Victron Inverters: 230 V from the Battery

An inverter connects to your battery and converts its DC voltage into 230 V AC voltage. All Victron Phoenix inverters deliver a pure sine wave—so even sensitive devices such as power supplies, pumps, or motor-driven equipment run smoothly and without humming. In ECO mode, the inverter enters a sort of standby mode as long as no load is connected, thereby conserving power from your battery.

Series Overview

Series Power Battery Data Logging Typical Application
Phoenix VE.Direct 250–1,200 VA 12V, 24V, 48V VE.Direct, Bluetooth via dongle RV, boat, small off-grid system
Phoenix Smart 1,600–5,000 VA 12V, 24V, 48V Built-in Bluetooth Larger appliances such as kettles or power tools
Phoenix Compact 1,600–2,000 VA 12V, 24V VE.Bus RV and boat with limited space
Phoenix VE.Bus 3,000–5,000 VA 12V, 24V, 48V VE.Bus, switchable between parallel and three-phase modes Vacation home, workshop, off-grid system
RS Inverter 6,000 VA 48V Built-in Bluetooth Large 48V systems

The VA rating indicates the apparent power. The continuous power in watts is slightly lower—for example, a Phoenix 12/500 delivers 500 VA and 400 W continuously. You can find the exact values on each product page.

How to Find the Right Size

The inverter’s power rating depends on your loads, not your solar panels. Add up everything you want to run at the same time, and allow for a little extra capacity. Devices with motors or compressors briefly draw many times their rated power when starting up—Phoenix inverters can handle such peaks for a moment.

Battery voltage also plays a role: the higher the power output, the greater the current on the battery side. A 2,000-W inverter draws about 170 A at 12V, but only half that at 24V. For power ratings of 2,000 VA or higher, a 24V or 48V system with thinner cables is therefore usually the better choice.

Inverter or Inverter-Charger?

A Phoenix inverter only outputs 230 V from the battery. If you also want to charge your battery from shore power or a generator and automatically switch over when grid power is available, an inverter-charger like the Victron MultiPlus is the better choice.

To see how much power your inverter is drawing from the battery, a battery monitor from the Victron battery monitoring system is helpful. With a Cerbo GX for operation and system monitoring, you can keep an eye on the entire system.

FAQ – Frequently Asked Questions About Victron Inverters

Which Victron inverter is right for me?

Add up the power of all devices that are supposed to run at the same time, and add a little extra for reserve. For a laptop, lights, and a TV, a Phoenix with 500 to 800 VA is often sufficient. A coffee maker, hair dryer, or power tools typically require 1,600 VA or more.

12V, 24V, or 48V—which is better?

That depends on your battery. Small systems in RVs usually run on 12V. For higher power output, using 24V or 48V reduces the current on the battery side, allowing for thinner cables and lower power losses.

Why is a pure sine wave important?

A pure sine wave corresponds to the current from a wall outlet. Power supplies, motors, and electronic devices operate reliably with it. Inverters with a modified sine wave can interfere with such devices or cause them to hum. All Victron Phoenix models deliver a pure sine wave.

What is the difference between the Phoenix VE.Direct and the Phoenix Smart?

The Phoenix Smart has built-in Bluetooth; you can configure it directly using the VictronConnect app. With the Phoenix VE.Direct, you’ll need the VE.Direct Bluetooth Smart dongle or a VE.Direct USB cable to do so.

Can I connect a Victron inverter directly to solar panels?

No. The inverter is connected to the battery. The solar panels charge the battery via a solar charge controller, and the inverter then draws power from the battery.

What does VA mean for inverters?

VA stands for volt-ampere, which is the apparent power. The active power in watts—the amount you can use continuously—is slightly lower. When selecting an inverter, pay attention to the continuous power rating in watts, which is listed on each product page.

How much power does an inverter consume when there’s no load?

Even without any connected devices, an inverter draws a small amount of power from the battery. In ECO mode, this idle power consumption drops significantly because the Phoenix only checks at short intervals to see if a device has been turned on.

You can find inverters from other manufacturers in the 12V to 230V Converter category.
