automatically limiting the rate of voltage increase once the gassing voltage has

been reached.

Less maintenance and aging when the battery is not in use: the Storage

mode

The Storage mode kicks in whenever the battery has not been subjected to

discharge during 24 hours. In the Storage mode float voltage is reduced to

2,2V/cell (13,2V for 12V battery) to minimise gassing and corrosion of the positive

plates. Once a week the voltage is raised back to the absorption level to

'equalize' the battery. This feature prevents stratification of the electrolyte and

sulphation, a major cause of early battery failure.

Two DC outputs for charging two batteries

The main DC terminal can supply the full output current. The second output, intended for

charging a starter battery, is limited to 4A and has a slightly lower output voltage.

Increasing service life of the battery: temperature compensation

The temperature sensor (supplied with the product) serves to reduce charging voltage when

battery temperature rises. This is particularly important for maintenance-free batteries, which

could otherwise dry out by overcharging.

More on batteries and charging

Our book 'Energy Unlimited' offers further information on batteries and battery charging and

is available free of charge on our website (see www.victronenergy.com -> Support &

2.3 Self consumption – solar energy storage systems

When the Multi/Quattro is used in a configuration in which it will feed back energy to the grid

it is required to enable grid code compliance by selecting the grid code country setting with

the VEConfigure tool.

This way the Multi/Quattro can comply to the local rules.

Once set, a password will be required to disable grid code compliance or change grid code

related parameters.

If the local grid code is not supported by the Multi/Quattro an external certified interface

device should be used to connect the Multi/Quattro to the grid.

Special note for Australian customers: IEC62109.1 certification and CEC approval for off-grid

use does NOT imply approval for grid-interactive installations. Additional certification to IEC

62109.2 and AS 4777.2.2015 are required before grid-interactive systems can be

implemented. Please check Clean Energy Council website for current approvals.
