1 INTRODUCTION
The VertaMax Power Inverter is a highly reliable product that uses advanced technologies for high
performance and stability. The VertaMax efficiently converts DC power from your vehicle, boat, or directly
from a dedicated 12V DC battery, into 120V AC power that is commonly used in a wide variety of household
AC items, such as computers, mobile phone chargers, radio, TV etc.
The VertaMax works in two stages: During the first stage, the DC to DC converter increases the DC input
voltage from the power source (e.g. 12V battery) to 300VDC. In the second stage, this high voltage DC is
converted into a modified sine wave AC output using advanced power MOSFET transistors or IGBT
technology in a full bridge configuration. The result is excellent overload protection and capacity to operate
different reactive loads.
The Inverter may be used for many different applications including Solar (PV) battery systems, Wind Turbine
battery systems, Recreational Vehicles, Boats, etc.
Please read this manual carefully before installing or using the inverter and keep it for future reference.

2.1 ELECTROSTATIC (ESD) PRECAUTIONS
All electronic circuits may be damaged by static electricity. To minimize the likelihood of electrostatic
damage, discharge yourself by touching an electrical ground (e.g.: copper pipe) prior to handling the unit and
avoid touching components on the circuit boards. The risk of electrostatic damage is highest when relative
humidity is below 40%.
2.2 MOUNTING
Mounting is optional for the VertaMax; however, the environment must be dry and protected from water.
1. The VertaMax can be mounted on a vertical or horizontal surface. If mounted vertically, the unit
should be oriented such that neither end is at the top so foreign material cannot settle into the
unit.
2. Install four user-supplied fasteners through the four inverter mounting slots and into the
mounting surface.
3. Tighten all the fasteners to ensure the inverter cannot slide in any direction.
WARNING: Do not mount on flammable surface material.
2.3 GROUNDING
The VertaMax is designed to work with grounded electrical systems. In the inverter, ground is not connected
to the input terminals.
Use a copper wire to connect the grounding terminal on the VertaMax enclosure to earth ground or chassis
ground. The grounding terminal is located on the AC Output end of the inverter.
Do not connect the system negative conductor to this terminal. NEC requires the use of an external ground
fault protection device (GFPD). The system electrical negative should be bonded through a GFPD to earth
ground at one (and only one) location. The grounding point may be located in the solar/wind circuit or the
battery circuit.
2.4 CONNECTIONS
WARNING: Electrical installations must meet local and national wiring codes, and should be performed by a
qualified electrician.
WARNING: Do not connect the inverter and another AC source (such as a generator or utility power) to the
AC wiring at the same time.
WARNING: Do not connect the inverter to an AC branch circuit that has high-power consumption loads. It
will not operate electrical appliances that consume more than the units rated watts.
WARNING: Loose connectors result in excessive voltage drop and may cause over heated wires and melted
insulation, which can lead to electrical fires.
WARNING: Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and
may permanently damage the Inverter.
IMPORTANT: The NEC requires that the wires carrying the system current never exceed 80% of the
conductor’s current rating (sizing recommendations are located in Section 4).
IMPORTANT: In addition to the protection provided by the Inverter’s internal fuses, NEC requires a UL-listed
fuse in the battery’s positive DC cable as close to the battery as possible (sizing recommendations are
located in Section 4).
1) The VertaMax has four DC terminals (two positive and two negative) to share the load. Both positive
terminals are internally bonded and both negative terminals are also internally bonded. The four cables
used for these terminals should be of equal length.
windynation Page 5 of 16

