The wiring diagram only shows the key components in a typical DC-coupled off-grid energy
storage system for the illustrative purpose. The wiring might be different depending on the
system configuration. Additional safety devices, including disconnect switches, emergency
stops, and rapid shutdown devices, might be required. Wire the system in accordance with the
regulations at the installation site.
The connection of AC IN ports vary depending on the connected grid systems. For single-
phase 120V grid systems, only AC IN L1 and AC IN N ports are used for the input. For split-phase
120V/240V grid systems, AC IN L1, AC IN L2, and AC IN N ports are used for the input.

3. Preparation
3.1. Plan a Mounting Site
The inverter charger requires adequate clearance for installation, wiring and ventilation. The minimum
clearance is provided below. Ventilation is highly recommended if it is mounted in an enclosure. Select a
proper mounting site to ensure the inverter charger can be safely connected to the battery and grid/AC
generator with the relevant cables.

Risk of explosion! Never install the inverter charger in a sealed enclosure with flooded batteries!
Do not install the inverter charger in a confined area where battery gases can accumulate.
The inverter charger should be installed on a vertical surface protected from direct sunlight.
Keep the inverter charger out of the reach of children and animals.
Do not expose the inverter charger to flammable or harsh chemicals or vapors.
Make sure that the inverter charger is installed in a place at ambient temperature from -4°F to
140°F (-20°C to 60°C).
Make sure that inverter charger is installed in an environment with relative humidity between 0%
and 95% and no condensation.
If the inverter charger is installed improperly on a boat, it may cause damage to components of
the boat. Have the inverter charger by a qualified electrician.
The inverter charger cannot operate at full load in ambient temperatures above 113°F (45°C).
The inverter charger should be as close to the battery as possible to avoid voltage drop due to
long cables.
It is recommended that all cables (except communication cables) should not exceed 10 meters
(32.8 feet) because excessively long cables result in a voltage drop. The communication cables
should be shorter than 6 m (19.6 feet).
The cable specifications listed in the user manual account for critical, less than 3% voltage drop
and may not account for all configurations.
Ensure the inverter charger is firmly grounded to a building, vehicle, or earth grounded. Keep the
inverter charger away from EMI receptors such as TVs, radios, and other audio/visual electronics
to prevent damage / interference to the equipment.

— 7 —
To ensure good ventilation and optimal system performance, we recommend mounting the inverter
charger vertically (terminals down) on a wall or horizontally on the floor.
3.2. Check the Inverter Charger
1. Inspect the inverter charger for any visible damage including
cracks, dents, deformation, and other visible abnormalities. All
connector contacts shall be clean, free of dirt and corrosion, and
dry.
Do not use the inverter charger if there is any visible damage.
Do not puncture, drop, crush, penetrate, shake, strike, or step on the inverter charger.
There are no serviceable parts in the inverter charger. Do not open, dismantle, repair, tamper with,
or modify the inverter charger.

1. Inspect the battery for any visible damage including cracks,
dents, deformation, and other visible abnormalities. All terminals
shall be clean, free of dirt and corrosion, and dry.
The inverter charger can only be connected to deep-cycle gel-
sealed lead-acid batteries (GEL), flooded lead-acid batteries
(FLD), sealed lead-acid batteries (SLD/AGM) or lithium iron
phosphate batteries (LI).
The inverter charger provides overcurrent protection by detecting
the DC input current from the battery in real time. When the
battery input reaches 400A, the inverter charger automatically
shuts down the battery input to prevent damage caused by
excessively high current.

2. Check battery system voltage.
This inverter charger supports
a maximum system voltage
of 17V. Read the user manual
of the specific battery for
battery voltage parameters,
and calculate the voltage of the
battery or battery pack system
according to the formula to
ensure that it does not exceed
17V.
The inverter charger operates normally at a range between 11V and 15.8V and allows a battery input
from 9V to 17V with operating status specified below:

Do not connect batteries rating higher than 17V to the inverter. Doing so will damage the inverter
charger.
In the formula, U represents the battery voltage, and 1, 2 or 3 represents the battery number
respectively.
3. Inspect the NH2 Fuse or ANL Fuse for any visible damage
including cracks, dents, deformation, and other visible
abnormalities. All terminals shall be clean, free of dirt and
corrosion, and dry.
Do not use the NH2 Fuse or ANL Fuse if there is any visible damage.

4. Inspect the Anderson Adapter Cable or Battery Adapter Cables
for any visible damage including cracks, dents, deformation, and
other visible abnormalities. All connector contacts shall be clean,
dry, and free of dirt and corrosion. All ring terminals are fastened
to the cables.
Do not use the Anderson adapter cable or battery adapter cables if there is any visible damage.
3.4.Check the AC Loads (Appliances)
It works seamlessly with both 120V and 240V grid power systems and outputs 120V or 240V AC voltage
in accordance with the AC input voltage. Choose proper accessories and cables based on the rated

A ground fault circuit interrupter, or GFCI, is a device that helps protect people from electric shock
by de-energizing a circuit or part of a circuit within a specified time if a current to ground exceeds a
predetermined value that is less than that required to operate the overcurrent device (circuit breaker or
fuse) on the service circuit. GFCIs are typically required in wet or damp locations.
The following table lists GFCIs that meet specifications and will function properly when connected to
the AC Outlets of the inverter charger.
