The Hybrid Solar Inverter can not only convert the direct current (DC) generated by solar photovoltaic panels into alternating current (AC) used by households or industrial equipment, but also convert the AC in the power grid into DC and store it in batteries, thereby achieving free switching between off-grid and on-grid modes.
To install a hybrid solar inverter, it's essential to understand the key components of the system, choose an appropriate location for installation, gather the necessary tools and materials, and carefully follow the installation steps.
Solar Panels: Convert sunlight into direct current (DC). The number and quality of panels directly affect the system's energy production.
Inverter: Converts DC electricity from the panels into alternating current (AC) for use in household appliances.Learn more about Solar Inverters.
Battery Storage System: Stores excess electricity generated during the day for use at night or during power outages.
Charge Controller: Regulates the flow of DC electricity into the batteries to prevent overcharging or over-discharging.
Load: Refers to appliances like refrigerators, microwaves, and other devices that consume electricity from the system.
Transformer: Some hybrid systems include a transformer to adjust voltage levels to meet grid requirements or match load demands.
Battery Management System (BMS): Monitors and manages the battery's status. Most hybrid solar inverters support RS485 or CAN bus protocols for communication with the BMS.
RS485 Communication: A commonly used serial protocol for connecting internal components or external devices.
CAN Bus: Suitable for multi-device systems, like connecting multiple inverters or load equipment.
Wi-Fi Functionality: Enables remote monitoring and management. Modern inverters often include Wi-Fi, allowing users to track energy usage, system performance, and other data via apps or web platforms.
1. Ensure good airflow with at least 20 cm (8 inches) of clearance for heat dissipation.
2. Maintain a distance of 20–50 feet (6–15 meters) between the solar panels and the hybrid solar inverter for optimal efficiency.
3. Avoid direct sunlight exposure.
Install in a dry, clean environment to minimize dust accumulation.
4. Keep the hybrid solar inverter away from flammable materials or gases.
5. Place it near the main electrical panel for easier access.
6. Install out of reach of children.

· Add a battery breaker between the battery and the hybrid solar inverter for isolation during faults or maintenance.
· Connect the solar panel DC cables to the hybrid solar inverter's input ports, ensuring correct polarity (positive to positive, negative to negative).
· Place the battery near the hybrid solar inverter, ensure proper grounding, and connect the battery cables to the hybrid solar inverter's battery input ports.
· Inspect all connections to ensure they are tight and correctly aligned.
· Reattach the baffle to the hybrid solar inverter.
· Turn on the system and check the hybrid solar inverter's display for operational data to confirm functionality.
· Use monitoring software or meters to verify real-time performance and ensure the system meets expectations.
Preparation:
Make sure all equipment is intact and read the relevant user manual to understand the installation requirements of the specific model.
Use a multimeter to measure the voltage of the solar panel to ensure that it is in normal working condition.
Install the solar panel in a well-ventilated and sunny location to avoid shadows.
Connect the solar panel:
According to the specifications of the inverter, connect the positive pole (PV+) of the solar panel to the positive input terminal of the inverter and the negative pole (PV-) to the negative input terminal.
Use a cable of appropriate specifications (such as 12 AWG wire) and ensure that the insulation layer at the end of the cable is removed before inserting the cold-pressed terminal and tightening it with a crimping pliers. Make sure all connections are firm and reliable to avoid looseness or poor contact.
Check the connection line:
After completing the connection, use a multimeter again to confirm whether the voltage is correct and ensure that there is no short circuit.
Install the inverter:
Fix the inverter to a wall or other supporting structure to ensure that it is stable and easy to maintain.
Connect the AC output terminal of the inverter to the grid or load equipment.
Preparation:
Make sure the battery meets the requirements of the inverter, such as lithium-ion battery or lead-acid battery.
Check whether the positive and negative poles of the battery are correct to avoid reverse connection.
Find the battery terminals on the hybrid inverter.
Connect the battery:
Connect the positive pole (B+) of the battery to the DC input positive terminal of the inverter, and the negative pole (B-) to the DC input negative terminal.
Use a suitable cable to connect the battery, and make sure the cable length is appropriate to avoid excessive length that causes increased resistance.
Set up the battery management system:
If the inverter supports intelligent battery management function, you can set battery charging current, voltage and other parameters through the LCD display or dedicated software.
Make sure the battery management system can prevent overcharging, over-discharging and short circuit.
Test the battery connection:
Start the inverter and observe the battery status indicator on the LCD display to ensure that the battery is working properly.
Check the network settings:
Make sure the wireless network meets the compatibility requirements of the inverter, such as Wi-Fi or Ethernet connection.
Make sure your hybrid inverter has Wi-Fi capability (check if the Wi-Fi module is installed).
If the inverter supports Wi-Fi, you need to configure the router PIN and network settings.
Connect to wireless network:
Turn on the inverter's Wi-Fi function, select the network and enter the password through the LCD display or dedicated software.
Make sure the inverter can successfully connect to the wireless network and upload data to the monitoring platform through the network.
Remote monitoring and management:
Use a dedicated application for remote monitoring to view the inverter's operating status, battery power and power generation data.
You can set an alarm function to notify users in time when the system is abnormal.
