Both has failed..... and it is really difficult to get them replaced since this suppler isn't providing a warranty. The manufacturer is providing the warranty which is really a stressful process..... I want my money back! ### ⭐ Not robust at all. *by C***E on August 7, 2017* Bought a Cotek 3500-148 and it failed after about 6 months. It was replaced under warranty, with some protest, and I paid extra to get a SP 4000-148, thinking it would be less stressed. It started to fail after 3 months and now is in a hard fail condition, reporting a DC voltage>62, when the voltage was only 51. Nice-looking stuff but not up to Texas temperatures and humidity. ## Frequently Bought Together - Cotek SP-4000-148 Pure Sine Wave Inverter 120VAC 48VDC 4000W (SP-4000-148) - 10pcs 1 AWG-3/8 Battery Lugs,Copper Wire Lugs,UL Listed Heavy Duty Battery Cable Ends,Tubular Ring Terminals,AWG Crimp Wire Ring Lugs,Battery Terminal Connectors with 3:1 Heat Shrink Tubing - Sanuke 10pcs 1/0 AWG-3/8 Battery Lugs, UL Listed Heavy Duty Wire Lugs Ring Terminal 0 Guage terminals Battery Cable Ends/Terminal Connectors with 3:1 Heat Shrink Tubing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/88935437-cotek-sp-4000-148-pure-sine-wave-inverter-120vac-48vdc](https://www.desertcart.hr/products/88935437-cotek-sp-4000-148-pure-sine-wave-inverter-120vac-48vdc) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
