MultiPlus or Quattro Inverter/Charger

Spec: 48V Inverter/Chargers. Models available in sizes from 2.4-12kW continuous supply and 3-15kW for 30min.

Function: This is the primary ‘mini-grid’ creation device. It uses energy from the battery to create the AC grid line. It can also use energy from a generator or AC-Coupled solar systems to re-charge the battery.

May be ‘stacked’ for larger capacity and/or three-phase applications.

Color Control GX or Venus GX

Spec: User interface & control panel, web connectivity and device communications hub.

Function: Control unit and user interface that connects to the BYD BMU as well as all the Victron equipment. It can report system data to Victron’s VRM monitoring portal and/or store data locally on an SD card if internet is not available.

CCGX needs a cable to the router or a WiFi dongle. Venus is already WiFi-enabled.

The CCGX is shown on the following diagrams as it has a colour display screen. The Venus has the same core functionality and may be used instead. The Venus may be interfaced with via it’s on-board WiFi or the LAN it is connected to.

Adding DC-Coupled Solar? Use Victron’s MPPT Regulators

Spec: An extensive range of models are available in the ‘SmartSolar MPPT’ family. The 85A model will handle ~5kW of PV while the 100A model will handle ~6kW.

Function: The MPPT Reguators will allow solar PV to directly charge the batteries on the DC side of the system.

Multiple regulators may be used on one system. Use a VE.Direct cable to connect the regulator to the CCGX or Venus controller.
