HYXiPOWER introduced its lineup of residential string inverters, from 2 kW to 10 kW, at the event
The company also introduced string inverters for small, medium, and large-scale C&I applications in India
Its showcased utility string inverter delivers up to 350 kW AC 3-phase power
HYXiPOWER, a China-based provider of solar & storage solutions, launched its latest product lineup for residential, commercial & industrial (C&I), and utility-scale applications, at REI Expo 2025. The event also marked the company’s entry into the Indian market.
For the residential segment, the company introduced a series of string inverters that offer a range of power outputs from 2 kW to 10 kW. These are designed for up to 160% DC/AC oversizing to achieve the maximum solar yield. Since PV modules rarely operate at their nominal power due to factors such as soiling and shading, inverters paired with additional DC capacity (oversizing) can operate closer to full load for a larger portion of the day compared to systems with equivalent DC-to-AC ratios. With an IP66-rated enclosure, these inverters are promoted for both indoor and outdoor applications. They feature a module-level fault monitoring function that automatically detects and addresses any faults, even at the PV array level. Without providing many details, the company stated that this inverter series undergoes more than 1,400 performance and safety evaluation tests, including type tests and routine tests, during the designing and manufacturing stages.
The company also showcased medium-sized string inverters with power outputs (AC) ranging from 12 kW to 50 kW, developed for small C&I applications. Equipped with an undisclosed number of MPPT channels, each channel carries up to 40 A DC and supports ‘high-power’ modules (>600W).
The C&I string inverters, also on display, offer a range of power output (AC) starting from 50 kW to 125 kW, covering medium and large-scale C&I loads. The company states that these are equipped with MPPT channels that support up to 40 A (DC) input and deliver a conversion efficiency (DC-to-DC) of up to 99% to maximize solar harvesting. In addition, these inverters’ built-in system management visualizes, monitors, and controls operations of large-scale commercial projects in real-time.
For utility, HYXiPOWER introduced its 350 kW (AC) 3-phase string inverter at the event. Its MPPT channels have a capacity of up to 75 A (DC), allowing for a higher capacity PV array compared to other showcased products. It delivers full load-rated power to a grid with a short-circuit ratio (SCR) of less than 1.2 at the point of interconnection without derating and ensures system stability. SCR, which is the ratio between the short-circuit capacity of the grid at the connection point and the rated power of the inverter or plant, measures the strength of the connected grid. It measures how stiff or stable the grid voltage is when a new PV inverter is connected. High SCR means a strong grid that maintains the grid’s voltage stability, while low SCR indicates a weak grid that is prone to voltage flickers, instability, or oscillations. The company added that this inverter shuts down within 25 ms for a very weak grid and ensures operational safety.
The commercialization details of these inverters are yet unknown.
