FAQ
How does the Venus C/E work?
If the power grid is available, the Venus Energycube can save electricity costs by storing electricity when prices are low and discharging it when prices are high, or by being charged during the day via the solar panels and discharging at night. If the power grid fails, the Venus Energycube can still be charged via the solar panels and serve as an emergency power source to supply essential devices.
How can you control the input/output of the Venus C/E?
First, the Venus Energycube should be added to the Marsrtek app. Then you can manually set the charging and discharging time and power. Alternatively, you can choose the adaptive mode if it is paired with a smart meter.
Which smart meters are compatible with the Venus C/E?
Currently, Jupiter supports Marstek Smart Meter CT002 and Shelly pro 3em. If you are using a P1 meter, Marstek CT003 can be used with this for intelligent power distribution.
What charging methods does the Venus C/E support?
On one hand, the Venus Energycube can be charged via an alternating current cable with a maximum charging power of 2500 W through the power grid.
On the other hand, the Venus Energycube can also be charged by connecting to the same phase as the PV system. The maximum charging power is also 2500 W here.
On the other hand, the Venus Energycube can also be charged by connecting to the same phase as the PV system. The maximum charging power is also 2500 W here.
Can the capacity of the Venus C/E be expanded?
The capacity of the Venus C is 2560 Wh and the capacity of the Venus E is 5120 Wh. The capacity of the batteries cannot be expanded. However, you can install multiple Venus Energycubes on the same phase to increase the backup capacity on that phase accordingly.
