Upgrading Your System with Battery Storage

Grid-Tied With Battery: A Power Uprade

A grid-tied battery upgrade enhances your existing solar power system by incorporating advanced storage solutions. It not only converts and utilises solar energy but also optimises the storage of excess power for later use. Excess energy that would usually be sent back to the grid now charges your batteries, ensuring your essential loads remain functional during outages. This upgrade offers greater control over your home’s energy usage and potential for increased savings. Discover the seamless integration of battery storage into your grid-tied system and transform how your home utilises solar power.

Discover the seamless integration of battery storage into your grid-tied system and transform how your home utilises solar power.

SOLAR PANELS

Capturing Solar Energy

With a battery storage solution, your existing solar panels continue their crucial role by capturing sunlight and converting it into direct current (DC) electricity. This DC electricity powers your home and charges the battery, ensuring energy availability during peak usage times or grid outages. Efficient solar panels optimise the amount of electricity stored and later utilised, enhancing both energy reliability and independence.

Solar Inverter

Optimising Energy Conversion

In your upgraded grid-tied system, the solar inverter continues its essential role by converting direct current (DC) electricity from your solar panels into the alternating current (AC) needed for your home. With a battery storage upgrade, the inverter also manages the flow of electricity to and from your battery system, ensuring efficient use of stored energy. It automatically switches to battery power during peak demand times or when solar production is low, maximising savings and enhancing energy independence.

Energy Monitoring

Smart Management And Savings

Energy monitoring is essential for maximising the benefits of your solar + storage system. It provides real-time data on energy production, usage, and storage levels, empowering you to make informed decisions on effectively utilising your stored energy. By understanding your energy habits, you can adjust consumption to reduce reliance on the grid and increase savings. This smart management enhances the efficiency of your solar investment, ensuring you harness the full potential of every solar-generated electron.

The Grid

Efficient USE, Savings Opportunity

With our battery upgrade to your grid-tied system, you gain more than just backup power. The grid serves as essential support, efficiently utilising the energy your system generates. When your battery is fully charged and your solar panels continue producing energy, this surplus can be sent back to the grid. This not only reduces reliance on the grid during peak times but also offers the opportunity to receive credits for the extra power you supply. We ensure a smooth connection to the grid, maximising savings and enhancing the efficiency of your solar investment.

Battery Upgrade
Options:
AC vs. DC Systems

Elevating your solar power setup with a battery means choosing between two main types of systems: AC Coupled and DC Coupled. Each offers distinct advantages depending on your current setup and energy goals.

AC COUPLED
SYSTEM

For homes already harnessing solar power, the AC Coupled system is a compatible and efficient approach. It integrates with your existing inverter, making it easy to expand your setup with battery storage. While integration is generally straightforward, some adjustments may be necessary to ensure optimal performance and efficiency. These modifications aim to enhance your system’s capability, providing a streamlined solution for those keen to upgrade their solar infrastructure.

DC COUPLED
SYSTEM

Ideal for those installing solar panels and batteries simultaneously, the DC Coupled system is a model of efficiency. It links the solar panels and battery storage through a unified inverter process, streamlining energy conversion from sunlight to electricity. Perfect for new installations, it offers a neat, efficient package that optimises your energy use from day one.
