Unboxing and First Impressions
The UTL Gamma Plus 3400 arrived in sturdy packaging. Inside, I found the inverter itself, along with a battery jointer for connecting multiple batteries, a warranty card, and a user manual. The inclusion of an online registration option simplifies the warranty process, eliminating the need for excessive paperwork.
The inverter's design is clean and functional. The front panel features a multi-color LCD display, showcasing the UTL logo and the Gamma Plus series name. The patented RMPPT technology is also prominently displayed.
On the front panel, various buttons provide customization options, allowing for quick toggling of ID mode, battery type selection (tubular or lithium), and other key settings.
Technical Specifications and Features
The rear panel houses the terminal block for solar panel installation, along with LED indicators for troubleshooting any wiring issues. A sticker clearly displays the technical specifications, including the model number (3400), capacity (3kW), operating voltage (24V DC), and solar VOC range (60-106V).
The inverter boasts a three-year warranty, an upgrade from the previous two-year warranty offered on the 3350 model. This extended warranty reflects UTL's confidence in the product's reliability.
Notable features include the built-in RMPPT controller (30% more efficient than PWM controllers), pure sine wave output, a smart LCD display for real-time monitoring, BIS approval, multi-stage battery charging, and compatibility with various battery types (SMF, Gel, Tubular, Lithium) and diesel generators.
Load Test: 1-Ton Inverter Air Conditioner
For the load test, a 1-ton, three-star rated, 2022 LID inverter air conditioner was used. This AC unit was chosen to demonstrate the inverter's ability to handle typical household loads.
Initially, with the AC running, the load on the inverter was around 27%, gradually increasing as the AC compressor kicked in. The test showcased the inverter's ability to manage the fluctuating power demands of the AC.
Throughout the test, the inverter's multi-color display provided real-time feedback on power generation, load, and battery voltage. Even at full load (approximately 63% on the inverter's display), the air conditioner operated smoothly.
Conclusion and Verdict
The UTL Gamma Plus 3400 performed admirably during the load test, effortlessly powering a 1-ton inverter air conditioner. The multi-color display is a nice touch, providing clear visual cues about the system's status.
The inverter's features, including the RMPPT controller, pure sine wave output, compatibility with various battery types, and multi-stage charging, make it a versatile and powerful option.
Overall, the UTL Gamma Plus 3400 is a solid inverter that would be suitable for homes, shops or small offices. Its ability to handle significant loads, coupled with its advanced features and robust warranty, makes it a worthwhile investment.
