• Appliances such as air conditioner are required at least 2~3 minutes to restart because
it's required to have enough time to balance refrigerant gas inside of circuits. If a power
shortage occurs and recovers in a short time, it will cause damage to your connected
appliances.
• To prevent this kind of damage, please check manufacturer of air conditioner if it's
equipped with time-delay function before installation. Otherwise, this inverter will trig
overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.
6.5 PV Cable Connection
Danger of electric shock!
• The PV array will generate lethal high voltage once exposed to sunlight. Ensure
all cables are voltage-free before performing electrical operations.
• Do not connect the AC circuit breaker before finishing electrical connection.
• Make sure the PV arrays are well insulated to ground before connecting it to the
inverter.
• Make sure the voltage, current and power ratings of the PV arrays are within the
permissible range.
• Make sure polarity is correct. The inverter will not function properly if any PV
polarity is reversed.
• The 3.68kW/5kW inverter is designed with 2 MPPT trackers, if the inputs of the
PV panels are paralleled, please consult with your local distributor for technical
support.
• To avoid any malfunction, do not connect any PV Arrays with possible current
leakage to the inverter. For example, grounded PV Arrays will cause current
leakage to the inverter.
• Make sure DC switch on "OFF" position. Otherwise please use an external PV
switch to cut off the PV connection during wiring and when necessary.
• Use IEC61730 class-A Rating PV Arrays.
