Growatt promoted its latest NEXA 2000 all-in-one balcony solar storage system, targeting the residential market
This 800 W system can be integrated with a battery bank rated at 2.048 kWh
The company also showcased its latest C&I scale 3-phase hybrid and string inverters
Addressing the growing demand for residential and C&I scale PV + storage applications in China, Growatt showcased its broad product portfolio at the recently held SNEC 2025.
During the event, the company displayed its newly launched NEXA 2000 all-in-one balcony solar storage system, along with other products, targeting residential applications. Regarding the C&I-scale application scenario, it promoted the WIT 30–100K-HU and MAX 100–150KTL3-X2 LV series hybrid and string inverters.
The NEXA 2000 all-in-one balcony solar storage system, equipped with 4 MPPT channels connected to a single PV string, can accommodate a PV input capacity of up to 2,600 W with a maximum input current of 20 A. In addition to PV integration, the system can be paired with a battery bank rated at 2,048 Wh, expandable up to 8,192 Wh by parallel connection of up to 4 units. In on-grid mode, it can deliver a 1-phase output power and current of up to 800 W and 3.5A, respectively.
Thanks to its compatibility with intelligent energy monitoring solutions such as Shelly meters, Shunt meters, and the everHome Ecotracker P1 (used with smart meters from grid operators), the system can monitor real-time household electricity consumption and dynamically store surplus PV energy. This stored energy can then be used when needed, thereby maximizing solar self-consumption and reducing reliance on the grid. In the event of a grid outage, the system’s off-grid mode can deliver up to 800 W of AC power and an output current of 3.5 A at 230 V, for a duration determined by the battery bank's capacity.
Its compact dimension of 406 × 255 × 290 mm and vertically stackable battery design make it ideal for residential balcony installations in limited spaces. Growatt offers a 10-year warranty for this product.
Complementing its residential storage solutions, Growatt introduced its C&I scale WIT 30–100K-HU 3-phase hybrid inverter at the show. This inverter is engineered to integrate up to 200% DC/AC oversizing capability. With the flexibility of switching between on-grid, off-grid, or diesel generator (DG) modes, it can offer multiple operational functionalities like peak shaving, load shifting, and emergency backup, stated the company.
Addressing the need for larger C&I systems, Growatt promoted its MAX 100–150KTL3-X2 LV series 3-phase string inverter. Designed to incorporate up to 150% DC/AC PV oversizing capacity, its 10 MPPT channels, with a wide range of voltage between 180 V and 1,000 V, can carry up to 22.5 A string current. According to the datasheet, it can deliver up to 150 kW 3-phase AC output power.
Mitigating potential hazards related to safety and protection in C&I scale scenarios, this new model is empowered with multiple safety features, including type II SPD, fuse-free design, PID recovery, and arc fault detection.
