EcoFlow STREAM Microinverter A compact, plug-and-play device built to efficiently convert solar power into usable home electricity—designed for seamless integration into your energy system. Product Highlights IP67 water-resistant for reliable outdoor performance Delivers consistent solar power conversion—even under low sunlight Compatible with 99% of solar panel brands Plug-and-play installation makes setup fast and simple Save Up to £115 Annually (estimated) The STREAM Microinverter works with your solar panels to produce up to 858 kWh per year. That's enough to power everyday essentials like your Wi-Fi router, fridge, and TV—saving you up to as much £115 a year on electricity bills. Actual savings will vary. Reliable Power—Even in Dim Conditions Whether it's early morning or overcast skies, the microinverter activates with just 3W of input—ensuring your home stays powered from dawn to dusk. Smarter Energy Control with Eco-AI Connect to the EcoFlow App to automate your power usage with Eco-AI. The intelligent TOU (Time-of-Use) mode helps you reduce costs by analysing your grid and solar data, while the EcoFlow Assistant gives you full control of your energy use remotely. Note: in the UK, wiring regulations require that the STREAM microinverter should be connected to your home wiring only via a fused spur using a DIY cable (select second option in this listing). The cable and relevant circuit in your fuseboard must be marked with a warning label indicating that the micro-inverter must be disconnected to de-energise the circuit. The installation must be performed by a licensed electrician. Contact us for advice.

It is designed to convert solar power from compatible PV panels into usable AC electricity for the home, with surplus generation exported to the grid where permitted. UK plug-in solar regulations are changing. New regulations come into force on 27 August 2026 and are intended to permit compliant plug-in solar microgenerators to connect through a standard UK plug and socket. However, this route only applies where the complete product complies with the UK Government’s Plug-in Solar Device Interim Product Specification, including the required plug, cable, labelling, documentation, safety protections and G98/grid-registration requirements. Until the new rules are in force, and unless the product is confirmed as compliant with the UK plug-in solar specification, the STREAM Microinverter should be connected to the property’s electrical installation only by a suitably qualified electrician, normally through a fused connection unit or other compliant dedicated connection, in accordance with BS 7671, applicable DNO/grid-connection requirements, Engineering Recommendation G98 and EcoFlow’s installation instructions. The installer must assess the existing circuit before connection, including the condition and rating of the wiring, earthing, RCD/RCBO protection, labelling, isolation, cable routing and suitability of the socket or connection point. The connected circuit and any relevant protective devices should be clearly labelled to warn that the microinverter must be disconnected to de-energise the circuit. The STREAM Microinverter is IP67 rated, but outdoor installation must still take account of mounting security, ventilation, shading, cable routing, mechanical protection, weather exposure, corrosion risk and safe access for maintenance. Solar panels and mounting systems must be installed securely and in accordance with the manufacturer’s instructions, taking account of wind load, fixing method and the condition of the supporting structure. This product is a solar microinverter and does not itself provide battery storage. Plug-in batteries and plug-in solar-plus-battery systems are not covered by the new UK plug-in solar route and require separate assessment. This summary is for general product information only and does not constitute legal, electrical or professional advice. Customers should always consult a qualified electrician or competent designer before installation.

A moderate temperature increase during operation is normal and does not affect product lifespan. STREAM Microinverter includes a multi-stage thermal management system. For best results, install in a shaded, ventilated space away from pets or children. How do I monitor the electricity generated by the STREAM Microinverter in real time? Use the EcoFlow app to track real-time solar generation, energy output, and consumption when your STREAM Microinverter is connected. Can I use third-party solar panels? Yes. As long as the panels use MC4 connectors and stay within the input spec range (16–60V, ≤16A), third-party panels are supported. How should I connect multiple solar panels to my STREAM Microinverter? Match each PV group to the input limits: Max 60V and 16A. Ensure all connected panels share the same specs. EcoFlow offers extension/parallel cables if needed. Ideal group wattage: 200W–600W. Can EcoFlow’s Portable Power Stations be used with the STREAM Microinverter? No. This microinverter is designed exclusively for the STREAM series and is not compatible with EcoFlow’s portable stations. Will excess power be fed into the grid? Yes, excess energy generated during the day is automatically fed into the grid if not used by your household. Does the STREAM Microinverter require separate grounding? No extra grounding is needed if plugged into a properly grounded outlet. For local compliance or unclear socket grounding, consult a licensed electrician or EcoFlow support. Can the STREAM Microinverter connect to 5G Wi-Fi? It currently only supports 2.4GHz Wi-Fi. Can I adjust the maximum output power? Yes, via the EcoFlow app. Navigate to: Space > Settings > Maximum Output Power. document.addEventListener("DOMContentLoaded", function () { const toggles = document.querySelectorAll(".faq-toggle"); toggles.forEach(toggle => { toggle.addEventListener("click", () => { toggle.classList.toggle("active"); }); }); });
