PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
3. Max. Power Voltage (Vmpp) of PV modules should be close to best Vmp of inverter or within Vmp range to get best
performance. If one PV module can not meet this requirement, it's necessary to have several PV modules in series
connection. Refer to below table.
Note:* Vmp: panel max power point voltage.
The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.
Maximum PV module numbers in Series: Vmpp of PV module*X pcs = Best Vmp of Inverter or Vmp range
PV module numbers in Parallel: Max. charging current of inverter/Impp
Total PV module numbers=maximum PV module numbers in series*PV module numbers in parallel

5. Make sure the wires are securely connected.
CAUTION:
Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
CAUTION:
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/charger will
trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the
air conditioner.
PV Connection
CAUTION:
Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV
modules.
WARNING!
All wiring must be performed by a qualified personnel.
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 as below.
