Use our solar DC to AC conversion calculator to convert the DC (direct current) power into usable AC (alternating current) power.
Note: 1000Wh = 1kWh and most inverters are about 90% efficient. But to check the exact value, have a look at the specs of your inverter.
DC watts: These can be the watts produced by your solar panels or the total capacity of your battery in Watt-hours to figure out how much actual power you have stored to run your household appliances.
Inverter Efficiency: Read the product description or specs sheet on your inverter (usually located at the bottom side). it''ll be mentioned as inverter efficiency rate (e.g 90%). Then enter 90 in the calculator.
like I have two 200W portable solar panels which produce about 1500 watts of total power in a day (1500Wh) and I have a 1000 watt pure sine wave inverter (with 90% efficiency rate) to run my AC appliances.
1500 DC watts will be equal to 1350 AC watts when using a pure sine wave inverter (90% efficient).
But most of our household appliances are designed to be run on Alternating current – AC (120-240V). So there will be a power loss when converting DC into AC with the help of an inverter.
To calculate the DC watts into AC watts use this formula:
Calculate DC amps into AC amps using this formula:
When converting DC watts into AC watts there will be a conversion loss of 5-15% because of the inverter efficiency rate.
Internal temperature and standby power consumption of an inverter is the reason for their less efficient rate.
And also using the wrong size wire will cause some power loss because every size wire is designed to handle a limited amount of current.
So make sure to use the correct size wiring between the battery bank to the inverter.
Use this chart to select the right size wire from the battery bank for your inverter.
Here''s a chart of DC watts into AC watts conversion with a pure sine wave inverter and modified sine wave inverter.
Note: the above table is based on a 90% efficient inverter.
With the help of this simple calculation formula, you can easily calculate the DC watts of your battery bank or solar panels into AC watts.

The primary purpose of solar inverters: converting the direct current (DC) generated by solar panels into alternating current (AC) that can be utilized to power our home appliances. So, let us break down solar inverters and their critical function in solar energy conversion.
Direct current (DC) electricity is generated by solar panels. Direct current (DC) is the direct movement of electrons in a single direction, much as how a river flows in a straight line. Contrarily, the energy we consume in our homes and workplaces comes in the form of an alternating current (AC) current, in which the motion of electrons frequently reverses direction, much like the ebb and flow of the tides.
Conversion Process from DC to AC
Consider the solar inverters as a translator, converting the language of electricity into one that we can comprehend and use.
1. DC Input: The solar panels absorb sunlight and produce DC electricity. This energy flows to the solar inverter.
2. Inversion: The solar inverter works its magic by using sophisticated electronics to flip the DC electricity into AC. This process involves creating a sinusoidal waveform, similar to the smooth, oscillating motion of a pendulum.
3. Grid Connection: In grid-tied systems, the AC electricity generated by the inverter is either used to power your home or sent back into the grid, depending on your energy needs and local regulations.
1. Grid-Tied Systems: In grid-tied systems, solar inverters connect your solar panel system to the utility grid. Surplus solar energy can be put back on the grid, paying you credits or lowering your power bill. This grid integration assures a consistent power supply, although yoursolar panels aren’t producing enough electricity (for example, at night or on cloudy days).
2. Off-Grid Systems: In off-grid systems, solar inverters are a vital component that helps store excess energy in batteries. This stored energy can then be used when the sun isn’t shining, making off-grid living or remote power generation possible. Off-grid inverters must efficiently manage the energy flow to ensure a stable power supply.
Not all inverters for solar energy are the same. There are various optionsto pick from, each with their own set of benefits and best-use scenarios:
1. Central Inverters: These types of inverters are commonly used in large-scale solar systems. They centralize the inversion process for the entire solar array. While cost-effective and efficient, they may experience reduced performance if a single panel is shaded or malfunctions.
2. String Inverters: In residential and small commercial installations, string inverters are popular. They group several solar panels together in “strings” and connect them to a single inverter. This setup is cost-effective and allows for easy monitoring of each string’s performance.
3. Microinverters: Microinverters are attached to individual solar panels, providing maximum efficiency and flexibility. They are an ideal choice for systems with shading issues or panels facing different directions. Each panel operates independently, ensuring optimal performance.
When talking about solar inverters, efficiency matters. Energy can be wasted as heat during the direct current (DC) to alternating current (AC) conversion process. As a result, selecting a high-efficiency solar inverter is critical for maximizing the power.
Improving solar inverter power quality of the system is also ensured by solar inverters. They make sure a consistent and clean power supply by stabilizing the AC output. This helps protect your appliances and prevents voltage fluctuations that can damage sensitive electronics.
