6.2 Connection On DC Side
•Before electrical connection please ensure the inverter DC switch is
at "OFF” also disconnect AC switch, otherwise the high voltage from
inverter may cause life risk.
•Only trained authorized electrical technician can do the electric
connection also please follow the connection procedures in this
manual along with local country's regulations.
•High voltage may cause electric shocks and serious injury please do
not touch the inverter.
•Do not place flammable or explosive materials around the inverter.
Notice: The sunlight will generate voltage on the solar panels, after serial connection,
the high voltage may injure personnel, so before connect DC input cable you need
cover solar panels with light-tight materials and make sure the inverter DC switch is
at "OFF” status, otherwise high voltage may injure personnel.
•Each string's maximum open circuit voltage cannot exceed 1100Vdc,
otherwise it could lead to fire or damage the inverter. If the inverter
was damaged by higher maximum open circuit voltage (higher than
1100Vdc) product warranty will be forfeited and Growatt will not take
any responsibility.
•The inverter shall be used with IEC 61730 Class A rating PV module.
•When the group is suspended, be sure to use dust plugs to block up
to prevent entering the water into the dust.
1>Each string solar panels should be same brand and same model.
2>Under any circumstance, the maximum short circuit current should not exceed
32A.
3>The total panels power should not exceed 1.25 times of inverter input power.
4>To optimize system settings, recommend two strings with same amount solar
panels.
Notice: Connectors need to be fit with male and female terminals, before connecting
panels with inverter please make sure the positive pole and negative pole, namely the
solar panels'positve pole connect to”+” negative pole connect to”-”.
