🔋 Battery Storage Systems (ESS)
Store Your Solar. Take Control of Your Energy. Reduce Your Reliance on the Grid.
At Polaris Energy Solutions, we specialise in the design and installation of high-quality Solar PV and Battery Energy Storage Systems (ESS) for homes and businesses across Yorkshire.
A battery storage system allows you to store electricity when it is available or cheaper and use it when you need it most. When combined with solar PV, this can help you make much more of your own renewable energy instead of exporting excess generation to the grid.
We specialise in some of the leading battery storage technologies available today, including MyEnergi libbi, Sigenergy SigenStor and BYD Battery-Box systems.
Whether you're looking to add a battery to an existing solar PV installation, install solar and storage together, or build a larger, future-ready energy system, we can design a solution around your property, energy consumption and budget.
☀️ Why Add Battery Storage to Your Solar PV System?
Solar panels generate electricity during daylight hours, but much of a home's energy demand often occurs in the morning, evening or overnight.
Battery storage allows you to capture surplus solar generation and store it for later use.
Depending on your system and electricity tariff, your battery can also be programmed to charge from the grid during cheaper off-peak periods and discharge when electricity prices are higher.
🔋 Increase Solar Self-Consumption
Store surplus solar energy during the day and use it later when your solar panels aren't producing.
💷 Reduce Your Energy Costs
Use more of your own stored electricity and, where suitable, take advantage of cheaper time-of-use or dynamic electricity tariffs.
🌍 Make Better Use of Renewable Energy
Instead of exporting surplus solar generation, store it and use more of your own clean energy within your property.
⚡ Greater Energy Independence
Reduce your reliance on the electricity grid by generating and storing more of your own energy.
🔌 Backup Power
Selected battery and inverter combinations can provide backup power during a grid failure. Depending on the system selected, this can range from dedicated essential circuits to full-home backup and islanding capability.
We'll design the backup functionality around your requirements.
🚗 Ready for Future Energy Needs
Battery storage can work alongside other technologies such as EV charging, heat pumps and smart energy management systems, helping your home become more energy efficient as your needs change.
⭐ Our Battery Storage Specialisms
At Polaris Energy Solutions, we don't take a one-size-fits-all approach.
We specialise in three leading battery storage platforms:
⚡ Sigenergy SigenStor
For customers looking for an advanced, highly integrated and expandable energy system, we specialise in Sigenergy SigenStor.
SigenStor combines intelligent energy management with modular battery storage and can be configured to support applications including:
- ☀️ Solar PV
- 🔋 Battery storage
- ⚡ Intelligent energy management
- 🚗 EV charging
- 🏠 Home backup
- 📱 Smart monitoring and optimisation
The modular architecture allows storage capacity and system functionality to be tailored to the property, making SigenStor particularly well suited to customers looking for a future-ready energy system.
🔋 MyEnergi libbi
The MyEnergi libbi is an intelligent, modular home battery system designed to work alongside solar PV and the wider MyEnergi ecosystem.
libbi can store surplus solar generation and can also charge from the grid when electricity is cheaper, helping you make better use of time-of-use and dynamic tariffs.
The modular system is available in configurations from 5kWh to 20kWh, allowing the system to be sized around your property's energy requirements and expanded as your needs change.
libbi can also integrate with other MyEnergi products such as zappi EV chargers and eddi solar power diverters.
🔋 BYD Battery Storage
We also specialise in BYD battery storage systems, including the modular BYD Battery-Box range.
BYD is an established global battery technology manufacturer, with Battery-Box systems designed for use with compatible inverter platforms.
The modular nature of compatible BYD systems allows storage capacity to be configured to suit different properties and energy requirements.
🏠 Battery Storage for Existing Solar PV Systems
Already have solar panels?
You don't necessarily need to replace your existing PV system to benefit from battery storage.
We can assess your existing installation and determine the most appropriate approach for adding battery storage.
Depending on the existing equipment, we can consider AC-coupled, DC-coupled or replacement hybrid inverter solutions.
This makes battery storage a practical option for homeowners who installed solar several years ago and now want to get more from their existing PV system.
⚡ Smart Energy & Tariff Optimisation
Modern battery systems are about much more than simply storing solar energy.
With a compatible system and tariff, your battery can intelligently manage when electricity is stored and when it is used.
For example:
☀️ During the day
Solar generation supplies the property and surplus energy can charge the battery.
🌙 Overnight
The battery can potentially charge using cheaper off-peak electricity.
⚡ During expensive periods
Stored energy can then be used to reduce the amount of electricity purchased from the grid.
The exact savings and operating strategy depend on your electricity tariff, energy consumption, solar generation and battery system.
That's why we provide bespoke system designs and payback calculations rather than simply recommending the largest battery available.
🔌 Battery Backup & Islanding
For customers looking for additional protection against power cuts, we can design systems with backup functionality where supported by the selected battery and inverter equipment.
During a grid failure, a suitably configured system can disconnect from the grid and continue supplying power from the battery and solar PV.
This is known as islanding or backup operation.
Depending on the system, backup can be configured for:
- Essential circuits
- Selected sockets and lighting
- Dedicated backup circuits
- Full-home backup
Backup requirements are assessed during the design stage to ensure the system is correctly specified for the property and expected loads.
🚗 Integrate Your EV Charger
Battery storage can be incorporated into a wider smart energy system that includes electric vehicle charging.
We can design your system to prioritise your available solar generation and coordinate energy use between your:
☀️ Solar PV
🔋 Battery storage
🚗 EV charger
🏠 Home
⚡ Electricity grid
This can help you make greater use of your own renewable energy while reducing unnecessary grid imports.
♨️ Integrate Your Heat Pump & Smart Loads
Modern energy systems can also be designed around future technologies such as heat pumps and smart energy devices.
Depending on the equipment selected, additional smart controls can help monitor and manage energy consumption, allowing you to make better use of surplus renewable generation.
This creates an energy system that can evolve with your home rather than becoming outdated as your energy requirements change.
