Bedrock foundation Drill eight holes vertically into the bedrock using the rod unit as a template. Make the holes 20 mm wide and 250 mm deep. Use compressed air to remove any debris and water from the holes to ensure a clean bonding surface. Rod unit Make sure the rod unit fits well into the holes.

Grid-�ed system with microinverters 1. Acquire an outdoor underground cable long enough to reach from the junction box (K) on the column to the nearest fuse box inside the house. A 1-phase system needs a cable with two wires plus a surrounding shield (1-phase cable), whereas a 3-phase system needs a cable with four wires plus the shield (3-phase cable).
