Xantrex GT Speaks in Plain English — Read the LCD First Xantrex GT grid-tie inverters (now under the Schneider Electric umbrella) do not use numeric error codes the way many brands do. Instead, the front-panel LCD shows plain-language fault messages — “DC Voltage Fault,” “AC Voltage Fault,” “Ground Fault” — that alternate with the default…
Quick answer Sungrow’s user manuals document the restart directly: if the inverter misbehaves, disconnect and reconnect the DC switch and the AC main switch. In practice that means switching the AC isolator off, then the DC isolator off, waiting one to two minutes until every light and the display are dark, then switching the DC…
Aurora (Now ABB): Read the Display Before Anything Else Aurora inverters — the PVI, TRIO, and UNO families now sold and supported under the ABB brand — report problems as Wxxx warnings and Exxx errors on the front-panel display, each with a short text message. The good news for homeowners is that the message text…
SolarEdge inverters keep their status brutally simple: a green LED for production, a blue LED for monitoring communication, and a red LED that means something is wrong. When that red light comes on, the system has detected an error and stopped producing — but the fix ranges from a two-minute power cycle to a fault…
Quick answer Fronius’s own service guidance describes an AC reset for fault conditions: switch off the AC supply, wait about five minutes, and switch it back on. For a complete reset, power the inverter down fully — AC isolator off, then the DC isolator off — wait until all lights and the display are dark,…
A Sungrow inverter that has stopped working usually falls into one of three buckets: it has no power reaching it, it is showing a fault, or it is fine but its monitoring has gone quiet. Sungrow units communicate their state through LED indicators and the iSolarCloud app, so you can narrow it down in minutes…
The Tesla Solar Gateway is the small black box that Tesla installed alongside many solar-only systems. It is one of the most confusing parts of a Tesla solar setup because Tesla uses the word “gateway” for two completely different devices. This guide explains what the little black box does, what its lights mean, and when…
SolarCity was acquired by Tesla in 2016, but millions of SolarCity-installed solar systems are still running on roofs today. If you have one, you may be wondering what inverter is actually on your wall and who is supposed to service it now. The short version: SolarCity did not make its own inverters, and your support…
If your SolarEdge inverter is blinking green and blue, take a breath — on most models this is the normal startup and standby sequence, not a fault. The green LED tracks power production and the blue LED tracks communication, and both blink while the inverter wakes up, checks the grid, and counts down to production….
SMA Sunny Boy inverters are famously reliable, which makes it all the more confusing when one locks up, drops off the monitoring portal, or sits in standby for no obvious reason. A controlled restart resolves most of these situations — but SMA’s documentation carries an important warning that other brands do not: under fault conditions,…
