SINGLE PHASE HI 10/12kW | User Manual59
Each inverter will require a fuse isolator with surge protection and each group circuit will require an RCD. If
the batteries as supplying power to the main load during the outage, then a change over switch will also be
required or a split load can be used.
The CT coils used to limit export power must only be connected to the master. Therefore, if six inverters
are paralleled, three CT coils will be required.
Connect a RJ45 communication cable between each inverter; the order is not important since both sock-
ets are the same, so there is no IN or OUT.
Each phase must only have one master and the others set to slave.
Each inverter must have a unique Modbus number.
The maximum length of the communication cables is 2 meters (do not exceed this value).
All batteries must be connected in parallel and the MPPTs must be kept separate.
IMPORTANT: When conguring inverters in parallel for a single or three-phase, it is important to rst
check rmware versions to be all the same on all inverters. It is strongly recommended to request
rmware update on all inverters to the latest and the exact same rmware version.
IMPORTANT: All inverters in a parallel system must have their own isolating load breaker before it
goes to the parallel breaker to ensure while programming that the load outputs are isolated from
each other.
Only once conrmed all inverters are programmed correctly in parallel or three-phase then only the isolating
breakers can be switched on, which then feeds to the main load output breaker where the actual parallel or
three-phase connection is made that feeds the loads. When conguring a three-phase system using three
single-phase inverters, one per phase. It is extremely important to check phase rotation to be clockwise
feeding the inverters and to conrm the output is also clockwise on phase rotation.
NOTE:
The cables have two ends, one to be specically connected to the BMS and another one to be connect-
ed to the inverter, do not change it. If the communication is not working correctly between inverters,
then errors will appear on display. In this case, please check all settings and data cables.
All inverters in a parallel system must have their own isolating load breaker before it goes to the
parallel breaker to ensure while programming that the load outputs are isolated from each other.
The grid input can also be connected in parallel.
You cannot connect the Aux/Gen port in parallel because this causes a conict between the gen-
erator's frequency and the grid's frequency.
