Routine Maintenance
To ensure that the solar inverter can operate properly for a long term, you are advised to perform routine maintenance on it as described in this chapter.
- Before cleaning the system, connecting cables, and maintaining the grounding reliability, power off the system and ensure that the all DC switches on the solar inverter are OFF.
- If you need to open the maintenance compartment door in rainy or snowy days, take protective measures to prevent rain or snow from entering the maintenance compartment. If unavoidable, do not open the maintenance compartment door.