VertaMax User Manual
Revision 1.1
IMPORTANT: For 1500 Watt units, use a minimum of 6 AWG wire with a wire length not to exceed 6 feet*;
using all four battery posts on the inverter.
IMPORTANT: For 2500 Watt units, use a minimum of 2 AWG wire with a wire length not to exceed 6 feet*;
using all four battery posts on the inverter.
* For wire runs longer than 6 feet, consult a Wire Gauge Chart to safely determine what gauge of wire will be
needed.
2) Prepare Cables to connect the power source to the inverter (not included). The cables should be as short
and thick as possible to reduce the voltage drop between the power source and the inverter as it draws
current from the power source.
a) Inverter end of the cable: Terminate copper wire with a 0.330” diameter, tin-plated copper lug. It is
recommended to cover the lug barrel with 1 inch of heat shrink tubing.
b) Power Source end of the cable: Terminated with a lug or other connector that provides a secure, low
resistance connection. For example, if the power source is a battery, the cable must be terminated
with a battery terminal that clamps to the post on the battery.
IMPORTANT: If there is an excessive voltage drop and the voltage at the inverter drops below 10 volts,
the inverter will shut down.
3) Wire the positive cable(s) through user-supplied UL-listed fuse (e.g. Buss Fuse ANL-250 or equivalent)
as shown below. The fuse should be as close to the battery as possible. The specific fuse ampere rating
should be sized to allow operation of all your DC powered equipment but cannot exceed the maximum
current (amp) rating of the inverter by more than 40%.
4) Be sure the inverter power button is in the ‘OFF’ position and the DC Power source is also off.
5) Connect the cable end with the 0.330” lug to the Power Input Terminals on the DC Input end of the
inverter as shown below. The red terminal is positive (+) and the black terminal is negative (-).
Use M8 Washers (provided) as needed to ensure the threaded end cap is fully tightened and the Cable
Lug is secured.
IMPORTANT: When fully tightened, the Cable Lug should not be able to rotate around the Inverter
connection post. Check and tighten the end caps periodically as they can become loose from vibrations
or thermal cycling.

Revision 1.0
6) Connect cables to the power source:
a) Connect the cable from the Negative (Black) Terminal(s) of inverter to the Negative Terminal of the
power source; ensure a secure connection.
b) Connect the cable from the Positive (Red) Terminal(s) of the inverter to the Positive Terminal of the
power source (the battery’s main fuse or the battery selector switch, if you are using one) ; ensure a
secure connection.
WARNING:If you are making a permanent AC connection to the inverter, make sure that the AC wiring is
performed before any DC wiring is done. (DC hook-up may energize internal components and create an
electrical shock hazard).
3 OPERATION
3.1 POWER
The VertaMax features a Soft Start to handle the power surge that is created when some appliances are
turned on. This feature helps protect both the appliance and the inverter from excessive power draws and
surges.
When the power switch is turned on, the VertaMax Soft Start will smoothly bring up the AC power. The Soft
Start circuitry also activates under excessive loads and short circuits, to quickly turn off power to protect the
device and the inverter. Soft Start will attempt to smoothly bring up the AC power, unless it detects an
excessive load.
3.1.1 Power ON
Ensure the VertaMax is properly installed and connected as shown in Section 2 and ensure the DC Power
Source is ON (if switched).
From the AC Output end of the inverter, switch the rocker power switch up to the ON position. The green
power indicator will light and the VertaMax will now deliver AC power to the outlet(s) on the AC Output end of
the inverter.
Plug the AC product(s) you wish to operate into the AC outlet(s) and switch them on, one at a time.
windynation Page 7 of 16

