Why Photovoltaic Inverters Show Voltage Exceeds the Line: Causes, Risks, and Modern Solutions
You've installed solar panels, but suddenly your inverter flashes a "voltage exceeds line" error. What does this mean for your energy savings? Let's cut through the jargon: photovoltaic inverters must operate within strict voltage ranges (typically 187V-242V in China) . When grid voltage surpasses these limits, inverters disconnect to prevent equipment damage – but this safety feature often becomes a recurring headache.
