Note !
Please don’t connect the PV panel positive or negative to ground.

Use multimeter to measure module array voltage
Warning !
PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.
SR series inverters (SR3K3TLA1/SR4K4TLA1/SR4K4TLA1-PT/SR5KTLA1 ) can be connected in
series into 2-strings PV modules. Please select PV modules with excellent function and reliable
quality. Open-circuit voltage of module arrays connected in series should be
<
Max. DC (Table 3)
input voltage; operating voltage should be conformed to MPPT voltage range.
Please use PV cable to connect modules to inverter. From junction box to inverter, voltage drop is
about 1-2%. So we suggest the inverter install near PV module, in order to save cable and reduce
DC loss.
Warning !
When there is something wrong with module arrays, modules can be
connected with PV grid-tied inverter only after eliminating these problems.
