Installation
AC Output
●
SolarRiver series inverters are designed for single phase grid. Voltage range is from 180V to
260V (200V-270V for Australia), typical frequency is 50Hz. Other technical requests should
comply with the requirement of local public grid.
Model SR1K5TLA1
Cable (Cu) 4mm
Micro-Breaker 16A
Micro-breaker should be installed between inverter and grid, and its rated fault current:
30 mA ≤ I fn ≤ 300 mA ， Any load should not be connected with inverter directly.
Figure 10 Incorrect Connections between Load and Inverter
Impedance of SR inverter AC connecting dot should be less than 2Ω. To ensure reliable anti-
islanding function , PV cable should be used to ensure wire loss ＜1% than normal power.
Moreover, length between AC side and grid connecting dot should be less than 50m. Below
chart is cable length for SR3K3TLA1, section area and wire loss.
