About Us: Results Over Revenue
InduBa is the battery division of GraNext BV. Own software, own EMS. Based in Tongeren.
The core
InduBa is the battery division of GraNext BV. Based in Tongeren, Belgium. Active in Belgium and Germany.
We are not an installer that happens to sell batteries on the side. We are a technology company that manages battery projects from A to Z. With our own software. Our own intelligence. Our own choices.
InduBa is the battery division of GraNext BV. GraNext brings together years of experience in solar energy, battery storage, high-capacity heat pumps, industrial automation, software development, networking technology and electrical engineering. That combined expertise is precisely what makes InduBa so strong. We don't just design the hardware, we also build the software that controls the entire system. From the first simulation model to the last line of code in your EMS.
How we work differently
Most companies in our sector work the way companies worked in 2015. Manual quotes. Spreadsheets. Estimates. A salesperson who drops by, names a price, and hopes it sticks.
We work differently.
Our simulator runs your project through 35,040 quarter-hour measurements per year. Not on assumptions. On your actual consumption, your actual invoice, your actual peaks. The result: a business case that is accurate to the euro.
Our EMS controls your battery. Automatically. 24 hours a day. It analyses the EPEX prices from last night, tomorrow's sunshine hours, your average consumption pattern over recent months. Then it makes the right call: buy electricity at 2 cents and pay grid fees, or wait for your own solar energy coming free from the roof. A decision every 5 seconds. Thousands per day. Automatically.
Expecting a heavy production day tomorrow? With our GridShield MAX setting, the battery prepares overnight for the next day's peak. The system charges preventively at the lowest night rate, so your peak capacity is covered before the first machine starts up. The result: a lower capacity tariff without you having to think about it.
Our client portal shows every month what your battery has delivered. No after-the-fact promises. Measurable results.
Why we are faster and sharper
We are not building our company for 2026. We are building for 2030 and beyond.
That means: no superfluous layers. No middlemen. No sales team collecting commissions. No office of 20 where 5 are actually productive.
We use advanced AI tools for engineering, simulation, documentation and client communication. Not as a gimmick. As the core of our operation. This allows a small team to deliver the same output as companies with ten times the headcount. Faster. Sharper. At lower cost.
Those lower costs, we pass on to you.
Who we work with
Why only Tier 1 manufacturers?
A battery has to last ten to fifteen years. So the question isn't only what it costs today, but whether the manufacturer is still around in ten years and whether parts are still available.
That's why we only buy from producers on the BloombergNEF Tier 1 list. Tier 1 is not a quality label but a financial measure: these are manufacturers whose projects international banks are willing to finance. Banks only do that for companies with scale, their own cell production and a balance sheet that can take a hit. Established names, not an assembly shop that's gone tomorrow.
What that gives you: a warranty backed by a company that will still be standing in ten years, and spare parts that stay available long term. A failed module in year eight should never be the reason to write off an entire installation.
Which manufacturer it becomes, we decide per project - based on your consumption profile, not on what we need to sell.

We choose per project from manufacturers on the BloombergNEF Tier 1 list. No middlemen. No importers. No agents. Short, transparent, sharp.
Results over revenue
We decline 4 out of 10 enquiries. A battery that does not pay for itself, we do not install.
In 1900, London had more than 100,000 working horses. Entire neighbourhoods lived off stables, farriers, hay trading and manure processing. Twenty years later, the horses were gone. Not because they got worse. But because the world around them changed faster than they could follow.
Every major shift starts as evolution and ends as revolution. The energy market and AI are at that tipping point. Anyone running their business today the way they did five years ago is not missing a trend. They are missing the turning point.
