Before using the unit, read all instructions and cautionary markings on:
1. The Power Tower unit
2. The Power Tower Batteries
3. All appropriate sections of this manual
CAUTION - To reduce risk of injury, charge only HPS Power Tower rechargeable batteries. Other
types of batteries may rupture, causing personal injury and damage.
DO NOT expose the unit to rain, snow or liquids of any type. The unit is designed for indoor use
only.
DO NOT disassemble the unit. Take it to a qualied service center when service or repair is required.
Incorrect re-assembly may result in a risk of electric shock or re.
To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or
cleaning. Simply turning off the unit without disconnecting wiring will not reduce this risk.
CAUTION - Batteries and Inverters may only be installed by a qualied professional (e.g. solar
installer). If you have any questions, please contact HPS.
NEVER charge a frozen battery.
USE CAUTION when working with metal tools on or around batteries. The potential exists to drop a
tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an
explosion.
Turn OFF Power Tower battery switch and disconnect all wiring before installation or while
performing repairs or maintenance.
When the PV module or panel is exposed to light, it starts to supply high voltage DC power. Be sure
to turn off the DC Breaker switch before commencing maintenance, and make sure the cables from
the PV panel are properly sealed after disconnection.
GROUNDING INSTRUCTIONS - The Power Tower should be connected to a grounded permanent
wiring system. For most installations, the Ground Lug should be bonded to the grounding system at
one (and only one point) in the system. All installations should comply with all national and local
codes and ordinances.
AVOID AC output short-circuit, DC input short-circuit and DO NOT connect the mains while DC input
short-circuit

Note: Appliances like Air conditioners need at least 3 minutes to restart during a power outage.
These systems bounce on and off (time is required to balance the refrigerant gas inside the circuit);
so in order to protect your Air conditioner, please consult the Air conditioner manufacturer whether
they have already provided a time delay function before installing. Otherwise, the Power Tower may
trigger an overload fault and shut off its output to protect your appliance. This protection may not
always be sufcient and may cause permanent damage to the Air Conditioner.
3.3. Batteries & Cabling
The Power Tower is designed to work exclusively with the Power Tower Batteries (48V version) and
should not be used with any other batteries. All cabling provided should not be cut or trimmed as
this will create an imbalance in resistance throughout the cabling and cause performance issues.
Up to 5 batteries: Five batteries can be connected directly to the Power Tower without any
additional cabling. Ensure you follow the commissioning process dened in the Power Tower
Battery manual.
6 - 15 batteries: When connecting 6 or more batteries, please use jumper leads sold through
HPS or construct similar jumper leads that are identical to one another in length. Reuse the end
connectors to ensure the leads from the battery bank to the inverter are identical.
See schematic below.

(REUSE PROVIDED CABLING)
3.4. AC Connections
Installation should be done by a qualied electrician. Consult local code for the proper wire sizes,
connectors, and conduit requirements.
At the bottom of the Power Tower enclosure is a 3m (10’) AC output cable which should be wired to
your breaker panel. The National Electrical Code requires an external breaker switch.

14 Power Tower - User manual - English
AC Output Wiring Instructions:
Step 1: Disconnect the unit from the battery by removing the battery cables. Turn the Power Tower
OFF before disconnecting the batteries. Disconnect any inputs if present. Turn off main
output breaker on the inside of the cabinet.
Step 2 (120V Version): Connect the GND (green/yellow), Line (black), and neutral (white) wires from
the AC output to the proper circuit breaker panel with the panel OFF.
Step 2 (120V/240V Version): Connect the GND (green/yellow), Line 1 (black), Line 2 (typically red)
and neutral (white) wires from the AC output to the proper circuit breaker panel with the
panel OFF.
Maximum Power When using split phase conguration:
• L1 to N = Max 3000W (120V)
• L2 to N = Max 3000W (120V)
or
• L1 to L2 to N = Max 6000W (240V)
or
• L1 To L2 = Max 3000W (240V)
• L1 to N = Max 1500W (120V)
AC Generator/Grid Input Wiring Instructions:
For easy installation and compatibility, the Power Tower has been outtted with two (2) L14-30
receptacles. These receptacles match the most common generator plug type (120/240V) plugs. A
simple extension cord between both will enable quick installation. Ensure all local electrical codes
are met when wiring the input. ALWAYS ENSURE THAT BOTH INPUT PLUGS ARE FED BY THE SAME
SOURCE. The inputs must use the same wave form and sinusoidal timing, therefore a single source
must be used. For example, a single generator must be used NEVER two (2) different generators
unless they have synchronization capability. When powering from the grid, two separate circuits
can be used as both wave forms should be identical but both inputs should use the same L-N. Do
not split a 240V output into two (2) 120V lines and input into two (2) separate plugs.
A 120V Power Tower will not accept an incoming 240V input as it draws from a single hot lead of
the L14-30 receptacle. The 120V/240V version will accept only 240V input as it will pull power
from both hot leads.
AC Input Wiring Instructions:
Step 1: Ensure generator or input grid power is off.
Step 2: Connect input source to Power Tower using one (1) or both input plugs. A L14-30P can be
purchased from a local electrical supplier or a complete compatible extension cord
can be used.

