3 phase system with 6000amp shunt issue

Hi Guy,

Just commissioned a 3 phase system using 3 x 24v/5000 quattro and a 6000 amp shunt and 2800 amps of lithium batteries with built in bms units . When the system is charging only we can see a 2000w dc load on the gx device, all batteries and inverters are connected on the shunt properly. Its like one of the chargers is reading on the shunt as a load. What can i check as the system is working perfectly and all batteries are recieving the total charge from the 3 chargers. Their is no dc system load on this install.

Hi @Revolution

It appears you have the pv charger bypassing the shunt. That 'DC Power' tile is only a calculated figure, and is showing the discrepancy your system is experiencing without the shunt registering the pv part of the charge.

On a system with no dc loads that tile would normally be disabled.
