What does a power inverter do?

A power inverter converts DC electricity from a battery bank or solar storage into AC electricity, enabling standard appliances and equipment to operate in off‑grid or backup power scenarios.

What is the difference between pure sine wave and modified sine wave?

Pure sine wave provides a cleaner waveform with wider compatibility for sensitive electronics and motor loads; modified sine wave is a more economical option for many basic appliances.

Which inverter is best for motors, pumps, or compressors?

A pure sine wave inverter is generally recommended, as it offers smoother motor operation and better compatibility, especially under high startup surge.

How do I choose between 12V, 24V, and 48V systems?

Match the DC input voltage to your battery bank. Higher DC voltages (24V/48V) reduce current and cable losses for larger systems, improving efficiency and safety.

Do you offer inverter‑chargers with UPS function?

Yes. Certain models integrate an automatic charger and UPS‑style transfer, allowing essential loads to continue running when mains power fails.

Do your solar inverters include MPPT or PWM controllers?

Yes. The category includes solar inverter solutions with integrated MPPT or PWM controllers and LCD displays for monitoring and configuration.

What protections should a quality inverter have?

Typical protections include overload, short‑circuit, reverse connection, over‑/under‑voltage, and battery‑related protections; exact thresholds and features depend on the model.

What AC output should I select (110V/120V/220V/230V/240V)?

Select the output voltage and frequency that match your local grid standard and connected equipment. Johsun Tec can tailor voltage and configuration to different regional markets.

Can you support OEM/ODM for distributors and brand owners?

Yes. OEM/ODM support is available for select models, including branding, configuration, and packaging tailored to your market and project requirements.

What information do you need to recommend the right inverter model?

Provide: (1) DC input voltage (12V/24V/48V), (2) required AC output (voltage/frequency), (3) continuous and surge load, (4) load types (motors vs. sensitive electronics), and (5) installation environment.
