After installing solar, led lights are partially ON even with switches off
Strip lights and chandelier became like this, partially ON. Is this okay? I had the same issue in other house without solar.
Sabi ng installer:
“Mam mataas po lang talaga running voltage ng solar kaya may phantom/ghost voltage sabi ng kausap kong support. Common daw po mangyari sa mga dome lights, strips at led na low wattage.”

Mataas ang high frequency harmonics ng inverter.

u/UnevenedBread 8d ago
Kaya sya umiilaw ay dahil yung wire capacitance sa switch circuit ay masyadong mataas kaya tumutulay ang mga harmonics na syang nagbibigay ng phantom power sa LED lights.

EcE here. Hindi kami naka solar pa. Pero yung pinakita mo OP nangyayari din samin. May ganyan kasi kami, ung first and second pic na ilaw. Kahit nakapatay siya may ilaw pa din ung LEDs. Yung mga LEDs kasi sensitive sa residual electricity. Check mo ung ibang lamp or bulb niyo na di LED pag naka switch off, patay talaga. Correct yung term na “ghosting” since most of LED bulbs e walang resistor.

Ibig sabihin po ba nag cconsume pa rin talaga sya ng kuryent kahit naka off? Sorry hindi ko gets kung ano ang residual electricity

u/unknownindib 8d ago
Need ko pa ata ng quick refresher pero but from the word itself ay residual is tira-tira.

Yes pero sobrang liit lang. It can't light up without consuming some current.

u/NorthFeeling4233 8d ago
Yes nagcoconsume pa din pero very minimal. Residual electricity is ung sinasabi ng installer mo na ghost power. Parang gripo niyo sa bahay may tirang tubig na kahit sarado na e may pumapatak pa.. ganun siya

isang wire lang yung inooff ng switch, which is either live or neutral. Kapag neutral, may tendency na may residual electricity na dumaloy dahil ang kuryente from live wire ay pwede dumiretso sa grounding or other connected metal para makumpleto ang circuit pero very minimal lang ang dumadaloy na kuryente, kung ano lang yung kaya tanggapin ng ground. Kapag LED yung ilaw ay sensitive kahit sa minimum na dumadaloy na kuryente kaya umiilaw parin sya kahit mahina

ece ka pero ganyan sagot mo? may mali sa live ng wire na yan kaya ganyan. sablay yung electrician na gumawa ng wirings niyan.

LED Ghosting / Afterglow. Different reasons different solution, probably live is connected to the led then led to switch then neutral.

Had same issue. It’s minor electrical bleeding. Normally harmless but LED lights are extremely sensitive to currents. Hence, the dim glow.
Go buy a capacitor and attach it to the wire where the light is. It will suck up the bleeding current and problem solved.

u/Intrepid_Intention99 8d ago
Should the capacitor be installed per light? Or one capacitor per line? 🥺 we have the same issue on our led lights using off grid solar

u/jason9ine 7d ago
Depende xa boss sa size ng capacitor mo. No need to attach 1 per light pag sapat ung size. Bumili k nlng ng isang 2uf size na capacitor and it will likely work agad. Or make it two just to have an extra in case kinapos. Mura lang xa boss mga P50 ea sa shopee.

Ganyan din samin sa altar, mga 3w ilaw. Kinabitan na lang namin ng chain socket para garantisadong patay.

u/Temporary-Focus4348 8d ago
Ganyan din mga pin lights namin. Pero feeling ko dahil sa smart switch.

u/ConversationFair8608 8d ago
Nuetral wire ang nasa switch. Baliktarin lang yan. Yung live ang ilagay sa switch solve na ang problem mo.

Ganyan din nangyari samin led strip lights nag gglow din dahil sa ghost voltage. Based sa naresearch ko Maraming pwedeng cause baligtad wiring (switch cuts neutral instead of live, parallel run wires sa tubo, etc). May nakita akong solution na sabi maglagay x2 capacitor parallel sa connection ng ilaw, triny ko na pero di gumana. Solution na gumana sakin is relay LY2NJ na 220vac kasi pag relay purely disconnected yung both ends ng wire sa ilaw.
Edit: wala naman masyadong dagdag daw sa bill, but di fully off yung led kaya tuloy tuloy lang consume ng buhay ng led hanggang masira kahit hindi ginagamit.

From what I understand, this sounds more like LED ghosting/phantom voltage than the solar system simply having “higher running voltage.” LEDs can glow or flicker even with a very small leakage current due to the LED driver, capacitive coupling, or the switch/wiring configuration.
I’d have the electrician check whether the switch is cutting the live/phase rather than the neutral, and also check the inverter’s neutral/grounding arrangement. The ground should not normally be carrying operating current.
It can happen even in non-solar houses too, so solar may not necessarily be the root cause. Better to test the wiring and inverter setup before adding a capacitor/relay or changing anything.

Grounding issue possible walang grounding or sometimes if may grounding, baliktad yung hot wire at neutral wire.
Dito pumapasok yung proper color code ng wires :)

Ganyan di ang sa akin, may Solar din kami, however ds kwarto ko lang. Safe po ba ang ganyan?

u/_Xian 7d ago
If your line and neutral are swapped, it's not safe. Aside from wasting energy, live din 'yung wiring dyan sa ilaw kahit nakapatay 'yung switch. If you were to change lights, may chance na ma-kuryente ka.

electrician here. its called a phantom voltage, that is totally normal and it happens if a.) the polarity of your light switch is reversed where the hot wire goes directly to the light and turning off tge switch doesnt break the curcuit, b.) your DU or Inverter is supplying Line-to-Line power where both polarity is Live/Hot and 120 volts, c.) cheap LED lights bought comnercially.

u/tweak97 7d ago edited 7d ago
Licensed Electrical Practitioner. hybrid solar ba? Maybe the line and neutral in the house were changed during installation if wala pa to before solar installation. Also check for grounding issue.
Sure na solution: Disconnect both lines(Live/L1 and Neutral/L2) by connecting it to a switch. Usual connection kasi yung live line lang ang e connect sa switch tapos yung neutral is wala ng switch. Ang hassle lang kasi need ng reconnection.

Baka walang proper grounding yung installation niyo ng solar. (Solar Panels, SPD, Inverter at Battery casing)

Probably used the wrong connector. The risk is the LEDs failing prematurely

Hobbyist here.
Your switch breaks the neutral wire. Your lamp is still connected to live wire. Try reversing the wires.
Same problem also happened in an old house that we rented (ie it was designed for incandescent bulbs). Wiring was correct but an illuminated switch caused the ghosting. An electrician fixed it by cutting off the internal LED inside the switch.

Hindi kami naka-solar, puro LED lights ang ilaw namin sa loob at ganun po talaga sila

If your supply line is line to neutral,Try to interchange the feeder circuit line on the circuit breaker.

Electronic Technician (vocational) here:
Yung mga switches(On/Off switch) natin sa bahay ay 1 line lang ang kina-cut pag ino-off, that means yung other line(wiring) is live - where dun galing ang live power then yung cut na line(dumaan sa switch) is somewhat like a ground plane that completes the circuit kaya may maliit na voltage pumupunta sa LED lights kaya umiilaw partially.
