of the data for "other" VFD units has been removed.


Cost is a major driver in the VFD selection process.  As noted, up to $900 will be reimbursed by DTE.  Longevity is an issue, too, as failure becomes a MAJOR issue for pool operation.
Yaskawa GA50U2042ABA:


The consensus amongst "experts" (i.e. individuals with opinions in forums) is that:
* ABB or Allen Bradley drives are top-of-the-line, but come at a cost.  ABB drives are very easy to program (but expensive!).
* Automation Direct drives are inexpensive - but support is lacking.  Later-generation drives (such as the GS23, made by Delta) seem to receive positive feedback.  Earlier generations (GS1, GS2) are to be avoided.  Much of the negative feedback seems to be 10+ years old.
* Delta is usually regarded as "decent" (again, Automation Direct GS23 line).
* Teco may be a step up from Automation Direct and Delta?
* Vacon is well-regarded.
* Yaskawa is recommended both in online forums, and by engineers at a local industrial controls firm.
==== Yaskawa GA50U2042ABA ====
The present front-runner.
* Priced at $842 via local distribution.
* The 2042 model sized for "normal duty" (ND) 15 HP which is appropriate for variable torque (VT) applications (i.e. centrifugal pumps).
* The 2042 model sized for "normal duty" (ND) 15 HP which is appropriate for variable torque (VT) applications (i.e. centrifugal pumps).
* Internal PCBs are conformally coated (IEC 60721-3-3, Class 3C2 for chemical gasses).  <b>This is a huge plus!</b>

* Substantially larger: 12.60" L x 7.48" W x 7.48" D (versus 8.15" L x 4.29" W x 6.06" D for the GS3).
==== Prior Considerations ====
* Support for 1-phase operation (not needed for this application).
* Slightly reduced CT/VT ratings: 47A/49A vs. 49A/51A for the GS23.
* Slightly worse low temperature rating: -10 &deg;C vs. -20 &deg;C for the GS23 (not an issue).
* No FOC or torque control mode?
* No USB port?
* Slightly more/better analog/digital I/O options vs. the GS23 (not needed for this application).
* Might not be compatible with permanent magnet AC motors?


==== ABB ACS310-03U-50A8-2+J400 ====
VFDs from various manufacturers were considered during the evaluation process.  In particular, the following other drives were evaluated:
