Quick Answer
The direct answer is good, but it should be emphasized more strongly that the 'reset' is for temporary glitches. If the root cause is something like overheating or loose wiring, a reset won't solve the problem, and a professional is needed to diagnose and fix the underlying issue. Also, in some cases, an inverter might not have a simple 'off and on' switch for a complete hard reset; it might involve specific breaker sequences at the service panel. Clarifying this nuance could be beneficial.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Perform a simple walkaround. Look at the inverter screen for codes, listen for weird noises, and check if it's excessively hot or dirty.
Step 2
Check your main electrical panel for any tripped breakers labeled 'Solar' or 'PV'.
Step 3
Begin the hard reset by turning OFF the AC disconnect breaker first.
Step 4
Turn OFF the DC disconnect switch, which is usually a large rotary knob on the inverter itself.
Step 5
Wait at least 5-10 minutes for the internal components to fully discharge and reset.
Step 6
Turn the DC disconnect switch back ON first.
Step 7
Turn the AC disconnect breaker back ON second.
Step 8
Wait and observe for 5-10 minutes as the inverter goes through its startup sequence. If the error returns, call a pro.

|---|---|---|---|
Standard Reset Procedure | $0 | $150-250 | 15-30 minutes |
Cleaning Vents & Exterior | $0-10 | $150+ (as part of a service call) | 10 minutes |
Minor Internal Repair (Fuse, Tightening) | N/A - Too Dangerous | $250-600 | 1-2 hours |
Inverter Replacement (Out of Warranty) | N/A - Do Not Attempt | $1500-4000+ | 3-5 hours |
When to Call a Professional Solar
- If the reset procedure doesn't fix the problem after two attempts.
- If you see or smell smoke, burning plastic, or see any burn marks on the unit.
- If the inverter is making loud popping, grinding, or sparking noises.
- If a breaker immediately trips again right after you reset it.
- If you are uncomfortable or unsure about any step of the process. There's no shame in calling for help with high-voltage equipment.
Prevention Tips
- Keep the area around your inverter clear. Give it at least a foot of breathing room on all sides.
- Wipe down the exterior and gently blow out the vents with compressed air a couple of times a year.
- Check your monitoring app weekly to get a feel for what's normal so you can spot problems early.
- Schedule an annual professional maintenance check to have all connections and performance verified.
