Growatt’s Latest Residential & C&I ESS At Intersolar

Well-known PV inverter and energy storage system (ESS) provider Growatt launched its 2 residential ESSs at Intersolar Europe 2026, while also displaying its commercial & industrial (C&I) ESS.  

The company’s latest MODA and MINA All-In-One ESS combines vertically stacked 5 kWh battery packs and a hybrid inverter in a single enclosure. Both products can relate to up to 6 vertically stacked 5 kWh battery packs, creating a storage capacity range of 5 to 30 kWh. However, their power output (AC) range and type differ. The MODA series can deliver 3-phase power output between 4 and 15 kW, while the MINA series has a rated single-phase power output range of 3 to 10 kW. 

On the PV generation front, they are designed for up to 200% DC/AC oversizing to maximize solar harvesting throughout the day. The 3-phase variant switches to off-grid mode within 20 ms of a grid outage and can support an emergency backup of up to 15 kW at 27.3 A for 2 hours. In contrast, its single-phase peer switches to off-grid mode within 10 ms and delivers up to 10 kW emergency backup at a full-load current of 45.5 A for up to 3 hours. It has a rated maximum conversion efficiency of 97.5%, while its 3-phase counterpart offers a higher value of up to 98.6%.  

For C&I applications, Growatt showcased its latest RISE 261H-XH series ESS, more than just an emergency backup source. It integrates multiple energy sources, including PV, grid, a diesel generator (DG), and battery storage, in an AC-coupled configuration via a built-in power conversion system (PCS). It is equipped with battery packs consisting of 314 Ah battery cells, for a cumulative storage capacity of 261 kWh. According to the company, this system can be fitted with a PCS of various capacities to meet the prosumer’s needs (50 kW, 63 kW, 85 kW, or 125 kW). Its capacity can be scaled up to 1.25 MW/ 2.61 MWh by connecting 10 ESSs in parallel. On the PV source side, its inverter is equipped with 10 MPPT channels and can support up to 200% higher DC capacity relative to rated AC power, maximizing solar generation. 

It can switch to emergency backup mode within 10 ms of a grid outage, activating the DG + ESS hybrid function. During this phase, the DG power supply is prioritized over storage, while the ESS comes into play only to discharge in real time, flatten load profiles, and maintain system stability once the C&I load overshoots. Meanwhile, the ESS can support a 3-phase unbalanced load of up to 100% (e.g., Phase A: 100 kW, Phase B: 0 kW, Phase C: 0 kW), further enhancing system stability. Additionally, it supports emergency overload of up to 160% for up to 10 seconds to ensure the continuous operation of high-inductive C&I loads.
