Our verdict on each
Deye
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.
Fossibot
Fossibot suits buyers who want a large portable station with high output and a stated cycle life, and who can live with a short warranty. Its largest unit pairs 5,222.4 Wh of capacity with 7,200 W of output, so it ranks well on power against the peers listed here.

Median across 33 listed brands.
Pros and cons
Deye
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.
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.
Fossibot
Pros
- Output of 7,200 W is the highest figure listed for the brand.
- Capacity of 5,222.4 Wh paired with 7,200 W of output gives real headroom for high-draw kit.
- Ups mode is offered, which matters for carrying electronics through a power cut.
Cons
- The warranty runs 2 years, below the 5 typical in the portable power stations group.
- Support runs on email and help centre, so a phone line is not part of the service.
- A home battery is not among power station, solar generator and solar panel, while power station and home battery and power station, solar generator and home battery both list one.
Who each suits
Deye
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.
Fossibot
Who it suits
- Households wanting one large portable station with high output for outages or worksites.
- Buyers already holding solar panels who want strong charging input on their unit.
- Shoppers in the markets Fossibot sells into who weight output above cover length.
Who should look elsewhere
- Buyers after fixed home storage, since a home battery is not among power station, solar generator and solar panel while power station, solar generator and home battery and power station and home battery both list one.
- Anyone who needs phone support, since support runs on email and help centre.
- Shoppers planning a long working life, since 2 years sits below the 5 in this group.

Questions about each
Deye
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.
Fossibot
How much does a Fossibot power station cost to buy?+
Prices start at $399 across the portable power station collection. That figure sits mid-table in our data at 16 of 27, so it is neither the cheapest entry point nor the most expensive one. Larger units cost more, and the largest unit in the range is the one carrying 5,222.4 Wh of capacity.
What is the biggest output a Fossibot station can deliver?+
The largest unit delivers 7,200 W, the highest output listed for Fossibot. That places the brand at 6 of 24 on output, ahead of its placings on the other measures in this comparison. A station like that can run high-draw equipment that smaller units in the same category cannot.
