When installing a Tesla Powerwall 3 alongside a solar PV system, working with your local Distribution Network Operator (DNO) is essential. The DNO ensures your system complies with grid regulations, which can influence your battery settings and export limits. In Scotland, for example, the DNOs are SSE and Scottish Power. Below is an easy-to-follow guide on how DNO regulations like G98 and G99 may affect your installation.
What is the G98 Regulation?
The G98 regulation allows you to connect systems with an output of up to 3.68kW (equal to 16 amps) to the grid without prior approval or fees. This limit applies to both your solar panels and battery system combined, making it a simple and cost-effective option for smaller installations, combatting climate change.
Why Does the G99 Regulation Matter?
If your solar panels and battery system together exceed 3.68kW, you’ll fall under the more complex G99 regulation. Even if your Tesla Powerwall 3 doesn’t export energy to the grid, the DNO considers it part of your generation system. For instance, if you have both a solar PV array and an AC-coupled battery system, the combined power could push you into G99 territory, requiring approval.
Power During an Outage: The Role of “Islanding”
One key feature of the Tesla Powerwall 3 is its ability to keep your home powered during an outage, known as “islanding.” However, if your Powerwall is capable of islanding, your system automatically requires a G99 application, even if your system doesn’t exceed the 3.68kW limit.
How G99 Applications Work
A G99 application is required for any system that outputs more than 3.68kW per phase to the grid. Note that this applies to the continuous output from your battery (on the AC side), not the capacity of your solar panels or battery storage. The DNO can take up to 45 working days (around 3 months) to process your G99 application and provide an Offer Letter, detailing any associated costs. Sometimes, there are no fees, but additional costs such as admin fees, testing fees, or even network upgrades may be required.
DNOs interpret regulations differently, meaning costs can vary widely. Some applications are approved without any fees, while others may involve significant costs. This makes it difficult to predict the exact charges in advance. Thankfully, experienced installers like Ceiba Renewables often have good relationships with DNOs, which can help streamline the process and reduce costs, especially for witness testing.
What If G99 Costs Are Too High?
If the G99 Offer Letter is too expensive, there’s an alternative: designing the system with Export Limitation. This limits the output of your solar PV and Powerwall to 3.68kW each, which can sometimes avoid the G99 fees altogether.
The G99 Fast-Track Process
Some DNOs offer a G99 Fast-Track option for systems where both the battery and solar PV are capped at 3.68kW. This fast-track process has no fees and a quicker approval time, but its availability can vary. Crucially, the Fast-Track is not available for batteries that work during power cuts.
Choose the Right Output Setting for Tesla Powerwall 3
Option 1: Apply for the Full 11.04kW Output
One approach is to apply for the total 11.04kW output and see what the DNO says. While the DNO may impose fees or require a longer approval process, applying for the maximum output ensures that you future-proof your system for potential upgrades or increased energy needs. If approved, you can take full advantage of your Powerwall 3’s capabilities and maximize energy storage and output, especially in scenarios like energy trading or high-load usage.
Option 2: Size the Powerwall Output Based on Your Solar PV
Another strategy is to size the Tesla Powerwall 3’s output to match your solar PV output, which could make the approval process smoother and quicker. For instance, if your solar system produces around 7kW, you might choose a 7kW output setting for the Powerwall. This aligns the battery’s output with your solar generation, preventing unnecessary energy clipping and ensuring optimal energy use.
This option can also help avoid costly fees or lengthy approval processes, as the DNO may find it easier to approve a system sized to balance with the solar generation rather than maxing out at the 11.04kW setting.
Considering Solar Panel Orientation
The orientation of your solar panels plays a key role in determining the ideal output setting. For example, if your solar panels are spread across different roof angles, the peak output might be lower than the total kWp of your system. Matching the Powerwall 3’s output to the actual power your panels are capable of generating (up to 11.04kW) ensures the system operates efficiently without overloading the grid.
