Why did my solar production drop suddenly after heavy rain?
Heavy rain can temporarily reduce solar output by 10-25% due to cloud cover and water film on panels, but production should return…

Why did my solar production suddenly drop?
A sudden solar production drop is usually one of three things: temporary heavy clouds, new shade on the panels, or an inverter…

Why does my grid-tied solar inverter shut down during a power outage?
Your grid-tied inverter automatically shuts down during a power outage to protect utility workers from backfeed; it cannot operate without a live…

Why does my solar inverter display a 'Grid Fault' error and stop producing power?
A 'Grid Fault' error means your inverter detected voltage or frequency outside utility limits and shut down to protect itself and the…

Why does my solar inverter display an 'Isolation Fault' error and stop generating power?
An 'Isolation Fault' error means your inverter detected a ground fault or insulation breakdown in the DC wiring, so it shuts down…

Why does my solar inverter keep shutting off at noon?
Your inverter likely shuts down at noon because high temperatures trigger its thermal protection, or voltage spikes from peak production exceed grid…

Why does my solar inverter keep shutting off in the afternoon?
Your inverter likely shuts down in the afternoon because high temperatures trigger its thermal protection, or grid voltage rises above the inverter's…

Why does my solar inverter show 'Grid Fault' error and stop producing power?
A 'Grid Fault' error means your inverter detected voltage or frequency outside utility limits and disconnected for safety. Common causes include grid…

Why does my solar inverter show an 'Isolation Fault' error and shut down?
An 'Isolation Fault' means your inverter has detected a leakage current between the solar array and ground, usually caused by damaged wiring,…

Why does my solar inverter show an isolation fault error
An "isolation fault" error means your inverter has detected a leakage current between the solar array and ground, usually caused by moisture…

Why does my solar inverter shut down at noon when production should be highest?
Your inverter likely shuts down at noon because grid voltage rises too high when local solar production peaks, triggering its anti-islanding protection.…
