Provides Reliable, Independent Power for Home or Business
This pure sine wave hybrid inverter/charger intelligently manages power coming from your solar panels, batteries, and the utility grid all at the same time. It can allow for grid-tied operation and efficiently converts DC power from solar panels into AC power for immediate use or for energy storage in batteries, and vice versa. It converts stored power from any 24V DC battery source to network-grade AC power for sensitive electronics, including computers and laptops, network and audio/video equipment or office and household appliances. Recommended for rural and residential environments, telecommunications, gas and oil exploration, mining, forestry and other industries with remote sites. The APSWX2K24VMPPT is an excellent solution for energy savings in grid-tied and off-grid environments.

Optimal Performance of The Solar Energy System
With built-in MPPT (Maximum Power Point Tracking) the APSWX2K24VMPPT tracks and adjusts to the optimal point of power generation, resulting in increased energy production from the solar panels. This also improves the overall efficiency of the solar system, even in low-light conditions, resulting in consistent energy production throughout the day.

Priority Source Selection Allows Automatic Switching to Optimal Power Sources
The APSWX2K24VMPPT uses priority source selection to alternate between utility and solar power when charging batteries, depending on which is optimal at that time. When powering a 230V connected load, the inverter will alternate between utility and battery power. - An automatic overload detector, cooling fan and resettable AC circuit breakers help protect the unit from damage.

Works as an Inverter, Standalone Power Source or UPS System
An automatic line-to-battery transfer switch and built-in maximum power point tracking (MPPT) charge controller allow the APSWX2K24VMPPT to function as an inverter, standalone AC power source or extended-run UPS in environments with weak or unreliable solar or utility power. It delivers 2000W of continuous power and 4000W of peak power to handle high power draw during equipment startup or cycling. When used as a UPS, the APSWX2K24VMPPT responds to blackouts and brownouts with an automatic transfer to battery-derived AC output.

Input Terminals Allow Hardwired Installation
High-current DC input terminals allow hardwired connection to an external energy storage battery system. Designed for easy installation in rural or remote sites including residential, leisure, gas/oil and forestry the APSWX2K24VMPPT keeps the battery charged via the built-in AC and solar hybrid charging system while simultaneously delivering AC power to connected equipment. Pure sine wave power has less electrical noise and static for a clean signal that won’t damage equipment.

Enhanced Management and Safety Features
The front control panel with LCD provides real-time readout of all system functions and robust configuration options to meet the needs of your application. An on/off switch allows instant one-touch control over connected devices. A wired remote control is included, which lets you control the APSWX2K24VMPPT from up to 10 meters away. Five-way fault protection (high voltage, overload, overheat, short circuit, locked fan), an audible alarm and LEDs help increase operational safety.

Compatible with Photovoltaic Solar Panels
This pure sine wave solar inverter/charger works with photovoltaic (PV) solar panels, including single-crystalline, poly-crystalline with Class A rating and CIGS. For optimal performance, use “deep cycle” batteries with the APSWX2K24VMPPT, preferably wet-cell (vented), gel-cell/absorbed glass mat (sealed) or Lithium batteries.

Questions & Answers

An MPPT (Maximum Power Point Tracking) Solar Charge Controller is a device that regulates the voltage and current coming from the solar panels going to the battery. The primary function of an MPPT Solar Charge Controller is to ensure that your solar power system is operating at its maximum efficiency.

Solar panels can produce varying amounts of power depending on the intensity of sunlight, the angle of the sun, the temperature, and other factors. The power produced by a solar panel at any given moment might not be the ideal or maximum power that the panel is capable of producing. An MPPT controller solves this problem by continuously tracking the maximum power point of the solar panel and adjusting the voltage and current accordingly.

The advantage of using an MPPT Solar Charge Controller over a more traditional PWM (Pulse Width Modulation) controller is that MPPT controllers can convert excess voltage into amperage, allowing your solar power system to make use of a higher percentage of the power produced by the solar panels. This can result in a 15-20% increase in efficiency in winter and a 10-15% increase in efficiency in summer.

Moreover, the MPPT controllers can handle higher voltage input from solar panels, which can be beneficial for systems with long cable runs where voltage drop can be an issue. They can also accommodate for larger systems and different types of batteries, making them more flexible for various solar power system configurations.

A sine wave inverter is a device that converts DC power (like the power stored in a battery) into AC power (like the power used in your home). There are two types of inverters that are commonly used: pure sine wave inverters and modified sine wave inverters. Here's how they compare:

1. Pure Sine Wave Inverters

Pure sine wave inverters generate an output that is identical to the smooth, sinusoidal wave of AC grid power. This is the type of electricity you'd typically receive from an electrical outlet in a home or business.


  • Better compatibility with all kinds of devices, appliances, and technologies.
  • More efficient operation, less waste heat.
  • Reduced electrical and audible noise.
  • Better for motor loads and power tools as they run at the correct speed and do not overheat.
  • Essential for sensitive electronics and medical equipment.


  • More expensive due to complex technology.

2. Modified Sine Wave Inverters

Modified sine wave inverters produce a waveform that is more like a square wave, with sharp, flat plateaus instead of smooth, rolling waves. While these inverters can power many types of devices, they are less efficient and may not work well with certain types of electronics.


  • Generally cheaper and simpler design.
  • Suitable for many common appliances like heaters, fridges, or lights.


  • Less efficient, creating more waste heat.
  • May cause issues with certain sensitive electronics or appliances, causing them to run less efficiently or even damaging them.
  • Increased electrical noise can interfere with some systems.
  • May cause clocks and timers to run faster.

In summary, if you're using sensitive equipment or if you need your system to be highly efficient and reliable, you should use a pure sine wave inverter. However, if you're only powering basic appliances and are looking to save money, a modified sine wave inverter might suffice. But do keep in mind that the cost savings upfront might lead to higher energy costs or damaged equipment over time.
