No outage cover
On a grid outage this tower goes off too. If you want circuits to stay on, look at HyxiPower ALL-IN or KStar ALL-IN.
Dyness Tower S3 is our three-phase tower without outage cover. Capacity from 7.1 to 21.3 kWh. The hybrid inverter is steered through Smart Grid One. There is no direct Frank Energie link, unlike HyxiPower and KStar. The battery still stays yours: no closed brand account.

Why Dyness through SolarFast?
Dyness is one line in the range, not the default for every home. We fit it when three-phase without outage cover fits, and when that EMS does the steering. We no longer say we mostly install 5 to 10 kWh Dyness. Size follows your use.
If three-phase without outage cover fits, we size the tower to your evening use. The EMS is included in the order. Internal licences are not sales copy on this page.

EMS, not Frank-direct
Tariff-based charging runs through that EMS. No direct Frank Energie app link.
Scalable
Five sizes from 7.1 to 21.3 kWh. We do not default to the smallest.
Installation and aftercare
We fit the tower, couple the hybrid inverter and set up the EMS. Circuits for an outage are not part of this line.
Capacities we install
No webshop price. The quote shows what fits your fuse box and use, including installation.
