Transformers – Voltage Conversion and Isolation

The transformers category provides voltage conversion and electrical isolation equipment for solar power systems requiring specific voltage levels or isolation from grid connections. Quality transformers deliver efficient power transfer between different voltage levels while maintaining electrical safety through galvanic isolation.

Modern transformers feature compact designs with high efficiency ratings, thermal protection, and appropriate power handling capacity for residential and commercial solar applications.

Transformer options include step-up transformers that increase voltage from inverter output to grid connection requirements, step-down transformers that reduce voltage for specific equipment needs, and isolation transformers that provide electrical separation without voltage change.

Auto-transformers offer efficient voltage adjustment for split-phase systems, converting between 120V and 240V configurations. Capacity ratings range from small 1kVA units for control circuits to transformers over 25kVA for whole-system power conversion.

Featured products accommodate single-phase and three-phase configurations with proper voltage ratings, frequency specifications, and temperature ratings for indoor or outdoor installations. Key specifications include primary and secondary voltages, kVA capacity, efficiency rating, and NEMA enclosure ratings for environmental protection.

Transformers integrate with grid-tied systems for utility interconnection, backup generator connections, and voltage matching between international equipment standards.

Transformer selection considers input voltage, desired output voltage, maximum power requirements, installation environment, and applicable electrical codes.
