Overview
A pure sine wave inverter and a battery charger share one housing here, so the same unit turns battery power into household current and recharges the bank from incoming power. PowerAssist technology is listed, and an LED display shows status.
Combining charging and inverting in one UL-certified box is the reason to consider it for a home or mobile battery system. Several listing fields look inconsistent, including input voltage and frequency, so verify them with Victron before planning the install.
Who it's for
Installers and owners wiring a twelve volt battery bank who need household AC plus charging from a single device. Anyone without a battery bank, or expecting solar input built in, should look at other equipment.
Pros and cons
- Inverter and charger in one housing
- Pure sine wave output
- High peak output rating listed
- PowerAssist technology listed
- Input voltage and frequency entries need confirming
- Weight not listed
- No solar charge input mentioned
- Battery bank must be supplied separately
Performance notes
Output quality comes from the pure sine wave inverter, which supplies clean AC for household loads as long as the battery bank can deliver the current. The charger side refills the bank when input power is present. PowerAssist is listed, but the listing does not explain how it behaves.
