Maak je Systeem Compleet
Eenvoudig uitbreidbaar
De Marstek Venus E 3.0 is ontworpen met flexibiliteit in gedachten. Elke batterij heeft een capaciteit van 5,12 kWh.
Je kunt meerdere batterijen installeren en deze koppelen via de Marstek P1-meter. Op deze manier werken alle units samen als één systeem.
Ideaal wanneer je jouw opslagcapaciteit in de toekomst wilt uitbreiden.
Noodstroom als back-up
De Marstek Venus E 3.0 thuisbatterij beschikt over een ingebouwd stopcontact aan de zijkant, waarmee je direct apparaten of een verlengkabel kunt aansluiten.
Dit stopcontact biedt een betrouwbare noodstroomvoorziening, zodat je nooit zonder elektriciteit zit. Bij een stroomuitval blijven essentiële apparaten gewoon werken.
Je kunt ook permanent een apparaat aangesloten laten. Als het net uitvalt, schakelt het systeem automatisch over naar de back-upmodus — zonder dat je iets hoeft te doen.

Veelgestelde Vragen
1. What is a home battery used for?
A home battery stores excess electricity (often from solar panels) so you can use it later, helping reduce your reliance on the grid and lower your electricity costs.
2. Can a home battery work without solar panels?
Yes. A home battery can also charge from the electricity grid. However, it is most beneficial when combined with solar panels to store your own generated energy.
3. How long do home batteries usually last?
Most modern lithium batteries have a lifespan of 10–15 years and can handle thousands of charge cycles, depending on usage and operating conditions.
4. Can battery capacity be expanded later?
Our battery systems allow expansion by adding additional batteries. This allows you to increase your energy storage capacity if your energy needs grow.
5. Are home batteries safe?
Yes, definitely. Modern home batteries include built-in safety systems such as a Battery Management System (BMS) that protects against overcharging, overheating, and short circuits.
6. Where can a home battery be installed?
Home batteries can typically be installed in places such as a garage, utility room, or technical space. Installation should always follow manufacturer guidelines.
7. Do home batteries require maintenance?
Home batteries generally require very little maintenance. Regular system checks and proper installation help ensure optimal performance and lifespan.
