Congsin Modified Sine Wave Inverter for Solar Off-Grid Systems
Overview
The Congsin modified sine wave inverter converts DC power from batteries or solar systems into usable AC power for off-grid homes, RVs, boats and work sites. Designed for simplicity and dependability, it delivers stable power to lights, small appliances, power tools and electronics where a pure sine wave isn't required.
Key Benefits
Practical and Affordable
This inverter offers a cost-effective way to get reliable AC power from your solar battery bank. It’s ideal for applications where budget and basic appliance compatibility matter more than the fine waveform needed by sensitive equipment.
Easy to Use and Install
Lightweight housing, clear LED indicators and straightforward terminals make installation fast for homeowners and installers. Compatible with common battery voltages and solar charge systems, it integrates well into existing off-grid setups.
Built-in Protections
Safety features include overload protection, short-circuit protection, low battery alarm/shutdown and over-temperature shutoff. These protections help extend battery life and safeguard connected devices.
Who Should Choose This Inverter
Choose the Congsin modified sine wave inverter if you need a reliable, economical power source for lighting, pumps, chargers, small kitchen appliances and workshop tools. It’s a strong option for RV travelers, cabins, field operations and construction sites where rugged, simple power is required.

FAQ
What is the difference between labeled 6000W and full power 3000W?
Labeled 6000W is peak power, which is only used to cope with the instantaneous high-power demand during device startup (such as air conditioner, motor startup); full power 3000W is continuous power, referring to the power that the device can stably output for a long time. When driving appliances daily, 3000W should be used as a reference to avoid total power overload.
Can it run inductive loads like fridges or tools?
Yes, pure sine wave output supports all load types.
Is the cooling fan noisy during operation?
The noise is low (≤45 decibels, equivalent to normal conversation volume). The fan uses a silent motor and automatically adjusts the speed according to the device temperature (low-speed operation when temperature <40℃, high-speed operation when >60℃), balancing heat dissipation and noise.
Does it have a charging (UPS) function?
No, this model is a pure inverter without UPS function.
