The new battery solution incorporates the technology of soft-switching parallel connection, which allows each module to fully charge and discharge on its own, thereby increasing the amount of energy that can be stored. This is accomplished by eliminating the effect of the energy mismatch that can occur between packs. Additionally, the APX offers installation and expansion flexibility with batteries that come from a variety of batches and have varying states of charge (SoC). Additionally, it has a redundancy architecture that prevents the system from shutting down due to a faulty pack.
According to Lisa Zhang, Growatt’s vice president of marketing, “to assure the utmost safety of the APX HV battery system, we use five layers of comprehensive protection in the product.” [Citation needed] “Protection measures include an active Battery Management System (BMS) for each cell, an arc-fault circuit interrupter (AFCI), and a replacement fuse for the entire system,”
The APX HV battery has a protection grade of IP66 and sophisticated self-heating technology, which together make it possible for the battery to function in temperatures as low as -10 degrees Celsius outside. Installing the solution is made easier by the fact that it is plug-and-play. In addition to this, the pre-charging procedure is rendered unnecessary, which cuts down on the amount of work and time required for parallel connection and maintenance. The APX HV system is able to dynamically identify newly inserted battery packs and will immediately upgrade the software to the most recent version for the previously used batteries.
“With a maximum parallel expansion of 60 kWh of electricity by two clusters, the one-size-fits-all battery is compatible with our single-phase, split-phase, and three-phase battery-ready inverters,” said Zhang.
