Eco-worthy inverter confusion. Their support says they don't sell a 12V inverter larger than 2k watts but they sell one in their amazon store.

Eco-Worthy's Amazon listings are a mess tbh. I've noticed they have slightly different product ranges depending on which marketplace you're buying from — their own website, Amazon UK, Amazon US, and their eBay store all seem to carry different stock. Classic case of the left hand not knowing what the right hand is doing.

That said, I'd be cautious about going above 2kW on a 12V system anyway. The cable runs become genuinely problematic — you're looking at absolutely massive conductor cross-sections to keep losses and heat manageable at those current levels. A 2kW inverter on 12V is pulling close to 180A at full load. Going bigger just multiplies that headache.

If you actually need more than 2kW continuous, it might be worth asking yourself whether a 24V or 48V bank would suit better. I made that switch in my tiny house build and it transformed the whole installation — cables become sensible sizes again.

Back to your actual question though — do you have a link to the specific Amazon listing? It's possible it's:

• A third-party seller using Eco-Worthy branding
• An older model they've discontinued but haven't delisted
• A US-spec unit that's crept onto the UK store

Worth checking the actual product description carefully for input voltage range and whether it's got UK plug certification. Some of their stuff is genuinely decent, but quality control can vary and their support clearly aren't always across their full catalogue.

Anyone else had similar runaround from their customer service? Seems like a common theme with the budget Chinese inverter brands.

@Wardy Yes, this caught me out too! I think what happens is their Amazon store is often run semi-independently or they have third-party resellers listing under their brand name. Support staff at the main company sometimes genuinely don't know what's appearing on Amazon.

Worth checking the actual product listing carefully — I've seen cases where something advertised as "12V 2000W" is actually a modified sine wave unit rather than pure sine, which explains why they might not officially acknowledge it in their pure sine range.

My advice would be to grab a screenshot of the Amazon listing and email it directly to their support asking them to confirm whether it's a genuine Eco-Worthy product. Also check the model number against their official website. Sometimes these Amazon listings are older stock or regional variants they've quietly discontinued. 🙂

Worth adding — I ran into exactly this rabbit hole when speccing the inverter for my shepherd's hut build. The 12V limitation isn't just an Eco-Worthy quirk; it's basic physics. At 2kW+ on 12V you're looking at 200A+ draw, and the cable runs become genuinely frightening.

If you legitimately need more than 2kW continuous, the honest answer is move to 24V or 48V rather than chasing a 12V unicorn. Victron's MultiPlus range makes far more sense at those power levels, and their documentation is actually trustworthy — unlike some Amazon listing written in three countries simultaneously.

What's your actual load requirement @Wardy? Because "I need more than 2kW on 12V" is sometimes an XY problem where the real fix is reconsidering the battery bank voltage entirely.

Just bin Eco-Worthy off and grab a Victron MultiPlus — yes it costs more but you won't spend three weeks arguing with Amazon chat bots about whether a product exists. 😂 Ran a 3kVA unit in my static for two years alongside a Fogstar Drift 200Ah and it just works — no mystery listings, no conflicting specs between marketplaces, support actually knows their own product range. Life's too short for inverter archaeology.

Slightly off-topic but worth mentioning — if you're hitting the ceiling on what Eco-Worthy offer at 12V, have you considered whether 24V might be the better route anyway? Once you're pushing past 2kW, the cable sizing and losses on 12V become a proper headache. A 24V system opens up a much wider inverter market too, not just from Eco-Worthy but across the board.

@BorderVanLifer makes a fair point about Victron, though I appreciate that's not everyone's budget.

In the meantime, I'd suggest screenshotting the actual Amazon listing and sending it directly to Eco-Worthy's support with the ASIN number — forces them to give you a straight answer rather than a generic response. Their support can be hit and miss depending on who picks up your ticket.
