Increase Inverter from 600 to 800 Watts: Is It Worth It?

Increase Inverter from 600 to 800 Watts: Is It Worth It?

As we step into 2024, the federal government’s new Solar Package 1 has officially increased the feed-in limit for balcony power plants, allowing for the upgrade of inverters from 600 watts to 800 watts. If you’re already an owner of a 600W balcony power plant, you might be wonder: Is it worth it to increase inverter from 600 to 800 watts?

This guide delves into whether upgrading your inverter from 600 to 800 watts is a beneficial move under the new regulations. We’ll look into the advantages of such an upgrade, recommend top-rated 800W balcony solar power systems, and discuss the regulatory implications of making this change. Join us and learn all the essential information to make an informed decision.

Already Have a 600-Watt Inverter, Do You Need to Upgrade?

If you’re already the owner of a 600-watt inverter, the decision to upgrade should be based on your energy needs and financial considerations:

Assess Your Energy Needs

First, consider your energy consumption. If your current setup consistently meets your power needs, upgrading might not be necessary. However, if you frequently experience power shortages or if your energy needs have increased—perhaps due to a growing family or adding more electric appliances—an upgrade could be beneficial. The additional 200 watts can make a substantial difference, allowing you to generate and use more solar power throughout the day.

Financial Considerations

If you have a 600W balcony power plant with WiFi-enabled inverters, upgrading your inverter from 600 watts to 800 watts could be as simple as performing an app update. This seamless transition does not require physical replacement of your existing inverter and comes at no additional cost—a straightforward and economical solution to increase your energy capacity.

If your system lacks WiFi capabilities, you have a couple of other options:

  • Add an Additional Inverter:You can supplement your existing setup by integrating an additional 200-watt inverter. This option allows you to boost your total output to 800 watts without having to replace your current inverter.
  • Replace the Inverter: Alternatively, you might consider replacing your 600-watt inverter with a new 800-watt model. This option is more invasive and may involve higher initial costs, but it could provide a more streamlined and potentially more efficient energy system.

While these options might include initial investments, you can harness more solar energy with a higher capacity inverter, which translates to lower electricity bills and more savings in the long run.

Advantages of Upgrading the Balcony Power Plant from 600 Watts to 800 Watts

Upgrading your balcony power plant from 600 watts to 800 watts offers several key benefits that can enhance both the efficiency and effectiveness of your solar power system. Here’s why you might consider this upgrade:

More Power Production

By upgrading to an 800-watt inverter, you significantly boost your system’s capacity for generating power. This increase allows you to capture and convert more solar energy throughout the day. Especially during peak sunlight hours, an 800-watt inverter can harness more power, which means you can produce more electricity than before. This is particularly advantageous for households with higher energy needs or those looking to maximize their solar investment.

Energy Savings and Lower Utility Bills

With greater power production comes the potential for enhanced energy savings. An 800-watt inverter enables your system to supply a larger portion of your home’s energy demands using solar power, reducing your reliance on the grid. This decrease in grid energy consumption directly translates to lower utility bills. Over time, the savings accrued from reduced energy costs can offset the initial expense of upgrading your inverter.

Better Support for Energy Demands

An 800-watt inverter provides enhanced capability to meet the demands of energy-intensive appliances and electronics in your home. Whether it’s running air conditioners, kitchen appliances, or multimedia systems, a more powerful inverter ensures that these devices operate smoothly without the risk of overloading the system.

This is particularly important during peak usage times, such as evenings or weekends when multiple devices might be used simultaneously. Upgrading to an 800-watt inverter ensures your power supply is more stable and efficient, offering peace of mind that your energy needs are securely supported.

800 Watts Balcony Power Plant Product Recommendation

If you’re considering upgrading to an 800-watt setup, the Anker SOLIX Balcony Solar Power System (2*RS40B Panel 410W, Micro Inverter 600W/800W, Balcony Brackets) is an excellent choice. This system includes two RS40B panels, each capable of producing 410 watts, along with a WiFi-enabled 800W micro inverter.

The solar panels of this system boast top-tier efficiency of 23%, meaning that more of the sunlight hitting your panels is converted into usable electricity. With a 25-year guarantee maintaining at least 84.8% efficiency, it ensures your investment is protected over a significant period, providing peace of mind along with consistent performance.

The all-black surface of the panels blends naturally with various architectural styles, making it a visually appealing choice for modern homes. Installation of the Anker SOLIX system is straightforward, designed to be completed within just two hours. This quick setup process minimizes disruption and allows you to start generating solar power without any complex procedures.

Additionally, the intuitive Anker app provides real-time and historical data on your energy production and usage. This feature enables you to monitor your system’s performance directly from your smartphone, making it easy to track your energy savings and assess the system’s health.

Do You Have to Register after Upgrading the Inverter from 600W to 800W?

In Germany, any modification that alters the power output of a solar system typically requires notification and registration with the relevant local or national energy authorities. This ensures that all systems comply with safety standards and grid requirements.

When you upgrade your inverter from 600W to 800W, you will need to inform your local network operator and update your registration on the Federal Network Agency’s Market Master Data Register (MaStR). This step is crucial for ensuring your system is legally compliant.

With new policies set to be implemented, you will no longer need to register such upgrades with the local network operator. This change aims to reduce bureaucratic hurdles and facilitate easier adoption of solar energy. However, you will still need to register the upgrade with the MaStR of the Federal Network Agency. This registration is crucial as it helps in maintaining an up-to-date record of all power-generating units in the country, ensuring grid stability and compliance.


As we’ve explored, if you decide to increase inverter from 600 to 800 watts, this upgrade offers numerous benefits, including increased power production, energy savings, and enhanced support for your household’s energy demands. We also took a closer look at the Anker SOLIX Balcony Solar Power System, which offers a practical 800W solution for those considering this upgrade. While it may require an initial investment, the long-term savings and improved efficiency can make it a worthwhile endeavor. So, take advantage of the new policy to enhance your solar power setup and enjoy the benefits it brings to the table.


What happens if my balcony power plant exceeds 600 watts?

As of January 1, 2024, if your balcony power plant in Germany exceeds the previously set limit of 600 watts, you can now legally increase its capacity up to 800 watts. This update to the regulations aims to facilitate more widespread use of renewable energy sources in residential settings.

How many modules does an 800-watt inverter have?

Typically, an 800-watt inverter can support around two to three solar panels, depending on their individual power output. It’s important to match the inverter size closely with the total panel output to avoid inefficiency or potential damage.

What can an 800-watt solar system do on a daily basis?

An 800-watt solar system can generate approximately 2.4 to 3.2 kWh of electricity on a daily basis, assuming an average of 3 to 4 hours of full sunlight per day. This amount of energy is enough to power small to medium-sized appliances such as LED lighting, laptops, refrigerators, or charge multiple small electronic devices. The actual output can vary based on factors like geographic location, weather conditions, and the efficiency of the solar panels.
