POWER TOWER The Ultimate Off Grid System



With the Power Tower from Hybrid Power Solutions, getting off-grid has never been easier. Avoid rising electricity & distribution costs, underwater cable maintenance for island properties and not to mention power outages. The Power Tower is the reliable, fuel-free power solution for your off-grid location.

Power Tower Base

As a completely integrated system combining solar, DC to AC conversion, battery charging, grid bypass and automatic generator start, the Power Tower is a plug and play system like never before. Designed with Off Grid living in mind, the Power Tower offers 6000W continuous power and up to 18,000W of peak power. Coupled with 3500W of Solar MPPT charging capability, the Power Tower ensures you’re never left out in the dark.

 The Power Tower houses all electronics in one, elegant locking glass cabinet. Since all off grid components are housed in one single system, getting up and running is a simple as plugging in the batteries and your solar panels then wiring the output into your breaker panel. With an integrated Automatic Generator Start (AGS), even in the worse case scenarios, a backup generator can automatically be started when the batteries hit a critical level. 

Just because the Power Tower is packed with features does not mean it isn’t reliable. With battery chemistries commonly used mining and industrial applications, the system is robust and safe. A low frequency transformer allows for very high surge capability and more reliable operation.

Power Tower Batteries

A key feature of the Power Tower is the expandable battery system. Every base kit comes with one 3.98kWh lithium battery but can be expanded to up to 7 allowing for almost 28kWh of battery storage. Not only are these batteries expandable but are plug and play right into the Power Tower base. Featuring locking casters, folding handles and mounting tabs, the batteries can be placed wherever best. They feature a built-in screen that displays battery voltage, power consumption, amperage and time left until fully charged or fully discharged.

 The use of LiFePO4 batteries ensures a safe and long-lasting energy storage system that weighs 3 times less and takes up 3 times less space than lead acid batteries. These batteries also protect themselves from over discharge and over charge scenarios and feature a lifespan over 3000 cycles.

Not only do the Power Tower batteries pair perfectly with the Power Tower, but they can also be used with any pre-existing 48VDC system. This battery chemistry is used across all our products and has a proven track record in some of the harshest environments including mining and transit.
