Congsin Modified Sine Wave Inverter 12V — Reliable DC→AC Power Solutions

Congsin Modified Sine Wave Inverter 12V — Reliable DC→AC Power

Overview

Our modified sine wave inverter 12V family converts 12V DC into stable AC power ideal for many common appliances and tools. Designed for dependable everyday use in vehicles, RVs, trucks, off-grid cabins and portable workstations, Congsin units emphasize reliability, affordability and ease of installation.

Key Features

Each modified sine wave inverter 12V model delivers robust protection and practical features: overload and short-circuit protection, low-battery shutdown, thermal management, multiple AC outlets and USB ports on selected units. Built on fully automated production lines and tested with advanced instrumentation, Congsin inverters offer consistent performance and long service life.

Applications

Perfect for resistive and many inductive loads, our modified sine wave inverter 12V solutions power lights, fans, small power tools, chargers and entertainment devices in automotive, camping, construction and field patrol scenarios. For sensitive electronics (medical devices, some motors and high-precision equipment), consult product specifications or consider a pure sine wave alternative.

FAQ:
Can I order samples before production?

Yes, we offer sample evaluation and prototype testing.

What power appliance can this inverter run?

It has a continuous power of 800W, so it can run appliances within 800W; the peak power is 1500W, supporting the instantaneous startup of appliances within 1500W.

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

Pure sine wave inverter has an output waveform close to mains power with low distortion rate (<3%), which can be safely adapted to precision devices such as computers, medical instruments, and inverter home appliances; modified sine wave inverter has a notched waveform, which easily causes device heating, malfunction or damage, and is only suitable for simple devices such as bulbs and fans.

What capacity battery is needed to meet long-term use?

It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
