A.Each string solar panels should be same brand and same model.
B.The total panels power should not exceed 1.25 times of inverter input power.
C.According to the specification of the crimping terminal, determine the stripping
length (recommended 8-10, mm), crimp the wire and terminal with the crimping
pliers, and connect them to the corresponding connector housings separately, and
hear the click sound to ensure the connection is good. The picture shows the
connection of the DC terminal.
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”-”.

D.The positive and negative terminals of the panel are connected to the corresponding
terminals of the inverter. For the maximum input current value of each MPPT of
different types of inverters, please refer to the following table
：
MPPT PVA PVB PVC
12 Strings ●●●● ●●●● ●●●●
11 Strings ●●●● ●●●● ●●●○
10 Strings ●●●● ●●●○ ●●●○
9 Strings ●●●○ ●●●○ ●●●○
8 Strings ●●●○ ●●●○ ●●○○
E.Panel component configuration recommendation table:
Notice: When there is a hanging string in each MPPT, it is necessary to add a dust plug
for waterproof treatment.
F.Cable specification requirements:
Notice
：
1.Under any circumstance, the total current of all strings cannot exceed the inverter's
maximum current.
2. Do not touch any working solar panels.
3. Make sure the cable is unbroken.