Comparing Discharge and Charge Rates
With multiple output options, it’s also important to consider the impact on discharge and charge rates. For example, if your battery discharges at 11.04kW, a fully charged 13.5kWh battery will last for around 1.2 hours under heavy load (13.5kWh / 11.04kW). In contrast, a 3.68kW setting would last approximately 3.66 hours under the same conditions, offering greater endurance but slower power delivery.
Choosing the right setting depends on how you intend to use the Powerwall. If fast charging during off-peak times is a priority, higher output settings like 10kW or 11.04kW could be advantageous. However, if you’re more concerned with extending battery life during power outages, a lower setting like 3.68kW or 5kW may be more suitable.
Which Setting is Best for You?
Ultimately, the right output setting for your Tesla Powerwall 3 depends on your unique circumstances. If you have a solar system that generates 4.5kW or more, applying for the 11.04kW setting may give you the flexibility to maximize energy usage. However, if you’re concerned about DNO approval times or fees, sizing the output to your solar PV generation (for example, 6kW or 7kW) may result in faster approval and fewer complications.
As always, you can work with your installer to adjust your settings if needed, and you can even reapply with different settings based on the feedback from the DNO.

UK’s Coal Energy Departure
On Monday, September 30, 2024, Ratcliffe-on-Soar Power Station in Nottingham ceased operations, marking a significant historical moment for the UK. After nearly 60 years of service, this is the last coal-fired power station still running in the country, and its closure signifies the UK’s complete departure from coal energy. This journey began with the Industrial Revolution.
From being a global pioneer in coal-powered electricity, the UK has now emerged as a leader in the transition away from coal power. It has become the first G7 nation to achieve this feat, a milestone reached after almost 150 years of coal use. This underscores the country’s unwavering commitment to greener energy and serves as a historic moment in the global move towards a cleaner, more sustainable future.
The journey began in 1882 when Thomas Edison built the world’s first coal-fired power plant in London, sparking the coal revolution. From that moment on, coal became a cornerstone of the Industrial Revolution for another 142 years, powering factories, homes, and transportation across the United Kingdom. (Molly Lempriere, 2024)
A Step Towards a Greener Future
Closing the last coal-fired power station in the UK is a significant step towards a greener and more sustainable future. With the transition from coal power, the renewable energy industry can improve and expand in several ways. This is a historic victory for British society, particularly for climate activists, according to Daniel Therkelsen (Gagliardi, 2024). Ceiba Renewables is committed to leading Scotland’s efforts to fight climate change and promote renewable energy. With the closure of Ratcliffe-on-Soar Power Station, there is an opportunity to further invest in and develop renewable energy sources such as wind, solar, and hydroelectric power. By expanding our renewable energy infrastructure, we can contribute to reducing carbon emissions and mitigating the impact of climate change.
We are human and we hold the power to drive the green energy revolution forward. We can make a significant contribution by considering a switch to renewable energy sources for our homes or businesses, such as installing solar panels or choosing energy providers that offer renewable energy options. Moreover, advocating for policies that support renewable energy development and promoting sustainable practices in our communities can further accelerate this transition.
By collectively embracing renewable energy and sustainable practices, we can create a better, greener future for our children and future generations, reducing environmental impact and combatting climate change.

At Ceiba Renewables, we’re excited to introduce the Tesla Powerwall 3 — a next-generation battery that not only eliminates rare earth metals but offers remarkable flexibility with its programmable inverter. This feature helps us navigate the unknowns of the G99 application process required by the Distribution Network Operator (DNO) when installing Powerwalls, ensuring your home can safely integrate with your home and disconnect from the grid during outages.
The Powerwall 3 charges at 5kW but can output up to 11.04kW to power your home from solar energy or export to the grid (subject to DNO approval). These capabilities optimise energy use, reduce grid dependency, and offer savings.
In this post, we’ll break down key design considerations to help you understand how the Powerwall’s settings work together to maximise your system’s efficiency.
