Description
The IMAXPWR 120–180kW Photovoltaic Combiner Cabinet integrates MPPT tracking, multi‑string combining, and active circuit protection into a single, rugged enclosure. Featuring ≥99% MPPT efficiency and support for 8–16 PV strings, it maximizes solar harvest while simplifying system architecture. With IP55 outdoor rating, 4G/RS485 cloud connectivity, and AI‑powered fault prediction, this cabinet delivers reliable, high‑yield performance for commercial rooftops, ground‑mount plants, and solar‑plus‑storage projects.
MPPT + Combiner + Protection in One
The IMAXPWR Photovoltaic Combiner Cabinet integrates multi‑channel MPPT tracking, low‑loss busbar combining, and active circuit protection into a single, rugged enclosure. Supports 8 to 16 PV input strings with independent overcurrent and surge protection for each branch.
Built for 1000V / 1500V DC systems, the cabinet uses DSP digital control and resonant soft‑switching technology to achieve ≥99% MPPT conversion efficiency, boosting total generation by 15–25% under real‑world conditions.
