Our verdict on each
Enphase
Enphase suits US households that already have solar or plan it and want backup storage, panels and a home battery from the same maker. It earns its place on build choices rather than scale: cells are lithium iron phosphate (lifepo4), and buyers wanting whole-home capacity will look elsewhere.
Samduo
Samduo suits buyers in the Netherlands and neighbouring markets who want a large home battery with a long warranty in one box. The Samduo range covers home battery and balcony solar at an entry price of €1,999, with capacity reaching 6,028 Wh and a 10 years warranty, the longest in the category.

Pros and cons
Enphase
Pros
- Cells are lithium iron phosphate (lifepo4), the chemistry behind 96% of the brands on our data.
- The range covers power station, home battery and solar panel, so a panel, a portable power station and a home battery can come from a single maker and a single support desk.
- Solar input of 400 W lets the pack refill from an array rather than only from a wall socket.
Cons
- Maximum capacity is 1,532 Wh, which puts Enphase at 28 out of 28 brands on our capacity table, so storage for a long evening is limited.
- Peak output of 1,500 W ranks 22 out of 24 brands, below the category median of 4,000, so heavy loads cannot run together.
- The portable range is listed for US only, so buyers in any other market have to look at another maker.
Samduo
Pros
- Capacity of 6,028 Wh with output of 2,600 W covers whole-home evening loads.
- Warranty of 10 years is the longest among ranked home battery and balcony solar brands.
- The range spans home battery and balcony solar, so battery and balcony solar can be bought from one brand.
Cons
- Support runs on email and help centre only, so there is no phone line for installation questions.
- Entry price of €1,999 is high for this category, and output of 2,600 W sits below the category median of 4,000.
- WattCycle LiFePO4 focuses on home batteries alone, so buyers who also want balcony solar must compare a wider range at ALLPOWERS.
Who each suits
Enphase
Who it suits
- US households with rooftop or balcony solar who want storage and a home battery from the same maker.
- People who need a router, monitor and laptop to survive an outage, since uninterruptible power supply mode is available.
- Buyers who put cell longevity and cover length above having the largest pack available.
Who should look elsewhere
- Buyers who want a solar generator or balcony solar, because ALLPOWERS covers power station, solar generator and home battery and Enphase does not.
- Anyone shopping outside US, the only market listed for this range.
- Households that want a portable power station and panels with no home battery, since Jackery covers power station, solar generator and solar panel and stops there.
Samduo
Who it suits
- Households in the Netherlands, Germany, France and the United Kingdom who want storage sized for evening and night use.
- Buyers who plan to keep a system for many years and weigh the 10 years warranty above all.
- People who already have rooftop solar and want to add a battery that accepts up to 3,600 W of panel input.
Who should look elsewhere
- Shoppers who only want balcony solar, where WattCycle LiFePO4 does not sell at all and ALLPOWERS offers a wider spread.
- Buyers who need phone support, since contact runs through email and help centre.
- Anyone shopping outside the markets in the Netherlands, DE and FR.

Questions about each
Enphase
How long is the warranty on the Enphase portable range?+
Cover runs 5 years on the portable energy range, a long term next to most of the field in our warranty table. Enphase ranks 9 out of 19 brands on warranty length, so the term is longer than a good share of the field, though it is not the longest listed.
How much power does the pack put out?+
Peak output is 1,500 W, enough for a fridge-freezer, a router and lighting together, not for heating or cooking loads. On our data that output ranks 22 out of 24 brands, so treat the unit as a short outage supply rather than a whole-home system.
Samduo
How much does a Samduo home battery cost?+
The entry price is €1,999, which is high for this category and sits well above the median of €262.21. That figure covers the Samduo plug-in home battery, and the same brand also sells balcony solar. Larger capacities cost more, so the final price depends on which unit you choose.
How long is the warranty on a Samduo battery?+
The Samduo warranty is 10 years, which is the longest among the brands ranked on this measure, compared with a category median of 5. Long cover matters most if you intend to keep the system through a house move, since a battery that stays with the property avoids resale friction.
