This is the Power Tower Battery by HPS. A state-of-the-art battery module for your off-grid, or back-up energy system. This pack uses lithium-iron phosphate chemistry for maximum reliability in deep-cycle and solar applications, and integrates easily with any battery-based inverter that offers either lithium or AGM voltage settings. Expand your Power Tower system capacity, or use in your own DIY system design.
Expandable & Intelligent…
Up to 15 batteries can be wired in parallel, allowing for almost 60 kWh of usable energy.
A built-in screen displays battery voltage, power consumption, input/output current, and time left until fully charged or fully discharged.
Lithium Ion has a proven track record in some of the harshest environments including mining and transit.
A 300A fuse (CSA rated) is included for individual disconnect.
LiFePO4 batteries are fume-free, allowing you to place the system anywhere indoors.
Over-voltage & under-voltage protections are built-in
With locking rolling casters, folding handles and mounting tabs, the batteries can be moved and installed with ease.
How to use the Power Tower Battery…
LFP battery units can be installed in place of any standard AGM lead-acid, and will provide twice the capacity in half the space and weight. Because each battery unit is already at 48V, your need for bulky battery interconnects disappears. Place them in your battery compartment, connect each to a common terminal point, then from there to your inverter and charging equipment.
While AGM setpoints will work fine, we will provide data for programming your inverter & charging setpoints specifically for LFP.
Keep the following in mind when designing your system…
- Keep the batteries at room temperature for optimal performance
- Operate the batteries in the 30-100% state-of-charge range for the longest cycle life
- Connect each battery in parallel with the same wire leads to the common terminal connection – cell balancing is most accurate when all wire resistances are identical.
