Product Overview
If you are looking for a reliable and efficient way to convert 12V DC power to 120V AC power, the SUNGOLDPOWER 4000W 12V Pure Sine Wave Power Inverter is an excellent choice. It is a combination of an inverter, battery charger and AC auto transfer switch which make it a great value for money. The low frequency, low Idle Current, BTS cable, remote control make it easy to install and use in any application.
The 4000W 12v inverter requires a 120VAC input and can provide 120VAC output power for the appliances, and it can output 50 or 60Hz via the SW4. One of the most impressive features of this product is the adjustable charging current you can adjust the max charge current from 0 100 using a linear switch. This feature makes it easier to customize the charging process according to your needs.
Another highlight of this product is its AC/battery priority feature by default, the inverter is designed with AC priority but you can easily switch to battery priority using the SW5 switch. This allows you to prioritize either your AC or battery power depending on your requirements. The auto Gen Start feature is also very impressive as it enables the inverter to start up a generator when battery voltage goes low and turn off after battery charging is finished.

The item weight of 62 pounds and dimensions 25.6 x 109.2 x 90 inches make this product easy to carry around or store in any location without taking up too much space. The tech support provided by SUNGOLDPOWER also makes installation and use of this product seamless and hassle free.
In conclusion, I highly recommend SUNGOLDPOWER 4000W 12V Pure Sine Wave Power Inverter due to its reliability, efficiency, adjustable charging current, AC/battery priority feature and auto Gen Start feature that make it an ideal choice for anyone looking for an effective way to convert their 12V DC power into 120V AC power at an affordable price point.
