When there is no power supply to connect to the EcoFlow 400W Solar Panel is the perfect solution to recharging your portable power station. The EcoFlow solar panel is constructed with monocrystalline silicon cells which are highly efficient and reliable. The solar panel has been designed to work with the EcoFlow Delta, Delta Max & Delta Pro range of portable battery generators.

Lightweight and Versatility of the EcoFlow 400W Solar Panel

The EcoFlow 400W solar panel is an efficient, foldable solar panel and comes in a stylish and convenient carry case. Weighing in at just 12.5kg the EcoFlow solar panel can be transported easily with the aid of a shoulder strap. Up to 4 solar panels can be connected in series to generate extra charging capacity (EcoFlow Delta Pro only). This combination will be capable of charging an EcoFlow Delta Pro in 2.8 to 5.6 hours hours. With the MC4 output this EcoFlow solar panel can connect to any other EcoFlow portable power station and other portal battery generators.

Is the EcoFlow 400W Solar Panel Waterproof and Durable?  

The solar panel is made from layers of pliable EVA and durable fiberglass, this combination makes the panel flexible and strong. So strong it reviles the strength of most rigid solar panels. Each monocrystalline silicon cell is covered with ETFE film, protecting against debris, dirt, and water. With an IP67 waterproof rating, the portable solar panel works in all kinds of weather, perfect for both camping and rooftop use.

Self-supporting 400W Solar Panel

The protective case of the EcoFlow 400W solar panel conveniently turns into a handy stand that can adjust from 40-90° allowing the solar panel to capture the best possible sunlight.

Smart Solar Energy

The EcoFlow 400W solar panel has a conversion efficiency of 22.4%, and when paired with an EcoFlow portable solar generator, can extract the maximum power throughout the day. The solar generator adjusts its efficiency using the Maximum Power Point Tracking (MPPT) algorithm, to deliver a constant power supply.

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.
