Technical Support

Hi All I hope someone can assist me with my issue.

At first the sytem is running with no faults or problems just a 2 issues that I would like to sort.

My System

2x 8Kw Sunsynk Inverters connected in parallel (master in parallel B en slave in paralles A port all dip switched in "on" position)

Parallel is selected on both inverters (Mater A Phase Modbus 01 and slave Phave A Modbus 02)

Each inverter has a PV String ( master 6x 460w panels and slave 10x 460 panels, had to spilt this was due to shading)

3x Revov R100 batteries connected to a busbar en then to inverters.

1st issue

The slave will charge the battery even when timers are set not to do so when there is PV, It will only use 300-400watts and will take from grid to do so.

The master does not charge the batteries at this time.

2nd issue

The slave will use more grid power than the master.

When the system runs only on batteries everything is spit 50/50 between the inverters.

The batteries are connected to the master via CAN port but I see the master shows the bms but the slave not, not sure if this is normal as the master handles the bms.

Your help will be greatly appreciated.

Regards
