Tesla Powerwall 3
Ceiba Renewables is a Tesla Powerwall Certified Installer, and we are here to assist you with solar battery installations throughout Scotland.
Each customer receives a solar battery solution that is specially tailored to their requirements and expectations. Our solutions allow you to get the free and endless power of the sun, helping you reduce reliance on fossil fuels (which eventually will end), be more sustainable, save on rising energy costs, and ultimately save money.
With the Powerwall, you can store solar energy generated during the day for use at any time. During daylight hours, the sun shines on your solar panels, charging the battery. At night, your home draws electricity from the battery, enabling you to power your home with clean, sustainable energy around the clock.
Installing a Powerwall with Ceiba Renewables is a simple process. We handle everything from:
- system design
- installation
- commissioning
We can integrate the Powerwall with new solar systems, as well as with existing solar PV systems. The process is straightforward: just call us for an initial consultation. We will conduct a technical survey and provide you with a quote.
The Powerwall 3 offers a usable capacity of 13.5 kWh using Lithium Iron Phosphate (LFP) cells, which provide a longer lifecycle and better thermal stability. It features an active air-cooling system that utilises natural convection to cool the inverter, supplemented by a fan when needed.
With an integrated solar inverter, the Powerwall 3 allows easy connection to solar panels, improving efficiency and installation simplicity. Tesla’s software optimises energy usage based on home consumption and grid conditions, ensuring availability when needed.
The unit can be mounted on a wall or placed on the ground, indoors or outdoors, and connects to the grid to export excess energy for added economic benefits.
Powerwall can provide a number of benefits
- Increasing Self-Consumption of Solar Power: The Powerwall can store excess solar energy generated during daylight hours, allowing you to use that energy later when the sun isn’t shining.
- Load Shifting: The Powerwall can charge during off-peak hours, when electricity rates are lower, and discharge during peak hours, when electricity rates are higher.
- Back-Up Power: The Powerwall provides a reliable power source in the event of a grid outage. This feature is available as an optional extra.

The Tesla App brings you all the information about your Powerwall performance and allows you not only to monitor the performance of your solar and battery system but also programme off-peak charging.
The app has also been updated with more beautiful imagery with illustrative real-time power flow displayed on the Home Screen and simple graphs detailing the system’s production and consumption on the Energy Screen which allows you to analyse historical data.
Off-peak charging gives you the option to match the use of your store solar energy with your local pricing structure or even charge the Tesla Powerwall 3 with energy from the grid when it is cheaper. The owners can then edit the price schedule with peak and off-peak hours in order for the home battery pack to automatically optimise savings based on the schedule.
FAQ’s about Time-Based Control / Off-Peak Charging
Q. What is Time-Based Control?
Time-Based Control is an exciting feature that will allow Powerwall the ability to charge during the non-peak times, when electricity is less expensive so that it can power the home during peak times, when electricity is more expensive.
Q. But exactly how does it work?
Tesla’s Time-Based Control (Tesla’s name for Time of Use Load Shifting) allows owners to control Powerwall’s charge and discharge times via the Tesla app. Powerwall’s energy forecasting can learn the home’s production and consumption over time, allowing Powerwall to get smarter in how it charges and discharges.
According to their preference and goals, customers will be able to choose between three cycling modes:
- Self-Powered Mode (this is the standard mode, i.e. no off-peak charging)
- Time-Based Control – Balanced mode
- Time-Based Control – Cost Savings mode
Q. But what is a Time of Use rate plan?
The times of day when energy usage is highest is referred to as peak energy hours, these are the most expensive times to consume energy. These will typically occur when most people are home using appliances to power their home. The times of day where energy usage is low is called off-peak, this is typically in the night or early morning when people are asleep.
A TOU rate plan is structured around peak and off-peak times of day. Higher rates are charged at peak hours and lower rates are charged at off-peak hours. Under such a plan, a customer’s energy bill will be determined by not only how much energy they use, but when they use it.
Q. So how can Powerwall help the customer?
If the Powerwall knows the time of day that are considered peak and off-peak hours, it can be programmed to save the customer money. The Powerwall can be purposely charged with cheaper energy and then use it during peak hours, when energy costs the most.
Q. How does Energy Forecasting work?
With Time-Based Control, Powerwall uses an algorithm known as Energy Forecasting to learn the customers usage and supply power to the home when the customer wants it.
Powerwall will then use this smart technology to determine when to charge and discharge. Powerwall becomes smarter over time as it learns the energy habits of the customer and adapts accordingly.
Q. Which mode should I choose?
Cost-Saving Mode
The Cost Saving mode is the preferred selection for customers who are attempting to save the most money on their utility bill with a TOU rate plan.
- Charging priorities = Priority 1 is to charge from excess solar, priority 2 is to charge from off-peak rate.
- Discharging priorities = Priority is to discharge during on-peak hours
Balanced Mode
Balanced mode allows customer to maintain a good level of Self-Power for their home through Powerwall, while using stored solar to off-set their peak utility usage. This mode does not charge the Powerwall from off-peak rate, instead it ensures the solar battery doesn’t discharge during off-peak times in order to maximise savings during on-peak times.
Charging priority = excess solar only, Discharging priority = on-peak times only
As you can see from the two modes, the best option to maximise savings will be the Cost-Saving mode in many cases.
