  • Page 6 • Do not perform any servicing other than that specified in the installation instructions unless qualified to do so, or have been instructed to do so by GoodWe technical support personnel. • Solar arrays can be energized with minimal ambient light available. To ensure a safe disconnect from the system, install a high voltage DC rated disconnect, breaker, or accessible fuse box (depending on local code requirements).
  • Page 7 WARNING: Fire hazard • Do not keep combustible or flammable materials in the same room as the equipment. The GoodWe Smart Hybrid contains relays and switches which are not ignition protected. • Ensure AC, DC and ground cable sizes conform to local codes. See product manuals for minimum size requirements.
  • Page 8 Make sure all devices are de-energized or disconnected to avoid causing a spark. IMPORTANT • Use the battery types recommended by GoodWe. Follow the battery manufacturer's recommendations for installation and maintenance. • Insulate batteries appropriately against freezing temperatures. A discharged battery will freeze more easily than a charged one.
