How to reset solar inverter

Wall-mounted hybrid solar inverter unit

Short answer: To reset a solar inverter, switch off the AC disconnect first, then the DC disconnect, wait a full five minutes, and power back on in reverse order — DC first, then AC. Powering on out of sequence can re-trigger the fault you are trying to clear. If the same fault code returns after a reset, stop resetting and call your installer.

A solar inverter that suddenly stops working often just needs a reset, not a repair. Knowing the correct reset procedure — and when NOT to reset — saves an unnecessary service call.

Solar inverter unit that may need a reset

Basic Reset Procedure

Most solar inverters reset the same basic way: turn off the AC disconnect first, then the DC disconnect, wait a full 5 minutes, then power back on in reverse order — DC first, then AC. This sequence matters. Powering back on out of order can trigger the same fault the reset was meant to clear.

Reset Methods by Situation

Situation Recommended Action
Fault code, system otherwise fine Standard AC/DC disconnect reset
Frozen or unresponsive display Power cycle via disconnects, same as above
App shows offline, inverter running fine Reset the Wi-Fi/communication module only, not the whole inverter
Repeated same fault after reset Stop resetting — call a professional

When NOT to Reset

Don’t reset repeatedly if the same fault keeps returning immediately after each attempt. That pattern points to a real hardware or wiring issue that a reset can’t fix, and repeated resets can occasionally make diagnosis harder for a technician. Also avoid resetting during active troubleshooting with a technician on the phone — they may need to see the current fault state.

After the Reset: What to Check

Once power is restored, confirm the inverter’s display or app shows normal operation, not just “on.” Check that production resumes at a level consistent with current sunlight conditions. If the fault code returns within minutes or hours, document the exact code and contact your installer rather than repeating the reset again.

Frequently Asked Questions

How long should I wait between turning off and back on?
A full 5 minutes is the standard recommendation, giving internal capacitors time to fully discharge.

Is it safe to reset my inverter myself?
Yes, the AC/DC disconnect switches are designed for homeowner use — just follow the correct order.

Will resetting my inverter erase my production history?
No, production history is typically stored in the cloud or on a separate monitoring device, not lost on reset.

What if my inverter won’t turn back on after a reset?
Stop and contact your installer or manufacturer — this points to a real fault, not something a homeowner reset can resolve.

Can I reset my inverter during a power outage?
There’s no benefit — a grid-tie inverter won’t produce power during an outage regardless of reset state.
