What distinguishes the Venus-A for balcony sun and modular expansion?

The Venus-A is a compact AC-coupled home battery with multiple MPPTs for direct PV connection. Ideal for balcony solar panels or small-scale systems that can be scaled up later.

  • Multiple MPPTs for flexible string configurations.
  • Back-up (EPS) possible for critical 230V consumers.
  • Modular design: start small and expand gradually.

When do you choose Venus-D with higher PV input and fast backup?

The Venus-D is an AC-coupled ESS with higher PV input (multiple MPPTs) and fast EPS switching for backup power. It can be combined with modular LFP batteries for 2.56–15.36 kWh.

  • Higher PV input via multiple MPPT trackers.
  • Fast changeover time to backup for essential circuits.
  • Expandable up to 6 battery modules for greater autonomy.

Why is the Marstek Venus-E so quick to install and universally applicable?

The Venus-E is an AC-coupled storage system with an integrated inverter and BMS. This allows it to work seamlessly with existing PV systems (including microinverters) without replacing your current string inverter.

  • Compatible with virtually any PV system via AC coupling.
  • Quick to install thanks to plug-and-play with its own inverter/BMS.
  • Scalable : up to 3 units (1-phase) or up to 9 units (3-phase, via smart control).
  • Real-time insight into production, consumption and State of Charge via the Marstek app.
  • Safe : LiFePO₄ cells , thermally stable and protected against over/under voltage and short circuit.

How do Marstek backup boxes provide safe, automatic emergency power in Europe?

With the smart backup boxes (1- and 3-phase), the backup circuit is automatically switched over in the event of a power outage. This keeps selected circuits (such as refrigerators, routers, and lighting) powered — in the Netherlands , Belgium , and Germany .

  • Automatic switchover in case of mains failure ( ATS functionality ).
  • 1-phase and 3-phase variants for residential and SMEs.
  • Compatible with Venus-A , Venus-D and Venus-E for whole house or selected circuits.
Does Marstek work with my existing inverter (string or microinverters)?

Yes. AC coupling makes Marstek systems compatible with most existing PV installations, without replacing your current inverter. This applies to Venus-E, Venus-A, and Venus-D .

Can I generate emergency power (backup) for critical consumers?

Yes. With the backup port and/or a smart backup box, the system automatically switches to island mode and supplies power to selected groups. The exact configuration depends on the single-phase/three-phase connection and local requirements.

Is this allowed in Belgium, the Netherlands and Germany?

Marstek solutions are designed for the European market. Synergrid compliance is required for Belgium ; specific grid code requirements apply in the Netherlands and Germany . We advise on the correct smart meter/CT and backup configuration for each country and grid operator.

What about warranty and service in the EU?

You receive a 10-year manufacturer's warranty on Marstek home batteries through Rebor BV. As an authorized reseller, we support the official ticket process in the Marstek app. After approval by the manufacturer, we can often replace batteries immediately , minimizing downtime.

Can I easily expand later?

Yes. All Marstek series are modular . You can add additional batteries or (for Venus-A/D) additional PV strings via the available MPPTs later, tailored to your consumption and budget.

Prices exclude 21% VAT and shipping, unless otherwise stated. Configuration and eligibility may vary by country and grid operator.
