Note: EPEVER-RTU-4G-C is compatible with the short-distance LORA wireless transmission
terminals. Up to 100 pcs LORA slave terminals can be connected through one LORA master.
Working principle:
1) The controllers, inverters, or inverter/chargers transmit the feedback data
to the EPEVER-RTU-4G-C.
2) The EPEVER-RTU-4G-C transmits the received data to the cloud server
for recording and processing via the 4G and Internet network.
3) According to the set timing task and user terminal command, the cloud
server continues to transmit the data and commands to
EPEVER-RTU-4G-C.
4) The EPEVER-RTU-4G-C transmits data and commands to the controllers,
inverters, or inverter/chargers for execution. After finished, return to Step
1) for a loop.
7 Troubleshooting
1. Check whether to supply power to the
EPEVER-RTU-4G-C.
2. Check whether the indicators are damaged.
3. If powered, check whether the positive and negative
poles of the power supply are connected inversely.
The input terminal of the EPEVER-RTU-4G-C is
equipped with anti-reverse protection. The reverse
connection shall not cause fatal damage to the
product. However, it affects the normal running
before the correct connection is restored.
After power is on, the WORK indicator will be on solid in
60 seconds. While it cannot flash after 60 seconds,
please check below:
1. Check whether the SIM card is inserted correctly.
2. Confirm the SIM card has activated the GPRS
service.
WORK indicator on solid again after running for a
period, please check:
1. Check whether the cloud server is normally running.
2. Check whether the SIM card is loose or arrear.
The product
emits smoke
with a
pungent
smell.
The actual input voltage exceeds the rated voltage of
the EPEVER-RTU-4G-C, causing the internal
components to burn out. Don't hesitate to contact the
supplier in time and send it to the manufacturer.
The device
can't register
to the
network.
1. Check whether the SIM card is inserted correctly.
2. Confirm the SIM card has activated the GPRS
service.
3. Check whether the input power is sufficient. The
input voltage shall be DC8~64V or DC5V.
Parameters
can't be
configured.
1. Check whether the connection to the PC is correct.
2. Check whether the serial port's selection is correct.
