A
SolarInfo EM Environment
Monitoring Device
Applied to PV power generation system to measure the
wind speed, wind direction and solar radiation.
B
SunBox PVS PV Array
Combiner Box
By using PV array combiner box, different strings of PV
array can be converged into the PV array string box. After
that, together with lightning arresters and circuit breakers, it
is connected to the inverter to reduce the system
installation time and increase the system safety.
C
SunBox PMD-D DC
Power Distribution Cabinet
The AC distribution unit is a distribution and protection
interface between inverter and the utility network, which
contains grid-side circuit breaker, lightning protection
devices and power meters.
D
SunBox PMD-A AC Power
Distribution Cabinet
The DC distribution unit collects the DC current from PV
arrays and feeds into the inverter, which mainly contains
DC input circuit breakers, diodes and PV lightning
protection device.
E SolarInfo
Logger
Inverter Data Acquisition
and Transmission Device
Data acquisition device is used for processing the data from
PV power plants which can be communicated with the PV
grid-connected inverter for PV power plants. It is capable of
monitoring one singular inverter and even up to 100
inverters.
