The laboratorySion · Valais
From cell to system
From cells to energy independence
Our laboratory tests every cell individually before it enters your battery. This process guarantees its quality.
01Receiving & sorting+
Modules arrive from certified sources. We trace and document every batch.
02Safe disassembly+
Our team dismantles the modules in the Valais laboratory under a strict protocol and removes each cell individually.
03Cell-by-cell testing+
We assess capacity, internal resistance and charge cycles. About 30% of cells are rejected.
04Assembly & matching+
Validated cells with similar characteristics are matched and assembled into consistent modules.
05Final test & certification+
We test every complete battery under real conditions and document full traceability.
How much does an installed Evolium battery cost?
CHF 5,500 for the battery, delivery and installation. The monthly maintenance subscription is separate. Confirm VAT and offer conditions with Evolium.
What do I need for the compatibility check?
Have the full installation address and a photo of your electricity meter ready: the photo is required to check compatibility. Photos of the socket and planned location remain optional. You do not need to identify a P1 port: we check the meter with you.
Does the battery work during a power cut?
The current model with a built-in inverter cannot supply your home during a power cut.
Do I need to replace my solar inverter?
The battery has its own inverter and can be added to an existing solar installation. The team checks the connections before installation.
How does the capacity guarantee work?
The subscription includes remote monitoring and replacement of modules that lose performance, subject to the contract terms. The battery remains repairable module by module.
Why add a battery to solar panels?
It stores some of the surplus generated during the day for later use. Your savings depend on your generation, consumption and electricity tariffs.
Are second-life cells tested?
Evolium tests each cell before reuse and assembles the selected cells into modules. The team then monitors the battery remotely.
Do you offer more than 10 kWh of storage?
The first model presented on the website offers 10 kWh. Contact Evolium to discuss other requirements.
