1. Introduction
This off-grid PV inverter can provide power to connected loads by utilizing PV power, AC power and battery power. When PV energy is sufficient, it will power connected loads and charge battery. When PV energy is not sufficient, this inverter will power connected loads and charge battery from AC power source. When both PV energy and AC power source are not available, it will provide battery power to connected loads.
Figure 1 Basic Off-Grid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate continuous power from PV solar modules (solar panels), battery, and the utility. When MPP input voltage of PV modules is within 150 VDC to 500 VDC, this inverter is able to generate power to the load and charge battery. This inverter is only compatible with PV module types of single crystalline and poly crystalline. Do not connect any PV array types other than these two types of PV modules to the inverter. See Figure 1 for a simple diagram of a typical solar system with this hybrid inverter.
Note: When PV input voltage is lower than 250V, the power of inverter will de-rate.

Conventions used: WARNING! Warnings identify conditions or practices that could result in personal injury; CAUTION! Caution identify conditions or practices that could result in damaged to the
unit or other equipment connected.
2. Important Safety Warning
Before using the inverter, please read all instructions and cautionary markings on the unit and this manual. Store the manual where it can be accessed easily.
This manual is for qualified personnel. The tasks described in this manual may be performed by qualified personnel only.
General Precaution-
WARNING! Before installing and using this inverter, read all instructions and cautionary
markings on the inverter and all appropriate sections of this guide.
WARNING! Normally grounded conductors may be ungrounded and energized when a ground fault is indicated.
WARNING! This inverter is heavy. It should be lifted by at least two persons.
CAUTION! Authorized service personnel should reduce the risk of electrical shock by
disconnecting AC, DC and battery power from the inverter before attempting any maintenance or cleaning or working on any circuits connected to the inverter. Turning off controls will not reduce this risk. Internal capacitors can remain charged for 5 minutes after disconnecting all sources of power.
CAUTION! Do not disassemble this inverter yourself. It contains no user-serviceable parts. Attempt to service this inverter yourself may cause a risk of electrical shock or fire and will void the warranty from the manufacturer.
CAUTION! To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that the wire is not undersized. Do not operate the Inverter with damaged or substandard wiring.
CAUTION! Under high temperature environment, the cover of this inverter could be hot enough to cause skin burns if accidentally touched. Ensure that this inverter is away from normal traffic areas.

CAUTION! Use only recommended accessories from installer . Otherwise, not-qualified tools may cause a risk of fire, electric shock, or injury to persons.
CAUTION! To reduce risk of fire hazard, do not cover or obstruct the heat sink.
CAUTION! Do not operate the Inverter if it has received a sharp blow, been dropped, or
otherwise damaged in any way. If the Inverter is damaged, called for an RMA (Return Material Authorization).

4. Installation
4-1. Selecting Mounting Location
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials. Mount on a solid surface This inverter can make noises during operation which may be perceived as a nuisance in
a living area.
Install this inverter at eye level in order to allow the LCD display to be read at all times. For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the
side and approx. 50 cm above and below the unit.
Dusty conditions on the unit may impair the performance of this inverter. The ambient temperature should be between 0°C and 40°C to ensure optimal operation.
The recommended installation position is to be adhered to (vertical). For proper operation of this inverter, please use appropriate cables for grid connection. Select an appropriate mounting location. Install the solar inverter in a protected area
that is free of excessive dust and has adequate air flow. Do NOT operate it where the temperature and humidity is beyond the specific limits. (Please check the specs for the limitations.)
This inverter is designed with IP20 for indoor applications only.
4-2. Mounting Unit
Installation to the wall should be implemented with the proper screws. Mount the wall bracket so that the solar inverter can be easily attached to the wall. After that, the device should be bolted on securely.

1. Drill four holes in the marked locations
with four screws.
2. Place the unit on the surface and align the
mounting holes with the four screws.
3. Check if the solar inverter is firmly
secured.
Note: Recommended specs for screws.

5. AC Input Connection
5-1. Preparation
Before connecting to AC input power source, please install a separate AC circuit breaker between inverter and AC power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. NOTE1: Although this inverter is equipped with a fuse (F6 point on PCB, 250VAC/30A), it’s still necessary to install a separate circuit breaker for safety consideration. Please use 250VAC/30A circuit breaker.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC connection. To reduce risk of injury, please use the proper recommended cable size as below. Suggested cable requirement for AC wire
Conductor cross-section (mm2)
AWG no.
≥3.35
10 - 12
5-2. Connecting to the AC Power Source
Step 1: Check the AC voltage and frequency with an AC voltmeter. It should be the same to “VAC” value on the product label.
Step 2: Turn off the circuit breaker.
Step 3: Remove insulation sleeve 8 mm for three conductors. And shorten phase L and neutral conductor N 3 mm. Refer to chart 1.
Step 4: Connect wires according to polarities indicated on terminal block. Be sure to connect PE protective conductor ( ) first.
L→LINE (brown or black)
→Ground (yellow-green)
N→Neutral (blue)
Step 5: Make sure the wires are securely connected.
CAUTION: To prevent risk of electric shock, ensure the ground wire is properly earthed
before operating this inverter no matter the AC input is connected or not.

6. PV Module (DC) Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker
between inverter and PV modules. NOTE: Please use 600VDC/25A circuit breaker. Please follow below steps to implement PV module connection:
Step 1: Check the input voltage of PV array modules. The acceptable input voltage of the solar inverter is 250VDC - 450VDC. This system is only applied with one string of PV array. Please make sure that the maximum current load of PV input connector is 13A.
Step 2: Disconnect the circuit breaker.
Step 3: Remove insulation sleeve 10 mm for positive and negative conductors. Refer to chart 3.
Step 4: Check correct polarity of connection cable from PV modules and PV input connectors. Then, connect positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative pole (-) of connection cable to negative pole (-) of PV input connector. Refer to Chart 4.
Step 5: Make sure the wires are securely connected.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the system before wire connection.
WARNING: This inverter is only compatible to two types of PV modules: single crystalline and poly crystalline. To avoid any malfunction, do not connect any PV modules with possibility of leakage current to the inverter.
