This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility power and battery power.
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 acceptable range (see specification for the details), this inverter is able to generate power to feed the grid (utility) 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. Do not connect the positive or negative terminal of the solar panel to the ground. See Figure 1 for a simple diagram of a typical solar system with this hybrid inverter.
Note: By following the EEG standard, every inverter sold to German area is not allowed to charge battery from Utility. The relevant function is automatically disabled by the software.
Unpacking & Overview
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package:
Selecting Mounting Location
Consider the following points before selecting where to install:
WARNING!! Remember that this inverter is heavy! Please be carefully when lifting out from the package.
Installation to the wall should be implemented with the proper screws. After that, the device should be bolted on securely.
The inverter only can be used in a CLOSED ELECTRICAL OPERATING AREA. Only service person can enter into this area.
WARNING!! FIRE HAZARD.SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.
The inverter is equipped with several communication ports and it is also equipped with a slot for alternative communication interfaces in order to communicate with a PC with corresponding software. Thisintelligent slot is suitable to install with SNMP card and Modbus card. Follow below procedure to connect communication wiring and install the software.
Please install monitoring software in your computer. Detailed information is listed in the next chapter. After software is installed, you may initial the monitoring software and extract data through communication port.
This display is operated by four buttons.
NOTICE: To accurately monitor and calculate the energy generation, please calibrate the timer of this unit via software every one month. For the detailed calibration, please check the user manual of bundled software.
LCD Information Define
NOTE: If backlight shuts off, you may activate it by pressing any button. When an error occurs, the buzzer will continuously sound. You may press any button to mute it.
This inverter can connect to battery types of sealed lead acid battery, vented battery, gel battery and lithium battery. The detail installation and maintenance explanations of the external battery pack are provided in the manufacturer’s external battery pack of manual.
If using sealed lead acid battery, please set up the max. charging current according to below formula:
The maximum charging current = Battery capacity (Ah) x 0.2
For example, if you are using 300 Ah battery, then, maximum charging current is 300 x 0.2=60 (A). Please use at least 50Ah battery because the settable minimum value of charging current is 10A. If using AGM/Gel or other types of battery, please consult with installer for the details.
Maintenance & Cleaning
Check the following points to ensure proper operation of whole solar system at regular intervals.
WARNING: There are no user-replaceable parts inside of the inverter. Do not attempt to service the unit yourself.
CAUTION: A battery can present a risk of electrical shock and high short-circuit current.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
Correct Connecting Order : Battery - solar panel - load
Disconnect : solar panel - battery - load
