SAKO SUNON-ECO 4.2KVA On-Off Grid IP20 MPPT Solar Inverter

Buy SAKO SUNON-ECO 4.2KVA On-Off Grid IP20 MPPT Solar Inverter Price in Bangladesh.

The SAKO SUNON‑ECO 4.2 KVA On‑Off Grid MPPT Solar Inverter (IP20) is a versatile hybrid solar inverter designed to bring flexibility, reliability, and efficient power conversion to homes, small offices, shops, or light commercial installations. Combining on‑grid, off‑grid, and battery‑optional modes in a single unit, it offers an adaptable solution for varied electricity conditions — from stable grid supply to solar‑only or battery‑backed backup systems.

With a rated output power of 4.2 kVA (≈ 4200 VA / 4200 W), the SUNON‑ECO can run a broad array of household or office equipment — lights, fans, TVs, refrigerators, computers, and other everyday appliances. Its pure sine wave output ensures stable, clean AC power suitable even for sensitive electronics.

Thanks to the built‑in MPPT solar charge controller and a wide PV input voltage range (90–450 VDC), this inverter can harvest solar power efficiently across a variety of panel configurations. It supports battery‑free operation (battery‑optional design) — which means you can start with a minimal setup and add battery storage later — or run with batteries (GEL, AGM, or Lithium) when backup is needed.

Modern convenience features like optional WiFi/GPRS connectivity, dual AC outputs (L1 / L2) for load separation, and an intuitive LCD + LED indicator interface give you control over system status and power distribution. The inverter’s IP20 rating makes it suitable for indoor installation in homes or offices.

Whether your goal is to build a solar‑first system, create a battery‑backup setup, or blend grid + solar + battery for maximum flexibility, the SAKO SUNON‑ECO 4.2KVA provides a dependable, efficient, and future‑ready solution.

✅ Key Features
