Congratulations on your purchase of the KODAK Off-Grid Solar Inverter! To ensure a successful installation, there are several key considerations and steps you should follow. Here is a step-by-step guide:
1. Battery Design: The battery bank is a crucial aspect of your system. It must be able to supply the expected loads and accommodate the wattage of your PV array. If the battery bank is too small, it can cause nuisance tripping and component damage. Avoid relying on the PV array or grid to support a small battery bank, as these sources may not be reliable. It is recommended to have the inverter or AC protection trip first in case of overloads, rather than relying solely on the battery BMS system.
2. PV Design: Pay attention to the voltage of your PV panels. The voltage written on the panel is only accurate at 25 degrees Celsius (STC). In colder temperatures, the open circuit voltage will increase. Always consider the coldest temperature when designing your PV array to avoid potential failures, such as MPPT issues during winter.
3. Overload Protection: Design the AC protection to accommodate potential overloads, rather than relying solely on the inverter or batteries. It is easier and safer to reset a breaker than to restart the entire PV system. Consult the breaker documentation to determine the desired characteristics for protecting your inverter.
4. AC and DC Surge Protection: Install adequate AC and DC surge protection based on your area's requirements. Without proper protection, an inverter failure caused by surge damage may not be covered under warranty.
5. Preparing for Installation: Ensure that the installer understands how to install and commission the system before going to the site. Familiarize yourself with the documentation provided by KODAK and consult additional guides on the Segen portal for specific configurations.
6. Warranty: In the rare event of a failure, proof of correct installation is required for warranty claims. Take photos of the installation, including the installed protection, as evidence.
7. Commissioning: Never make connections with live cables, as it can cause arcing and void the warranty. Before turning on the grid or PV, set up the correct battery settings and ensure BMS communication is working.
To simplify the design process and ensure accuracy, you can use Kitbuilder, which automatically considers all the above-mentioned points.
