How much power does a 12V inverter use?
For example: If you're running a 1500W inverter on your 12v battery with 1000 watts of total AC load. So your inverter will be consuming 83 amps (amps = watts/battery volts) from the battery for which you'll need a very thick cable. using a thin cable in this scenario can damage the inverter or you'll not be able to run your load.
How much power does a 24V inverter use?
A 24V inverter draws 9.6 watts with no load. This is calculated by the formula: Power drawn = Voltage * No load current (0.4 watts). This calculation applies to all inverters, regardless of their size. The voltage (12V or 24V) affects the no-load current, with higher voltages resulting in greater no-load current.
How many watts is a 120 volt inverter?
But on the 120-volt side of the inverter you get 1,200 watts coming out, which works out to 10 amps x 120 volts = 1,200 watts. It works out to an approximate 10:1 or 1:10 conversion factor depending if you’re converting from 12 volts to 120 volts, or 120 volts to 12 volts.
What is the no-load power of my inverter?
You can find no-load power (watts) mentioned on the specification sheet. To determine how much power your inverter is drawing without any load, multiply the battery voltage by the inverter no load current draw rating. For example, Battery voltage = 1000 watts Inverter = 24V
How many amps does a 1200 watt inverter draw?
A 1200 watt inverter would draw 120 (60) Amps at full load. This is equivalent to the current drawn by a 1200 watt inverter at its load capacity.
How much power does an inverter draw without a load?
To find out how much power your inverter draws without any load, multiply the battery voltage by the inverter's no load current draw rating. For example, if the battery voltage is 24V and the no load current is 0.4A, then the power drawn would be 24V * 0.4A = 9.6W.
Featured Solar Products

They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit.

They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
What Inverter Size Do I Need to Run an Air Compressor?
