2. Installation Instructions
2.1 General Installation Notes
Please read the entire installation instructions to get familiar with the installation steps before
installation.
Be very careful when installing the batteries, especially flooded lead-acid batteries. Please wear
eye protection, and have fresh water available to wash and clean if any battery acid contact.
Keep the battery away from any metal objects, which may cause a short circuit of the battery.
Explosive acid battery gases may come out from the battery during charging, so make sure
ventilation condition is good.
Ventilation is highly recommended if mounted in an enclosure. Never install the inverter/charger
in a sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and
destroy the inverter/charger circuits.
The lead-acid battery is only recommended. For other kinds, please refer to the battery
manufacturer.
Loose connections and corroded wires may result in high heat that can melt wire insulation, burn
surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in motion.
Select the system cables according to 5A/mm2or less current density followingArticle 690 of the
National Electrical Code, NFPA 70.
For outdoor installation, keep out of the direct sunshine and rain infiltration.
High voltage still exists inside the inverter/charger after switching off the power switch. Do not
turn on or touch the internal units and conduct the associated operation only after discharging
the electric capacity.
Do not place the inverter/charger in a damp, oily, inflammable, and explosive or severe
environment with a large amount of dust accumulation.
Prohibit reverse connection at DC input end; otherwise, it may damage the equipment, or
unpredictable danger will occur.
The utility input and AC output are of high voltage, do not touch the wire connection.

The wire size is only for reference. Suppose a long-distance exists between the PV
array and the inverter/charger or between the inverter/charger and the battery. In that
case, larger wires shall be used to reduce the voltage drop and improve the system
performance.
The above wire and the circuit breaker size are recommended only; please choose the
appropriate wire and circuit breaker according to the practical situation.
NOTE：The cable lugs refer to the cardboard in the package.

Installation steps：
Step1：Determination of Installation Location and heat-dissipation Space
When installing the inverter/charger, ensure enough air flowing through the heat sink. Please leave
at least 150mm clearance away from the upper and lower edges. Please see Figure 2-1: Mounting.
WARNING: Risk of explosion!
Never install the inverter/charger with flooded batteries in a sealed enclosure! Do not
install the device in a confined area where battery gas can accumulate.
Step 2：Take down the terminal protective cover
Step 3：Wiring
Connect the system in order of battery load PV array GroundUtility
following Figure 2-3: Wiring Diagram. Disconnect the system in reverse order.

Danger, High-voltage! Utility input, AC output, and PV array will produce dangerous
voltage. Ensure to disconnect the circuit breaker/ fuse before wiring.
Do not turn on the circuit breaker/ fuse when wiring, and at the same time, ensure that
the poles’wirings are correctly connected.
A circuit breaker must be installed at the battery end. For selection, refer to Section 2.3,
"Wire and Circuit Breaker."
If the inverter/charger is to be used in an area with frequent lightning strikes, installing an
external surge arrester at the PV input is recommended.
Grounding
A grounding connection must be made when the utility is connected to the inverter/charger. The
inverter/charger has a dedicated grounding terminal, as shown in Fig. 2-3, and the grounding must
be reliable. The grounding wire has to stay consistent with Recommended wire for AC output. The
grounding point shall be as close as possible to the inverter/charger; the grounding wire shall be as
short as possible.
AC output, Ground, and PV wiring terminal use way:
①When wiring, do not close the circuit breaker. It is necessary to use a slotted screwdriver to
unscrew the screws for connecting their corresponding wires.
②When removing the wirings, first the integrated machine must stop working. Then the screws
shall be unscrewed by using a slotted screwdriver to dismantle their corresponding wires.
Step 4：Install the terminal protective cover
Step 5：Connect accessory
Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect one end of the remote temperature sensor cable to the interface⑥
and place the other end close to the battery.
Connect the temperature sensor, the inverter/charger is compensated according to the
ambient temperature.
Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect the accessories, monitor the system status, and set the parameters via PC
software or APP software.

①Connect the circuit breaker at the battery end.
②Turn on the switch, then the inverter indicator is on.
③Turn on the breaker of PV array and Utility.
④Turn on the AC load when the AC output is normal.
When supplying power for different AC loads, it is recommended to turn on the load
with a large impulse current. And then turn on the load with a smaller impulse current
after the load output is stable.
If the inverter/charger is not operating properly or the LCD or the indicator shows an
abnormality, please refer to 5 "Troubleshooting" or contact our after-sales personnel