15Power Tower - User manual - English
Step 3: Wire the L14-30P based on the following:
120V Model:
• Connect L1 to X
• Connect N to W
• Connect Ground to G
Always ensure the voltage measured between X and W is 120V.
120V/240V Model:
• Connect L1 to X
• Connect L2 to Y
• Connect N to W
• Connect Ground to G
Always ensure the voltage measured between X and Y is 240V.
Step 4: Turn on generator or grid power.
BOTH PLUGS MUST BE FED BY SAME SOURCE AND PHASE
Each plug has a 30A breaker to ensure no more than 30A is drawn per plug. Ensure that the phases
are matching.
Single 120V 30A Input:
When charging the Power Tower system using only a single 120V 30A input, ensure that the
charging rate and power drawn from the load (home) is less than 30A.
3.5 Automatic Generator Start (AGS)
The two-wire connection that is provided with the Power Tower allows for automation of a backup
generator when solar power is insufcient. The two-wire system closes a relay when a low voltage
scenario is detected and opens when the batteries have reached a higher voltage.
AGS relay ON: 51Vdc
AGS relay OFF: 54.6Vdc

GROUNDING & SOLAR WIRING SECTION 4

17Power Tower - User manual - English
Grounding of the Power Tower should reect local electrical codes and installation location and
application requirements. The following should be used as a general rule but should be conrmed
by local electrical codes.
4.1. Grounding
4.1.1. When Earth Ground is Available
When a proper ground to earth is available, the Power Tower grounding point should be tied to
earth. In this installation, the neutral (white) should be separate from the ground (green) wire.
4.1.2. When No Earth Ground is Available
Ground and neutral wire should be bound and should be connected to the negative battery
bus. To do so, connect the grounding point on the Power Tower to the negative terminal of the
battery. Connect the output neutral AC wire to the grounding point or the negative terminal. The
resulting circuit should be equivalent to the following. A separate GFCI will need to be installed
on the output in the circuit breaker panel.
4.2. Solar Wiring
The Power Tower is congured for use with a plug-and-play solar panel.
Maximum input Amperage: 30A per input, 60A total
Maximum Open Solar Panel Voltage: 150Vdc
Maximum Solar Power: 3500W
Solar Connectors: MC4

4.2.1. Adding Additional Solar or Wind Power
If the provided solar power is insufcient, additional solar charging or wind charging capability
may be added directly to the batteries. Chargers may be connected directly to the battery
terminals or preferably, through an available DC input port below the Power Tower. When
doing so, respect all parameters listed in the Power Tower Battery manual and all solar or wind
charger installation requirements. Ensure that the total charging amperage does not exceed the
maximum allowable charging amperage for the battery. For example, a system with three (3)
Power Tower Batteries has a recommended charge amperage of 20A and maximum charge of
75A per battery for a total of 60A recommended and 225A maximum. The Power Tower charging
off of the grid and/or maximum solar will output 60A therefore additional charging from an
external source is possible but not recommended for maximum battery cycle life. Systems with
more batteries are well suited for additional solar chargers or wind turbines.

SYSTEM CONFIGURATION SECTION 5

20 Power Tower - User manual - English
5.1. AC Charge Rate (setting 4 + 5)
The default programming is set to 20A AC charging which will prolong the life of the battery but
may not be appropriate for all users. If more than one battery is connected, then a higher charging
amperage is acceptable and desired as each battery will split the available amperage. For example,
two (2) batteries connected with the Power Tower set a 20A charge rate will receive 10A each. It is
also possible to increase the charging amperage to favor fast charging over a long life.
5.2. Off Grid vs Hybrid Mode: Power Priority (setting 6 + 7)
The default programming for the Power Tower is best set for an off grid situation and is set to
AC Priority Mode. This setting uses AC input power if available at all times instead of depleting
batteries. This ensures that when the automatic generator starter turns on the generator, power
from the generator will be used to power both the output (your home) as well as charge the
battery. Please ensure that the generator has the necessary power for both house loads and battery
charging.
If a power source such as grid or generator is always available but solar and battery should be
prioritized over this generator/grid power source, the inverter should be set to Intelligent mode.
This mode will deplete the battery rst then engage the AC input mode when voltage falls below
49.6Vdc. This voltage switch over can be changed by changing setting number 7 (DC Voltage Point).
The voltage transition point selected (2.9, 3.0 or 3.1Vdc) dictates the transition point by multiplying
this value by 16. For example, the default 3.1Vdc mode is 3.1 x 16 = 49.6Vdc.
