Solax BMS-PARALLEL-BOX-II Energy Storage Expansion Module (IP55)

The Solax BMS-PARALLEL-BOX-II expansion module allows you to increase the supported number of T-BAT H 5.8 batteries in energy storage systems. Using this device eliminates the need to connect an additional master battery with an integrated BMS.

The Solax BMS-PARALLEL-BOX-II is a device designed to expand energy storage systems based on X1-Hybrid and X3-Hybrid series inverters. Using this module allows you to increase the number of supported T-BAT H 5.8 batteries from 4 to 8 units for three-phase inverters, and from 3 to 6 units for single-phase models. The alternating operation of dual modules also prevents inverter downtime in the event of an error in one of the circuits.

Key features

• System expansion for X3-Hybrid inverters up to 8 T-BAT H 5.8 batteries
• System expansion for X1-Hybrid inverters up to 6 T-BAT H 5.8 batteries
• No need for an additional master battery with a BMS
• Communication with the inverter via CAN2.0 and RS485 protocols
• IP55 protection rating
