this Installation Guide for future reference.

WARNING: Limitations on use

The PowerHub 1800 is not intended for use in connection with life support
systems or other medical equipment or devices.

WARNING

To avoid the risk of carbon mo noxide poisoning, generators are not to be used
indoors. When generators are used outdoors there must be sufficient circulation
to vent the carbon monoxide.

1. Before installing and using the PowerHub, read all instructions and
cautionary markings on the PowerHub, the batteries, and in both this
Installation Guide and the Operator’s Guide.

2. The PowerHub is intended for indoor use only. Do not expose the
PowerHub to rain, snow, or spray. To reduce risk of fire hazard, do
not cover or obstruct the ventilation openings. Do not install the
PowerHub in a zero-clearance compartment. Overheating may result.

3. The PowerHub may connect to as many as three source s of DC Power
and one source of AC Power. To reduce the risk of electrical shock,
disconnect all sources of AC and DC power from the PowerHub
before attempting any maintenance or cleaning or working on any
circuits connected to the PowerHub. Turning off controls will not
eliminate this risk.

4. Use only attachments that are intended for use with this product.
Doing otherwise may result in a risk of fire, electric shock, or injury
to persons.

5. To avoid a risk of fire and electric shock, make sure that all of the
installation wiring is in good condition and that wire is not
undersized. Do not operate the PowerHub with damaged or
substandard wiring.

6. Do not operate the PowerHub if it has received a sharp blow, been
dropped, or otherwise damaged in any way. If the PowerHub is
damaged, see the Warranty section.

Precautions When Working With Batteries

WARNING: Fire or Explosion Hazard

1. Use only SEALED batteries with the PowerHub 1800.

2. Follow all instructions published by the battery manufacturer.

3. Working in the vicinity of batteries may be dangerous. Unsealed

batteries can generate explosive gases during normal operation.
Therefore, you must read this guide and follow the instructions
exactly before installing or using the PowerHub.

4. This equipment contains components which tend to produce arcs or

sparks. To prevent fire or explosion, do not install the PowerHub in
locations that require ignition-protected equipment. This includes any
space containing gasoline-powered machinery, fuel tanks, as well as
joints, fittings, or other connections between components of the fuel
system.

5. To reduce the risk of battery explosion, follow these instructions and

those published by the battery manufacturer.

6. Make sure that nothing is blocking the air vents on the back of the

enclosure.

7. Never smoke or allow a spark or flame near the batteries.

Safety

8. Use caution to reduce the risk of dropping a metal tool on the

batteries. It could spark or short circuit the battery or other electrical
parts and could cause an explosion.

9. Remove all personal metal items, like rings, bracelets, and watches

when working with batteries. Batteries can produce a short circuit
current high enough to weld metal, causing a severe burn.

10. Have someone within range of your voice or close enough to come to

your aid when you work near a battery.

11. Wear complete eye protection and clothing protection. Avoid

touching your eyes while working near batteries.

12. Have plenty of fresh water and soap nearby in case battery acid

contacts skin, clothing, or eyes.

Safety

13. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.

Precautions for Using Rechargeable Appliances

CAUTION: Equipment Damage

This equipment produces a modified sine wave output. Equipment damage may
occur if the rechargeable appliance is not designed to use modified sine wave
output. If you are unsure about using your rechargeable appliance with the
modified sine wave, contact the equipment manufacturer.

Most rechargeable battery-operated equipment uses a separate charger or
transformer that is plugged into an AC receptacle and produces a low
voltage charging output.

Some chargers for small rechargeable batteries can be damaged if
connected to the PowerHub. Do not use the following with the PowerHub:

• Small battery-operated appliances like flashlights, razors, and night
lights that can be plugged directly into an AC receptacle to recharge.

• Some chargers for battery packs used in power hand tools. These
affected chargers display a warning label stating that dangerous
voltages are present at the battery terminals.

Purpose The PowerHub 1800 is intended to be an entry-level inverter system for

use in support of AC loads up to1440 W continuous, (1800 W on a
5-minute surge). It can be used as a stand-alone power source (softwired)
or be permanently installed on site (hardwired). It is not intended to be
used as an uninterruptible power source (UPS).

Function The PowerHub 1800 is specifically designed to use power stored in two

battery boxes that hold up to four 12 Vdc sealed, lead-acid batteries (not
provided) to power AC loads and to recharge those batteries when an A C
source (generator or utility grid) is available. Run-time on batteries will
vary depending on the size of the loads using the po wer.

Inverter
Features

It can also use renewable energy, such as 12 V solar panels and small
12 V wind turbines, to recharge the batteries. Using renewable energy
sources require a permanent “hardwired” installation and will require
additional equipment and structural enhancement to be code-compliant.

The inverter consists of the following user features:

• Inverter Control Panel

• Four 120 Vac outlets on the front panel.

• One supplementary protector to protect the 120 Vac outlets from
overload.

• Two Battery Box Connection Ports (one on each side)

PowerHub 1800 Features

The inverter has the following input/output terminals:

• Two DC Anderson ports for 12 V battery connections from the
Battery Box; one on each side.

• Two pairs of DC input terminals for renewable energy connections:
one 32 A input terminal and one 80 A input terminal. External inputs
to these terminals must be externally regulated. Solar panels must
use charge controllers and wind turbines must be self-regulated.

• The 32 A terminals can be used for 12 Vdc input up to

400 W maximum.

• The 80 A terminals can be used for 12 Vdc input up to

1000 W maximum.

• AC input terminal (for grid or generator input)

• AC output terminal (for AC output in hardwired installations)
