šĀ 3. Anker SOLIX Solarbank 4 Pro: integrated solar storage
Anker SOLIX is another option for people researching home solar and battery storage.
TheĀ Solarbank 4 E5000 Pro is advertisedĀ with a 5,000Wh battery capacity, up to 5,000W solar input and 2,500W AC output.Ā ItsĀ official UK product page has advertisedĀ a price of Ā£2,129, with Ā£380 off the listed price.
For households considering a larger system, it is worth comparing the specifications, expansion options and total cost against other products in this guide.

Who might it suit?Ā Households looking forĀ an integrated solar-storage system with substantial capacity and expansion potential.
This is an advertised product offer, not necessarily a Halloween-specific promotion. Confirm the current price and terms before ordering.
āļø 4. Zendure SolarFlow: start with less and expand later
Zendure's SolarFlow range offers modular solar-storage options for people comparing different battery capacities.
One advertised option is the SolarFlow 2400 AC+, listed with 2.4kWh of battery capacity.
The UK listing has shown the following prices:
Product | Advertised price | Previous listed price |
Ā£899 | Ā£1,299 | |
Ā£1,798 | Ā£2,148 |
These offers are worth checking if you want to compare a smaller starting capacity with the possibility of adding storage later.
Why consider a modular system?Ā Not every household needs a large battery from day one. Starting with a smaller capacity may make more sense for your budget, especially if you're still learning how much electricity you can realistically store and use.
Before ordering, confirm which batteries are compatible with the exact model and whether additional equipment is required.

š 6. Shelly energy monitoring: understand your electricity use
You don't necessarily need to spend thousands of pounds on a battery to start making better energy decisions.
Energy monitoring can help you understand when your home uses electricity, which circuits consume the most and how your consumption changes throughout the day.
Shelly offers a range of energy-monitoring products, including the Shelly 3EM family. The right model depends on your electrical installation and whether you need single-phase or three-phase monitoring.
For households considering solar and storage, monitoring can help you understand your usage patterns before deciding which equipment to buy.
Who might it suit?Ā People interested in monitoring electricity use, assessing solar performance or making more informed decisions about battery storage.
Some devices require installation by a qualified electrician, so check the model's installation requirements before purchasing.
š” 7. Meross MSS315: a lower-cost smart energy gadget
If you're not ready to invest in a home battery, a smart plug with energy monitoring can be a more affordable place to start.
The Meross MSS315Ā is a smart plug designed to monitor the energy used by suitable connected appliances. A retailer listing has previously shown it at Ā£24.99, reduced from Ā£29.99, although this price needs checking before publication.
Smart plugs can help you identify how much electricity certain appliances consume and may let you control them remotely, depending on the model and setup.
Always check the plug's rated load and your appliance's requirements. Not every appliance is suitable for switching through a smart plug.
Who might it suit?Ā People who want to understand appliance consumption and explore smart-home energy management without committing to a large purchase.

āļø 8. Plug-in solar panels: could solar be your starting point?
With more households exploring plug-in solar, it is worth comparing suitable solar kits alongside battery systems.
Some households may benefit from generating electricity during daylight hours without immediately investing in a battery. Others may want storage so they can use more of their solar generation later.
The right choice depends on your property, electricity usage, available sunlight, budget and the equipment you can safely use.
Before buying a plug-in solar kit, check the latest UK rules, the kit's compliance, the microinverter's output limit, your electrical installation and the manufacturer's instructions. Requirements can differ by system and property.
Our tip:Ā Work out what you're trying to achieve before choosing the equipment. If your main aim is to use solar electricity during the day, a suitable solar kit may be a sensible starting point. If you want to store energy for later, compare the additional cost and benefits of battery storage.
š§ Which Halloween energy deal is right for you?
Here's a quick way to narrow down your options.
Your priority | Where to start |
Getting started with solar | Compare suitable plug-in solar kits |
Home battery storage | Compare EcoFlow, Anker SOLIX and Zendure |
Portable power for trips | Compare BLUETTI and Jackery |
Monitoring household electricity | Explore Shelly energy monitoring |
Monitoring individual appliances | Look at energy-monitoring smart plugs |
Our verdict: buy for your needs, not just the discount
Halloween sales can be a good opportunity to compare prices, but the biggest advertised saving doesn't necessarily mean the best value.
Before you buy, compare the final checkout price, usable battery capacity, output power, warranty, expansion options and the cost of additional panels or accessories. Check whether a discount depends on membership or a promotional code.
Remember that battery capacity alone doesn't determine how much money you'll save. Your electricity tariff, household consumption, solar generation and charging schedule all matter.
At UK Power Tech Hub, we'll continue looking at the products, technology and practical questions that matter to UK households as the plug-in energy market develops.
