The Public Utilities Commission of Sri Lanka (Commission) hereby notifies its decision to hold a Stakeholder Consultation on following potential regulatory changes. These changes are aimed to enhance solar energy production by addressing the issue of inverter tripping caused by grid-overvoltage in low voltage (LV) distribution lines.

• Implementing voltage quality response modes (volt-var, volt-watt) in the inverters of grid-connected (low voltage) rooftop solar PV systems. (as the first approach). 

• Relaxing the statutory voltage limits of low voltage electricity up to 230V ±10% (as the next approach if the voltage issues persist even after the first approach).
