C.R.I.'s solar AC borewell submersibles are fully stainless-steel (304/316) multistage centrifugal pumps for 100 mm (4″) and 150 mm (6″) wells, from 1 to 10 HP with operating heads of 30 to 150 m and daily outputs up to 321,300 litres. Laser-welded impellers, water-lubricated bearings and dynamically balanced rotating parts back the range's reliability — C.R.I. has supplied over 40,000 MNRE-approved solar pumpsets.

The AC induction motors are rewindable — a practical maintenance advantage in rural areas — and run on solar power through C.R.I.'s Solar Pump Controller V4.0 (120–750 VDC input), cross-linked below. Output figures are rated at 7.15 kWh/m²/day average solar radiation with panel tracking.
