Description

California Instruments SQ0022 Grid Simulator Repair and Calibration

The California Instruments SQ0022 is a regenerative grid simulator — a programmable AC source built to emulate grid conditions (sags, swells, frequency shifts, harmonics, phase imbalance) for testing inverters, EV chargers, and grid-tied equipment, with the ability to sink regenerated power. As a high-power programmable AC system, its faults concentrate in the power stage, the regenerative/control electronics, and waveform generation.

June Company repairs and calibrates the California Instruments SQ0022 for grid-tie, inverter, and EV test labs.

Common SQ0022 problems we fix

Output stage won’t reach setpoint — power-stage failure, rebuilt so it sources programmed voltage, frequency, and current.
Regenerative / sink mode faults — the bidirectional power electronics, repaired and verified.
Waveform or grid-condition emulation off — waveform-generation faults that corrupt sag/swell/harmonic profiles, corrected.
Regulation or measurement drift — recalibrated against standards.
Cooling or control-interface faults.

FAQs

My grid simulator won’t emulate conditions correctly — fixable? Yes. Waveform and power-stage faults are repairable, then verified so it reproduces grid profiles accurately, with a NIST-traceable certificate.

Is the regenerative mode verified? Yes — both source and sink operation are checked.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
