Our verdict

Deye suits buyers who want balcony solar and a home battery from the same maker, and its 10 year warranty outlasts the group median of 5 years. The trade-off sits at the output end, where 1,100 W of peak power keeps it aimed at small flats rather than whole-house loads.

Pros and cons

Pros

  • Warranty of 10 years, which places Deye at 1 of 19 brands and above the group median of 5 years.
  • Balcony solar and home battery from the same maker, where WattCycle LiFePO4 covers home battery on its own.
  • UPS mode on the balcony unit, so a small load can run through an outage instead of only storing daytime solar.
  • Capacity of 10,000 Wh with room for 2,200 W of solar input, a wider window than the 1,100 W its sockets deliver.
  • LFP chemistry, lifepo4, which 96% of the brands in this ranking also use.

Cons

  • Output of 1,100 W puts Deye at 24 of 24 brands, so it will not carry heavy loads.
  • Entry price of €600 is above the ranking median of €262.21 and ranks 19 of 27 brands on price.
  • Support runs on email and chat, and phone is the route 66.7% of the brands in this group keep open.
  • Shipping covers AT, BE and BG, so buyers outside that list rely on a local distributor.

Who it suits

  • Buyers who want balcony solar and a home battery from the same maker, rather than the portable power station route power station and home battery opens up at DATOUBOSS.
  • Households that plan around service life rather than peak power, given 10 years of cover against a group median of 5 years, with support handled on email and chat.
  • Buyers who want a balcony system under one long warranty and are not shopping for the panel-inclusive range power station, solar generator and home battery covers at ALLPOWERS.

Who should look elsewhere

  • Buyers who only want a home battery with no balcony kit, since WattCycle LiFePO4 lists home battery on its own and suits a pure storage brief.
  • Shoppers wanting a portable power station in the same basket, since DATOUBOSS lists power station and home battery and Deye's balcony solar and home battery leaves out a power station.

Where it sits among rivals

Deye's profile is uneven, and the ranking numbers show where. On storage size, Deye places 12 of 28 brands, which puts it well above the middle of a column that runs to much larger floor-standing cabinets. Peak output runs the other way, at 24 of 24 brands, effectively the bottom of that column, so anyone hoping to run a kettle and a washing machine together should look past this brand. Entry price sits at 19 of 27 brands, higher than most of the group, which is easier to swallow once the storage and warranty columns are read. Warranty length is the outlier in Deye's favour, at 1 of 19 brands. The pattern is a brand built for steady, long-lived storage rather than for sudden high loads.

What it does well

The balcony power plant with storage sits at the centre of the range, and its numbers are modest but coherent. Capacity tops out at 10,000 Wh, output at 1,100 W, and the solar input ceiling is 2,200 W, so a solid balcony array can push more power in than the unit hands back through its outlets. Chemistry is lifepo4, rated for 6,000 cycles, which suits a system expected to charge and discharge daily rather than serve as a rare backup. The unit also lists UPS mode, so it can carry a small load through an outage instead of only banking daytime solar. Against that, the warranty of 10 years is the most durable part of the package, and the number here that outruns most of the field.

Who runs it

The store belongs to Ningbo Deye Technology Co., Ltd., a manufacturer headquartered in China and founded in 2000, which places it among the longer established names behind the brands in this category. A named legal entity and a stated founding date mean the seller is a manufacturer rather than a marketplace reseller, and enquiries go to the brand's own desk. After the sale, support runs on email and chat. That pairing suits buyers who are comfortable with written replies and a live chat window, and suits less well anyone who wants to pick up a phone and talk an installer through a wiring question. For reassurance, the company details and the support channels are the concrete things a buyer can check before ordering.

Frequently asked questions

What does a Deye balcony system cost?+

Deye's energy storage range starts at €600. That figure covers the hardware, so the 10 year warranty is what sets the value horizon rather than any contract term. Against the field, the entry price ranks 19 of 27 brands and sits above the ranking median of €262.21, so expect to pay more than the typical starting figure here.

How much storage can a Deye system hold?+

The largest unit in the range holds 10,000 Wh of energy. That places Deye at 12 of 28 brands on storage size, comfortably above the group median of 7,994, though a long way short of the biggest cabinets at 94,500.

How much power can it output?+

Peak output is 1,100 W, and the solar input ceiling is 2,200 W, so panels can push more into the unit than its sockets can deliver. Output is where Deye sits lowest, at 24 of 24 brands against a group median of 4,000. It suits a small setup rather than a whole house on load.

How long does the battery last and what warranty comes with it?+

The warranty runs 10 years, which is the strongest point in the range and matches the top of the ranking at 1 of 19 brands. The cells are rated for 6,000 cycles, and the chemistry is lifepo4, the same choice 96% of the brands here make.

Which countries does Deye ship to?+

Delivery is listed for AT, BE and BG. That is a broad European footprint running from Ireland and Portugal through the Nordic and central European markets, with Australia and New Zealand at the far end of the list. Buyers outside those markets would need a local distributor rather than the store's own delivery.

Can it keep the lights on during an outage?+

Yes. The unit lists UPS mode, so it can keep a small load running through an outage rather than only banking daytime solar. 100% of brands in this ranking offer the same, so treat it as a baseline expectation here rather than a reason to pick Deye over WattCycle LiFePO4.

How do I reach Deye support?+

Support runs on email and chat. In this group 74.1% of brands answer by email while 25.9% offer chat, so Deye's pairing follows the category habit without adding a phone line for setup questions.

Does Deye sell balcony solar as well as home batteries?+

Deye covers balcony solar and home battery, so balcony solar and a home battery come from the same maker. That is narrower than ALLPOWERS, whose power station, solar generator and home battery run from power stations and solar generators through to panels. DATOUBOSS also lists power station and home battery, while WattCycle LiFePO4 stays on home battery alone.
