SMA Sunny Island 4200Watt Off Grid Inverter/Charger

The Sunny Island SI4248 is a bidirectional battery power converter "battery inverter and charger", ideally suited for use in stand-alone grid operation. This inverter inverter allows you to charge lead acid batteries, using power sources provided on the AC side(eg. generator, public grid, Sunny Boy). The Sunny Island SI4248 creates a 230 V AC stand-alone grid using the energy stored in the batteries, allowing stables operation of connected loads and power generation devices.

The Sunny Island service life over 20 years makes it future-proof investment and also works reliably under extreme ambient conditions, such as high temperature or excessive dust.

Other AC sources can be easily connected to the AC bus and therefore substantially increase performance on the AC side. This allow batteries and generators to be dimensional smaller. The integrated smooth startup mode allows all loads to be started safely.

Installation Site Requirements

The Sunny Island weight about 39 kg. Please take this weight into account when choosing the installation site and method of installation. In domestic installation, the unit should not be mount on plasterboard walls or similar as otherwise audible vibrations are likely to result. We recommend mounting the Sunny Island to a solid surface.
