This symbol points out a potential Explosion Hazard.
This symbol points out a potential Fire Hazard.
This symbol points out a potential Electrical Shock Hazard.
These “Safety Alerts” cannot eliminate the hazards that they signal. Strict compliance with these
special instructions, plus common sense are major accident prevention measures.
Study these safety rules carefully before operating or servicing this equipment. Become familiar
with this Owner’s Manual and with the unit. The Unit can operate safely, efficiently and reliably
only if it is properly installed, operated and maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions. The manufacturer cannot anticipate every
possible circumstance that might involve a hazard. The warnings in this manual, and on tags and
decals affixed to the unit are, therefore, not all-inclusive. If using a procedure, work method or
operating technique the manufacturer does not specifically recommend, ensure that it is safe for
personnel. Also make sure the procedure, work method or operating technique utilized does not
render the unit unsafe. Despite the safe design of this unit, operating this equipment imprudently,
neglecting its maintenance or being careless can cause possible injury or death. Permit only
responsible and capable persons to install, operate and maintain this equipment. These units
generate potentially lethal voltages. Ensure steps are taken to make the unit safe before
attempting to work on the unit. The installation of this unit must always comply with applicable
codes, standards, laws and regulations.
General Safety Hazards
For safety reasons, this equipment should only be installed, serviced and repaired by a Service
Dealer or other competent, qualified electrician or installation technician who is familiar with
applicable codes, standards, regulations and product Installation Manual guidelines. The
operator also must comply with all such codes, standards, regulations and product Installation
Manual guidelines.

This unit is designed for INDOOR installation ONLY. Never operate the unit outside without the
proper NEMA enclosure.
Electrical Hazards
All units covered by this manual produce dangerous electrical voltages that can cause fatal
electrical shock. Utility and battery power delivers extremely high and dangerous voltages when
installed, as does the HUMLESS unit when it is in operation. Avoid contact with bare wires,
terminals, connections, etc. while the unit is running. Ensure all appropriate covers, guards and
barriers are in place, secured and/or locked before operating the unit. If work must be done
around an operating unit, stand on an insulated, dry surface to reduce potential shock hazard.
Do not handle any kind of electrical device while standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
To prevent injury, before working on this unit (for inspection, service or maintenance), always put
the unit into the OFF mode.
In case of accident caused by electric shock, immediately shut down the source of electrical
power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT
CONTACT WITH THE VICTIM. Use a non-conducting implement, such as a dry rope or board, to
free the victim from the live conductor. If the victim is unconscious, apply first aid and get
immediate medical help.
Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock.
Fire Hazard
For fire safety, the generator must be installed and maintained properly. Installation MUST
always comply with applicable codes, standards, laws, regulations and product Installation
Manual guidelines. Adhere strictly to local, state, and national electrical and building codes.
Comply with regulations the Occupational Safety and Health Administration (OSHA) has
established. Also, ensure that the unit is installed in accordance with the manufacturer’s
instructions and recommendations. Following proper installation, do nothing that might alter a

safe installation and render the unit in noncompliance with the aforementioned codes, standards,
laws and regulations.
All electrical work must be performed in accordance with local, state and federal electrical codes.
Read all instructions and safety information contained in this manual before installing or using this
product. This product is designed for indoor / compartment installation. It must not be exposed to
rain, snow, moisture or liquids of any type. Use insulated tools to reduce the chance of electrical
shock or accidental short circuits. Always disconnect the energy source prior to installing or
performing maintenance on the system. Live power may be present at more than one point since
our system utilizes both batteries and AC and DC. Always verify proper wiring prior to starting the
unit. There are no user serviceable parts contained in this product.
NOTE Every effort was made to make sure that the information and instructions in this manual were both
accurate and current at the time the manual was written. However, the manufacturer reserves the right to

2.1 How to
The purpose of this document is to outline how to connect multiple solar panels together in
parallel. This is for the optimal use of your 1500 series.
Step 1: Remove the solar panels & carefully set them up next to each other positioned facing the
sun.
Step 2: Look at the back of each solar panel. Each solar panel will have a cord with two (2) x
MC4 connectors on the end of it. Take one (1) of the MC4 connectors from one panel and
connect it to one (1) of the MC4 Y-connectors.
Step 3. Take the other one (1) of the MC4 connectors from the same panel and connect it to one
(1) of the other MC4 Y-connectors.
Step 4: Take the remaining one (1) MC4 connectors from the end of each panel and connect it to
the other MC4 Y-connector.
Step 5: Take the two MC4 Y- connectors and connect them to the MC4 –connectors of your
extension cord (the long cord that has MC4 connectors on one side & Anderson connectors on
the other side).
Step 6. Connect the Anderson connectors from the extension cable into the Humless 1500
Series.
