EcoFlow has unveiled the single-phase Ocean 2 all-in-one battery inverter at Key Energy in Rimini. The system features a more compact 5 kWh LFP battery, stackable up to 30 kWh and offers a 100% depth of discharge, a discharge power of 3.4 kW and IP66 protection.
China-based storage system manufacturer Ecoflow has unveiled a new all-in-one battery inverter at the Key Energy trade show in Rimini, Italy.
“The Ecoflow Ocean 2 is the evolution of the previous Ecoflow Ocean system,” said Idilio Ciuffarella, the company’s Country Manager Italy. pv magazine. “It is a smart inverter coupled with an intelligent battery with an integrated BMS. Compared to the previous version, the battery is approximately 10 cm more compact and 10 kg lighter (approximately 50 kg), making it easier to install.”
“Compared to the previous version, the battery is approximately 10 cm more compact and 10 kg lighter, making it easier to install,” he continues. “Each battery has a capacity of 5 kWh and up to six units can be stacked for a total of 30 kWh in an all-in-one ‘mini tower’ configuration suitable for domestic use. The batteries are compatible with previous Power Ocean models and can be mixed within the same system.”
The new single-phase product offers improved specifications, including slightly higher discharge power (3.4 kW vs. 3.3 kW), 100% depth of discharge (from 95%) and IP66 protection (from IP65). It also features cloud-based management for remote updates and predictive maintenance. “The Ecoflow Ocean 2 inverter features an integrated backup with 0 ms switching time and arc flash protection. The product is being launched across Europe and was officially unveiled here in Rimini.”
The hybrid inverter is available in six variants, with a nominal AC output power from 3 kW to 6 kW and a maximum PV input power between 9 kW and 12 kW, depending on the model. The inverter has two MPPTs and supports a maximum of 18 A input current per MPPT. It operates over a PV voltage range of 90 V to 520 V, with a maximum input voltage of 600 V.
The system offers a maximum efficiency of more than 96%, with the European weighted efficiency exceeding 95%. It includes integrated backup functionality with a rated backup power of up to 6 kW, and supports 220 V/230 V/240 V operation at 50/60 Hz. Protection features include ground fault circuit interrupter (GFCI), arc fault circuit interrupter (AFCI), anti-islanding protection, AC and DC overvoltage protection, and insulation resistance detection.
The inverter has an IP65 protection rating and is designed for indoor and outdoor installation. It measures 679.6mm x 182.7mm x 280mm and weighs 21.5kg. Communication options include RS485, CAN, Wi-Fi, Bluetooth, WAN and 4G connectivity. The unit uses natural convection cooling and has a maximum operating altitude of 3,000 meters.
The storage component, called EcoFlow Ocean 2 LFP Battery 5 kWh, is based on LiFePO₄ cells and offers a nominal capacity of 5.02 kWh per module with a depth of discharge of 100%. The rated voltage is 400 V, with an operating voltage range of 360 V to 520 V.
Up to six battery modules can be stacked in a single tower, and up to four stacks can be connected in parallel. Floor-mounted configurations allow stacks of up to six batteries, while wall-mounted systems support up to three batteries per stack. Depending on the configuration, the total system capacity can exceed 30 kWh per stack.
The battery system is IP66 rated and operates in temperatures from -20 C to 55 C. It uses natural convection cooling and includes multiple protection mechanisms, such as overcharge and over-discharge protection, overcurrent protection, short circuit protection, thermal overflow protection, leakage current protection and emergency shutdown.
The all-in-one system is said to have a lifespan of 10,000 cycles and comes with a 15-year warranty.
