500W Modified Sine Wave Inverter for Car & RV | Congsin

500W modified sine wave inverter for car and RV — Reliable mobile power by Congsin

Overview

The 500W modified sine wave inverter for car and RV from Congsin converts 12V DC battery power into stable AC output to run small appliances, chargers and tools on the road. Designed for everyday mobile use, this compact inverter balances cost-efficiency and dependable performance for campers, vanlifers, technicians and emergency kits.

Key features

Built for practicality, the inverter delivers 500W continuous output with short surge capacity for startup loads. Typical specifications include 12V DC input to 110/120V (or 230V variant) AC output, multiple protection circuits (overload, over-temperature, low-voltage shutdown and short-circuit), LED indicators and quiet cooling. The modified sine wave topology supports most resistive and inductive devices—phones, laptops, small kitchen appliances, power tools and entertainment gear—while keeping production costs competitive.

Applications

Ideal for car and RV owners, this inverter is perfect for weekend trips, tailgating, field maintenance, and backup power during outages. Its compact footprint and vehicle-friendly connection options make installation straightforward in cars, RVs, trucks and boats. Whether charging devices at a campsite or powering a CPAP briefly, the inverter provides trustworthy on-the-go energy.

Safety, quality and compliance

Congsin integrates robust safety controls and rigorous testing on fully automated production lines to ensure product reliability. Our quality system is ISO9001 certified, and many models hold international approvals such as CE, EMC, LVD, ETL, FCC, RoHS and E-MARK. Built-in protections and intelligent monitoring help safeguard both your vehicle battery and connected equipment.

FAQ:
Is it compatible with both 12V and 24V vehicles?

Yes, it supports DC12V/24V dual input.

What is the function of the independent control switch?

The independent control switches for DC and AC can respectively control the on and off of DC and AC circuits, facilitating the separate management of power supply for different types of devices and improving power usage safety and flexibility.

Can this inverter drive a 3P air conditioner and a refrigerator at the same time?

Yes. The rated power of a 3P air conditioner is about 2200W-2500W, and an ordinary double-door refrigerator is about 150W-300W, with a total power of about 2350W-2800W, which does not exceed the 3000W continuous power; and the peak 6000W can cope with the instantaneous startup impact of the air conditioner. When using, ensure the battery capacity is ≥200Ah (12V) to ensure battery life.

What capacity battery can be used with it?

It is recommended to use a 12V 100Ah-200Ah lead-acid battery or lithium battery; the larger the battery capacity, the longer the UPS power supply time (e.g., a 100Ah battery can support a 100W device to work continuously for about 10 hours).
