Quick Answer
Yes, it is possible to mix different battery brands in a hybrid system, but compatibility and proper configuration are crucial to ensure optimal performance and safety.
Choosing Compatible Batteries
When selecting batteries for a hybrid system, it’s essential to ensure compatibility between the different brands and types. Typically, hybrid inverters will allow the use of multiple battery types, but some may have restrictions on the maximum number of strings or the minimum/maximum voltage and capacity requirements. For instance, the Fronius Primo series supports up to 3 different battery types, with individual settings for each.
Hybrid Inverter Configuration
To configure a hybrid system with mixed battery brands, you’ll need to set up the inverter according to the manufacturer’s guidelines. This may involve creating separate battery profiles or settings for each type, and configuring the inverter to communicate with each battery type accordingly. For example, the SMA Sunny Boy Storage 7.0 inverter allows users to create up to 8 different battery profiles, with adjustable settings for charge/discharge rates, voltage limits, and more.
Safety Considerations
When mixing battery brands in a hybrid system, safety should be the top priority. Make sure to follow the manufacturer’s guidelines for safe installation, operation, and maintenance. This includes ensuring proper grounding, using compatible wiring and connectors, and regularly inspecting the system for any signs of wear or damage. Additionally, it’s recommended to use a battery management system (BMS) to monitor and control the system’s performance, preventing potential issues like overcharging or over-discharging.
