The Orison Tower includes battery storage, power conversion electronics (inverter) and a smart networking and control system. There are no hidden fees. As well, the Tower features controllable LED lights and a Bluetooth speaker. Orison units will also be supplied with a power cord that has the appropriate plug for the location it will be used.

The Orison Tower+ includes battery storage. The expandable units leverage the power electronics and networking capabilities of the master unit. As well, the Tower+ features the same controllable LED lights and bluetooth speaker as the Tower.

The Tower comes with a high-quality Bluetooth speaker to support popular media streaming sources.

The Tower and Tower+’s are connected via a jumper cable that will be included with your purchase. The reason for this is that the Tower units have the converter and communications gear whereas the Tower+ units are only a battery extender for extra capacity.

If you have a large demand on a single circuit then you can expand your storage capacity on that circuit by plugging one or more Orison Tower+ into the Orison Tower. The + expandable units cost less by leveraging the power electronics and networking capabilities of the master unit.

For example, a modern, energy efficient refrigerator/freezer uses about one kilowatt-hour per day so a single Orison Panel would keep it going for two days in case of a blackout. If you wanted to ensure longer backup, adding one secondary unit could extend it to four days.

The number you install depends on how much energy you use per day and how many circuits you’d like to maintain operational during a blackout.  You can combine a master Orison Panel with five Tower+’s for a maximum storage capacity of 13.2kWh per Orison Tower unit.

Yes, Orison energy storage is 110-240V compatible.
