Solar Edge Inverter Isn't Working - Night Mode Explained

If your SolarEdge Inverter is in "Night Mode" during the daytime hours you may need to have a technician repair the system. See the troubleshooting guide below. This is usually evidence of electrical problems. Make sure you are safe and qualified to be working on SolarEdge Systems.

**SolarEdge Night Mode Trouble Shooting Sets below**

"Get Your System Back to 'Normal Mode'

An inverter can slip into Night Mode anytime it recognizes less than 6Vdc from the panels and optimizers. When this happens during daylight hours, it usually means there is an issue. Before contacting support, try following these steps:

Update the inverter firmware to at least 4.16.19
Check the junction box for loose connections
AC Voltage (all phase to N, phase to phase, phase to G and N to G measurements to the 0.1V)
Open Air string DC Voltages
Test each string individually
Take a clear picture of the inverter top and DC disconnect without covers
If applicable, take clear pictures of any thermal damage"

Please be careful and smart and safe!

Don’t forget to mention, and I see it can apply in your area, that snow covered panels will also cause a night mode situation. I’ve also come across where a breaker had tripped, HO turned it back on, and was stuck in night mode, but was actually due to a thermal event. I have seen two thermal events in the upper compartment, both a screened storedge and a newer hdwave with it being in night mode. No issues with strings.

My solar panels are on night mode... What should be my next move.. they have been out for a year now .

Best place to start would be the junction boxes?

I'm getting 10vdc before turning on the DC switch then I get .70vdc is the switch bad?

Hey man, Can you help me get access to the app. I don’t have any access because I purchased the house with the system install

[monicabrito]

Can you tell me how to Reset the password we just bought the home with the solar edge and the company that installed it went out of business.

I just realized my solar panels have been on night mode for a year and three months...so not generating power. I know, I know...I should have checked the app. Turns out the timing coincides with when Vivint switched out from the 2G/3G antennae to a 4 G one. Now my unit says "no wifi" also. Waiting for them to set up an appointment for me.

Night mode on a new SolarEdge inverter = Flashing green.

Internet communication = Blue light


If you’re making a claim this big, essentially stating that “there is an issue if blue light is on” double check your information before you spread it, many viewers could be concerned while their inverter is functioning perfectly fine.

My inverter goes into night mode but wakes up everyday. 😁

Mine doesn't work because of harmonics on grid, very frustration, never Solaredge again. Total junk.
