How do I know whether my Hybrid is sufficiently charged?

The Hybrid has a clear display which shows all the relevant information. It is also possible to link your smartphone to your system. As soon as you do so you will be able to consult all the available information about the Hybrid wherever you may be.

Why is the Hybrid so heavy?

Without batteries, the Hybrid weighs less than 50 kilos. However, because the system contains a significant number of Lead Crystal batteries, the total weight is substantially higher.

Does the Hybrid have to be connected by an engineer?

Is the Hybrid supplied worldwide?

Can I do without a UPS system if I have a Hybrid?

Why should I invest in Peak Shaving?

Your network connection always has to be able to cope with major peaks. The higher the peaks, the higher the capacity costs which your energy supplier will charge. These costs can soon mount up. By using the Hybrid to reduce the maximum energy consumption from the network, you can achieve more consistent energy consumption and therefore considerably lower costs.
