Hörmann SM 1-2 solar module

The Hörmann SM 1-2 solar module continuously charges the WA 24 battery of the ProMatic Akku operator. It is ideal for garages without a mains supply, where you would otherwise have to take the battery to a socket to charge it. It replaces the older SM 1-1 module, no. 436439.

Package contents

• SM 1-2 solar module, 12 W, dimensions approx. 350 × 370 mm,
• 24 V charge controller that protects the battery from overcharging,
• 45° bracket and fixing materials,
• 10 m connecting cable.

What to bear in mind during installation

• Position – face the module south, away from the shade of trees and buildings, and fix it firmly against the wind.
• Controller and battery – belong indoors, for example on a wall in the garage. Do not shorten or extend the 1.5 m cable between them.
• Cable extension – by a further 10 m, with H05-RN-F 2 × min. 1 mm² cable.
• Maintenance – remove snow and dirt that the rain does not wash off by hand.
