You are comparing solar energy storage quotes and the name Sigenergy keeps coming up. Except that one quote mentions SigenStor, another a Sigenergy hybrid inverter, and a third a « plug and play » battery from the same brand. It is difficult to know whether you are being offered three different products or three names for the same thing.
These are not three names for the same thing. Sigenergy is a brand, not a product — and behind the brand is an entire range. SigenStor is only one part of it, albeit the best-known one. Before pricing anything, the right approach is to place each product within the ecosystem, then see which one matches your needs.
That is exactly what this page does: it provides an overview of the Sigenergy brand and its prices in 2026, with a table by product range and a simple way to guide your choice. For details of a specific product — especially SigenStor — we will direct you to the dedicated guides. Here, we take a broader view.
Sigenergy is not a single product: it is a range
Sigenergy is often summed up as « the all-in-one battery ». That is an oversimplification. The brand designs an ecosystem of residential and commercial energy equipment, designed to work together through the same app and under the same manufacturer warranty.
In practical terms, three product families structure the range you will come across in France:
- SigenStor — the all-in-one system that combines an inverter, battery and more in a single enclosure. It is the flagship product and the one generating most of the searches.
- Energy storage batteries — the « storage » section alone, in stackable modules, for adding or extending capacity.
- Hybrid inverters — the power electronics that manage solar panels, the battery, the grid and the home.
Alongside these families, the ecosystem also includes components such as an energy management hub (often referred to as SigenHub) and power modules such as SigenPower, plus software control through the mySigen app. You do not need to know every detail. You need to know one thing: these products speak the same language and complement one another.
That is the main benefit of staying with one brand. One manufacturer, one app and one warranty for managing production, energy storage and consumption.
Sigenergy prices: a reference table by range
This is the question that brought you here. And the honest answer can be summed up in one sentence: there is no single « Sigenergy price »; there are prices by range and capacity. A « Sigenergy prices » search never produces one clear amount because the equipment is modular — you pay for what you configure.
To establish a budget before even opening a product page, here are some budget guidelines by product family, observed on the French market in 2026. These are ballpark figures to help guide you, not catalogue prices.
| Sigenergy range | What it is used for | Indicative price guide for 2026 |
|---|---|---|
| Standalone hybrid inverter | Managing solar panels + battery + grid, without integrated storage | from a few thousand euros excl. VAT, depending on power |
| Energy storage battery (per module) | Adding or extending capacity, in increments of approximately 5 kWh | a few hundred to more than €1,000 excl. VAT per installed kWh |
| All-in-one SigenStor (entry-level) | Inverter + ~8 kWh battery in a single enclosure | from approximately €6,000 excl. VAT |
| All-in-one SigenStor (high-end) | High capacity, > 20 kWh, electric vehicle options | €12,000 excl. VAT and more |
| Complete ready-to-install kit | Solar panels + SigenStor + installation or plug and play | by quote, depending on power and capacity |
Three variables affect all these figures: the inverter power, the number of stacked battery modules and the options (solar panels included, mounting, vehicle charging). That is why the price is provided by quote: it matches the exact configuration, and you only pay for what your household needs.
Key takeaway: the price ranges above are guidelines for setting a budget, not firm prices. The actual cost depends on capacity, power and installation. Only a dated quote is authoritative. Guidelines updated for 2026.
Why the price per kWh is not enough for comparison
You may be thinking that you only need to compare the price per kWh between two brands. Not so fast. With Sigenergy, the all-in-one enclosure includes the hybrid inverter and, with SigenStor, vehicle charging — components that you would have purchased separately anyway with a conventional solution. Comparing an integrated system with a simple battery price per kWh means overlooking the real calculation.
The right comparison is not « price per kWh versus price per kWh ». It is « cost of one complete system versus cost of another complete system », including installation and control.
How to read a Sigenergy quote without getting caught out
Two quotes showing the same total amount can cover very different things. To compare like for like, check four lines, in this order.
First, the actual battery capacity in kWh. A quote that mentions a « Sigenergy battery » without specifying the kWh means nothing: 5 kWh or 15 kWh is not the same budget or the same use.
Next, the inverter power in kW. A 3 kW enclosure and a 6 kW enclosure do not cost the same, and they are not both suitable for the same household.
Then, what is included. Does the quote include the solar panels? Installation? Mounting? Vehicle charging? A low price that excludes installation quickly rises once the installer is added.
