How do I size the PV array for an EOS solar pump?

The panel power sets the controller class. The 36-48 V configurations covered by the EOS 36-48/500 need an array of up to 500 W; the EOS 96/1000 accepts up to 1000 W. Flow varies with irradiation through the day.

Can the CFJ controller be used with non-solar JOVAL submersibles?

Yes. The CFJ is a hybrid VFD with MPPT that drives conventional three-phase pumps directly from the PV array. It is the way to solarise existing boreholes fitted with pumps from the JOVAL Submersible Pumps range.
