Absolutely! We call this ‘stack charging’, and it’s one of the great features of our system. By connecting the Dock to mains power, you can also charge the Packs that are stacked on top of it. The average charging speed is around 750 W. Once the bottom Pack is full, the power is transferred to the next Pack above it using the silver-plated +/- contacts on the module.

Are you using different generations of Docks and Packs together? Then read our blog about compatibility. It clearly explains what is and isn’t possible.

During use, the stack discharges from top to bottom. This means the top Pack is fully depleted first before the one below it begins discharging. This makes it possible to ‘hotswap’ with our products. Simply remove the empty top Pack and stack a full one on top. That way, your system stays in continuous operation.

The Wattsun Charger 360 and Wattsun Charger 600 are compatible with the following products:

• Wattsun Dock 1500
• Wattsun Dock 2000
• Wattsun Dock 2000+
• Wattsun Pack 1.6
• Wattsun Pack 3000

The 360 and 600 chargers are not compatible with the Wattsun Dock 3000 and Wattsun Ventus. These have a built-in charger with which you can charge your product directly from the grid with the Wattsun Charging Cable.

Sure! You can place the Pack on all our Wattsun Dock modules. The Wattsun Pack was developed with backward compatibility in mind. For example, with a Dock 3000, you can expand up to 11 kWh of capacity.

The output power from your Dock does not change. You remain limited to the output power of the Dock 2000, Dock 2000+, and Dock 3000. Do you need more power than the Dock 2000 or Dock 2000+ can provide? Then take a look at our Dock 3000.

If the Wattsun Dock and Pack(s) are continuously kept at 100% state of charge (SOC), it negatively affects the battery’s lifespan. To prevent this, there is an intelligent charging protocol for charging on Stack. After connecting the charger, the Wattsun Dock and Pack(s) will be charged to 100%. They will only be recharged once they have dropped below 92%.

No, the Pack adds battery capacity to the Dock. The Dock is the base system of the Stack and, unlike the Pack, can be used independently.

It is possible to charge your Wattsun Dock and/or Pack using the Ventus. With 15 kWh of battery capacity on the Ventus 6000 and 20 kWh on the Ventus 12K, you have more than enough energy to power your equipment while simultaneously charging your smaller battery system.

Of course! By stacking a Wattsun Pack on top of a Dock 2000, Dock 2000+ or the Dock 3000, it will be discharged from top to bottom. If you cannot afford to lose power and the top Wattsun Pack runs out, simply lift it off the Dock and replace it with a fully charged new Pack. Our intelligent control system will automatically resume discharging from the top. This way, you never run out of power!

More and more rental partners in the Netherlands, but also in other European countries, offer Wattsun products. Take a look at our Wattsun Partner page to find a local retailers/rental partner for you.

Wattsun Ventus 6000: 15 kWh

Wattsun Ventus 12K: 20 kWh

Wattsun Dock 3000: 1.8 kWh

Wattsun Pack 3000: 2.3 kWh

Wattsun Dock 2000(+): 1.4 kWh

Wattsun Pack 1600: 1.6 kWh

Thanks to the modular design of the Wattsun Stack, the battery capacity can easily be expanded.

Our latest generation Wattsun Dock (1.8 kWh) combined with four Wattsun Packs (2.3 kWh each) provides a maximum capacity of 11 kWh.

Our previous generation Dock 2000 (1.4 kWh) combined with four Pack 1600 units (1.6 kWh each) provides a maximum capacity of 7.8 kWh.
