Notes:
The Multi or Quattro used needs to be a recent type with the new microprocessor (26xxxxx or
1.
27xxxxx). All units currently shipping have this new microprocessor. Also, the Multi or Quattro
needs to run the latest 4xx firmware. Contact your Victron representative for the firmware files.
Update instructions are
The RS485 to USB interface cable from the CCGX to the AC sensor can be extended up to 100

The REL200100000 is the EM24DINAV93XISX from Carlo Gavazzi. Other EM24 models from
3.
Carlo Gavazzi can also be used, as the communication is the same. For example the
EM24DINAV53DISX, which uses Current Transformers and can therefore work in systems > 63A
per phase. Note that this model is not stocked by Victron Energy, we recommend to purchase it
locally.
2. Battery, inverter/charger and PV dimensioning
Battery size
There are several factors to take into account when dimensioning the battery:
Small batteries will be more cost effective: all available storage capacity is used every day
Small batteries will be charged and discharged with high currents: especially with lead batteries
this will reduce battery life time
Larger batteries, combined with a relatively large PV installation, can store excess power during
good days, which can then be used during several consecutive days of bad weather
Larger batteries provide longer autonomy during a power outage, requires using the UPS output
Inverter/charger size
Because it is installed parallel to the grid and the loads, the inverter size can be reduced to (much)
smaller than the max expected nominal and peak load.
For example, to cover the base load of a two person house hold, the MultiPlus xx/800 might already
be sufficient. For a household with one family, the MultiPlus xx/3000 can already manage nearly all
appliances, when not more than one of them is running at the same time. This means a MultiPlus
xx/3000 can already reduce the power consumption during late spring, summer days and early
