Victron Energy - EasySolar-II 48/5000/70-50 MPPT 250/100 GX PMP482507010

The EasySolar-II 48/5000 GX combines an MPPT Solar Charge Controller, an inverter/charger and control hub in one enclosure. The product is easy to install, with a minimum of wiring.

The all-in-one solar power solution

The Victron EasySolar-II GX integrates the following elements:

• A MultiPlus-II inverter/charger
• A SmartSolar MPPT -Tr solar charge controller
• A GX device with a 2 x 16-character display.

These elements come prewired together inside a single unit. This greatly simplifies most installations, saving time and money.

Display and Wi-Fi

The display reads battery, inverter and solar charge controller parameters.

The same parameters can be accessed with a smartphone or other Wi-Fi enabled device.

In addition, Wi-Fi can be used to set up the system and to change settings.

Solar charge controller

The DC output of the SmartSolar MPPT is parallel wired with the DC connection of the MultiPlus-II inverter/charger.

The on/off mechanism of the MultiPlus-II also controls the SmartSolar MPPT.

GX device

The integrated GX device on the EasySolar-II includes:

• A BMS-Can interface. This can be used to connect to a compatible CAN-bus managed battery. Note that this not a VE.Can compatible port.
• A USB port
• An Ethernet port
• A VE.Direct port

The GX device controls the MultiPlus-II and the SmartSolar MPPT with respectively a VE.Bus and a VE.Direct connection.

Control over system

Want to have perfect control over your system from wherever you are whilst using your EasySolar-II 48/5000 GX, why not have a look at the Cerbo GX. Simply connect through the Victron Remote Management (VRM) portal, or access directly, using the separate GX Touch, a MFD or the VictronConnect App thanks to its added Bluetooth capability. This latest addition to the GX-range combines all the best of connectivity, redefining smart power solutions in every way.
