Easun Power 4.2kW 24V/48V MPPT Solar Inverter Charger with Off Grid Dual Output Pure Sine Wave 230V 50/60Hz

Easun Power ISolar-SMH-III-4.2KW-WIFI is a compact, all-in-one MPPT hybrid inverter charger that blends solar power, battery storage, and mains or generator input to keep your loads powered with a clean, reliable pure sine wave. Designed for 24V or 48V battery banks, it delivers a robust 4.2 kW of continuous output and supports dual load outputs for flexible power management in off-grid, backup, or hybrid solar systems. The advanced LCD interface lets you tailor battery charging current, set AC vs. solar charging priority, and define acceptable input voltage to match your appliances and installation. Plus, built-in WiFi enables remote monitoring for peace of mind from anywhere.

Two key advantages set this inverter apart: a high-efficiency MPPT charger that accepts up to 6200 W of solar input and a dual-output design that powers essential loads even when some devices are pulled from the battery. With auto restart after AC recovery, overload and short-circuit protection, and a smart battery charger, it helps maximize battery life while delivering dependable power when you need it most. The unit is compatible with mains power or generators and features a cold-start function for emergency energizing in low-battery situations. For added versatility, the MPPT range (60–450 VDC) and wide AC input window (90–280 VAC or 170–280 VAC) make it suitable for a variety of solar array configurations and grid conditions.

Providing reliable power for cabins, workshops, or backup home systems, this model also includes a dedicated note: All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Warnings / Reminders

Install and wiring should comply with local electrical codes. Ensure adequate ventilation and separation from moisture. Do not exceed the specified battery bank voltage (24 V or 48 V) and MPPT input ranges. Use the LCD settings to configure charging current and AC/solar priority to match your system and avoid overloading limits. For safe operation, disconnect all sources during installation and refer to the user manual for step-by-step instructions.
