CAUTION: Before connecting to PV modules, please install a separately DC circuit breaker between the
inverter and PV modules.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV
module connection. To reduce risk of injury, please use the proper recommended cable size shown below.

WARNING: Because this inverter is non-isolated, are accepted: single crystalline, poly crystalline with class
A-rated and CIGS modules.
To avoid any malfunctions, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When
using CIGS modules, please be sure NO grounding connection.
CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it will cause damage on
inverter when lightning occurs on PV modules.
PV Module Selection:
When selecting proper PV modules, please be sure to consider the following parameters:
1.
Open circuit Voltage (Voc) of PV modules not to exceeds maximum PV array open circuit voltage of the
inverter.
2.
Open circuit Voltage (Voc) of PV modules should be higher than the start-up voltage.

CAUTION: Appliances such as air conditioner required at least 2~3 minutes to spool up because it needs to have
enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short
period of time, it may cause damage to your connected appliances. To prevent this from happening, please check
with manufacturer of air conditioner if it has time-delay function before installation. Otherwise, this inverter will
trigger overload fault and cut off output to protect your appliance but sometimes it may still causes damage to
the air conditioner.
