Faqs

A home battery stores excess solar energy for use later in the day, helping reduce electricity costs and increase energy independence.

For many homeowners, a battery can increase self-consumption of solar energy and reduce reliance on the electricity grid. The benefits depend on your energy usage, solar production, and electricity tariffs.

Most households choose between 5 kWh and 20 kWh. The ideal size depends on your daily consumption and desired level of energy independence.

In many cases, yes. Compatibility depends on your existing inverter and system design.

A hybrid inverter can manage both solar panels and battery storage, while a standard inverter only converts solar power for household use or grid export.

The best choice depends on your installation and goals. Solis offers excellent value, SMA is known for German engineering and reliability, while SolarEdge provides advanced panel-level monitoring and optimization.

A microinverter is installed behind each solar panel and allows panels to operate independently. This can improve performance on roofs with shading or multiple orientations.

Hoymiles microinverters offer panel-level optimization, easy monitoring, and strong performance for residential solar installations.

All three are trusted battery manufacturers. Dyness and Pylontech are known for reliable modular storage systems, while BYD is widely recognized as one of the world's leading battery technology providers.

Most Dyness, BYD and Pylontech systems are modular and can be expanded by adding additional battery modules.

Most modern lithium iron phosphate (LiFePO4) batteries are designed for 6,000 to 10,000+ charge cycles and typically have warranties of up to 10 years.

Victron is known worldwide for premium-quality energy systems, advanced monitoring, and exceptional flexibility for residential, marine, mobile, and off-grid applications.

Yes. Victron is one of the leading solutions for off-grid and backup power systems.

Sigenergy combines solar, battery storage, EV charging, and energy management into a single integrated ecosystem with intelligent energy management features.

Yes. Sigenergy systems are designed to manage solar generation, battery storage, household consumption, and EV charging within one platform.

Power optimizers are installed behind solar panels and allow each panel to operate independently, improving performance and monitoring.

Yes. SolarEdge systems are designed to work with their optimizer technology.

Many Wallbox charging solutions can be integrated with solar systems to maximize the use of self-generated electricity.

Wallbox chargers are compatible with most modern electric vehicles using standard European charging connections.
