BLUETTI, a company making a name for itself in the energy storage system (ESS) and inverter segment, showcased its latest offerings aimed at providing full home backup and off-grid power supply to US consumers at RE+ 2025.
Hybrid Inverter for Household
The company displayed its hybrid inverter, EnergyPro 13K, designed for large homes at the show. The company states that the product has been developed to provide services beyond backup power supply. Rated for a full-load output of up to 13.2 kW, this inverter can be paired with a PV array of up to 22 kW capacity, and it supports up to 1.66 times DC/AC oversizing. As PV modules rarely operate at their nominal capacity due to shading, current mismatch, and overcast weather, this attribute ensures the inverter operates close to its full capacity most of the day. Regarding the backup power, combining with a vertically stacked external battery bank of up to 19.2 kWh of storage capacity, it supports backup of up to 13.2 kW for 1.45 hours at a nominal discharge rate. However, BLUETTI didn’t share the nominal charge or discharge rate of the inverter. This storage system can also be upscaled by connecting 3 units in parallel to feed a maximum power of 39.6 kW and provide backup power of up to 57.6 kWh.
The exhibitor presented another hybrid inverter, the EnergyPro 6K, focused on small households. Compared to the above, it integrates an inverter and storage in a single platform, which the company calls an ‘all-in-one’ design. It can provide a maximum AC power output of 5.76 kW while pairing with up to 7.68 kWh of storage capacity. Additionally, its capacity can be expanded by connecting up to 5 units in parallel.
During extended grid outages, both products can optimize energy distribution to feed the connected loads efficiently. For an extended backup beyond the capacity of the battery bank, these inverters can be integrated with the owner’s electric vehicle (EV) or diesel generator (DG) via a smart panel. Additionally, the company states that the microgrid-forming capability of these offerings enables energy independence.
Backup for Fridges
Also on display was the company’s hybrid solution – FridgePower. As the name implies, this product was developed for household fridges. Housed in a 75 mm thin casing for flat, vertical, or wall-mounted installation, it offers a rated 1-phase power of up to 1.8 kW and a storage capacity of 2.016 kWh, which can be expanded to up to 8.064 kWh. During grid outage or faults, the system switches to uninterrupted power supply (UPS) mode in less than 10 ms to ensure essential loads do not go offline.
Off-Grid Solutions
The company promoted its RVSolar System for applications such as recreational vehicle (RV), boats, and remote cabins, which need uninterrupted power supply in off-grid mode. According to the company, it supports vehicle integrated loads (AC and DC) of up to 6 kW of capacity; however, the storage capacity can be expanded to a maximum of 122 kWh.
The company also showcased its standalone off-grid solution, Apex 300, to offer backup power for critical loads. This solution can deliver AC power of up to 3.84 kW in combination with 2.764 kWh of storage capacity, while these capacities are expandable to up to 11.52 kW and 58 kWh, respectively.
The commercialization details of all the displayed products are not publicly available as of the time of publishing this article.
