Maintenance of the installation

The next3 does not require any particular maintenance other than the standard O&M advised for stationary energy systems. Check with the local regulation if any further activities are required. The general preventive O&M activities advised to do regularly are: 

  • Check that the venting is not obstructed by objects or dirt.  
  • Check the connections (tightening, general condition).  

For the rest of the energy system, we can advise the following activities:

  • Check with the battery manufacturer for specific advice on battery maintenance, depending on battery technology and setup. 
  • Clean regularly you PV panels to optimize the production. Check the general status of the modules, the cabling and look for potential shadows.  

The monitoring/datalogging of the next3 will help you to understand what happens in the system and anticipate potential issues before they may arise.
