❓ Frequently Asked Questions
🔹 Does the module support parallel expansion? Max number?
Yes, hardware natively supports up to 16 modules in parallel with current sharing. Hot-swap is supported for online maintenance.
🔹 Which communication protocols are supported? Can it interface with third-party BMS?
Standard CAN + RS485 with Modbus and dedicated energy-storage protocols. Directly connects to BMS, EMS, and host computers.
🔹 Is power derated at high / low temperatures?
Operating range -30°C to +65°C. Automatic linear derating above 55°C; no power limitation at low temperatures.
🔹 What are the key advantages over non-isolated bidirectional DC/DC?
Built-in high-frequency isolation transformer eliminates line-frequency transformer – smaller size, lighter weight, lower system cost. Full HV/LV isolation with 97% efficiency.
🔹 Is custom voltage / power rating available?
Yes. Imax Power offers full customization for voltage ranges, bus voltage, power, communication protocols, and thermal design.
