PowerAssist – boosting the capacity of grid or generator power
This unique Victron feature allows the MultiPlus to supplement the capacity of the grid or
generator power. Where peak power is so often required only for a limited period, the
MultiPlus will make sure that insucient grid or generator power is immediately compen-
sated with power from the battery. When the load reduces, the spare power is used to
recharge the battery bank.
It is therefore no longer necessary to size a generator on the maximum peak load. Use the
most ecient size generator instead.
Note: this feature is available in both the MultiPlus and the Quattro.
4. Back-up system
Solar energy can also be combined with a grid connection. But a grid that suers from power failures in combination with an
insucient solar supply requires support of a generator. Instead of a MultiPlus, we recommend the Quattro, which is a MultiPlus
with built-in transfer switch to connect both the grid and a generator. This entirely automates the switching process between
the grid and the generator.
