8kW-12kW Energy Storage Off-Grid Solar Inverter

Key Features & Advantages

1. Efficient power generation

• Dual-channel MPPT: can be able to make solar panel power generation efficiency higher and fully utilize solar energy.
• Wide MPPT voltage range (60V-480V): suitable for different solar panels, without worrying about incompatibility.
• Maximum photovoltaic input voltage 550V: can be well matched with high-efficiency solar modules, and power generation is more stable.
• Output power factor up to 1.0: stable and user-friendly output AC power, applicable to a broad spectrum of devices.

2. Sophisticated energy management

• Dual-channel AC output: can provide power to different devices at the same time, and can intelligently distribute loads and optimize power usage.
• Support grid-connected function: can supplement grid power when peak power is used, and reserve excess power when there is low power usage, reducing electricity bills for you.
• Independent generator interface: The generator can be automatically started and stopped, and the backup power supply is more stable.
• Support up to 9 inverters in parallel: The total power can be 108 kilowatts, which can meet the demand for high power.

3. Intelligent and reliable operation

• Remote monitoring: Check the device status at any time and any location via WiFi and 4G, and adjust the settings remotely.
• ·Intelligent charging and discharging management: Reasonably arrange charging and discharging, extend battery life, and optimize energy utilization.
• ·Seamless switching: Very fast switching between the grid, battery， and generator (single device <20 milliseconds, parallel devices <30 milliseconds), no power consumption lag.

4. Durable and rugged construction

• ·High compatibility: You can use it with both lithium batteries and lead-acid batteries, giving you more choices.
• ·Lightweight and handy: The whole machine only weighs 21.5 kg and is neatly designed and very easy to install.
• ·Efficient heat dissipation: It uses an air cooling mechanism to ensure proper functioning of the equipment even under extreme conditions.
• ·High durability: The level of protection is IP20 and can be adjusted to fit different intricate usage conditions.

 

Application Scenarios

✔Home off-grid system: especially suitable for homes in remote communities, or those who want to reduce their dependency on the power grid, and generate their own electricity for personal use without worrying about power outages.

✔Commercial backup power supply: can provide power support to business enterprises during power outages, allowing business enterprises to operate normally and avoid losses caused by power outages.

✔Industrial power storage: supply energy-hungry plants and factories with the needed energy, and ensure constant power supply for factory operations.

✔Microgrid and hybrid systems: can be easily integrated with solar power, batteries, generators ,and other equipment to form a versatile and reliable power system.

✔Rural power supply and backup power: provide stable power solutions in insecure or remote areas for basic electricity needs.
