Harness Solar Power Efficiently with the EcoFlow PowerStream Microinverter

The EcoFlow PowerStream Microinverter is engineered to deliver unparalleled performance and efficiency, ensuring you make the most of your solar energy system. Unlike traditional inverters, which are prone to performance degradation due to shading or individual panel malfunctions, the PowerStream Microinverter optimises the output of each solar panel independently.

By converting the DC power generated by each panel into AC power right at the source, the PowerStream Microinverter minimises power losses, increases energy production, and maximises the overall efficiency of your solar installation. The EcoFlow PowerStream Solar System is a balcony solar system with the addition of a portable power station (sold separately) will allow you to use solar energy day and night and reduce energy bills.

Advanced Features for Optimal Energy Harvesting

The EcoFlow PowerStream Microinverter is equipped with advanced features that make it an ideal choice for small residential solar installations. Its Maximum Power Point Tracking (MPPT) technology ensures that the microinverter operates at the optimum voltage and current levels, even in changing weather conditions. This feature guarantees that you get the most power out of your solar panels, maximising energy production throughout the day.

Additionally, the EcoFlow PowerStream Microinverter boasts a high conversion efficiency, allowing it to convert a greater proportion of the sun’s energy into usable electricity (800W Max). This efficiency translates into higher energy yields and increased savings over time. This system stores all excess energy in a portable power station during the daytime and gives it back to you whenever you need it.

Works With all EcoFlow Portable Power Stations

The EcoFlow PowerStream Microinverter is compatible with all the current EcoFlow portable power stations: DELTA Pro, DELTA Max 2000/1600, DELTA 2 Max, DELTA 2, RIVER 2 Pro, RIVER 2 Max, RIVER 2.

Easy Installation

The EcoFlow PowerStream Microinverter is designed with simplicity and flexibility in mind. It offers a plug-and-play installation process that is hassle-free and should be completed by a professional installer only. The microinverter’s compact size and lightweight construction make it easy to handle and install, saving you time and effort during the setup.

UK regulations are slightly different to European regulations and do not allow back-feeding a micro-inverter via a three-pin plug. So, to use the micro-inverter in the UK it must be installed by a qualified electrician and permanently connected to your premises electrical circuit. We can supply a cable for this installation and you should not use the AC cable that is supplied with the inverter. See the guide in the documents section. (The EcoFlow PowerStream Microinverter has G99 UK grid connection approval – ENA Connect Direct (energynetworks.org))

Intelligent Monitoring and Remote Management

Monitoring and managing your solar energy system is made effortless with the EcoFlow PowerStream Microinverter. The integrated monitoring system provides real-time data on each panel’s performance, allowing you to track energy production, identify potential issues, and optimise your system’s efficiency. You can access this information through a user-friendly dedicated smartphone app, giving you control over your solar installation from anywhere at any time.

Furthermore, the EcoFlow PowerStream Microinverter offers remote firmware updates, ensuring that your system always has the latest features and performance enhancements. This feature saves you from the hassle of manual updates and ensures that your microinverter is always operating at its best.

Durability and Reliability

When it comes to investing in a solar energy system, durability and reliability are crucial factors to consider. The EcoFlow PowerStream Microinverter is built to withstand the harshest environmental conditions, thanks to its robust construction and IP67-rated enclosure. This level of protection ensures that the microinverter is dustproof and water-resistant, making it suitable for installation in various climates.

Delivery

When will I receive my order?

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
