- SOLARWATT Manager ready perfect system integration
Because we can store plenty of power.
The Battery flex storage system allows you to consume more of the clean energy you generate yourself – in a more efficient way. This makes you even less dependent on sunlight while minimizing the amount you draw from the grid.
- Up to 80% self-sufficiency
- Storage adaptable to system size
- Available as AC- and DC-hybrid
Tailor-made energy storage.
Battery flex energy storage offers the right amount of storage for every size and type of system. You can easily expand the capacity of your Battery flex if your household needs more.
Battery flex is a modular system consisting of two main components: The base unit with all the control electronics and the pack units, which contain the battery cells. Each pack has a storage capacity of 2.4 kWh. Up to 8 packs can be connected per base unit (AC 1-phase). For higher demand, a cluster of up to 3 base units is possible, resulting in a total possible capacity of 57.6 kWh.
Why install a battery storage system?
A power storage unit absorbs surplus solar power generated during the day and releases it in the evening and at night, when the power demand in the house is higher. Our team will do an analysis for you to check what size system is best suited to your solar production and night time usage.
SolarWatt Home App
Battery flex Monitoring Battery flex transmits its data, such as charging, discharging and state of charge to the SOLARWATT Manager.
SOLARWATT Home app visualises this data. The balance of energy supply can also be viewed on the app.
- access all energy data from everywhere
- conveniently measure and switch appliances
- benefit from the highest data security (online banking standards)
Take Back Recycling System
At the end of its service life, Solarwatt guarantees the take back and recycling of all Battery flex components via a disposal network. • base can be dropped off at e-waste collection points • packs are taken back in accordance with the Battery Act (2009)
Battery flex is designed to return as many components as possible to the raw material cycle. The base is mainly assembled by screw connections and can therefore be easily disassembled:
- The battery case is made of aluminium, can be 100 % reused
- Printed circuit board and cable go to electrical waste
- Screws and other small parts are recycled as scrap metal
