When you're comparing inverters power conversion setups for a solar array, the first fork in the road is whether you need a unit that adapts to different battery bank voltages or one that focuses on clean household AC power from a single battery voltage. The TRELI 4000W and the SUMRY 3.6KW take opposite approaches: the TRELI is a hybrid solar inverter with an MPPT controller that spans multiple battery voltages, while the SUMRY is a 3.6KW hybrid inverter built around a single battery voltage. Here is how they stack up.
Quick Verdict
Pick the TRELI 4000W if you want a flexible, lower-priced hybrid solar inverter that can handle a wide range of battery voltages. Pick the SUMRY 3.6KW if you want pure sine wave 120V AC output with dual output and battery-less operation. The TRELI is the more adaptable controller; the SUMRY is the more complete AC power solution.

| Product | Listed Price | Relative Price | Best For |
|---|---|---|---|
| TRELI 4000W Hybrid Solar Inverter | USD 178.80 | Multi-voltage battery banks | |
| SUMRY 3.6KW Hybrid Solar Inverter | USD 279.95 | Off-grid homes, cabins, and RVs |
Where Each Wins
TRELI wins when your battery voltage isn't settled or you want one controller that can move between different solar kit voltages. SUMRY wins when your loads need consistent AC power and you want more control over charging and output modes.
TRELI 4000W Hybrid Solar Inverter
TRELI is the pick if your solar kit might switch between battery chemistries or voltages. The product title lists support for 12V, 24V, 36V, 48V, and 96V batteries, which gives you more flexibility than a single-voltage controller. It also includes an LCD display, a USB port, and a portable design, so you can monitor charge status and power small devices directly. The controller's safety features cover overcharge, over-discharge, overload, short circuit, reverse polarity, and overheating; the temperature-responsive fan only spins when the unit gets hot, helping it last up to 5000 hours. The trade-off is that its listed focus is charge control; if you need clean household AC output, the SUMRY is more direct.
SUMRY 3.6KW Hybrid Solar Inverter
For a 24V battery bank, the SUMRY is the cleaner AC option. The title lists 3.6KW continuous power with 120V pure sine wave output and dual output, and the description adds auto recognition of 50/60Hz, which is useful for appliances that are sensitive to power quality. It includes four charging modes and four output modes, so you can set it to prioritize solar, utility, or battery. The battery-less mode can run loads directly from the PV array, and the RS485 port enables communication with a lithium battery BMS. The limitation is that it's built around a 24V battery, so it won't cover the 12V, 36V, 48V, or 96V range of the TRELI.
Final Choice
Choose the TRELI 4000W if you need a flexible MPPT controller for a solar kit and want multi-voltage battery support. Choose the SUMRY 3.6KW if you're building an off-grid backup system and need clean AC power with the convenience of battery-less operation.
