Questions, answered
Make the next
decision with clarity.
Storage is a long-term choice. Here are the questions we hear most from homeowners, installers and clean-energy teams.
Ask a specific question ↗What is a home solar energy storage system?+
It stores electricity from solar or the grid and supplies that energy later for daily loads, peak-time savings or backup power.
Can MARSTEK batteries work without solar panels?+
Yes. Grid charging is supported on the featured residential models, while solar input can be added for greater self-consumption and resilience.
Which battery chemistry is used?+
The featured MARSTEK models use LiFePO4 battery cells, selected for stable thermal behavior and long cycle life.
How long does installation take?+
Plug-in models are designed for a fast setup, while whole-home systems should be installed and commissioned by a qualified electrician.
Can storage capacity be expanded later?+
Selected VENUS E and MARS I models support parallel or additional-battery expansion. Confirm the configuration with the installer before purchase.
What can a home battery power during an outage?+
The backed-up loads depend on the inverter rating and wiring. Typical priority loads include lighting, networking, refrigeration and selected appliances.
Are the systems suitable for outdoor installation?+
Featured models are rated up to IP65, but the exact installation location, clearances and local code requirements must be checked by a professional.
How can I monitor energy production and consumption?+
Compatible models provide app, Wi-Fi, Bluetooth, Ethernet or RS-485 connectivity for monitoring and energy-management functions.
Does the system support EV charging?+
The MARSTEK ecosystem includes smart AC charging and selected VENUS E products can coordinate with a compatible portable EV charger.
How do I choose the right model?+
Start with daily energy use, critical loads, PV size, available space and local grid rules. Share these details with our team for a matched recommendation.
