Hello everyone, we have established a system in turkey. In the system, there are 3 units of quatro 48/15000 in each phase, also mppt charge 150/85 x 6 units, Fronius eco 27, symo 20 and symo 10 available, lastly BYD LVL 15.4 kWh x 10 units available. all installations in the system are ok, but the batteries are not charging and discharging. Although the battery status shows 49% on the screen, the charge does not show any current, but it reads the voltage. I'm looking for help on this matter.
