Yes, the basic setup is plug & play: plug it into a wall socket and pair it in the app. That gives 800 W to the grid. For up to 2,500 W, choose professional single-phase installation on a dedicated circuit.
Does more capacity also mean more power?
No. Capacity (kWh) is the amount of stored energy, power (W) determines how fast you supply. The Venus E 3.0 stores 5.12 kWh and supplies 800 W to the grid, or up to 2,500 W with professional installation.
Can I add another Venus E later?
Yes. You can link up to three units per phase. With a SmartBox that can grow to nine across three phases, 46.08 kWh in total.
Can the Venus E stand outside?
Yes, the unit is rated IP65 and, according to the specifications, suitable for indoor and outdoor use. The operating temperature range is -20 to 55 °C.
Can it supply power during an outage?
The Venus E has a separate backup output (Euro socket): 2,500 VA continuous and briefly 3,500 VA (10 seconds). Only what you plug into it receives power. Never connect the grid and backup sockets to the mains at the same time.
What if I do not have a P1 meter?
This version comes without the CT003 P1 meter. Marstek also lists other compatible meters, such as the HomeWizard P1 meter. If you have no compatible meter, choose the version with the meter.
