Aliexpress scammer - ISolar SMV IV 5.6kW "EASUN POWER Inverter & Charger Store" DE.

Mate, nothing says "quality product" like an inverter that arrives with the magic smoke already inside it, waiting to escape at the earliest opportunity.

Had a similar rodeo with a no-name unit off AliExpress last year during the van build — looked identical to a legitimate Easun on the listing photos, arrived smelling faintly of optimism and cheap solder. The "5.6kW" rating was apparently measured in some parallel universe where watts work differently.

The real kicker with these ISolar clones is the support situation — you get one reply from "Kevin" at 3am promising a replacement, then absolute radio silence for the rest of recorded history.

Genuine question for the thread: has anyone actually had any luck with AliExpress disputes on these? My understanding is if you pay via PayPal goods & services you've got a fighting chance, but direct card payments into the void are basically a donation to someone's yacht fund.

For anyone tempted: Fogstar, Victron, or even a second-hand legit unit from eBay will save you the blood pressure spike. The "saving" on these knockoffs evaporates the moment you factor in return shipping to a Chinese warehouse that may or may not exist.

What's the seller doing when challenged — playing dumb or going full ghostmode?

@PeakNomad the "magic smoke pre-installed" is genuinely the best way I've heard it described 😂

Painful lesson but honestly these Aliexpress inverter listings are a minefield — same PCB gets rebranded a dozen times, specs are pure fantasy, and the "store" vanishes the moment you raise a dispute.

After getting burned on a similar unit a few years back I just bit the bullet and went Victron Multiplus. Yes, it's three times the price. No, it's never made any unexpected smells.

For anyone reading this thread before making a purchase — the Fogstar batteries + proper inverter route costs more upfront but you're not rewiring everything six months later.

AliExpress has its place for passive components like cable lugs, fuses, that sort of thing. Anything with active power electronics going through it? Just don't.

@PeakNomad the pre-installed magic smoke is a premium feature, apparently. They charge extra for that.

Genuine question though — did yours at least attempt to function before releasing the smoke, or was it more of an unboxing surprise? Because I've seen both flavours with these Easun/SRNE-adjacent units and the failure modes are fascinatingly varied.

My garden office setup nearly went the same route before I bit the bullet and went Victron. The price difference stings initially but the Victron hasn't once tried to redecorate the shed interior with carbonised components, which I consider a baseline requirement.

The AliExpress "inverter charger" category is basically a lottery where the prize is occasionally a functional device and the booby prize is a fire risk with a warranty that evaporates the moment you raise a dispute.

@TracyAllen the "premium feature" framing is spot on unfortunately.

Worth flagging for anyone considering these units — the ISolar/EASUN range uses the same internal architecture as a dozen other rebadged Chinese inverters (Voltronic, MPP Solar derivatives). Some batches are actually tolerable. The lottery is which batch you land on, and you won't know until it either works or releases that pre-installed smoke.

The real killer with AliExpress warranty claims is the return shipping cost. Unit arrives dead, they want it sent back to Shenzhen at your expense — often costs more than the inverter itself. Always pay via a credit card that gives you Section 75 protection, or at minimum PayPal goods-and-services. That's your only realistic recourse when dealing with a DE-registered storefront that's actually shipping from Guangdong.

Victron costs more for a reason. Learned that the hard way with the shepherd's hut build.

@Macca64 good shout on flagging it. Has anyone actually had any luck with AliExpress dispute resolution on these, or is it the usual "send it back to China at your own cost which exceeds the refund" situation?

Asking because I'm currently speccing out my motorhome build and was very tempted by some of these units purely on price. The ISolar/Easun stuff keeps appearing in searches and the specs look suspiciously generous for the money.

Ended up going with a Victron Multiplus compact instead — considerably more painful on the wallet but at least the magic smoke stays where it belongs.

Is there a rough price point where these budget inverter/chargers become a reasonable gamble, or is it genuinely false economy every time? Curious whether anyone's had a long-term survivor from these AliExpress stores.
