Tech Tip: SMA Sunny Island Smartformer

From on 02/07/2014 in Category Technology with 2 Comments

The Smartformer for Sunny Island is a 120 V/240 V autoformer that’s ideally configured for AC-coupled systems using a Sunny Island and a Sunny Boy. Getting it ready for commissioning is a simple, straight-forward process.

In this Tech Tip, Solar Academy trainer Greg Smith demonstrates how to connect each of the components in a typical grid-tied or off-grid AC-coupled system using an SMA Smartformer.

    I’ve got a project in which I have an SMA 25000TL-30 Inverter (3-Phase, 400 V). Could you please help and guide me regarding how to connect a battery bank for when the grid goes down.
