What type of inverter/charger does the energy storage system use?

The Energy Storage System uses a MultiPlus or Quattro bidirectional inverter/charger as its main component. Note that ESS can only be installed on VE.Bus model Multis and Quattros which feature the 2nd generation microprocessor (26 or 27). All new VE.Bus Inverter/Chargers currently shipping have 2nd generation chips.

What does ESS 'inverter AC output in use' do?

This setting allows ESS only to use battery power for essential loads. It also allows battery banks to be sized to get critical loads through the night without the battery being discharged into the non-essential loads. This menu item is only visible if 'Inverter AC output in use' is enabled. 4.3.5. Feed-in excess solar charger power

How many inverters are in a 3 phase ESS?

three-phase ESS consists of at least three inverters/chargers, one in each phase. "Total of all phases": ESS symmetrically outputs the same power on all phases, attempting to keep the sum total to 0. "Individual phase": ESS regulates each separate phase to 0 W.

Why is battery discharge not allowed in ESS?

Reasons for not allowing discharge: BMS blocks discharge (DCL=0), or battery SoC level is below the 'minimum SOC' setting in ESS, when SoC is at least 3% above the set level, discharge is allowed again. A grid code is in use that requires the enabling of battery discharging by aux-inputs.
