If a balcony solar inverter shows zero or unexpectedly low output, first check sunlight and shading, then compare the inverter’s own indicator with its monitoring app. A blank app does not necessarily mean generation has stopped. Check only accessible external controls; do not open the inverter, work on wiring, or disconnect DC cables. Use the manual for your exact model to interpret any light or fault code.
Start with safe, external checks
- Check daylight and shading. Confirm the panels are receiving sunlight and look for obvious shade or debris from a safe position. Output changes with available sunlight. On some TSUN models, a PV-low warning commonly appears in the morning or at dusk and normally clears; a warning that persists in full daylight deserves attention. This behavior is model-specific, not a universal rule. See the TSUN manual.
- Compare the inverter with the app. Note the inverter’s indicator and the app or portal status, along with the time and any exact code. If the inverter appears online but production data is missing, the issue may be monitoring or network communication rather than generation. Deye distinguishes communication trouble from an inverter fault, and platform or cloud behavior can affect displayed data. Check the manual for your model before treating an app reading as proof the system has stopped. See the Deye manual and Mango monitoring guidance.
- Check accessible external controls. From a safe position, see whether the plug is fully seated and whether the relevant socket switch or clearly labeled AC breaker is off or tripped. Do not open an electrical panel or attempt wiring repairs. If a breaker trips again after being reset, stop and call a qualified electrician or solar technician. Hoymiles includes checking that AC breakers are closed in its troubleshooting guidance; that is not authorization to work inside a panel. See the Hoymiles manual.
- Look up the exact fault code. Codes and reset steps vary across brands and models. TSUN’s listed causes include a disconnected AC grid; grid over- or under-voltage or frequency; low PV voltage; overtemperature; and internal faults. Some grid warnings may clear when the grid returns to normal. Follow your model’s manual, and contact the manufacturer or distributor if a fault it identifies as persistent remains.
Use the symptom to narrow down what may be wrong
| What you observe | What it may suggest | What to do |
|---|---|---|
| The app shows offline or no production, but the inverter’s own indication does not show a fault | A monitoring or communication problem may be affecting displayed data; the app alone does not establish whether the inverter is generating. | Check the local indicator and the model’s manual. If the inverter itself shows a fault, use that code to guide the next step. |
| A PV-low warning appears at dawn or dusk | On some TSUN models, low PV input at these times is common and the warning normally disappears. | See whether it clears as daylight improves. Do not assume this behavior applies to another brand or model. |
| A fault remains during full daylight | Persistent low PV input, a grid condition, overheating, or another model-specific fault may be involved. | Record the code and consult the exact manual. Contact manufacturer or distributor support if the warning persists. |
| The AC breaker is tripped, wiring appears damaged, or the breaker trips repeatedly | There may be an AC supply or electrical fault. | Do not open the panel or keep resetting the breaker. Refer the problem to a qualified electrician or solar technician. |
Know when to stop troubleshooting
Contact the manufacturer or distributor about recurring or persistent fault codes, suspected internal faults, or problems that remain after the manual’s external checks. Damaged wiring, repeated breaker trips, and any need to measure mains voltage call for a qualified electrician or solar technician.

Do not dismantle or repair the inverter yourself. The Hoymiles HMS-300/350/400/450/500-1A manual says, “Do not attempt to dismantle or repair the microinverter!” Deye’s SUN-E(60-110)G4-EU-Q0 manual warns, “Do not disconnect the DC cables while the microinverter is producing power.” These are manufacturer instructions for specific products; follow the safety directions in the manual for your own system.
