AC Board - Sigenergy Gateway Single Phase - On Grid, 125A Full Backup, 63A Grid, 2 x 63A Inverters, 63A Smart Port - Bypass, Surge Diverter

Single phase on grid system with 2 x 10kW or 2 x 12kW controllers

This Sigenergy Custom Gateway has been designed for systems limited to a single-phase supply. If you need to use more equipment on-site than the grid connection can support, the Sigenergy system can be installed as a load support system. This allows the batteries to kick in when the site draws more power than the grid can supply.

To make it easier to understand, let's say a customer wants to draw 120A of load, but their grid connection can only support 80A. Previously, this was only possible with other inverter brands (such as Selectronic), but now it can be done with Sigenergy at a significantly lower cost.
