Energy storage equipment installation

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.

How do I use ESS battery life?

Connect to AC when available, keep batteries charged: Use ESS Assistant and select the “Keep batteries charged” mode. • Not available in the ESS System yet, but it will be implemented. The ESS BatteryLife feature will make sure that the batteries are not unnecessarily cycled around a low SoC.

Should I install an em24 energy meter in a 3-phase system?

It is generally recommended to install an EM24 Energy Meter in a 3-phase system instead of an ET340 Energy Meter. The reason is the different aggregation methods used by them.

How do I prevent a solar charger from feeding energy to the grid?

Policy 4: Prevent feeding energy to the grid: There are two options here; first - use ESS, but do not enable Solar charger excess feed-in and it will always be connected to the grid. Or, use the Virtual Switch with ignore AC-Input. Policy 5: Connected to mains, no feedback: Use ESS, select the “Keep batteries charged” mode.

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.
