PSW7 230V AC Power Inverter Charger – FoxPower

The PSW7 is a 1kW–6kW low-frequency pure sine wave inverter charger combining inversion, battery charging, and AC auto-transfer switching in a single unit. Conversion efficiency reaches 88%. The system supports 12–24 VDC input and delivers 230VAC output with integrated surge capacity for high-inrush loads.

MAIN IMAGE

The PSW7 integrates three core functions: DC-to-AC power inversion, battery charging from AC mains, and automatic AC source switching. This eliminates the need for separate components in off-grid and backup power applications.

Key operational features include low quiescent current draw, power-saver mode for reduced standby consumption, automatic generator start capability, and LED status indication. Optional RS232 communication and LCD display modules enable remote monitoring and configuration.

The unit supports low DC voltage operation suitable for residential and commercial applications. Surge capacity allows startup of motors and compressors without load shedding.

APPLICATIONS

Primary use cases.

Residential Off-Grid Systems

Provides primary AC power conversion and battery management for homes without grid connection or during extended outages.

Commercial Backup Power

Supports critical loads in offices and small commercial facilities with automatic switchover from mains to battery-backed inverter output.

Remote Installations

Enables standalone operation in locations with unreliable or absent grid infrastructure, paired with solar arrays or generator sets.

TECHNICAL FAQ

Common specifications and regulatory inquiries.

What is the difference between low-frequency and high-frequency inverter design?
Low-frequency inverters use larger transformers for output isolation, providing higher surge capacity and better tolerance of inductive loads. High-frequency designs are more compact but may have lower surge ratings. The PSW7 employs low-frequency topology.
Can the PSW7 operate in parallel with a generator?
Yes. The integrated AC auto-transfer switch enables seamless switching between mains AC and inverter output. Optional automatic generator start function initiates backup generation when battery voltage drops below a set threshold.
What does 'power saver mode' accomplish?
Power saver mode reduces quiescent (idle) current draw when the inverter is operating but supplying minimal load. This extends battery runtime during low-demand periods.
Are remote monitoring options available?
Yes. Optional RS232 communication module and LCD display enable remote status monitoring and parameter adjustment via compatible control systems.
What load types can the PSW7 start?
Integrated surge capacity allows the unit to start motors, compressors, and other inductive loads without load shedding. Specific surge ratings depend on the selected power rating (1kW–6kW).
