Product range

InPhase power quality solutions

Five modular, scalable solutions — each addressing specific power quality challenges. Solution selection is always based on measured harmonic and reactive power data from your facility.

Active Harmonic Filters — harmonic mitigation primary function

InPhase AHF Active Harmonic Filter module

Active Harmonic Filter

AHF

⏩ Harmonic mitigation Reactive power also achievable

Primary function is comprehensive harmonic mitigation — dynamically detecting and cancelling harmonic currents in real time using IGBT-based active compensation. Reactive power compensation is also achievable, making AHF suitable where both harmonic elimination and power factor improvement are required in a single solution.

→ Real-time harmonic cancellation up to 50th order
→ 3-level IGBT topology — 98% efficiency
→ Modular — up to 32 units in parallel
→ 400V / 415V, 3Ph 4-wire systems
→ Complies with IEEE 519 and EN50160
InPhase AHF+ Advanced Active Harmonic Filter module

Advanced Active Harmonic Filter

AHF+

⏩ Advanced harmonic filtering

Advanced harmonic filtering solution designed for demanding applications — providing high-performance harmonic mitigation up to the 50th order with enhanced filtering depth. AHF+ is optimised for environments with severe harmonic distortion where standard AHF performance needs to be extended.

→ Enhanced harmonic filtering up to 50th order
→ Superior performance in high-distortion environments
→ 3-level IGBT topology — 98% efficiency
→ Modular and scalable design
→ Complies with IEEE 519 and EN50160

Static VAR Generators — reactive power compensation primary function

InPhase SVG Static VAR Generator module

Static VAR Generator

SVG

⚖ Reactive power compensation Harmonic mitigation also achievable

Primary function is reactive power compensation — providing fast, dynamic correction that stabilises voltage and improves power factor to above 0.95 for rapidly varying loads. Harmonic mitigation is also achievable, making SVG suitable where both reactive power correction and harmonic reduction are required in a single solution.

→ 5–10ms ultra-fast response — 100x faster than capacitor switching
→ Improves power factor to above 0.95
→ Three-phase load balancing capability
→ Modular — scalable from 25kVAR to multi-MVAR
→ Compatible with existing APFC panels
InPhase SVG+ Static VAR Generator with harmonic filtering module

Static VAR Generator with Harmonic Filtering

SVG+

⚖ Reactive power + harmonics

SVG+ combines reactive power compensation with basic harmonic filtering — operating in power factor mode or hybrid mode (PF + harmonics) to address both reactive power demand and moderate harmonic distortion in a single compact solution.

→ Reactive power compensation + basic harmonic filtering
→ Selectable PF mode or hybrid mode operation
→ 5–10ms response time
→ Modular and scalable design
→ Suitable for applications requiring combined correction

Hybrid Panel — passive + active combined solution

InPhase Hybrid Panel

Smart Hybrid Active Filter

Hybrid Panel

🔗 Passive + active combined

A combination of passive and active components in a single integrated panel. The passive component handles the base load — providing stable, cost-effective harmonic and reactive power correction for steady-state conditions. The active component manages dynamic and fluctuating loads in real time — ensuring consistent performance under varying conditions.

The Hybrid Panel is a cost-optimised solution for complex, mixed-load environments where a full active system would be over-specified — providing the right balance of performance and economy.

Passive component

Base load harmonic and reactive power correction — stable, cost-effective

Active component

Dynamic load management — real-time compensation for fluctuating loads

Best suited for

Complex mixed-load facilities with both stable and dynamic load profiles

Compliance

IEEE 519 and EN50160 harmonic and voltage quality standards

Why InPhase

Engineering and technology differentiators

InPhase products are built on advanced power electronics technology — designed and manufactured in India for Indian grid conditions.

98%

3-level IGBT topology

Advanced 3-level inverter technology ensures lower switching losses and superior waveform quality — delivering up to 98% efficiency and reducing energy loss and operating cost.

50th

Harmonic mitigation depth

Real-time harmonic detection and cancellation up to the 50th order — with dual quad-core DSP processors performing fast Fourier transform (FFT) analysis at over 20kHz refresh rate.

×32

Modular scalability

Up to 32 modules can be connected in parallel — allowing the system to be sized precisely for current requirements and expanded as load grows, without replacing existing equipment.

10yr

Long-term product support

10-year parts availability guarantee with high-quality film capacitors for extended operational lifespan — reducing total cost of ownership and ensuring long-term system reliability.

How we work

Audit-led. Engineered. Delivered.

pqExcel takes complete ownership of InPhase-based power quality projects — from power quality audit and harmonic study through solution design, supply, installation, commissioning, and post-installation validation.

Every solution is preceded by measurement — ensuring the correct product, correct rating, and correct installation approach for your specific site conditions. Post-commissioning, we validate performance through measurement against design targets before handover.

Power quality audit & harmonic study

Site measurement to capture harmonic profile, power factor, and load conditions — forming the basis for solution sizing and selection

Solution design & specification

Selection and sizing of the right InPhase solution — AHF, AHF+, SVG, SVG+, or Hybrid — based on measured data and load profile

Supply

Official supply of InPhase modules through authorised partner channels — ensuring product authenticity and warranty coverage

Installation & commissioning

Field installation, wiring, parameter configuration, and system commissioning — executed with safety as a priority at every stage

Post-installation validation

Post-commissioning measurement confirming THD, power factor, and compliance against IEEE 519 and EN50160 design targets
