What is energy storage system (ESS)?

33 1. ESS introduction & features What is ESS? An Energy Storage System (ESS) is a specific type of power system that integrates a power grid connection with a Victron Inverter/Charger, GX device and battery system. It stores solar energy in your battery during the day for use later on when the sun stops shining.

How does ESS recharge a battery?

• Recharge: ESS will recharge the battery to the minimum SoC limit if it drops more than 5% below the minimum configured SoC. Once the minimum SoC is reached the system once again switches to Discharge disabled. 4.3.11. Limit inverter power Limit the power drawn by the Multi: ie. limit the power being inverted from DC to AC.

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: • DC coupled ESS • AC coupled ESS • Energy meter is used • Grid parallel • Essential loads are used See below drawings to get an idea of all possibilities.

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. Make use of 'off-peak tariffs' • Not available in the ESS System yet, but it will be implemented. Winter mode • The ESS BatteryLife feature will make sure that the batteries are not unnecessarily cycled around a low SoC.

What is ESS mode?

The ESS mode is configured to 'Keep batteries charged'. When using a grid-tie inverter, it is connected to the AC output as well. When grid power is available, the battery will be charged with power from both the grid and the PV. Loads are powered from PV when that power source is available.

Does ESS require battery capacity?

• Battery capacity is no longer required by the Assistant. Instead, enable battery monitor and enter the capacity on the General tab in VEConfigure. ESS design and installation manual Page 24 Comparisons to Hub Assistents
