DALY BMS Releases Guide for Solar Storage Battery Management System Compatibility

DALY BMS, a manufacturer of battery management systems (BMS), has released its latest guide aimed at solar storage system original equipment manufacturers (OEMs) and integrators. The publication provides technical insights into the compatibility of BMS solutions with hybrid inverters, with a particular focus on the Pylontech CAN protocol, which has become an industry de facto standard.

The release emphasizes that a simple "lithium-compatible" label on an inverter's datasheet does not guarantee communication with the battery's BMS. The real challenge lies in whether the BMS implements the Pylontech CAN protocol and if the same product can scale for various system sizes without software modifications. DALY BMS's guide delves into inverter ecosystems, six critical specifications, certification pathways, and common procurement mistakes.

A primary challenge identified is the diversity of inverter brands. Solar storage systems must interface with inverters from multiple manufacturers, each maintaining its own approved battery list. DALY BMS solutions support a wide array of brands such as Deye, SMA, Sol-Ark, and Huawei, and are designed for scalability from 5 kWh single packs up to 80 kWh commercial systems within a single product family.

The guide also introduces DALY BMS's fourth-generation BMS, featuring built-in Pylontech compatibility and supporting parallel connection of up to 16 batteries. It covers essential technical specifications including voltage levels, continuous current, parallel architecture, and balancing capabilities. The company offers a complimentary compatibility consultation with its engineers based on the target inverter brand and model.