VertaMax User Manual
Revision 1.1
IMPORTANT: Do not turn on all AC products at the same time and turn on the larger power product first.
IMPORTANT: In the ON position, even if no loads are connected, there is a low current draw (<600mA).
3.1.2 Power OFF
From the AC Output end of the inverter, switch the rocker power switch down to the OFF position to shut
down the Inverter completely, preventing it from drawing power from the batteries. The green power indicator
will go out.
This will also “reset” the unit if it shuts down due to low battery or overload.
3.1.3 Remote ON/OFF
The VertaMax comes supplied with a remote control that will allow you to turn the power inverter ON or OFF
from a remote location when the inverter is installed in an out of reach location.
To remotely control the power function of the inverter, switch the rocker power switch down to the OFF
position, essentially shutting down the Inverter. From the Remote Control press the “ON” button to turn the
inverter on and the “OFF” button to turn the power off.
IMPORTANT: Although the main power rocker switch will be in the OFF position, the green power indicator
will work as normal operation and will light when the VertaMax is remotely “ON”.
3.2 USB PORT
The USB outlet, if equipped, will supply 5 volts at 500ma to charge and power cell phones, MP3 Players, and
other small electronics. It will NOT transmit or receive any data and is only used to supply power to a USB
powered device.
IMPORTANT: Although the USB port may be present on all models, it may not be wired and equipped for
use. In these cases, a cover will be present on the port and should NOT be removed for use.
3.3 METER READINGS
The VertaMax is equipped with a digital meter on the AC Output End of the unit. The meter will cycle through
three Input and Output values in three-second intervals as follows:
1) AC LOAD VOLTAGE: The voltage of the AC OUTPUT; shown in Volts AC
2) AC POWER: The output power; shown in Watts
3) DC BATTERY VOLTAGE: The voltage of the DC INPUT; shown in Volts DC
3.4 PROTECTION –ALARMS
The VertaMax has several protection features to protect itself as well as your electrical system.
3.4.1 Over Input Voltage
When the 12V DC INPUT power voltage exceeds 16V DC, the inverter will automatically shut down.
IMPORTANT: Although the inverter incorporates fused protection against over-voltage, it is still possible to
damage the unit when the input voltage exceeds 16V DC.

VertaMax User Manual
Revision 1.0
3.4.2 Low Input Voltage
As a battery is used, its voltage begins to decrease. When the inverter senses that the voltage at its DC input
has dropped to 11V ± 0.3 DC, an audible alarm sounds and the red FAULT indicator will light. When this
happens, it is important to remove or shut down computers or other sensitive devices that may be connected
to the VertaMax and recharge the battery before its capacity drops too low. The inverter can operate while
the battery is recharging.
When the input voltage rises to approximately 11.3 – 11.9V DC, the inverter restores to normal operation and
the red FAULT indicator will turn off.
If the audible alarm is ignored, the inverter will automatically shut down when the voltage drops to the range
of 9.8 - 10.2V DC. This protects the battery from being over-discharged.
3.4.3 Power Overload
When the starting power exceeds the rated surge power or the AC appliances connected to the VertaMax
exceed the inverters power rating, the inverter will automatically shut down and the red FAULT indicator will
light.
When in over current protection mode, the inverter cannot automatically restore to normal operation; reset to
normal operation by using the manual power switch.
3.4.4 Over Heating
When the inverter exceeds a safe operating temperature, due to insufficient ventilation or an increase of
ambient temperature, the inverter will automatically shut down, an audible alarm sounds and the red FAULT
indicator will light.
When the internal temperature drops below the surrounding air temperature, the inverter will automatically
return to normal operation.
Important: The cooling fan is designed to operate when the temperature increases but may not be adequate
enough to prevent overheating.
3.4.5 Short Circuit
This inverter is equipped with multiple internal fuses. When in a short circuit state, the inverter will
automatically shut down.
Important: Please see Section 5 Troubleshooting and Support for Fuse replacement instructions

4 APPLICATION
4.1 POWER CONSUMPTION
For each piece of equipment you will be operating from the inverter, you must determine the battery’s
reserve capacity (how long the battery can deliver a specific amount of current – in automotive batteries,
windynation Page 9 of 16

VertaMax User Manual
Revision 1.1
usually 25 ampere) or ampere-hour capacity (a measure of how many amperes a battery can deliver for a
specified length of time).
Example – Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25 ampere for 180
minutes before it is completely discharged.
Example – Ampere-hour capacity: a battery with an ampere-hour capacity of 100 ampere-hours can deliver
5 ampere for 20 hours before it is completely discharged.
To determine the battery ampere-hour capacity:
1) Determine how many watts each piece of AC equipment (TV, light bulbs, etc) consumes. This can
normally be found on the product label. If only the current draw is given, multiply the current draw by
115 to get the watt consumption.
2) Estimate the time (in hours) that each piece of equipment will be running between battery charging
cycles.
3) Calculate the total watt-hours of energy consumption (power in Watts x operating time in hours)
using the average power consumption and the total estimated running time (in hours). Power x
Operating Time = Watt-Hours.
4) Divide the watt-hours by 10 to determine how many battery (12 volt) ampere-hours will be
consumed.
