Five years ago, a Static VAR Generator felt like a premium product. Not anymore.
Two things changed:
1️⃣ IGBT prices came down significantly
2️⃣ Modular system architecture made manufacturing more efficient
The result? Today, SVG and capacitor bank prices are almost neck to neck. At higher ratings, the difference is barely 10% — and sometimes even less.
At InPhase, we’ve watched this shift from the front lines. And it changes the math for every facility evaluating power factor correction:
→ Above 300 KVAr: A hybrid system makes real financial sense now. Keep your capacitor banks for slow-changing loads. Add SVG for the dynamic part. Your switching reduces, your capacitors last longer.
→ Above 700 KVAr: A full SVG solution can actually work out cheaper than a traditional capacitor bank setup.
→ Already have capacitor banks? Don’t throw them out. We retrofit them into hybrid configurations every day. It’s one of the smartest upgrades a facility can make right now.
The broader picture makes this even more urgent. KVAh billing is now active in 16 states across India. Nonlinear loads from VFDs, solar installations, data centres, and EV chargers are growing fast. The demand for precise, dynamic power factor correction is not slowing down.
We started building SVGs when most people thought capacitor banks were enough. Today, that belief is what drives us — the shift from passive to active compensation is real, and it’s accelerating.
The question is no longer whether to move to active compensation. It’s when.
