Connecting the inverters
Mastervolt (RS485)
54 of 268 Solar-Log
1000/500/200
Installation
4.19 Mastervolt (RS485)
Overview
Interface integrated
Where to connect: RJ45 plug outside the housing floor.
2 pin wiring
Communication address does not have to be allocated.
Multi-string technology
Mastervolt inverters are fitted with 1 or 2 MPP trackers depending on the
model. Each string input is monitored separately and perfectly adjusted to
the connected modules. Some inverters are also divided internally into 2 or
even 3 individual inverters. For example, the QS6400 is recognised as 2
inverters each with 2 strings, an XL 15 as 3 independent XL5000s.
The Solar-Log™ automatically detects how many inverters and strings are
active during inverter detection.

Note
The order in which the inverters are displayed in the Solar-Log™ after detection
is random. We strongly recommend that you change the order of the inverters
immediately after detection at startup, in the Configuration/Basic/Inverter
dialogue box (Page 162).
The inverters can be identified using the displayed serial number.
Work steps
Switch off the inverters and the SolarLog™; Page 17

Connecting inverters to the Solar-Log
The wiring is done using the
ready-made Mastervolt data cable (optional extra; not supplied)
or
your own fabricated cable connection with RJ45 plug and terminal
block connector ( Page 15)
CAUTION
Risk of damage to the unit!
The Solar-Log™ also has an RJ45 socket, which must never be connected to
the RJ45 socket on the inverter.
Only connect the inverter using the RS485/422 B interface of the
Solar-Log™ or on the Solar-Log
1000
also via the RS485 A interface.
