This most advanced Energy Storage system contains battery, inverter charger and communication centre. You can be free as long as you have energy in battery.
After that you either:
- start your generator to top up battery (generator is loaded properly to gain best efficiency from combustion engine / alternator setup)
- connect your solar panels
- connect your wind turbine
- connect your water turbine
- pedal bicycle with generator to charge batteries
- other source of energy
- last one (the only one bad) – charge your batteries from the grid and escape again 🙂
Every generator is different but Victron makes it possible to reduce charging power if your generator can not deliver amount of energy required by inverter charger. So you can use small generator for more hours or bigger for less to charge up your battery.
This easy & ready to assemble energy storage will be an emergency backup system capable to run your 220-230 V rated devices.

SYSTEM Highlights
5-6 Hours of Backup
Battery backup of over 5 hours at constant 1200 Watts load and 90% battery discharge. Or you can make laundry up to 10 times of normal wash cycles till battery drop to 10%.
3000 VA Power
System can support total load of up to 2400W (5500W in peak). That's enough to support devices like TV, fridge, microwave oven, laptop & mobile chargers, router, LED lights in a 3-5 bedroom flat or house.
2 x 3.5 kWh Lithium Battery
Maintenance free, state-of-the-art Li-Ion battery suitable for application scene of high power, limited installation space, restricted load-bearing and long cycle life (up to 6000 cycles).
Advanced Battery Charging
Sophisticated battery charger that features adaptive charge technology (from grid or generator) and a high-speed AC transfer switch in a single enclosure.
Real Time Monitoring
Included Venus GX ensure that all components are working in harmony and allows you for monitoring of live data or changing settings via Victron Remote Management Portal (VRM).
WiFi/LAN Enabled
The built-in WiFi Access Point or Ethernet cable port let you either connect your smartphone (or other device), as well give you an option to connect the system to the Internet.
Works as UPS
In the event of a grid failure the inverter is automatically activated and takes over supply to the connected loads (in less than 20 milliseconds, so it's safe for computers).
Warranty
System elements comes with 5-years limited warranty with the exception of battery which is 7-years limited warranty (10 years after registration).