Finally, excl. VAT or incl. VAT. The guidelines on this page are excl. VAT. Depending on your eligibility for reduced VAT, the difference between excl. VAT and incl. VAT changes the final figure. Always compare two quotes on the same basis.
Make this distinction, and the « Sigenergy price » is no longer a blur. You are comparing configurations, not labels.
Which Sigenergy product should you choose for your needs?
Now that the ranges have been explained, choosing becomes straightforward. There is no need to compare every datasheet: start with your situation, and each profile points to a product. Here is how to find your way.
You want an all-in-one solution without combining several brands
This is the most common situation. You want to generate, store and manage energy with one piece of equipment and one warranty. Choose SigenStor, which combines the inverter and battery in a modular enclosure.
For a family home, the 6 kW single-phase all-in-one Solar kit SigenStor with 8 kWh battery clearly illustrates the concept: a solid base that can be expanded later. You will find other configurations in the all-in-one SigenStor range, with variants such as the 6 kW single-phase kit with 10 kWh battery or the 9 kW single-phase all-in-one kit, depending on the desired capacity. A 6 kW three-phase version is suitable for homes connected to a three-phase supply.
To understand exactly how SigenStor works — its architecture, battery chemistry and step-by-step sizing method — the complete SigenStor guide goes into the product details. This page does not repeat them: it directs you there.
You only want to add energy storage
Do you already have solar panels or a compatible inverter, and only need the battery? In that case, you do not need a complete system but a storage module. The plug and play batteries bring together ready-to-connect storage solutions, sized in increments according to how much you consume in the evening and at night.
You are just starting out and want an affordable entry point
There is no need to target a high-end system from the outset. If you want to test self-consumption and the brand's ecosystem without a major investment, a compact format is sufficient. The 3000W plug and play Sigenergy solar kit is an excellent first step: powerful enough to cover a good part of your daytime consumption, simple enough to get started quickly and upgradeable later.
You are still unsure about the overall power
If the real question is not the brand but system sizing — how many kWp to install on your roof — then look at your consumption first, not the catalogue. To compare configurations suited to your profile, browse our self-consumption kits: this is the right starting point before committing to a brand or capacity.
SigenStor, battery, inverter: what does each one do?
One confusion comes up time and again, so let us clear it up. Many people think that SigenStor and « Sigenergy battery » refer to the same thing. In reality, the battery is only one of the components contained in SigenStor.
Think of it this way. The hybrid inverter is the electrical brain: it decides at every moment where the current goes, from the solar panels to the home, battery or grid. The battery is the reservoir: it stores the day's surplus for the evening. SigenStor, meanwhile, is not a third category alongside them — it is the enclosure that brings the two together, along with control and, depending on the model, vehicle charging.
The practical rule follows from this. If you are starting from scratch, SigenStor avoids combining brands. If you already have compatible electronics, a standalone battery is sufficient. And if a quote contrasts « Sigenergy inverter » with « SigenStor », they do not cover the same scope: one is a component, the other a complete system. Never compare the two prices as they stand.
What the brand brings beyond the equipment
Choosing Sigenergy is not just about choosing a battery or an inverter. It means entering a system in which the components communicate with one another.
The mySigen app controls the entire system: real-time production monitoring, balancing between storage, immediate consumption and surplus injection, and optimisation according to time-of-use tariffs. In short, once the equipment has been installed, the system manages the priority between your uses itself.
Another advantage is consistent warranty coverage. When the inverter, battery and control system come from a single manufacturer, you have one point of contact if there is a problem — not three manufacturers passing responsibility from one to another. For equipment expected to last fifteen years, this matters just as much as the purchase price.
Regarding grants and taxation, the French framework in 2026 (self-consumption bonus, reduced VAT under certain conditions, surplus purchase by EDF OA) applies to a Sigenergy installation just as it does to any other eligible photovoltaic installation. As rates change regularly, check the figures in force when you start your project — and for details relating to the all-in-one system, the SigenStor guide already covers them.
In summary: brand first, product second
Sigenergy is not a product to compare line by line: it is a range in which you choose the component that matches your needs. SigenStor for an all-in-one solution, a standalone battery to expand storage, or the 3000W format to get started. The price follows this modular logic — a few thousand euros for an inverter, from approximately €6,000 excl. VAT for an entry-level SigenStor, and more as capacity increases.
The right approach is not to search for « the Sigenergy price » in the abstract, but to start with your consumption and work back to the product. To get started, compare the configurations in the all-in-one SigenStor range, explore the plug and play batteries or establish your power requirements with our self-consumption kits.
