Hanchu and Sigenergy approach home battery storage from opposite directions. Hanchu focuses on getting a large amount of usable storage into a home for a competitive price. Sigenergy’s SigenStor costs more but combines the battery, inverter, backup, energy management and optional EV charging into one premium system.
That makes Hanchu vs Sigenergy less about which battery has the longest specification sheet and more about whether the SigenStor’s additional features are worth paying for.

Why choose Hanchu?
Hanchu’s appeal is straightforward: battery capacity.
The company produces modular LFP batteries designed to work with compatible hybrid inverters, allowing installers to build a storage system around the capacity and output a household actually needs.
You aren’t paying for an EV charger or an advanced all-in-one energy platform if you don’t need one. For a homeowner whose goal is simply to store excess solar during the day and use cheaper electricity overnight, that can make a lot of sense.
Strong capacity for the money
Battery economics are heavily influenced by how much usable storage you receive for the installed price.
Hanchu competes aggressively here. That makes it particularly attractive for households with relatively high overnight consumption that would otherwise need several expensive battery modules.
Before simply choosing the largest battery your budget allows, however, work out what you can realistically cycle. Our guide to what size solar battery you need explains why oversizing storage can hurt the financial case.
Simpler architecture
Hanchu is primarily the storage component rather than an entire home-energy ecosystem.
That can sound like a disadvantage next to SigenStor, but it also gives installers more freedom to design a system around compatible inverter hardware.
If you already have solar, that flexibility can be useful. See our guide to adding a battery to existing solar panels for the main retrofit options.
Why choose Sigenergy?
The SigenStor takes the opposite approach.
Rather than treating the battery as one component among several, Sigenergy has designed the system as an integrated stack combining solar conversion, battery storage, backup and energy management.
An optional DC EV charging module can also become part of the same system.
Better integration
For a new solar-and-battery installation, that integration is appealing. You avoid building an energy system from multiple separate boxes, apps and manufacturers.
The mySigen platform then provides monitoring and automated energy management across the system.
Better backup
Backup is another major difference.
Sigenergy claims a 0 ms switchover when the grid fails, effectively aiming for UPS-style continuity rather than simply restoring power after a short interruption.
Hanchu backup performance depends on the inverter and backup hardware it is paired with, so there isn’t one universal Hanchu switchover figure.
Whichever battery you choose, backup needs to be designed into the installation. Our guide to how solar batteries behave during a power cut explains why a battery does not automatically mean blackout protection.
Capacity and scalability
Both options can accommodate households that need significantly more storage than a basic 5 kWh battery.
The difference is how they get there.
Hanchu’s modular approach lets compatible battery modules be combined into larger storage systems. It is particularly compelling when the objective is simply to increase usable kilowatt-hours without dramatically increasing the budget.
Sigenergy also scales extremely well, but the modules form part of the wider SigenStor platform. This gives you a clearer upgrade route if you expect electricity consumption to rise because of an EV or heat pump.
For a household currently using 8 to 10 kWh overnight, however, paying for 25 or 30 kWh of storage simply because the system supports it rarely makes financial sense.
Cycle life and battery chemistry
Both use lithium iron phosphate chemistry.
LFP has become a popular choice for stationary storage because it offers good thermal stability and long cycle life without relying on nickel-rich chemistries.
Applicable Hanchu batteries advertise cycle-life figures reaching around 9,000 cycles, while Sigenergy advertises up to 10,000 cycles for the SigenStor.
Those numbers are useful for comparing engineering specifications, but they are not the same thing as a warranty.
A battery’s real lifespan depends on how it is cycled, its operating environment and the manufacturer’s warranty conditions. Our solar battery lifespan guide covers those factors in more detail.
Warranty comparison
This is an area where you need to compare the exact hardware on your installer quote.
Sigenergy provides defined SigenStor warranty documentation covering the battery and energy controller, with retained-capacity and energy-throughput conditions.
Hanchu warranties vary by model and route to market, so don’t accept a generic claim such as “12-year warranty” without seeing the document that applies to the exact battery being installed.
The collapse of GivEnergy in 2026 also underlined something that applies to every battery brand: a warranty is only valuable while there is a viable company and support network behind it.
We’ve covered what the GivEnergy administration means for battery owners separately.
Price and value
This is where Hanchu is designed to compete.
If two quotes provide broadly similar usable storage but the Sigenergy system costs several thousand pounds more, ask what you are receiving for the difference.
With SigenStor, the answer may include better backup, integrated energy management, a premium inverter platform, cleaner installation, future scalability and the option of DC EV charging.
If you won’t use those things, the additional spend becomes difficult to recover purely through electricity-bill savings.
Hanchu therefore makes more sense for buyers who judge the system primarily on pounds per usable kilowatt-hour.

What about EV charging?
Sigenergy has a clear advantage if an EV forms part of your longer-term energy plan.
Its optional DC EV charging module can integrate into the SigenStor tower, and compatible vehicles can potentially support bi-directional energy flows.
Hanchu doesn’t offer an equivalent integrated charger. You can still combine a Hanchu-based battery system with a conventional home EV charger, but the charger remains separate hardware.
That distinction matters less if you already have a 7 kW wallbox and are happy with it.
Which is better for an average UK home?
For a household with solar panels, no immediate plans for an EV and a fairly ordinary evening electricity load, Hanchu’s value proposition is strong. You can concentrate the budget on the storage capacity that will actually reduce grid imports.
For a larger home moving towards electrification, the equation changes.
Add a heat pump, EV, dynamic tariff and a requirement for whole-home backup, and the SigenStor’s integrated approach starts solving several problems simultaneously.
That’s why the cheaper battery isn’t automatically better value, and the more sophisticated battery isn’t automatically worth the premium.
If you’re comparing more than these two brands, our best home battery storage UK guide puts the wider market side by side.
FAQs
Is Hanchu cheaper than Sigenergy?
Generally, yes. Hanchu is positioned more aggressively on storage capacity and price, while Sigenergy charges a premium for the wider SigenStor ecosystem and its additional features.
Is Sigenergy worth the extra money?
It can be if you value its backup performance, integrated controls, expansion potential or EV charging capability. If you simply need a battery to store solar and cheap overnight electricity, the premium is harder to justify.
Which battery has the better cycle life?
Applicable Hanchu products advertise cycle figures reaching around 9,000 cycles, while Sigenergy advertises up to 10,000 cycles. Real longevity depends on usage and warranty conditions rather than the headline cycle number alone.
Can Hanchu and Sigenergy batteries work during a blackout?
Both can form part of backup-capable systems. Sigenergy integrates backup into the SigenStor ecosystem, while a Hanchu installation depends on the inverter and backup equipment selected.
Which is better, Hanchu or Sigenergy?
For straightforward storage value, Hanchu has the advantage. For a premium integrated home-energy system, Sigenergy is the stronger option.
Our Verdict
Hanchu and Sigenergy are good examples of why choosing a home battery purely from specifications doesn’t work.
Hanchu concentrates on the part most households actually need: storing a useful amount of electricity at a competitive cost. If you’re installing a battery primarily to increase solar self-consumption or exploit cheap overnight tariffs, that makes it difficult to ignore.
Sigenergy asks you to spend more but gives you considerably more system around the battery. For households planning an EV, heat pump, substantial storage expansion or serious backup capability, those additional features can justify the premium.
If neither clearly wins for your circumstances, compare them with Fox ESS as well. Our Sigenergy vs Fox ESS comparison covers the middle ground between premium integration and value.
