What they say
Renogy 3500W 48V Pure Sine Inverter Charger
- In a July 2025 r/vandwellers thread one owner calls a Renogy 2000 W inverter fantastic, another reports a 2000 W inverter without issues after more than 4 years, and a third is in year three with a 3000 W inverter-charger working mostly flawlessly.
- In the same thread a full-timer's 3 kW inverter output terminal snapped while being wired, and an owner with a full Renogy system since 2019 says the inverter-charger trips a 20 A shore circuit and a support ticket sat open over 30 days.
- An r/solar post titled 'Avoid Renogy' reports a PUH 2000 W inverter dead on first use from bad soldering on the switch board (August 2025), and a 2020 r/vandwellers thread reported inverter-chargers whose automatic neutral-to-ground bonding circuit did not work.
ECO-WORTHY 3500W All‑in‑One Inverter
- Reddit owners mostly report Eco-Worthy batteries holding their rated capacity and are less sure of its electronics.
- In an r/SolarDIY thread owners said their 100 Ah batteries tested to capacity and that two 12 V 260 Ah batteries in series stayed balanced for a year (February 2024), a UK owner measured nearly 102 Ah from a 12.8 V 100 Ah battery after a year on standby against 104.3 Ah new (June 2025), and in a Renogy-or-Eco-Worthy thread an owner called its batteries and panels fine and its charge controllers and inverters hit and miss (February 2026).

- 4WDing Australia ran a Renogy 3000 W and a 2000 W UPS inverter on a lap of Australia, the 3000 W at least three times a day for more than 100 days without a fault (December 2022, updated April 2024), though a commenter's 3000 W cut out after 30 seconds at 1,700 W and was returned.
- A motorhomefun owner reports a 2000 W working well for two years (March 2023), and a VW T6 Forum owner says a 3000 W has worked flawlessly (May 2026).
- On DIY Solar Forum, an owner's 1000 W pure sine inverter blew a MOSFET at 14 months, two months out of warranty, and an installer in the same thread says his firm no longer supports Renogy over reliability and service (November 2023).
ECO-WORTHY 3500W All‑in‑One Inverter
- On DIY Solar Forum an owner of the ECO-WORTHY 3500W all-in-one ran it on a 6,000 BTU window air conditioner all summer, peaking at 660 W and averaging 450 W over 10-hour days, then a 1,200 W radiator heater and a washing machine in winter, starting the largest load first; he called it an SRNE clone and advised not counting on the Wi-Fi dongle (December 2025).
