About

Keep essential appliances powered with the SAKO E-Sun Off-Grid MPPT Solar Inverter range. Available in 2 kVA and 3 kVA options, the range combines pure sine wave output with a built-in MPPT solar charge controller for managing power from compatible solar panels, batteries and an AC supply.

Each model supports configurable battery and AC or solar input priorities through its LCD settings. Smart battery protection and compatibility with LiFePO₄ batteries help provide a flexible solution for off-grid and backup power systems.

Product Features

• Built-in MPPT controller: Manages power from compatible solar panels while supporting a maximum charging efficiency of 98%.
• Wide PV input range: Supports a broad DC input voltage range, depending on the selected model.
• Low solar start-up requirement: A single compatible 36 V solar panel can start the inverter.
• Pure sine wave output: Delivers stable AC power for compatible household appliances.
• Smart battery protection: Includes low-voltage alarms, cut-off protection, recovery voltage and overcharge protection.
• LiFePO₄ compatibility: Suitable for use with compatible lithium iron phosphate battery systems.
• Configurable power priorities: Battery charging and AC or solar input priorities can be adjusted using the LCD settings.
• Automatic frequency sensing: Supports 50 Hz and 60 Hz AC input frequencies.
• Fast transfer time: Switches within 10 ms in UPS mode or 20 ms in appliance mode.
• Built-in local Wi-Fi monitoring: Monitor inverter information through the compatible app, available for iOS and Android.
