Sell your used Longi generators, ups & solar in Islamabad
Who buys used Longi generators, ups & solar in Islamabad?
Photograph the rear nameplate square on so the type code is legible, and photograph the front face as well, because whether it carries gridlines tells a buyer at once which family it belongs to. Say whether the back is glass or polymer, since dual-glass panels are heavier and clamp differently, and give the count. Free pickup across both cities, cash on collection.

Imported
Parts usually have to be imported or sourced from the grey market, so a repair takes longer and costs more — which matters more on an older unit than the build quality does.
Nothing on a module is serviceable except the junction box and its leads, and those are matched by connector pattern rather than by brand — solar shops across Islamabad and Rawalpindi stock MC4-pattern connectors, though mating two different makes of connector is the usual cause of a hot joint. The performance warranty stays with the original installation, so a used Longi is sold on measured output rather than on paper.
What your Longi generators, ups & solar is worth
Condition decides most of it, but these are the brand-specific things that move an offer up or down.
- A module whose LR type code can be matched to a datasheet places more easily than one known only by a marketing name, because the buyer needs its exact current and dimensions before wiring it into an existing string.
- Back-contact modules are the hardest to replace like for like, since nothing else on the market shares their footprint and figures — so a matched set is wanted while a single orphan is not.
- Dual-glass panels weigh more and specify where they may be clamped, which suits structures built for them and makes them awkward on rails set up for framed single-glass modules.
- A bifacial module holds its premium only where it can be mounted with clearance behind it, because the rear face is the entire reason for the premium.
When we can only offer parts value
- An engine that will not start on fresh fuel and a new plug, or that knocks once a load is applied.
- A burnt smell, blown board or corroded transformer inside an inverter, since the board swap costs more than the unit carries.
- Panels with cracked glass, delamination or scorch marks at the junction box.
- Swollen or leaking batteries, which go the lead scrap route rather than being resold as working cells.
What raises the price on any generators, ups & solar
Brand aside, these move every offer — the generators, ups & solar page has the rest.
- The age and health of the battery bank, because a good inverter behind a dead bank is judged as an inverter alone.
- Pure sine wave output, a legible rating plate and a model whose boards and spares are still on the local market.
- For a generator, honest running hours, a service record, and whether it self-starts or carries an automatic changeover panel.
- Whether a gas conversion was done with a proper kit and the petrol side left usable, rather than improvised at the carburettor.
- Completeness: charge controller, mounting frames, MC4 leads, wheels, trolley handle and the manual all count.
