A battery upgrade can help an existing solar installation serve more of the property’s evening demand or support essential loads. The right approach depends on the equipment already in place. Kodak, KOYOE, IMEON Energy and Megarevo systems have different voltage families, controls and communications requirements, so start with the installed model and what you want the upgrade to achieve.
For a new system, choose the battery and inverter together. For an existing installation, establish what can be retained and what may need updating. A complete proposal should connect those equipment choices to your load profile, backup priorities and future plans, with a clear scope for installation and commissioning.
Kodak: identify the inverter generation and interface
When upgrading a Kodak system, identify the inverter series and generation first. The Axpert/Kodak King interface has its own setup requirements; another Kodak-branded unit may use a different arrangement. Use the equipment nameplate, manual and commissioning record to establish the model before selecting a Freedom Won battery. Find Freedom Won’s interface resources.
For an upgrade, explain whether the existing system is supplying an off-grid property or providing selected backup loads. Include the previous battery type and the reason for replacing it. The installer can then assess the inverter’s supported communication and operating limits against the proposed Freedom Won battery. The useful outcome is an identified, documented combination with a clear commissioning responsibility.
Do not judge compatibility by the physical appearance of a communications socket. A cable that fits does not establish the correct wiring or protocol. Ask for the required accessories to be included explicitly in the proposal so that the installation is not delayed by a missing interface component.
KOYOE: separate low-voltage and high-voltage enquiries
KOYOE systems include low-voltage and high-voltage arrangements, which need different battery selections. Provide the full inverter model, series and rating so the battery can be matched to the correct architecture. For an existing installation, include the current battery details and any proposed increase in demand.
The distinction has practical consequences for future upgrades. A battery family chosen for one voltage architecture cannot be assumed to transfer to a different inverter later. If expansion or a larger three-phase system is part of the longer-term plan, ask the designer to show the supported pathway and any equipment that would need replacement.
A new-system proposal should identify the actual battery and inverter models, the supported configuration and who will commission the combination. For an existing system, check the installed hardware and firmware before deciding which equipment to keep. These details help you compare the full cost and scope of an upgrade.
IMEON Energy: treat generation and battery approval as part of selection
With IMEON Energy equipment, inverter generation is part of battery selection. Hardware revisions can change the requirements for lithium storage, even when the product names look familiar. Confirm the installed generation and supported battery combination before finalising the upgrade. Read IMEON’s battery guidance.
Bring the IMEON model and serial details, together with the installed software information, to the technical discussion. The project team can then identify the battery profile, communications accessories and commissioning checks for the proposed combination. This helps ensure that monitoring and operating limits are coordinated across the system.
For the owner, the benefit is a clearer handover. The monitoring display should have an agreed meaning, the operating reserve should be understood and the service contact should know the installed configuration. Those details help the system remain useful when a household’s demand changes or servicing becomes necessary.
Megarevo: match the application as well as the voltage
Megarevo’s low-voltage residential inverters and MPS microgrid products serve different applications. A home focused on evening solar use and a commercial microgrid coordinating several energy sources need different designs. Choose the family around the site’s operating requirements, then confirm the specific battery interface. View Megarevo’s low-voltage range and MPS information.
A useful enquiry describes the phase arrangement, existing solar and whether a generator forms part of the site. It also identifies the most important load. A workshop seeking production backup needs a different assessment from a household mainly interested in evening solar use, even if both start by comparing similarly rated products.
Ask the proposal to state which equipment controls the system and what happens when the battery reaches its operating reserve. The answer should be explained in terms the owner can use, with detailed configuration left to the qualified project team.
Turn the load list into a meaningful energy budget
A simple example illustrates the process. A 600W continuous load running for ten hours uses 6kWh. Adding a 2kW appliance for one hour adds another 2kWh, giving 8kWh at the loads. These are illustrative figures, calculated by multiplying power by time. They exclude system losses and any battery reserve.
When both loads operate together, the power requirement is at least 2.6kW before other demands are considered. Equipment starting characteristics may add another constraint. This is why the same daily energy use can lead to different inverter choices. Our battery sizing guide provides a fuller explanation without turning the example into a product recommendation.
Make the quote easy to compare and maintain
Ask each supplier to identify the battery and inverter by full model code, explain the supported operating mode and list the assumptions used for runtime. Include communications accessories, monitoring, installation responsibilities and commissioning in the comparison. A short quote containing only two brand names can conceal important differences in scope.
Request a documentation pack at handover. It should include the equipment schedule, relevant manuals, a record of the commissioned arrangement and the appropriate service contacts. The owner should understand what normal operation looks like and whom to call when something differs. Keep those records available for a future installer or a planned expansion.
Explore the Freedom Won options with local context
Our eTower guide and LiTE Home guide help explain product selection. The compatibility page and download centre provide the next technical resources. Treat each battery generation as a specific product, with its own current documentation and supported integration.
To discuss an existing Kodak, KOYOE, IMEON or Megarevo system, contact Freedom Won Australia with the equipment details and your location. Describe what is working well, what you want to improve and any planned new loads. That gives the product and solution-provider discussion a practical direction: storage selected for the real system and a clear route from enquiry to an informed purchasing decision.
Frequently asked questions
Can a communications cable alone establish compatibility?
No. A matching connector does not establish the correct wiring, protocol, battery profile or supported operating configuration.
Why does inverter generation matter?
Hardware and communication capabilities can differ between generations. Identify the exact installed model and use its relevant documentation.
What should a battery-upgrade quotation include?
It should identify the battery and inverter models, required accessories, operating assumptions, commissioning scope and support responsibilities.
