Stackable
Start with 6, 9 or 10 kWh. Adding later is possible if the inverter and fuse box allow it.
Sungrow PowerHarbor is an all-in-one home battery. The launch names 6 to 10 kWh modules, including a stackable 10 kWh module. In our range we size 6, 9 and 10 kWh, plus examples of 15 kWh (6+9) or 20 kWh (2 x 10). Outage cover runs through EnergyBridge. How we steer it is set in your quote. We do not claim a direct Frank Energie link until that is confirmed for your install.

Why Sungrow through SolarFast?
PowerHarbor is new in our range. We keep the specs to the launch: all-in-one, stackable 6 to 10 kWh modules. No extra kW figures invented on top. If it fits your fuse box, we size it in a quote.
We check whether three-phase PowerHarbor fits your connection. Steering and any contract link follow in the advice, not as a default claim on this page.
Benefits of Sungrow. How to get more from smart storage at home
Outage cover
That kit feeds the circuits we connect. That is not a promise of uninterrupted power.
Open system
The battery stays yours. We do not lock you into a closed brand ecosystem where the pack goes dumb if you change supplier.
Installation and aftercare
Our installers fit the all-in-one system by your fuse box and enable outage cover only when that is in the quote.
Capacities we install
No webshop price. The quote shows what fits your fuse box and use, including installation.

How it works
What we do and do not know
The official PowerHarbor launch names 6 to 10 kWh modules, a stackable 10 kWh module, expansion up to 120 kWh, and EnergyBridge during an outage. We do not have a Sungrow PDF in this set, so we do not add extra kW figures or warranties that are not in that launch.
We do not treat a Frank Energie link as a given. If your install gets that link, it is in the quote.
Frequently asked questions
There is no price on this page. You get a tailored quote, with installation and the module size that fits your fuse box.
That runs through EnergyBridge. What stays on depends on the circuits we connect. That is not a promise of uninterrupted power.
The launch describes stackable 6 to 10 kWh modules. Whether adding modules in your fuse box is possible is assessed on site.
