Prostar NBQ2250-EU 4 in 1 pure sine wave dc to ac inverter micro 2250w designed for residential and small commercial solar PV systems. It converts DC power from solar modules into a stable pure sine wave AC output. It integrates four independent MPPT channels into a single compact unit. This setup delivers a combined maximum AC output of 2250 W.
Inverter Micro 2250W Key Features
Pure Sine Wave Output
Clean AC waveform compatible with residential grid standards and sensitive electronics.
4-in-1 Design
Four independent MPPT inputs allow connection of up to four PV modules (or strings), optimizing energy harvest per module and minimizing mismatch losses.
Grid-Tied Operation
Synchronizes to the utility grid frequency and voltage with fast response and anti-islanding protection.
Compact & Robust
IP67 rated enclosure for outdoor installation, corrosion-resistant materials, and a compact footprint for easy mounting near PV arrays.
Smart Monitoring
Built-in WiFi communication and web/cloud monitoring support for real-time production data, historical logs, and remote diagnostics.
