Size a Battery Bank
Battery types and capacity relate to the overall inverter performance. To size a prope r battery
bank, you need to identify the loads that you will be utilizing, as well as an estimate duration
(hours/day) you will be using the load. The inverter is only compatible with 24V battery banks, and
oversizing should be considered due to e#ciency losses.
1.
Determine Your Watts (Amps x Volts)
Every electronic will have a sticker or plate identifying the watts directly (W) or will sho w you
the voltage value (V) as well as amperage (A) which need to be multiplied to get Watts. T he
formula is below:
Watts (W) = Volts (V) x Amps (A)
Example: Fan Watts = 120V ∗ 0.4A = 48Watts
2.
Estimate Load Run-Time in Watt-Hours (Wh)
Estimate how many hours per day you will be using the load and multiply this by your Watts
per load.
Example: Fan Watts x 12 hours = Watt-Hour (Wh)
48W x 12h = 576Wh
Determine Battery Capacity in Amp-Hour (Ah)
Divide your Load Run Watt-Hour result by the battery voltage.
Load Run-Time (Wh)/Battery Voltage (V) = Amp-Hour (Ah)
Use 24V, supported voltage of the inverter as a reference.
576Wh/24V = 24 Ah
Oversize the Battery
The calculated Amp-Hour value represents the minimum size battery capacity to run your
load for your intended time. Note that this assumes 100% use of a battery, which is not
recommended. Assuming 50% depth of discharge, you want to multiply this value by 2 and
you also want to multiply by 1.25 to account for some e#ciency losses.
Formula:
24Ah x Oversize x Efficiency Losses = Recommended Amp-Hour
0
Therefore, a 60Ah battery bank, or close, will be able to support a 12-hour run time while
also prolonging battery life for the best system size possible.
You will need a battery charging source as this is a non-charging inverter and will only work
to deplete the battery.
Actual battery quantities vary by battery capacity and rates of discharge.

Step 2. Plan a Mounting Site
Follow the guidelines below:
Cool, dry, well-ventilated area
The inverter must be installed in a site where the fans are not blocked or where they a re not
hit directly by the sun. The site should be free of any kind of moisture with a clearance of a t
least 10 inches around the inverter for adequate ventilation.
Protection against fire hazard
The inverter should be away from any flammable material, liquids, or any other combustible
material.
Close proximity to battery bank
Put the inverter close to batteries banks to prevent excessive voltage drop. Choose a p roper
sized wire going from the battery bank to the inverter.
Limiting electromagnetic interference (EMI)
Ensure the inverter is firmly grounded to a building or vehicle. Alternatively, it can be earth
grounded. Keep the inverter away from EMI receptors such as TVs, radios, and othe r audio/
visual electronics to prevent damage/interference.
Secure mounting
The inverter should be stand-alone or mounted by using the outlying terminals with M4 and
M6 screws on the inverter.
KEEP DRY FRAGILE VENTILATION
-4°F to 131°F / -20°C to 55°C
Do not over-torque or overtighten the terminals. This could potentially damage th e unit.
Refer to the technical specifications for maximum wire sizes on the controller and for the
maximum amperage going through wires.
Ensure the inverter is in the OFF position before connecting to anything.
Do not install the inverter in the same compartment as the battery bank because it could
serve as a potential fire hazard.
Never mount the inverter vertically on a vertical surface since it would present a hazard for
the fan opening, undermining cooling the inverter.
-9-
Step 3. Ground
If available, the chassis ground lug should be connected to a ground point such as a vehicle
chassis or boat grounding system. In fixed locations, connect the ground lug to earth ground. The
connections to ground must be tight and against bare metal. Grounding is highly recommended
for both when using the inverter in a mobile application, such as an RV, or in a building.

Step 4. DC Wiring
Be careful of the positive and negative poles. Reversing the poles might cause permanent
damage to the inverter and will void the warranty.
For your safety, it is recommended to use a 150A battery fuse.
The inverter is suitable for 24V battery bank systems ONLY. Not following the minimum DC
requirement will cause irreversible damage to the device.
The input terminals of the inverters are embedded with large capacitors. The input circuit
is completed once the terminals are connected to both positive and negative wires. This
commences drawing a heavy current momentarily. As a result, there may be a sparking
occurring even if the inverter is in the o! position. To minimize sparking, it is recommended
that you should choose an appropriate sized wire feeding into the inverters and/or install
an external fuse leading into the inverter.
Step 1:

Operations on Inverter
After proper battery and AC load connections, you can operate the inverter.
1. On the AC side, rock the ON/OFF Switch to the ON position.
2. The inverter is operating normally.
When finishing using the inverter, power o! the AC loads first, and then rock the ON/OF F Switch
to the OFF position.

When the inverter turns on, it is normal to see the fans run for a second and hear a beep.
Avoid powering on the inverter with the load (electronic devices) already switched on. This
may trigger an overload since some electronic devices have an initial high power surge to
start.
When switching o! the inverter, turn o! the electronic devices first. Although the inverter
is o!, the terminal capacitors will still have a charge, so the DC and AC terminals must be
disconnected if altering the circuitry.
Wired Remote Control
The Wired Remote Control gives you the opportunity to power on/o! the inverter from a distance
(approximately 16.4 ft / 5 m).
Note that the inverter ON/OFF switch should be in the REM position.

Pure Sine Wave
The inverter outputs a pure sine wave similar to the waveform of the grid power. In a pure sine
wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and c leaner
utility-like power.
This technology allows the inverter to supply electronic devices that require a high quality
waveform with little harmonic distortion. In addition, the technology enables the inverter to be
more e#cient than traditional ones, allowing you to use less energy to supply more devices.
The inverter can provide su#cient, stable power for tools, fans, lights, computers, and other
electronics without any interference.
General Safety Information
WARNING
Have the inverter installed by a qualified technician in accordance with the local and nati onal
electric codes (NEC).
There are no serviceable parts for this inverter. Do not disassemble or attempt to repai r the
inverter.
Ensure all connections going into and from the inverter are tight. There may be sparks when
making connections; therefore, there should not be flammable materials or gases near the
installation site.
The inverters are suitable for 24V battery banks ONLY.
Always ensure the inverter is in OFF position and disconnect all AC and DC devices associated
with the inverter.
Never connect the AC output of the inverter directly to an Electrical Breaker Panel or Load
Center which is also fed from the utility power or generator.
Please confirm the polarity of the devices before connection. A reverse polarity contact can
cause injury and damage the device.
Be careful when touching bare terminals of capacitors as they may retain high lethal voltages
even after power is removed.
Do not let the positive (+) and negative (-) terminals of the battery touch each other. Use onl y
deep-cycle sealed lead-acid, flooded, gel, or lithium batteries.
Risk of explosion! Never install the inverter in a sealed enclosure with flooded batteries! Do no t
install in a confined area where battery gases can accumulate.

Be careful when working with large lead acid batteries. Wear eye protection and have fresh
water available in case there is contact with the battery acid.
Overcharging and excessive gas precipitation may damage the battery plates and activate
material shedding on them. Too high of an equalizing charge or too long of one may cause
damage. Carefully review the requirements of the specific battery in use.
VORSICHT
Install the inverter in a well-ventilated, cool, and dry environment. Make sure the f ans of the
inverter and the ventilation holes are not blocked.
Do not expose the unit to rain, moisture, snow, or liquids of any type.
