Installation Guide
On-site installation procedure PV monitoring with Xemex KWHIQ meter
Check the signal strength
The network symbol at the top right of the display indicates the signal strength of the GSM network at
that location:
Excellent
(rsrp >= -80 dBm)
Go0d
(rsrp >= -90 dBm & rsrp < -80 dBm)
Sufficient
(rsrp >= -100 dBm & rsrp< -90 dBm)
Insufficient
(rsrp >= -120 dBm & rsrp < -100 dBm)
No signal
(rsrp < -120 dBm)
If there is no signal, or if the signal is insufficient or poor (less than 2 bars at the network symbol)
the meter should be moved to a place where the signal strength is sufficient. An external antenna
can be used (optional item). In this case, the meter can remain at the location without network
coverage because an antenna is installed at the location with sufficient signal. The external antenna
is connected to the meter with a cable. The connection point (MCX connector) is located under the
communication module cover. This section is sealed. The seal must therefore first be broken and a
new seal must be placed after the antenna cable has been connected.
Installing an external antenna
1. Remove the seal from the communication module.
2. Remove the cover from the communication module.
