SHOCK HAZARD:
Possible shock or death if used improperly, when
damaged or used by untrained personnel.
FLAMMABLE HAZARD:
Lithium ion batteries contain ammable liquid
electrolyte that may vent, ignite and produce
sparks when subjected to high temperatures
(> 150 °C (302 °F)), when damaged or abused
(e.g., mechanical damage or electrical overcharge).
Burning cells can ignite other batteries in close
proximity.
Vapors or mists from a ruptured battery may cause
respiratory irritation.

13Power Tower Battery 3.9 - User manual - English
The initial integration of the battery system with your inverter, charger or load is crucial to proper
operation. DO NOT mix the Power Tower Battery with any other type of battery including other
lithium, LiFePO4, SLA, GEL or ooded batteries.
NEVER plug the Power Tower Batteries in series.
4.1. Initial Commissioning
4.1.1. Initial Commissioning
If only a single Power Tower Battery is used, then no balancing or voltage check is required.
1 - Turn ON the battery master switch to ensure no errors are present 2 - Turn OFF master switch
3 - Connect Positive wire rst
4 - Connect Negative wire
5 - Turn Master Switch ON
6 - Turn ON load
If the battery does not output any voltage after turning on the load (inverter or other), this may
be a result of a rapid capacitor charging inside the load that may be tripping the battery’s
internal safety mechanism. This can be overcome by connecting a second battery in parallel to
share the spike or use a pre-charge resistor.
4.1.1.1. Pre-Charge Resistors (when using 3rd party inverter)
Certain inverters and capacitive loads may have an in rush of over 1000A on startup
which may trip the internal safety cut off of the battery. To charge these capacitors and
still maintain the safety prole of the battery, a pre-charge resistor can be used during
commissioning. Please review the information in the following resource to match the
capacitance of your load (contact inverter manufacturer):
http://liionbms.com/php/precharge.php. A
100-250W resistor with a 20-50 ohm rating is recommended. Contact HPS or your local solar
installer or electrician for assistance.
4.1.2. Multiple Battery Commissioning
4.1.2.1. Connecting to Power Tower
The Power Tower inverter system is designed for an easy plug and play commissioning. All
parallel connections are made internally when plugging in to the positive and
negative terminals.
NO external connections between batteries are required.
Before connecting batteries, turn ON all batteries and ensure that each voltage is within
0.1V of each other or as close as possible. Unbalanced batteries will eventually rebalance but
performance may be limited until all batteries are balanced.
HPS recommends balancing all batteries no matter of the voltage if possible.

14 Power Tower Battery 3.9 - User manual - English
Example of batteries that are ready to plug but balancing is still recommended:
Example of batteries that require balancing:
Batt #1:
53.2V
Batt #1:
53.2V
Batt #2:
53.2V
Batt #2:
52.8V
Batt #3:
53.2V
Batt #3:
53.2V
4.1.2.1.1. If balancing is not required:
1.Turn OFF all batteries and Power Tower
2.Connect all Positive terminals to Power Tower
3.Connect all Negative terminals to Power Tower
4.Turn ON Batt #1 followed by Batt #2
5.Wait until both batteries equalize. A battery that has a higher state of charge (SOC) will
charge the other until stable and will show up on the battery screen as CHRG on one
battery and DSCH on the other. Wait until the amperage transfer between batteries is less
than 1A before proceeding.
6.Turn ON Batt #3 and repeat step and 6 until all batteries are connected.
7. Turn ON Power Tower

15Power Tower Battery 3.9 - User manual - English
4.1.2.1.2. If balancing is required:
1.Turn OFF all batteries and Power Tower
2.Connect Positive terminal of Battery #1
3.Connect Negative terminal of Battery #1
4.Turn ON Battery #1
5.Turn ON Power Tower
6.Turn OFF any load to the Power Tower (AC Circuit Breaker)
7. Charge until Battery #1 is full
8.Turn OFF Power Tower followed by Battery #1
9.Set aside Battery #1 for a minimum of 1 hour in OFF position to settle voltage
10. Repeat steps 1-9 for all batteries
11. Check all voltages to ensure they are balanced, then proceed to section 4.1.2.1.1
It is preferred that the charging process for this step be accomplished using grid power or
generators for a more consistent charging process but may be accomplished using solar.
4.1.2.2. Connecting to 3rd party inverters or loads
Recommended Wire Gauge: dependent on total amperage draw. See local authority amperage
chart.
Lug Hole Diameter: 7/16” to ½”
Before connecting batteries, turn ON all batteries and ensure that each voltage is within 0.1V
(100mv) of each other.
If balancing is required, see section 4.1.2.1.2
Multiple batteries should only be used in parallel and never plugged in series. Parallel
connections can be made either at the terminal or using a bus.
Terminal Connection: Connect all positive terminals then all negative terminals with one
positive and negative lead connected to load. This is typically accomplished using bus bars or
short wire leads
Bus Connection: Connect the positive and negative terminals to their own respective busses.
In this conguration, all wire lengths from battery terminal to bus must be identical in length.

16 Power Tower Battery 3.9 - User manual - English
1.Ensure all batteries are OFF and disconnected from load
2.Connect all batteries in parallel
3.Turn on Battery #1 and #2 and let batteries equalize by waiting until amperage transfer
between batteries is less than 1A.
4.Turn ON Battery #3 and repeat steps 3-4 for all batteries
5.Connect to load
6.Turn load ON
4.2. Grounding
Ensure that the battery’s metal enclosure is ground to earth in a grounded system or the battery
negative terminal when operating a oating system. A grounding point is provided and indicated as
shown in the following image.
4.3. Seasonal or Long Term Storage
If seasonal shut down is required, please follow the below steps:
1.Fully charge battery
2.Turn OFF load and charger
3.Turn OFF batteries
4.Store batteries in location that does not fall outside specications including in areas where
temperatures could fall below -20 °C
Periodically check battery voltage by turning batteries ON with no load connected. Ensure voltage
is above 50V. If below, batteries should be recharged.

The system should always be left in the OFF position when not in use. In the ON position, very
little power is consumed but it will affect future run times and may deplete the system over time.
HPS recommends always turning the battery off when not in use.
When using the system in cold temperatures (below 0 degrees Celsius), discharge power may be
limited and run time can be affected by up to 40%. The product will naturally warm itself with
usage and improve capabilities. For maximum capacity and performance, ensure the battery is
stored at room temperature (20 degrees Celsius).
5.2. Recharging Guide and Storage
Charge a minimum of once every 3 month to ensure the energy level does not fall to damaging
levels. If this is not possible, periodically check that the voltage is above 50V (25V for 24V version).
Never charge above 75A. To achieve advertised life cycle, each battery pack should only be charged
at 20A.
Ensure to follow integration programing guidelines if using this battery with anything other than a
Power Tower.