Key Tesla Powerwall 3 Components
Solar PV kWp Rating
The kilowatt-peak (kWp) rating measures your solar panels’ maximum output under optimal conditions. A 6kWp solar system, for example, can produce up to 6kW in peak sunlight, helping meet your household power needs and storing excess energy.
G99 Setting: Battery Output to the House
The G99 setting determines how much power the Powerwall can send to your home & the grid. The Powerwall 3 can supply up to 11.04kW, but this will require approval from your DNO. Once the DNO have assessed the application, the output might need to be limited to 3.68kW, 5kW, 6kW, 7, 8, 9, 10 or 11.04kW to comply with DNO requirements.
G100 Export Limit Setting
The G100 limit governs how much excess energy can be exported back to the grid. Depending on local grid rules, this limit may be set at 3.68kW but could go as high as 11.04kW with DNO approval. Any solar energy produced beyond this limit is “clipped,” meaning it’s neither used nor exported.
Battery Charge Rate
The Powerwall 3 charges at a rate of 5kW, allowing it to efficiently store energy from solar panels or the grid for later use.
Real-World Example: Gerry’s Setup
Let’s take Gerry as an example:
- Solar PV Setup: 13.2kWp solar panels (10kW West-facing, 3.2kW South-facing).
- Powerwall 3: Storing excess solar energy.
- G100 Export Limit: 3.68kW.
Image: Gerry’s Solar System
On a sunny day, his panels might produce up to 13kW. The Powerwall charges at 5kW, leaving 8kW for household use or export. If Gerry’s home only uses 1kW at the time, 7kW is available for export, but due to the 3.68kW export limit, 3.32kW will be clipped.
Clipping: What It Means for Your System
Clipping happens when your system produces more solar power than can be used in the home and exported. In Gerry’s case, 3.32kW was clipped. Although this might sound like a loss, it only occurs during peak production meanwhile in lower light conditions the PV system can produce more power than a lower output system. Homeowners can also offset clipping by using excess energy for high-demand activities like charging an electric vehicle (EV). The Tesla Wall Charger and Zappi EV Chargers are ideal for this!
Future-Proofing Your Tesla Powerwall 3 Setup
To prepare for future energy needs:
- Cable Sizing: Use the right cables (e.g., 16mm² for an 11.04kW output) to handle future Powerwall upgrades.
- G99 Applications: To unlock the full 11.04kW output, you’ll need DNO approval. This process can take time and isn’t always guaranteed, but it can enhance your system’s flexibility and potential for financial returns, especially with energy trading.
When designing your Tesla Powerwall 3 system:
- Lower output settings ensure regulatory compliance but may limit energy use and exports.
- Higher solar PV ratings generate more energy but could lead to clipping during peak production.
- Your system’s settings will depend on your energy needs, local DNO requirements, and future goals.
Choosing the 11.04kW output option may require extra time for DNO approval, and we may need to resubmit applications if approval is denied.
We’ll tailor your Tesla Powerwall 3 system based on your specific needs and DNO limitations. Here’s an example of how your settings might look:

Solar PV and battery storage systems can be effectively implemented in a variety of agricultural settings and operations:
- Irrigation and Pumping Systems: Solar PV systems can power electric pumps for irrigation systems, ensuring consistent water supply and reducing reliance on diesel-powered generators. Battery storage systems can store excess solar energy for later use, enabling operation during evening hours or periods of cloud cover.
- Greenhouses: Solar PV and battery storage can supply electricity for heating, ventilation, and artificial lighting systems within greenhouses. This allows for improved energy efficiency, reduced operational costs, and a more sustainable agricultural environment.
- Livestock Facilities: From milking equipment to temperature control and lighting, solar PV and battery storage systems can help power energy-intensive livestock facilities. By powering these operations with clean energy, farms can enhance both animal welfare and environmental sustainability.
- Remote Locations: Farms often have remote locations that require electricity for security systems, lighting, or monitoring equipment. Solar PV and battery storage systems can provide an independent and reliable source of energy for these off-grid locations, eliminating the need for costly grid connections or fuel-powered generators.
