Growatt’s WIT+APX Energy Storage System Aims For Emerging Storage market

Growatt’s ‘WIT+APX’ C&I energy storage system, designed for commercial, industrial, and micro-grid scenarios, offers eight distinct application modes: self-consumption, peak shaving, demand charge, power expansion, micro-grid, backup power, and power quality. The flexibility to meet the requirements of diverse customer needs is a function of not just the product design, but the firm’s belief that storage demand  is set to soar in the near future across segments.

Key Features

The Growatt’s WIT 50-100K-HU/AU storage inverter offers a maximum efficiency of 98.2% with up to 10 MPPTs and 20 strings. With a DC/AC ratio up to 2.0 and a string current of 16A, it is compatible with most high-watt power modules hitting the market today. Engineered to manage a 100% unbalanced load in backup mode, ensuring exceptional reliability, for off-grid use, it supports parallel operation of up to 3 units, reaching a total of 300kW. Additionally, for on-grid use, it supports parallel operation of up to 9 units, providing a total capacity of 900kW. This versatility makes it well-suited to address diverse power demands.

When it comes to safety, it boasts a fuse-free design, ensuring maximum uptime and reducing maintenance requirements. It also features a built-in PID recovery function, IP66 protection level, Type II SPD on both DC and AC sides and active ARC protection (AFCI). The APX Commercial LFP batteries feature a redundant design and multi-level protection for robust safety. With an operational range of -10°C to 50°C, IP66 protection, and scalability up to 200kWh, they’re suitable for outdoor installations. The control/power module enables energy optimization, supporting full charge/discharge and the mixing of new and old battery packs or batteries of different SOC.

Businesses can achieve energy independence with the ‘WIT+APX’ C&I energy storage system, promises Growatt. In the Indian market, that promise is set to be tested sooner than later by many establishments as they seek to benefit from relaxed green power access rules.
