1500W off Grid Modified Sine Wave Inverter 12V DC to 220V AC

Product Description

Product Features

OPIM-1500 Modified Sine Wave Inverter

The OPIM-1500 modified sine wave inverter embodies the philosophy of "reliable quality and cost-efficiency"; the entire series holds CE, FCC, and RoHS certifications, meeting standards for export to Europe and the United States.

Each unit undergoes a 100% full-load burn-in test before leaving the factory to ensure stable and reliable performance during prolonged, high-load operation.

With over 22 years of experience in the R&D and manufacturing of power products, we maintain strict quality control over every stage of production.

The unit comes with an 18-month warranty, ensuring worry-free after-sales support.

Packaged at 6 units per carton, the product is convenient for wholesale and logistics.

Six-fold intelligent protection

Compact and lightweight

The OPIM-1500 features comprehensive built-in hardware protection mechanisms, ensuring worry-free operation:

Low-voltage protection: Triggers an audible and visual alarm if the voltage drops too low; automatically shuts down if the voltage continues to fall, protecting the battery.

Over-voltage protection: A red indicator light turns on and the output is automatically cut off if the input voltage becomes excessively high.

Over-temperature protection: Triggers an alarm if the temperature becomes abnormal; automatically shuts down if the temperature continues to rise, and resumes operation once cooled.

Short-circuit protection: A red indicator light activates and the unit shuts down immediately upon detecting an output short circuit.

Overload protection: Automatically shuts down if the load exceeds the rated power, preventing equipment damage.

The OPIM-1500 delivers a rated output of 1500W and a peak capacity of 3000W while featuring a compact form factor of just 285×155×80mm—making it 30% smaller and 45% lighter (at a net weight of only 1.94kg) than comparable pure sine wave products.

Its ultra-compact design facilitates easy in-vehicle transport and RV installation, while also significantly reducing logistics costs, making it ideal for cross-border e-commerce shipping.

It can be easily secured, whether placed in tight vehicle spaces or integrated into solar power systems.

Combining high power with portability, it offers greater freedom for mobile power usage.
