Revolutionizing C&I Solar Power Integration – Growatt’s WIT+APX Energy Storage System – EQ
India’s solar market is led by commercial and industrial (C&I) applications, accounting for a significant 70-80% of all the rooftop solar installations, according to the report. It’s because, in India, residential and agricultural users are subsidized while C&I consumers are levied an additional significant cross-subsidy surcharge leading to higher than average mains electricity tariffs. Electricity costs are up to 50% of their total expenses. Thus, cutting such costs via solar power sustainably improves their competitiveness in a big way. This shift towards solar energy in the C&I sectors also supports India’s renewable energy goals and enhance sustainability.
Why we need energy storage?
It is likely that in the next 2-4 years, 20% of all C&I installations will be connected to the grid, coupled with battery storage. Energy storage helps further optimize solar energy utilization and combat escalating energy prices in C&I sector. Moreover, the volatility and intermittency of solar power and other unpredictable factors all emphasize the importance of energy storage solutions (ESS). Businesses stand to gain energy independence and achieve clean energy objectives through the adoption of ESS. Growatt has introduced WIT 50-100K HU/AU with APX Commercial Battery system for C&I energy storage projects.
Major Applications
The ‘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. This system caters to diverse customer needs, ultimately ensuring their optimal benefits.
Key Features
The 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 high-watt power module. This product is 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.
In terms of 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 Growatt’s innovative ‘WIT+APX’ C&I energy storage system. Committed to creating the world’s largest intelligent sustainable ecosystem, Growatt continues to pioneer innovation, offering cutting-edge products to support the transition to clean and eco-friendly energy.
