Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a
high absorption voltage has been chosen, damage due to excessive gassing will
be prevented by 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 for 24 hours. In the Storage mode float voltage is reduced to 2.2 V/cell
(13.2 V for 12 V 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 4 A 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.

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 is required before grid-interactive
systems can be implemented. Please check Clean Energy Council website for
current approvals.
