Single Phase Solution

SOFAR HYD 3000-6000 EP – 3-6kw

If you have a single phase grid connection, let us introduce the HYD 3000-6000-EP, the latest multi-talented hybrid inverter designed for solar and storage applications. This cutting-edge inverter ensures reliable performance during grid-outages by providing up to 5 kW of emergency power supply (EPS) within a rapid response time of <10 ms through its integrated EPS-port.

The integrated energy management system offers a range of user-friendly modes, optimizing the overall user experience. These modes include an automatic self-use mode, allowing for seamless operation. Users also have the flexibility to set different time and date ranges or day of the week rules to meet their specific requirements. All modes can be easily configured using the large LCD screen, ensuring convenience and ease of use.

The inverter comes in 7 different sizes, 3.0, 3.68, 4.0, 4.6, 5.0, 5.5, and 6.0 kW, all come with a 10 year product warranty and weigh 21.5 kg. All batteries come with a 10 year product  and performance warranty and weigh 47 kg each. 

Among its many features, the HYD 3000-6000-EP is compatible with SOFARSOLAR’s LV battery series, GTX 5000, enabling seamless integration and expanded storage options. You can add up to 4 batteries in parallel, with a depth of discharge of 90%. The battery is a lithium iron phosphate battery, meaning the cathode material is lithium iron phosphate, and the anode is a graphitic carbon electrode with a metallic backing. This means they have a lower cost, highly safe, toxicity is low (no cobalt) and a long life cycle. These type of batteries are used extensively within the EV market.

To facilitate seamless connectivity, a WiFi-stick is provided with the inverter, allowing for easy connection to the SOFAR View monitoring portal for efficient monitoring and control.
