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.

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.

When does ESS automatically recharge a battery?

The system will automatically recharge the battery (from the grid) when the SOC drops 5% or more below the value of ‘Minimum SOC’ in the ESS menu. Recharge stops when it the battery is recharged up to the Minimum SOC level. 10.13. Q13: Can I use ESS in a vehicle or a boat? No, you cannot.

How do I set up an ESS system?

There are a few different ways to set an ESS system up. A combination of these are possible as well: See below drawings to get an idea of all possibilities. The first drawing shows the wiring when a MultiPlus-II is used; and the second one shows how it is wired with a MultiPlus or Quattro.

How does ESS work?

Those loads will be powered from the battery during a power failure. ESS balances the total power (L1 + L2 + L3) to be net 0 W on the meter, and symmetrically loading the inverters. In the example below the loads on L1 are 6000 W, exceeding capacity of the inverter on that phase.

Can ESS be used with a grid meter?

ESS can be used both with an external grid meter or without one. Where there is a grid meter; either a full or partial grid-parallel system can be configured to run alongside. Where there is no grid meter; all loads are connected to AC-out. And where there is a PV Inverter present that is also connected to AC out.
