Choosing a Home Battery: The Complete Buying Guide 2026

Step 1: Determine why you want a home battery

Your reason for purchasing determines which type of battery is the best fit. The three most common reasons:

Maximise savings on your energy bill

You have solar panels and want to feed back as little electricity to the grid as possible. Especially relevant now that the net metering scheme ends in 2027. You are looking for a battery with enough capacity to store your daily surplus.

Important: Choose at least 5 kWh, preferably 10 kWh. Focus on charging efficiency and the number of cycles.

Independence and backup power

You want to be less dependent on the grid and keep your most important appliances running during a power cut. Pay attention to whether the battery has a UPS function or backup function.

Important: Not all batteries offer backup power. Check whether the system has an automatic switchover and how much power (Watt) it can deliver during an outage.

Earn money with dynamic tariffs

You have a dynamic energy contract and want to smartly charge the battery when electricity is cheap and discharge when the price is high. This requires a battery with smart control and a connection to your energy supplier.

Important: Choose a system that supports IFTTT, Home Assistant or its own smart charging strategy.

Step 2: Calculate the right capacity

The capacity of a home battery is expressed in kilowatt-hours (kWh). Rules of thumb:

Tip: An oversized battery is not cost-effective — you won't fill it daily. An undersized battery leaves money on the table. The sweet spot for most households is 10 kWh.

Step 3: Plug & play or hardwired?

There are two main types of home batteries:

Plug & play (socket battery)

• Connects to a regular power socket
• No installer required
• Maximum 800W continuous (EU standard) or 2,000W with upgrade
• Ideal for tenants or those who want to get started quickly
• Examples: Anker SOLIX Solarbank, Zendure SolarFlow, ZinVolt Base

Hardwired (fixed installation)

• Connected to your consumer unit by a certified installer
• Higher power output possible (3,000-10,000W)
• Full backup power capability
• Higher capacities available
• Examples: Huawei LUNA 2000, Anker SOLIX X1, EcoFlow DELTA Pro Ultra, SolarEdge Home Battery

Comparison

Step 4: What should you look for when comparing?

Capacity (kWh)

How much energy the battery can store. Note: the usable capacity is sometimes lower than the nominal capacity. A 10 kWh battery with 90% DoD (Depth of Discharge) effectively delivers 9 kWh.

Power (kW)

How fast the battery can charge and discharge. A battery with 3.5 kW power can deliver a maximum of 3,500 Watt at once. Important if you have a heat pump or induction hob.

Cycles and lifespan

A cycle is one complete charge and discharge. Most home batteries offer 6,000-10,000 cycles. With daily use, that is 16-27 years. Choose a minimum of 6,000 cycles.

Battery technology

• LFP (Lithium Iron Phosphate): Safer, longer lifespan (6,000+ cycles), slightly lower energy density. The standard for home batteries in 2026.
• NMC (Nickel Manganese Cobalt): Higher energy density, but shorter lifespan and higher fire risk. Less commonly used for home storage.

Advice: Always choose LFP for home storage. All major brands have switched to LFP technology.

Warranty

Look at both the duration (years) and the capacity guarantee (e.g. 70% remaining capacity after 10 years). Market standard:

• Anker SOLIX: 10 years
• EcoFlow: 5 years (extendable)
• Huawei: 10 years
• Zendure: 10 years

Smart features

• Connection with smart meter (P1 port)
• App control
• Dynamic tariff optimisation
• Home Assistant / IFTTT integration
• Charge/discharge schedules

Frequently asked questions

What is the best home battery of 2026?

There is no universally "best" home battery. The best choice depends on your situation. For most households with solar panels and average consumption, a 10 kWh LFP battery with smart control offers the best balance between price and performance.

How much does a home battery cost in 2026?

Prices range from €999 for a compact plug & play unit to €8,000-12,000 for a large hardwired system. On average, you pay €300-500 per kWh of storage capacity. Prices have dropped 15-20% in 2025-2026 compared to 2024.

Do I need an installer?

Not for plug & play systems — you connect them yourself to a power socket. For hardwired systems, you need a certified installer who connects the battery to your consumer unit. Budget €300-800 for installation costs.

Can I expand later?

Most modern home batteries are modular and expandable. Do check in advance whether the brand offers expansion modules and what the maximum system capacity is. Anker SOLIX X1 is expandable to 180 kWh, ZinVolt Base to 24 kWh.

Can I reclaim VAT on a home battery?

Yes, if you connect the home battery to a solar panel system, you can reclaim the 21% VAT from the tax authority as a private individual. This applies to both plug & play and hardwired systems.
