Interpretation of overvoltage levels:
If operating voltage of MPPT is greater than 850V, the AC output power decreases when the
voltage increases.
Overvoltage level I: Connect the product to a circuit with measures to limit instantaneous
overvoltage to a relatively low level.
Overvoltage level II: Energy-consuming equipment powered by fixed power distribution devices.
Such equipment includes appliances, portable tools and other household and
similar loads. If there are special requirements for the reliability and applicability
of such equipment, overvoltage level III shall be adopted.
Overvoltage level III: The reliability and applicability of equipment in fixed power distribution
installations must meet special requirements, including switching appliances in
fixed power distribution devices and industrial equipment permanently connect-
ed to fixed power distribution devices.
Overvoltage level IV: The equipment used in the power supply of the power distribution device,
including measuring instruments and prepositioned overcurrent protection equipment, etc.

Temperature range 0°C~+40℃
Humidity range 5% to 85%
Interpretation of environmental levels:
Outdoor inverter: The ambient air temperature range is -25°C~+60℃, suitable for pollution level 3
environment;
Indoor type II inverter: The ambient air temperature range is -25°C~+40℃, suitable for pollution
level 3 environment;
Indoor type I inverter: The ambient air temperature range is 0°C~+40℃, suitable for pollution
level 2 environment;
Interpretation of pollution levels
Pollution level 1: No pollution or only dry non-conductive pollution;
Pollution level 2: Usually there is only non-conductive pollution, but there may be temporary
conductive pollution caused by condensation;
Pollution level 3: There is conductive pollution, or non-conductive pollution becomes conductive
pollution due to condensation;
Pollution level 4: There is persistent conductive pollution, such as pollution caused by conduc-
tive dust or rain and snow.
