Victron energy storage inverter working demonstration

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.

Can ESS work with a grid-tie PV inverter?

ESS can work with both Grid-tie PV inverters and/or MPPT Solar Chargers. A mix of both is also possible.

Why is an inverter better than a public grid?

An inverter offers a much weaker voltage supply than the public grid doesand that may lead to: With ESS in Optimize mode the system will always remain connected - even when the batteries are full. And although connected, the power draw is not substantial - this configuration offers the stability of the grid without additional grid consumption.

How are loads powered when PV is available?

Loads are powered from PV when that power source is available. When grid power is available, the battery will be charged with power from both the grid and the PV. Feed-in is optional and can be enabled or disabled depending on local regulations.

How does the Energy Storage System (ESS) work?

ESS can be configured to keep batteries fully charged at all times. In case of utility grid failure, battery power is used as a backup. Once the grid is restored, the batteries will be recharged either from the grid or from solar panels, when available.
