What Does a Power Inverter Do?

An inverter converts direct current, usually from a battery, into alternating current used by many household devices.

Safety note: Electrical work can cause shock, fire, equipment damage, or utility hazards. Use qualified professional help for household wiring, transfer equipment, and any grid connected work.

Power rating

An inverter has limits on continuous and surge output. Connected loads must stay within the manufacturer',s specifications.

Waveform

Pure sine wave inverters are designed to provide a waveform suitable for a wide range of electronics and appliances. Compatibility still depends on the equipment.

Battery side matters

Higher AC loads require substantial current from a low voltage battery bank. Cable sizing, fusing, connections, and battery capability become critical.

Professional help

Permanent connections to household circuits can involve electrical code, permits, transfer equipment, grounding, and other requirements. Use a qualified electrician for that work.
