7.1.4 Upgrading
Context
Upgrade delay is mainly used in the upgrade scenarios where the PV power supply is
disconnected at night due to no light or unstable at dawn or dusk due to poor sunlight.
After the SUN2000 upgrade starts, if Upgrade delay is set to Enable, the upgrade package is
loaded first. After the PV power supply recovers and the activation conditions are met, the
SUN2000 automatically activates the upgrade.
Upgrade delay is set to Enable by default, which means that the upgrade can take place at day or night.
After enabling Upgrade delay, start the SUN2000 upgrade over a USB flash drive, SmartLogger, or
NMS. The SUN2000 upgrade process contains the following two stages:
1.
The monitoring component caches and loads the upgrade package.
2.
Upgrade package activation starts when the following conditions are met.
