Victron MultiPlus-II 48/3000/35-32 Backup Power Kit
The Victron MultiPlus-II 48/3000/35-32 Backup Power Kit is a compact single-phase backup energy solution designed for homes, small offices, and essential-load applications.
Built around the Victron MultiPlus-II 48/3000/35-32 Inverter/Charger and a Dyness DL5.0C V2 5.12 kWh lithium battery, this system provides dependable backup power during grid interruptions while allowing for future system expansion and solar integration.
System Information
The system includes a 2,400 W continuous-output Victron MultiPlus-II inverter/charger paired with one Dyness DL5.0C V2 5.12 kWh 51.2 V lithium iron phosphate battery.
The inverter can support short-duration AC loads of up to approximately 3,120 W. At a typical continuous load of 1 kW, the battery may provide approximately 5.1 hours of runtime under ideal conditions.
Actual runtime will vary depending on:
-
Connected load
-
Battery state of charge
-
Battery condition and temperature
-
Inverter and standby consumption
-
System configuration
-
Installation conditions
Avoiding unnecessary high peak loads can help extend battery runtime and improve overall system performance.

Selected pumps and motors within the inverter’s capacity
Victron PowerAssist
Victron’s PowerAssist technology can supplement a limited grid or generator supply with battery power whenever electrical demand temporarily exceeds the available AC input.
When demand reduces, available incoming power can be used to recharge the battery.
Dyness Lithium Battery Storage
The included Dyness DL5.0C V2 battery provides 5.12 kWh of lithium iron phosphate storage in a compact 51.2 V format. LiFePO₄ technology offers strong cycle life, stable performance, and efficient charging and discharging.
Additional compatible battery capacity may be added where longer backup duration is required, subject to correct system design and manufacturer requirements.
