10 Best Inverters With Built In Chargers 2025 in the United States

The Victron Energy MultiPlus-II 2X Pure Sine Wave Inverter Charger is a robust option for those in need of a reliable power solution. It offers a significant power output of 3000 watts, which makes it suitable for demanding applications. The device is compatible with 12-volt batteries and provides a substantial charging capacity of 120 amps, ensuring quick and efficient battery charging.

Additionally, the pure sine wave output ensures that sensitive electronics run smoothly and efficiently without risk of damage. This inverter charger is particularly beneficial for professional use in marine, yachting, vehicle, and off-grid applications due to its durability and high performance. One of its standout features is the Power Assist function, which prevents overloads by seamlessly managing the power supply between the grid, generator, and battery. The ability to operate in parallel with up to six units and configure for three-phase output adds flexibility for larger setups.

Another advantage is its quick activation during a grid failure, switching to battery power within 20 milliseconds to keep your systems running uninterrupted. However, the product's complexity might be a drawback for some users, especially those unfamiliar with advanced inverter systems. Additionally, the size and weight (24.04 kg) could be a consideration for those with limited space or who require portability. Despite these potential challenges, the Victron Energy MultiPlus-II 2X stands out for its high efficiency, versatile usage, and reliable performance, making it a strong choice for advanced power needs.

The SUNGOLDPOWER 10000W DC 48V Solar Inverter offers a robust power output of 10,000 watts, making it suitable for substantial home energy needs. It's equipped with built-in chargers and can handle a maximum battery charging capacity of 200A, which is quite impressive. The inverter provides pure sine wave output, ensuring stable and efficient operation for sensitive electronics. It supports various battery types, including AGM, Gel, Flooded, and Lithium, offering flexibility for users with different battery preferences.

Additionally, it has user-friendly features like WiFi connectivity to monitor performance via a mobile app and the ability to parallel up to six units for expanded capacity. The built-in MPPT solar controllers help to maximize the efficiency of solar panels by tracking the optimal power point, enhancing energy management. The inverter also comes with multiple charging modes and output configurations to suit different usage scenarios. Safety measures are robust with over-voltage, over-current, and overload protections.

The time-slot charging/discharging function allows for strategic energy use based on peak and off-peak tariffs, which can lead to cost savings. However, at 53.5 pounds and relatively large dimensions, it might be cumbersome to install for some users. This inverter is a powerful and versatile choice for those who have significant energy needs and value the flexibility of various battery configurations and charging modes, but potential buyers should consider the size and weight constraints.

The Xantrex Freedom SW3012 is a robust inverter and charger that offers 3000W continuous power, making it suitable for powering multiple devices or equipment simultaneously. One of its standout features is the true sine wave output, ensuring stable and consistent power similar to what you get from the grid. This is particularly beneficial for sensitive electronics that require clean power.

The unit is compatible with various battery types including LiFePO4, Flooded, Gel, and AGM, which provides flexibility depending on your existing setup or future needs. Additionally, it has a wide operating temperature range and temperature-compensated charging, making it reliable in different climate conditions. The built-in transfer switch facilitates seamless power transition between the inverter and incoming AC power, which means connected devices experience minimal disruption during power switches, enhancing reliability.

However, the unit is fairly heavy, weighing around 73.7 lbs., which might make installation and handling a bit cumbersome. Furthermore, while it is sophisticated and versatile, the advanced features might require a learning curve for optimal configuration. Another point to consider is its relatively high no-load power draw of 3 Adc during inverting, which could affect efficiency if used continuously without proper load management. The Xantrex Freedom SW3012 is a powerful and versatile inverter/charger ideal for users who require reliable, stable power with extensive battery compatibility, but it does come with considerations regarding weight and complexity.
