The Renogy 3500W 48V Inverter Charger reading covers the whole brand.
What they say
LiTime 48V 3500W All‑in‑One Inverter
- In r/SolarDIY (cross-posted to r/OffGridCabins) an owner who set up the 48V 3500W with a 100 Ah battery at an off-grid cabin found it stopped AC charging in a 15-second loop each time charging reached about 7 A from a 3,600 W dual-fuel generator running on propane, and got continuous but slow charging by capping the charge current at 10 A (November 2025).
- No other owner thread naming this model was found in r/SolarDIY, r/OffGrid or r/diySolar.
Renogy 3500W 48V 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.
Both readings are about these exact models.
What they say
LiTime 48V 3500W All‑in‑One Inverter
- On DIY Solar Forum one member who bought the 48V 3500W from litime.com for $467 found an assembly problem on arrival and sent it back on a LiTime return label for a replacement, with about a day between support replies, though he judged the build quality good (December 2024).
- Earlier in the same thread a member identified it as a relabeled SRNE all-in-one (October 2024).
Renogy 3500W 48V Inverter Charger
- On DIY Solar Forum, an owner running a 560 Ah 48 V bank gave the unit 7/10 after a month: three full AC charges and a solar charge at about 1,300 W without interruption and power-saving mode measured at about 25 W, against a 145 V solar limit, poor mounting and cover screws that strip (July 2021).
- In a 2024-25 thread another member's neighbour's unit would not grid-charge until its charge-current parameter was raised, then threw fan error code 21 whenever it warmed up and stopped working, which he called 'only 50% reliable' (June 2025); a second owner reported the same error code and said Renogy would not give a fan part number (July 2025).

LiTime 48V 3500W All‑in‑One Inverter
- THE OFF-GRID MOUNTAIN HOMESTEAD, which LiTime sent the inverter at no charge and which links it through Amazon Associate links, so it is not independent, unboxed and tested it as the first part of a budget 48 V build (November 2024, about 18,000 views) and, after running it from November 2024, called it flawless in a long-term update (July 2025, about 8,100 views).
Renogy 3500W 48V Inverter Charger
- Both channels found carry a tie.
- Will Prowse, whose channel states every video includes paid promotion or free products and who earns Amazon commission, tested it at launch in a video whose chapters cover physical installation issues and inverter output problems, and which DIY Solar Forum owners describe as a poor review (April 2021, about 530,000 views).
- Adventure Tech 2.0, in an episode 'brought to you by Renogy' with a Renogy affiliate link, unboxed it and praised BT-2 app monitoring and its 3,500 W continuous and 7,000 W surge without testing either (April 2025).
