Growatt has released its new APX HV cobalt-free LiFePO4 battery to the global market.
Integrated with soft-switching parallel connection technology, the new battery solution stores more energy by eliminating the effect of the energy mismatch between packs, allowing each module to fully charge and discharge independently. The APX also provides flexibility for installation and expansion with batteries with varied state of charge (SoC) and from different batches. It also features a redundancy design that prevents system shutdown from a defective pack.
“To ensure the ultimate safety of the APX HV battery system, we apply five levels of comprehensive protection in the product,” said Lisa Zhang, VP of marketing at Growatt. “Protections include the active Battery Management System (BMS) for each cell, the pack-level energy optimizer and built-in fire protection of aerosols for each module, an arc-fault circuit interrupter (AFCI) and a replaceable fuse for the whole system.”
The APX HV battery applies an IP66 rating of protection and smart self-heating technology to enable operation outdoors and at the lowest temperature of -10℃. The plug-and-play solution allows for efficient installation. It also eliminates the pre-charging process, reducing efforts and time needed during parallel connection and maintenance. When new battery packs are added, the APX HV system dynamically recognizes and upgrades the software automatically to the latest version for the previous batteries.
“With a maximum parallel expansion to 60 kWh of electricity by two clusters, the one-fits-all battery is compatible with our single-phase, split-phase and three-phase battery-ready inverters, including MIN 2500-6000TL-XH, MIN 3000-11400TL-XH-US, MOD 3-10KTL3-XH for residential application, as well as our MID 12-30KTL3-XH inverters for commercial application,” said Zhang.
