[RE-wrenches] High-Voltage MPPT Charge Controller Needed

[Exeltech]

Wrenches,

Does anyone know of a good quality temperature compensated, three-state charge controller capable of working with a 360 volt battery system?  (An equalize mode is also highly desired.)

The battery consists of 30 series-connected 12V, 260 A-H deep-cycle sealed lead-acid batteries connected to a 277/480V three-phase inverter in a commercial application.  The owner would like to charge the battery with a PV array, not the grid.  Subsequently, the controller would need to be capable of working with PV providing up to 600Vdc input to the controller.  The PV array does not yet exist, but will be designed to match the controller.

Replies on list are acceptable.


Thank you.
