Where to start
What is happening at your plant?
- You pay excess power charges or want to use all your solar Optima How excess power is calculated
- Micro-outages stop a line that cannot fail Optima Critical What each unit sees in a micro-outage
- You need more power and the utility will not increase it Impulsa Flexible grid access guide
- Several supply points that should share solar and battery Optima Multi
- A critical part of the plant must run islanded from the grid Perpetua Selecta The first second of a blackout
- Data centre, laboratory or process that demands the cleanest supply Perpetua Elite The brochure millisecond
The switchboard, at 13:00
Covering 100 % of the active power does not empty the board
The active meter looks like a Sunday. The reactive one, like a Monday.
When the roof matches consumption, the active power crossing the transformer falls to almost zero. The motors’ reactive power still comes in from the street.
The five symptoms on the board
- The power factor at the boundary collapses. The plant did not get worse: we removed the numerator and left the denominator.
- The busbars are still loaded. Current circulates between the PV and the loads even while the meter sleeps.
- The capacitors are still in, with the motors down. With the transformer reactance they form a resonant circuit, and the fifth harmonic is amplified.
- The anti-islanding relay runs out of signals. If P and Q cross zero at the same time, it cannot tell a grid that is present from one that is gone.
- Nobody on the busbars sets the frequency. With no local inertia, how fast it falls is decided by the street.
A unit that forms the waveform changes what the board does for a living. And all of this is measured with an analyser in your own switchboard.

The solution
Geatron OGF Series
The fourth mode, because there are four. Grid-following, switched hybrid and islanded forming already existed. The fourth, On-Grid Grid-Forming, forms the grid without disconnecting from it. The four modes, side by side
What your plant gains
Power

Supply quality
- The line without micro-outages.
- It doesn’t switch over: it is already forming the grid.

01 Geatron Control Core
It sets the reference in the plant.
Illustrative
It imposes voltage and frequency with VSM control, like a synchronous machine. If the grid drops, there is nothing to switch over.
02 AC/DC modules
More power, without upgrading the grid connection.
Illustrative
The bidirectional modules add their power to the grid’s when the process asks for it. And it can be expanded.
03 DC/DC converters
No excess-power charges on the bill.
Illustrative
They discharge the battery at the peak so the meter stays within the contracted power.

Cut the grid. The plant keeps running.
Press “Simulate a grid failure” and watch the oscilloscope. At the top, in grey, the grid voltage. In the middle, in amber, what your machines receive with Geatron OGF. At the bottom, in red, a system that has to switch over to battery.
- 1The grid fails: the grey line goes flat.
- 2A switching system cuts out while it changes mode: a gap in the red line.
- 3With Geatron OGF the amber line carries on unchanged: it was already forming the grid, there is nothing to switch.
