Accessories & BMS
The parts that decide whether a system reports honestly and whether its battery reaches the cycle life on the datasheet.
Remote monitoring turns a UPS into a managed asset; the BMS and the charger decide whether the battery reaches the cycle life on its datasheet. Both are sold here as components for integrators and as factory-fitted options on pack and system orders.
- SNMP cloud monitoring cards add SNMP, Modbus and cloud connectivity to compatible UPS and inverter models, with real-time email and SMS alerts for multi-site or unmanned installations.
- Smart BMS boards from 4S to 16S, 100 A to 300 A, with passive or active balancing and CAN/RS485/Bluetooth communication. We load the inverter protocol at the factory.
- LiFePO4 chargers from 12 V to 72 V with a correct absorption and float profile — a charger that is merely "compatible" with lithium is how packs die early.

Models with links have detailed specification pages; unlisted models are also available on request. Capacity and quantity should be sized by our engineers against the actual load — never by nameplate rating alone.
