Victron EasySolar-II GX: Inverter, MPPT and GX in One

This Victron EasySolar-II GX review covers Victron’s all-in-one solar power unit. Inside one case are three products that would normally be wired separately: a MultiPlus-II inverter-charger, a SmartSolar MPPT-Tr solar charge controller, and a GX device with a 2 x 16-character display. Victron prewires them at the factory, so installation means connecting a battery, panels and AC. Like the Multi RS, it’s a 230V, 50Hz unit (adjustable to 60Hz), not a US split-phase inverter.

Electrical work can be dangerous: follow the manual, fuse and size every cable correctly, and use a licensed electrician for anything connected to household wiring.

What We Like

Fewer parts to wire. The MPPT’s DC output is wired in parallel with the inverter’s DC input, and the MultiPlus-II on/off switch also controls the MPPT.
Built-in GX. Ethernet, USB, VE.Direct, Wi-Fi and a BMS-Can port for compatible managed batteries, plus free VRM monitoring.
Grid-ready modes. It can store solar, feed excess back where allowed, or use an external current sensor (sold separately) to avoid grid feed-in.
PowerControl and PowerAssist to protect a small generator or grid supply.

What to Watch

230V only. North American 120V or 120/240V systems need different gear.
BMS-Can is not VE.Can. Victron notes the port only works with compatible CAN-bus batteries, not VE.Can devices.
Heavy. 26kg to 38.6kg in one piece, so plan for two people and a solid wall.
Tied together. The parts share one case, so the whole unit comes out for repair. Separate components are easier to swap.
Temperature. Operating range is -20 to +45°C, narrower than many standalone Victron units.

Who It’s For

Installers and owners of 230V cabins, small homes and backup systems who want a fast, tidy install with fewer cables. If you need US voltages or want to replace parts individually, build with separate MultiPlus-II, SmartSolar and Cerbo GX units.

Settings to Check

Battery settings for the inverter-charger and the MPPT. In a managed-battery system, the GX device and DVCC take over.
Input current limit for the grid or generator.

Setup and Troubleshooting Tips

PV overvoltage. All models have a 250V PV limit. Size strings for cold-morning open-circuit voltage.
Solar clipped on the 24V model. It allows 2,000W of PV, half the 48/3000’s 4,000W, because the same 70A of MPPT charge current carries half the power at 24V.
US wiring. 230V output only, so it doesn’t fit a 120V or 120/240V panel without extra equipment.

Why the PV Limits Differ

The maximum PV figures in the spec table follow directly from charge current multiplied by charging voltage. The 24/3000 has a 70A MPPT, and at about 28.8V that’s roughly 2,000W. The 48/3000 uses the same 70A MPPT at about 57.6V, which is roughly 4,000W. The 48/5000’s 100A MPPT at about 58V gives the 5,800W rating. Panels beyond those figures are clipped, not damaging, provided the 250V limit is respected.

Worked Example: A 48/5000 Cabin System

Strings. With a 250V limit, a panel with about 37V Voc on its label allows five in series (about 185V, still under 250V with a cold-weather margin of 10–15%). Six in series would be 222V nominal and could pass 250V on a freezing morning.
Array. Three strings of five 400W panels give 6,000W of PV, slightly above the 5,800W rating, so the controller will clip a little at midday.
Battery current. 4,000W of continuous AC output at 96% efficiency draws about 87A from a 48V bank.
Standby use. 18W of zero-load power over 24 hours is about 430Wh a day; search mode at 2W cuts that to about 50Wh when nothing is running.

Check the per-string short-circuit current against the datasheet before wiring parallel strings.

Installation Checklist

Plan for two people to lift it: 26kg for the 3kVA models and 38.6kg for the 5kVA.
Size the DC fuse and battery cables using the manual’s tables for your model.
Connect a GX-compatible battery through BMS-Can, or set charge voltages manually for a battery without communications.
Register it on VRM during commissioning so remote monitoring works from day one.

Worked examples are arithmetic estimates from the published ratings above, not test results. Real numbers depend on temperature, cable runs, battery state and load.

All-in-One or Separate Parts?

The same system can be built from a separate MultiPlus-II, a SmartSolar MPPT and a Cerbo GX. Separate parts let you choose a larger solar charger, add a second inverter later or replace one component on its own. The EasySolar-II GX saves wiring time and wall space, and arrives with its internal connections already made, which is why installers like it for compact 230V cabins and backup systems.

FAQ

Can I add more solar?

Yes, Victron systems allow more MPPTs on the DC side; the GX device manages them.

Is there a 48V 5kVA version with more PV?

The 48/5000 has the MPPT 250/100 with up to 5,800W of PV. Victron also lists 4.5kVA and 6.5kVA EasySolar-II GX models.

Does the MPPT turn off with the inverter?

Yes. Victron says the MultiPlus-II on/off switch also controls the MPPT.
