Important Update for Huawei and iStore Battery Customers

Attention to all Huawei and iStore modular battery customers

An important announcement regarding the future of Huawei & iStore modular battery systems. Starting January 1st, 2027, batteries with 5kWh modules will no longer be expandable. It’s crucial for customers to understand the implications of this change.

 

December 31st Deadline to expand your modular Huawei/ iStore Battery System

No Future Expansions: After December 31, 2026, if you currently own an Huawei or iStore modular battery, you will not be able to expand its capacity. This limitation may impact your energy storage needs as your consumption patterns change over time.

Planning for the Future: Customers looking to increase their energy storage capacities should consider their options before the deadline. It may be an ideal time to reassess your energy needs and explore alternative battery solutions.

Evaluate Your Current Energy Storage Needs

Understanding your energy consumption is crucial, especially with the upcoming deadline to expand Huawei and iStore modular batteries. Here are several factors to consider when evaluating your current and future needs:

Monitor Your Energy Usage:

Begin by analysing your monthly energy consumption. Look at your electricity bills to understand your average usage in kilowatt-hours (kWh). Tracking your daily usage can also highlight peak times when you consume the most power.

Anticipate Future Growth:

Consider any upcoming changes that may affect your energy needs. Are you planning to: 

  • Add New Appliances: New appliances, particularly energy-intensive ones like air conditioners, electric heaters, or electric vehicles, can significantly increase your overall energy consumption. 
  • Expand Your Living Space: Home renovations or additions can lead to higher electricity demands. 
  • Energy-Intensive Activities: Activities such as starting a home-based business that requires additional equipment or appliances will affect your electricity usage.

Assess Your Lifestyle Changes:

If you expect changes in the number of people living in your home, such as children moving in or out, this could also impact your energy needs. More occupants often mean higher energy consumption due to increased usage of lighting, heating, cooling, and larger appliances.

Explore Larger Battery Options:

If your analysis indicates that your energy needs may surpass what your current battery can provide, it’s essential to consider expansion to increase your Huawei/ iStore battery capacity. As the battery is modular you can increase your battery size in 5kWh increments subject to local rules and regulations. Larger batteries can provide significant improvements in energy storage, allowing for greater self-sufficiency and reduced dependence on grid electricity. 

Evaluate Alternative Energy Sources:

Alongside considering larger batteries, explore other renewable energy solutions, such as: 

  • Solar Panel Enhancements: Upgrading your solar panels can increase the amount of energy generated, complementing your battery storage needs. 
  • Smart Energy Management Systems: These can help you monitor and manage energy usage more efficiently, potentially decreasing the amount of stored energy you need.

Consult with Professionals:

Engage with Solargain's experts for personalised assessments of your energy needs. We provide tailored recommendations based on your consumption patterns and future considerations, ensuring that you make an informed decision for both now and into the future.
